  • 00:00All right, so again, welcome this evening.
  • 00:03It's really a pleasure to have everybody
  • 00:05here and thank you for being here.
  • 00:08So first I have one disclosure
  • 00:10which is not relevant to what
  • 00:12we're going to be talking about.
  • 00:15And actually I had my slides backwards,
  • 00:17so I apologize.
  • 00:18So first I want to start by
  • 00:20thanking Connecticut brain tumor
  • 00:22alliance and the national brain
  • 00:24tumor society who have partnered
  • 00:25with us in support of this seminar.
  • 00:28They are wonderful organizations who.
  • 00:30Really help and support patients with
  • 00:32brain tumors and we are grateful for
  • 00:35their support and their partnership.
  • 00:37I want to talk a little bit and
  • 00:39introduce Susie Barris to all of you.
  • 00:41So she is become my dear friend.
  • 00:44She was my patient and she was practicing
  • 00:48as a pediatrician in Connecticut.
  • 00:52Very beloved pediatrician and one
  • 00:54day she had a seizure in her office.
  • 00:57She was then diagnosed with a glioblastoma
  • 01:00in her motor strip and so she was
  • 01:03transferred to a local hospital and was
  • 01:06told that her tumor was inoperable.
  • 01:08Because of its location in the motor
  • 01:10strip and that a biopsy was offered,
  • 01:13Susie,
  • 01:13being a physician,
  • 01:14thought to to see if maybe there
  • 01:17were some options or alternatives,
  • 01:19or she sought opinions throughout
  • 01:21the Northeast Corridor.
  • 01:22I was thankful and privileged enough to
  • 01:24be the one to end up caring for her.
  • 01:27I performed in awake craniotomy on her.
  • 01:29We removed all of the tumor safely and
  • 01:31this is a picture of her and I at the
  • 01:34Connecticut brain tumor lions path of hope.
  • 01:37Two weeks after her surgery.
  • 01:39They have, uh,
  • 01:40their annual 5K.
  • 01:41She ran it twice and I walked it
  • 01:44once so she is an amazing person.
  • 01:47And in gratitude for her success
  • 01:50she is now about almost about
  • 01:53four years after her surgery.
  • 01:56In her gratitude,
  • 01:58she has been incredibly generous
  • 02:01to us and to our program,
  • 02:03and so we recently named our
  • 02:05Nurse Surgical Oncology program
  • 02:06in her honor and her fund support.
  • 02:09The seminar,
  • 02:09as well as other efforts to try
  • 02:11to educate the community patients
  • 02:13and providers about the importance
  • 02:15of of brain tumor care and and
  • 02:18brain tumor management,
  • 02:20so very grateful to her
  • 02:22and to her friendship.
  • 02:24So tonight,
  • 02:24my portion of the talk is going
  • 02:26to be talking about surgical
  • 02:28strategies for primary brain tumors.
  • 02:30We have Zach Corbin who's going
  • 02:32to follow me talking about neural
  • 02:34oncology approaches.
  • 02:35Bruce Mcgibbons talking about
  • 02:37radiation oncology approaches,
  • 02:39and then the probably the most
  • 02:41important aspect of the talk.
  • 02:43Brian Jin talking about from social work,
  • 02:46talking about the management and
  • 02:48support of patients and their families.
  • 02:50So again, one disclosure that's not relevant,
  • 02:53so we are fortunate to perform the
  • 02:55most number of brain tumor surgeries
  • 02:57each year in Connecticut and care
  • 02:59for the highest volume of patients.
  • 03:01We do try to partner with the Community
  • 03:04in that a lot of the Community,
  • 03:05neurosurgeons and other providers,
  • 03:07will refer patients to us for
  • 03:09more complex cases, and I'll show some
  • 03:11examples of where and how we can.
  • 03:14We can be helpful.
  • 03:15All of the tumors that we operate on
  • 03:17undergo what we call whole exome sequencing,
  • 03:20which is a really.
  • 03:21Next generation sequencing technique
  • 03:23that allows us to understand the tumor
  • 03:26from a molecular standpoint and that
  • 03:28enables us to to treat people from a
  • 03:30very precise and personalized manner.
  • 03:33And we discussed every patient in
  • 03:35our multidisciplinary tumor board,
  • 03:36which I direct and everybody here attends,
  • 03:39as well as our precision
  • 03:40brain tumor board each week.
  • 03:42These are just an example of some cases.
  • 03:44I always show my patients
  • 03:46the preop and POSTOP scans.
  • 03:48I don't know if you're seeing
  • 03:49my my mouse or not,
  • 03:51but preop is on the left post OP is on
  • 03:54the right and you can see for instance,
  • 03:56the glioblastoma Mirren and in
  • 03:58the motor strip that was gross,
  • 04:01totally resected,
  • 04:02some more aggressive meningiomas
  • 04:04that we manage,
  • 04:05and take care of again
  • 04:07vestibular schwannomas,
  • 04:08which we'll talk a little bit
  • 04:10about interventricular tumors,
  • 04:11and again, pre and postop.
  • 04:13With the comparisons with showing
  • 04:15the extent of resection and we'll
  • 04:17talk about how removing as much tumor
  • 04:20as safely as possible is really the
  • 04:22goal to any type of of neurosurgical
  • 04:24care for brain tumor patients.
  • 04:26So the goal of primary brain
  • 04:28tumor surgery of course,
  • 04:29to establish a diagnosis and and to
  • 04:33establish sorry and to establish
  • 04:35an accurate diagnosis to maintain,
  • 04:38improve quality and quantity of life.
  • 04:41And by what I.
  • 04:41What I mean by that is that there's
  • 04:43great evidence that shows the more tumor.
  • 04:46We're able to remove safely.
  • 04:48The better the patient does,
  • 04:50this really has shown effect
  • 04:52across all tumor types.
  • 04:54Maybe without the the
  • 04:55exception of of lymphomas.
  • 04:57In small cell lung cancer,
  • 04:59but otherwise brain tumors
  • 05:01benefit from being gross,
  • 05:02totally resected,
  • 05:03and patients benefit from the resection while
  • 05:06maintaining their neurological function,
  • 05:08or even improving their
  • 05:10neurological function.
  • 05:11How do we do that?
  • 05:13And so similar to Susie's tumor
  • 05:14patients can be told that they have
  • 05:17an inoperable tumor because it's in
  • 05:19in an eloquent part of the brain,
  • 05:21an eloquent meaning a highly
  • 05:22functioning part of the brain,
  • 05:24and So what are the secrets to
  • 05:26the success we have all the the
  • 05:28gadgets and and gazebos that that
  • 05:30that gadgets and gizmos that that
  • 05:32we need in our state of the art
  • 05:34operating rooms with GPS systems and
  • 05:36ultrasounds were the only center in
  • 05:38the state to have an intraoperative MRI,
  • 05:41which I'll show the benefit of.
  • 05:43But really,
  • 05:43I think a lot of it comes down
  • 05:46to expertise and experience,
  • 05:48and in fact that has a lot to do with
  • 05:51more sophisticated microsurgical techniques,
  • 05:53and especially when we're talking
  • 05:56about preserving function.
  • 05:57And really the gold standard for
  • 05:59that is is neuromonitoring or use of
  • 06:02neuromonitoring and functional mapping,
  • 06:04as well as a weak surgery,
  • 06:05which I'll show some examples of.
  • 06:08This was a slide that was given
  • 06:09to me by
  • 06:10the Chair of mass general Neurosurgery,
  • 06:12and I I really like it because I think it.
  • 06:14It speaks volumes.
  • 06:16This is as you can see,
  • 06:18as the case volume increases and this is
  • 06:22the percentage of of cranial specialization.
  • 06:24What this shows is that surgeons who do
  • 06:27higher volume and are more specialized
  • 06:29in a particular area of neurosurgery,
  • 06:32cranial versus spine,
  • 06:33that would even argue tumor versus
  • 06:36other aspects of neurosurgery.
  • 06:38Have better outcomes in terms of
  • 06:40their patients, and that's certainly
  • 06:42something that we see here.
  • 06:44I have a short video which I
  • 06:47hope you don't mind me sharing.
  • 06:48Unfortunately I have to pull it up elsewhere,
  • 06:51but this is a great example and
  • 06:53I've I've shown this before,
  • 06:55so forgive me if you've seen my talks
  • 06:57before and have seen the video,
  • 06:59but I think it's a real great
  • 07:01example of what we're able to do.
  • 07:06205 Sixty one can you hear it OK?
  • 07:09Surgery, waking up in the middle of the
  • 07:11procedure and knowing what's going on.
  • 07:13But in some cases that can be a lifesaver,
  • 07:15lifesaver and necessary.
  • 07:16We're going to explain that in a moment,
  • 07:18but first we do want to introduce you
  • 07:20to a man named Andy Andy is a husband
  • 07:22and father of two kids and a nurse.
  • 07:24Another interesting fact about him,
  • 07:26he's also a professionally trained singer.
  • 07:29He's even performed with his
  • 07:30church choir at Carnegie Hall,
  • 07:32but Andy felt his entire life come to a halt
  • 07:35when he was diagnosed with brain cancer.
  • 07:37He needed surgery to remove
  • 07:38as much of a tumor.
  • 07:40It's possible that tumor in the part
  • 07:42of his brain that controls speech and,
  • 07:44yes, singing.
  • 07:45That's where a special surgery comes in.
  • 07:47Surgeons at Yale,
  • 07:48New Haven Smilow Cancer Hospital
  • 07:50have perfected a procedure
  • 07:51called in a weight craniotomy.
  • 07:53They invited us into the operating
  • 07:55room and we did not hesitate to see
  • 07:57this incredible procedure first hand.
  • 08:02In an operating room at Yale,
  • 08:04New Haven Hospital.
  • 08:07Doctors are working to remove
  • 08:08the tumor from the brain of
  • 08:10a 31 year old man named Andy.
  • 08:12He is a singer.
  • 08:15A husband and father of two for most
  • 08:19surgeries waking up in the middle of
  • 08:21the operation would be a disaster.
  • 08:26And anesthesiologist doing his best
  • 08:29to make sure Andy does just that.
  • 08:33They still surgeons have drilled
  • 08:35through his skull and have already
  • 08:37begun to remove part of the tumor.
  • 08:39Located on the left side
  • 08:41of his temporal lobe.
  • 08:42The area which controls language.
  • 08:46Medical staff puts a microphone on him.
  • 08:49It's not for our cameras,
  • 08:50it's so the entire room,
  • 08:53including the operating surgeon,
  • 08:54can hear what Andy has to say.
  • 08:59The procedure is called an awake craniotomy.
  • 09:03I was telling you earlier I I don't know
  • 09:05if it's from the brain surgery or the fact
  • 09:08that I have to have a couple of copies
  • 09:11for neurophysiologist. Brook Callahan
  • 09:13sits next to him and begins her work. I
  • 09:16am going to say a sentence and I
  • 09:18want you to repeat it after me.
  • 09:20The seashore smells like salt.
  • 09:23It's like. Action can be heard
  • 09:26on a speaker throughout the room.
  • 09:28Neurosurgeon Doctor Jennifer moliterno.
  • 09:33Has mastered multitasking,
  • 09:35operating and listening.
  • 09:38Great Doctor Moliterno and her
  • 09:40team worked diligently to remove
  • 09:42as much of the tumor as possible.
  • 09:44What she can't see are critical
  • 09:46microscopic language fibers which
  • 09:48are splayed over the tumor.
  • 09:49The best way to try to remove
  • 09:51as much tumor and preserve his
  • 09:53language is to do it with him away.
  • 09:55Get too close to those critical fibers.
  • 09:58You'll know it. What can you do in a chair?
  • 10:05I don't know. Yeah,
  • 10:07a little bit of confusion, so that's
  • 10:09a great way to me to tell me to stop.
  • 10:13And so even though there might
  • 10:14be a little bit of tumor there,
  • 10:16the risk and benefit of removing
  • 10:18that tumor and having him not
  • 10:19speak for the rest of his life.
  • 10:21Tells you exactly what the right decision is.
  • 10:24If he was asleep,
  • 10:25I would have had no idea.
  • 10:26As Doctor Moliterno continues
  • 10:28operating at a safer spot and he
  • 10:31surprises us when this happens.
  • 10:39He does in the middle of surgery.
  • 10:42Andy's a classically trained
  • 10:43singer, shares his talent.
  • 10:502 1/2 hours into the procedure,
  • 10:52doctor Moliterno decides
  • 10:53it's time to wrap up.
  • 10:55The surgeons are done with the
  • 10:56first part of the surgery.
  • 10:57So what's happening now is they're
  • 10:59bringing in an MRI machine and
  • 11:00they're going to look at the work
  • 11:02that they did and see how much of
  • 11:04the tumor they were able to remove.
  • 11:08We go into another room that
  • 11:10are able to sit with Doctor
  • 11:11Moliterno as she analyzes her work.
  • 11:14The before kierans think tumor and after.
  • 11:21You don't have to go back in and feel
  • 11:24satisfied pending a week allowed us to get
  • 11:27that outcome and preserve this function.
  • 11:30Now Andy was back home with his
  • 11:32family two days after surgery,
  • 11:34five days after the surgery,
  • 11:36he was able to sing at his son's baptism.
  • 11:38He's also saying again with his
  • 11:41church choir and the Yale Camerata,
  • 11:43which is a professional choir.
  • 11:45Just a couple of weeks ago, Andy is
  • 11:47undergoing chemotherapy and radiation,
  • 11:48but he does say he's feeling good.
  • 11:51And, of course, warm wishes to him.
  • 11:53He is just.
  • 11:56So that is a great example in my
  • 11:58mind as to why we do what we do
  • 12:01and how we can really push the
  • 12:03limits from a surgical perspective.
  • 12:09OK, another example of a patient of
  • 12:12mine who underwent 10 away craniotomy
  • 12:14and so this was an in another man
  • 12:17who presented with language trouble.
  • 12:20He was at a different hospital
  • 12:23and outside hospital and you can
  • 12:25see here was his initial scan.
  • 12:27He had a glioblastoma just around
  • 12:29his his language area and that
  • 12:31was prohibiting him from speaking.
  • 12:33You can see that he underwent a
  • 12:36postop MRI just a short time.
  • 12:38After and really there was not much tumor,
  • 12:41if any that was removed,
  • 12:42and so they had achieved a diagnosis
  • 12:45of glioblastoma,
  • 12:46but he was then referred to
  • 12:48me because as you can imagine,
  • 12:50which Zach and Bruce will will
  • 12:52get to it can be quite hard to
  • 12:54to radiate an area such as this,
  • 12:56or to get patients through through
  • 12:58chemotherapy when there's that much
  • 13:00mass and and Mass Effect and and edema,
  • 13:02especially near critical language structures.
  • 13:05So we ended up getting a functional
  • 13:07MRI similar to Andy. We kept him.
  • 13:10Awake during surgery and we were
  • 13:11able to remove the tumor and his
  • 13:14language improved considerably.
  • 13:15Not all patients need to be awake
  • 13:18during surgery in order for us
  • 13:20to safely remove and and get the
  • 13:22the maximal extent of resection.
  • 13:24This is one of my favorite stories
  • 13:26and I have a lot that are similar,
  • 13:29but I think this one really highlights
  • 13:32the multidisciplinary effort that
  • 13:34that we provide on every patient.
  • 13:36So this is a gentleman in 2013.
  • 13:38As you can see.
  • 13:39He presented to another hospital.
  • 13:42And and underwent a biopsy for this tumor.
  • 13:46That's located here,
  • 13:47turned out to be a glioblastoma.
  • 13:49He was told that the mass was
  • 13:51too risky to remove.
  • 13:52He then was referred to me for
  • 13:54consideration of another opinion.
  • 13:56I thought that this could be safely removed,
  • 13:59and so we did, and even for someone like me,
  • 14:02who does brain tumor surgery every day,
  • 14:05you can still get fooled and
  • 14:06you can still miss some tumor.
  • 14:08And so this is an example of
  • 14:09our interoperative MRI,
  • 14:10which you can see here.
  • 14:12That's housed in our operating
  • 14:14room and a little bit of tumor I
  • 14:16left behind that got tucked and
  • 14:17hidden underneath the brain.
  • 14:19So while he was asleep on the table
  • 14:21after I removed most of the mass,
  • 14:23we got the intraoperative MRI saw that
  • 14:25and I went back and was able to resect it.
  • 14:28This pathology was confirmed as GPM,
  • 14:31showing an unmethylated MGMT status,
  • 14:34which is usually a poor prognostic factor.
  • 14:37His care was then provided by
  • 14:39Yocom bearing our neuro oncologist,
  • 14:41as well as Renji.
  • 14:43Who had the patient on our standard
  • 14:46of of care?
  • 14:47Stoop radiation and temozolomide and
  • 14:50one of our fantastic homegrown Yale
  • 14:54clinical trials that Ranjeet was Pi
  • 14:57and and directed and and and really found it.
  • 15:01He was enrolled on.
  • 15:02He then was enrolled on other clinical
  • 15:04trials that we offer and then switched
  • 15:06on various chemotherapies until he
  • 15:08progressed and when he did he welcome
  • 15:11sent him back to me with this recurrence.
  • 15:13So I operated on him again and here
  • 15:16you can see we did a wider resection
  • 15:18and of course pathology was the same
  • 15:20but the whole exome sequencing that
  • 15:22we performed that really helps us
  • 15:25understand the tumors better showed
  • 15:27he had what we call a hyper mutated
  • 15:29phenotype and the significance of
  • 15:31this is that we know based on the
  • 15:33literature that these tumors tend to be
  • 15:36more susceptible to immune checkpoint
  • 15:38inhibitors and so he was then started on
  • 15:41nivolumab and then also with Avastin.
  • 15:43Intermittently,
  • 15:44and he is currently about 8 1/2 years
  • 15:47from his initial time of diagnosis and
  • 15:50I love this story and when I presented
  • 15:52I always say that this is in no way
  • 15:55and I had rejected him one other time.
  • 15:57Sorry I forgot to mention that I in
  • 15:59no way I'm saying that all of our GBM
  • 16:02patients will survive 8 1/2 years or longer.
  • 16:04I really do wish that was the case,
  • 16:07but he is a great example of how
  • 16:09I believe if he had stopped it.
  • 16:11Just biopsy, there's no way in my mind.
  • 16:14That he would still be alive 8
  • 16:171/2 years after a biopsy.
  • 16:18And so this is a great example of how when
  • 16:20we work together with aggressive surgery,
  • 16:23maximal safe resection even a few times,
  • 16:26we can really push the limits of
  • 16:28what we can do with with the other
  • 16:31clinical trials and other adjuvants.
  • 16:33This is a more recent example
  • 16:35of of a patient who was seen at
  • 16:38another hospital in Connecticut.
  • 16:40He had this large tumor that you can
  • 16:42see here in his fourth ventricle.
  • 16:44This actually caused some obstruction
  • 16:46of of fluid,
  • 16:47so at the outside hospital he underwent
  • 16:49a placement of a shunt to address the
  • 16:52management and build up of the fluid and
  • 16:55also underwent a biopsy of the mass.
  • 16:57The biopsy showed that it
  • 16:58was a malignant tumor,
  • 17:00but unfortunately it wasn't
  • 17:02able to to characterize.
  • 17:03What type of the tumor it was?
  • 17:06And so this patient was followed
  • 17:08with a serial scan a few months later
  • 17:10that showed increase in size of the
  • 17:13tumor and further backup of fluid.
  • 17:15Despite the shunt he was referred
  • 17:17to me for surgical resection.
  • 17:19We were able to remove all of the tumor
  • 17:21and now we can target his treatment better.
  • 17:24Now knowing exactly what type of
  • 17:26tumor it is and also the shunt was
  • 17:28removed because he doesn't need it.
  • 17:30Given the fact that the tumor was removed
  • 17:32and the backup of fluid was alleviated.
  • 17:34So again,
  • 17:35another great example for diagnosis how it
  • 17:38can really be helpful in guiding management.
  • 17:41The maximal set extent of resection doesn't
  • 17:45necessarily apply just to malignant tumors,
  • 17:48and so this is an example of a
  • 17:50vestibular schwannoma patient
  • 17:51and acoustic neuroma patient,
  • 17:53and these tumors are are 99.9% benign,
  • 17:57and so they're not malignant,
  • 17:58but they're tricky and that they
  • 18:00occur next to the brain stem,
  • 18:02and they have a very intimate
  • 18:04association and relationship with
  • 18:06the facial nerve,
  • 18:07and so this patient presents it elsewhere.
  • 18:09He underwent a surgery by another.
  • 18:12Surgeon and this is his preoperative scan.
  • 18:14This is his post operative scan.
  • 18:16Three months later in 2012 and you can see
  • 18:18not much of a difference between the two.
  • 18:21Not much tumor had been removed.
  • 18:23They continued to monitor this and in 2017
  • 18:27in conjunction with another radiation
  • 18:30oncologist ended up giving focused
  • 18:33radiation or gamma knife radiosurgery.
  • 18:35She went on about a year later
  • 18:38to start experiencing this,
  • 18:40which is pretty bad.
  • 18:42Swelling in her brainstem.
  • 18:43As a result,
  • 18:45she became pretty debilitated by this tumor,
  • 18:48so much so that she required very,
  • 18:50very high dose steroids,
  • 18:51which led to a steroid myopathy which led
  • 18:54to significant muscle wasting and weakness.
  • 18:57She was confined to a wheelchair,
  • 18:59and Zach was actually became involved
  • 19:00with her care at that point,
  • 19:02and and kindly referred
  • 19:04her to me when he did this.
  • 19:06Was her preoperative scan and that was
  • 19:08when he had become involved with her care?
  • 19:10You can still see the swelling in the
  • 19:12brain stem over here and we took her
  • 19:15to surgery and got a nice resection.
  • 19:17So another example where working
  • 19:20with people and and providing the
  • 19:23best possible surgical outcome
  • 19:26really does impact people's lives.
  • 19:29Another type of brain tumor that
  • 19:32everyone usually thinks of as being
  • 19:35benign as meningioma and we at Yale
  • 19:37have really done a lot of work to
  • 19:39understand these tumors and the
  • 19:41biology of these tumors and why
  • 19:43sometimes they don't behave as
  • 19:45benign as as one would think.
  • 19:47So this is another patient who
  • 19:49in 2015 underwent a resection.
  • 19:52I don't have those films,
  • 19:54but he had what we call a convexity
  • 19:57meningioma and so another.
  • 19:58Hospital in 2015 underwent resection.
  • 20:01Was told it was a grade one meningioma,
  • 20:03not to be worried about it.
  • 20:05It was removed and he can go about his life.
  • 20:08He ended up having some weakness
  • 20:10due to as you can see,
  • 20:11some swelling in 2017 that was
  • 20:15associated with regrowth of the
  • 20:17tumor and so he got this scan.
  • 20:19He saw a few other surgeons not me at
  • 20:21the time and the decision was to to
  • 20:24do gamma knife radiosurgery targeted.
  • 20:26Then two years after.
  • 20:28The radio surgery he progressively worsened.
  • 20:31He was confined to a wheelchair
  • 20:34with weakness.
  • 20:35The tumor had grown more and he had
  • 20:38intractable seizures at that point.
  • 20:39In 2019, he was sent to me.
  • 20:41This was a pretty straightforward surgery,
  • 20:43despite the radiation,
  • 20:44and we were able to roast, totally remove it.
  • 20:48His weakness improved,
  • 20:49and his seizures went away.
  • 20:50But the question that that I have and
  • 20:52that we've been asking here at Yale,
  • 20:54from a research perspective is,
  • 20:56could this have been better
  • 20:57predicted or manage the first time?
  • 20:59And the answer is yes,
  • 21:00and I'll show you briefly why.
  • 21:02So the general lab,
  • 21:03as well as others has really
  • 21:06understood the genomics underlying
  • 21:08sporadic meningiomas and we now know
  • 21:11about 80 or 85% of sporadic
  • 21:13meningiomas are caused by mutation.
  • 21:16Somatic mutations in these genes,
  • 21:19and so the most common and in the
  • 21:21interest of time I won't get into
  • 21:23everything but the most common
  • 21:25mutation underlying sporadic
  • 21:26meningiomas is somatic mutation.
  • 21:29Involving NF2 with or without
  • 21:31chromosome 22 loss.
  • 21:32These this, this abnormality has been
  • 21:35seen as part of the pathway to more
  • 21:39aggressive meningioma formation,
  • 21:41and I'll talk about that in a
  • 21:42few minutes and so when we think
  • 21:44of grade one meningiomas,
  • 21:46there's also grade 2 meningiomas
  • 21:48and grade 2 meningiomas can either
  • 21:50arise as grade 2 meningiomas,
  • 21:52which we call denova with
  • 21:55certain genomic characteristics,
  • 21:56or they can progress from low grade.
  • 21:59High grade, very similar to gliomas.
  • 22:03Part of the work that I have focused
  • 22:05on is the clinical correlations and so
  • 22:08initially and and we've revised this
  • 22:10even even more so to be more inclusive.
  • 22:12More recently is localizing the
  • 22:15meningioma subgroups based on genomic
  • 22:18mutation with intracranial location,
  • 22:21and so I use this all the time in the
  • 22:23sense that when patients come to my
  • 22:25clinic based on where their tumor where,
  • 22:27their meningeal might is located
  • 22:29in their head,
  • 22:30I can predict with a pretty
  • 22:32good degree of certainty.
  • 22:33And the underlying genomic mutation.
  • 22:36And so why is that relevant?
  • 22:38Because we've gone on with thanks in
  • 22:40part to the Connecticut brain tumor
  • 22:42alliance and their support of our work
  • 22:44to understand the clinical relevance.
  • 22:47And so these genomic subgroups
  • 22:48we have found to be linked to
  • 22:52various clinical manifestations,
  • 22:53whether that's seizure.
  • 22:55Whether that's also to do
  • 22:57with histological subtypes,
  • 22:58or Bony involvement, etcetera,
  • 23:00we have been able to uncover that
  • 23:03one area I wanted to touch upon,
  • 23:05and I apologize for the.
  • 23:06This slide it was.
  • 23:07We were the first to publish
  • 23:09on recurrence being related to
  • 23:12meningioma molecular subgroup,
  • 23:14and so again very busy slide,
  • 23:16but the take home message is that we
  • 23:19identified for the genomic subgroups
  • 23:21with more aggressive clinical
  • 23:23behavior in terms of recurrence,
  • 23:26and so specifically those
  • 23:27tumors with an NF2 mutation,
  • 23:30those with an A KT1 mutation or
  • 23:32other molecules involving the Pi 3
  • 23:35kinase signaling pathway, hedgehog.
  • 23:36Familiar pathway or trap?
  • 23:38Seven or more likely to record an
  • 23:40average 22 times higher than others,
  • 23:43and this held true at 17 times
  • 23:46higher amongst grade ones.
  • 23:47And So what type of mutation is
  • 23:50underlying or driving the meningioma
  • 23:52biology is associated with whether
  • 23:54or not the tumor will occur and
  • 23:57even when it will occur in that
  • 23:59some of these tumors with a KT1
  • 24:02mutations in the PI3 kinase signaling
  • 24:04pathway typically recurs sooner.
  • 24:07And this is 1 aspect of of the answer
  • 24:09to the puzzle as to why some grade one
  • 24:13meningioma is behave more aggressively,
  • 24:16and so here going back to our patient,
  • 24:18how could how could this have been
  • 24:20predicted in managed differently
  • 24:21the first time?
  • 24:22This is how and so this is an example
  • 24:24of our molecular analysis report
  • 24:26that we receive on every patient
  • 24:29we operate on at Yale.
  • 24:30And here the histological diagnosis of this
  • 24:33patient was actually a Grade 2 meningioma,
  • 24:36not a grade. And Angioma,
  • 24:38which was initially diagnosed in 2015.
  • 24:40So you might say, well,
  • 24:42maybe I transitioned from
  • 24:43a low grade to high grade.
  • 24:44The answer is no.
  • 24:46Looking at the molecular information,
  • 24:48there's an NF2 mutation and then based
  • 24:52on the chromosomal abnormalities
  • 24:54in the copy number alterations,
  • 24:57we can tell that this was one that
  • 25:00was denovo and had been a typical
  • 25:03meningioma but was misdiagnosed
  • 25:05histologically back in 2015.
  • 25:07And so, in our hands we would have
  • 25:09respected that tumor and likely
  • 25:11radiated the tumor up front after,
  • 25:13or at least kept a very close follow up.
  • 25:16Another patient with another one
  • 25:18of these grade one meningiomas.
  • 25:20This was a patient that was
  • 25:22operated on by someone else.
  • 25:24Had this large tumor surgeon
  • 25:25left a small residual to preserve
  • 25:27endocrine function and just six
  • 25:29months later you can see the growth.
  • 25:32That's not growth that you would
  • 25:34expect with a Grade 1 meningioma,
  • 25:36and so then the patient underwent radiation
  • 25:38and then continued to have growth.
  • 25:41This is actually not the most
  • 25:42recent follow up.
  • 25:43I'm sorry for that error.
  • 25:44She's had more growth, more recurrence.
  • 25:48I've operated on her a couple of times.
  • 25:49Since then she's had more radiation
  • 25:51and has been enrolled in clinical trials.
  • 25:54And here's her Histology
  • 25:56and molecular report,
  • 25:58so it still remains a grade one meningioma,
  • 26:01but you can see that a KT1 missense
  • 26:03mutation and based on our findings in
  • 26:06the neural oncology paper and here,
  • 26:07you see that these tumors
  • 26:09tend to occur earlier.
  • 26:11And the last patient example,
  • 26:14very complicated, patient with another grade,
  • 26:16one meningioma who underwent
  • 26:19surgery elsewhere a few times.
  • 26:21Radiation elsewhere a few times,
  • 26:24was enrolled in a clinical trial
  • 26:26with Priscilla Brosterhous at MGH.
  • 26:28She recurred.
  • 26:29This was her recurrence,
  • 26:31highly vascular tumor.
  • 26:32As you can see,
  • 26:33Priscilla center down here
  • 26:35to me for surgical resection.
  • 26:37We got a nice surgical resection,
  • 26:39and here's her genomics again that.
  • 26:41Act one mutation and so the point
  • 26:43being is that maximizing the surgical
  • 26:46resection is of course a huge part in
  • 26:49survival and progression free survival.
  • 26:52Getting a good tissue diagnosis
  • 26:54is incredibly important,
  • 26:55but really managing patients as
  • 26:57we do in most academic centers do
  • 27:00based on the molecular diagnosis and
  • 27:02not just not relying on Histology,
  • 27:04is incredibly important.
  • 27:07We hope that our patients find it
  • 27:09easy to navigate through the system
  • 27:11through our multi disciplines and
  • 27:13of course through our health system
  • 27:15including Bruce and and others who
  • 27:17are located in Greenwich and other
  • 27:19satellite places throughout the state.
  • 27:21We're so thankful to the Lovemark
  • 27:23Foundation and the Connecticut
  • 27:25brain tumor alliance to provide
  • 27:26support to our patients,
  • 27:27and I am incredibly thankful to these
  • 27:30ladies and men who I work with every day.
  • 27:32Jillian and Marcy,
  • 27:33who are nurse practitioners in
  • 27:35our brain tumor surgery program.
  • 27:37Kelly and Marsala,
  • 27:38who are nurse coordinators
  • 27:40Larry and the other staff who work in the
  • 27:43operating room who assist me every day,
  • 27:45my clinical research fellow Sagar
  • 27:46Shari and and a bunch of other people,
  • 27:49who unfortunately aren't on this
  • 27:51in this picture, and Neil and Mary
  • 27:53and I them my clinical fellow,
  • 27:55so thank you once again for listening.
  • 27:57Thank you to Doctor Barris for
  • 28:00her generosity and her friendship.
  • 28:03I will turn this over to Zach and
  • 28:05I guess we'll take questions at
  • 28:08the end and I'll stop sharing.
  • 28:10So Zach Corbin. A friend, a colleague.
  • 28:16A wonderful neuro oncologist,
  • 28:18and I'm really exciting.
  • 28:19Because excited,
  • 28:20because he's going to speak to you now
  • 28:22about emerging therapies for brain tumors.
  • 28:24And he's also going to talk about
  • 28:25some of his exciting research and and
  • 28:27work that he's doing with imaging.
  • 28:33Perfect thank you so much for
  • 28:36that wonderful introduction and
  • 28:38talk and what a lovely dovetail.
  • 28:40I wish if I had actually
  • 28:42been able to modify my title,
  • 28:44I would say emerging classifications
  • 28:46and therapies of brain tumors
  • 28:47because a lot of what I'm going
  • 28:49to talk about is exactly that.
  • 28:51The really we have changed recently.
  • 28:53The way we're thinking
  • 28:55about primary brain tumors.
  • 28:56So yeah, so I'm Zachary Corbin.
  • 28:58I'm one of the neuro oncologists
  • 29:00based at Smilo and I look forward to
  • 29:02talking to you for a few minutes.
  • 29:03Today and thank you for having me so.
  • 29:07I'd like to start by saying that I
  • 29:09do have a a disclosure that I will be
  • 29:12discussing off label use of procarbazine,
  • 29:14otherwise no relevant disclosures.
  • 29:16I'm going to talk about my
  • 29:18the structure of my talk.
  • 29:20We talk about glioma and meningioma
  • 29:23very similarly to doctor Moliterno
  • 29:25talk about the classification that
  • 29:27we have begun to use very recently.
  • 29:30Based on the 2021 WHO and then
  • 29:33standards of care,
  • 29:35including some relatively new ASCO
  • 29:38snow guidelines that can help
  • 29:41clinicians make the decision about
  • 29:42patients who are not able to or choose
  • 29:45not to enroll in clinical trials.
  • 29:47And then,
  • 29:48of course,
  • 29:48I want to discuss about clinical trials.
  • 29:50That we have available at Yale,
  • 29:52and the approaches that they may offer.
  • 29:55Then I'll switch to meningioma and
  • 29:56doctor Moliterno has covered a lot of the
  • 29:59standard of care have been in GMs already,
  • 30:00but I'll summarize,
  • 30:01and then I'll discuss a couple of
  • 30:04clinical trials we have available.
  • 30:06And absolutely at the end.
  • 30:07I look forward to.
  • 30:08Sharing some research that I'm
  • 30:11doing and some observational studies
  • 30:12that are available to patients
  • 30:14who are seen at her Cancer Center.
  • 30:16So without further ado,
  • 30:17I'd like to talk a little bit about glioma,
  • 30:21and I'm sure most people watching this
  • 30:25talk are familiar with the disease,
  • 30:27but some I think underappreciated
  • 30:30facts include that it is the second
  • 30:32most common type of primary brain tumor.
  • 30:34It has a higher burden than I
  • 30:36think most realized that 19,000.
  • 30:38New diagnosis in the US.
  • 30:40The most recent count annually and over
  • 30:4412,000 of these patients have glioblastomas,
  • 30:47and despite even even more than what
  • 30:50doctor Moliterno has had a chance to cover.
  • 30:54What we do clinically and research.
  • 30:56Despite all of this and for decades.
  • 30:59Less than excuse me,
  • 31:00just a little bit over one in 20
  • 31:03patients at five years remain alive.
  • 31:05The most recent count is 7.2% and
  • 31:07I'm going to end by saying the silver
  • 31:09lining is that count is going up
  • 31:11and so we are making gains and we
  • 31:14are continuing on our quest as I'm
  • 31:16sure most watching this talk are.
  • 31:20Pathologically or histopathologically,
  • 31:21and hopefully you guys can see my point here,
  • 31:24feel blastoma appears like this.
  • 31:25You can see lots of areas in the
  • 31:28tumor microscopically that have
  • 31:29different shapes and nuclei.
  • 31:31You can see necrosis.
  • 31:32You can see pseudo palisading areas,
  • 31:34which is what this call where you
  • 31:36can see the
  • 31:37sheets kind of dive into the necrosis and
  • 31:40you can see areas of vascular proliferation.
  • 31:43Another thing that I always like
  • 31:45to talk about is how important
  • 31:47publicly this disease is.
  • 31:49So these three men all died of glioblastoma
  • 31:52or high grade glioma and for those of you
  • 31:56who don't know who one of these people are,
  • 31:59I'm sure that most people know all of them.
  • 32:01This is Ted Kennedy,
  • 32:03he was President John F.
  • 32:05Kennedy's brother.
  • 32:05This is Beau Biden,
  • 32:07President Biden son and this is John
  • 32:10McCain's most recent example of this picture,
  • 32:12but I think.
  • 32:13That this really goes to show how,
  • 32:15although a rare disease,
  • 32:17officially an extremely important
  • 32:19disease in many other ways
  • 32:21than we might initially think.
  • 32:23So as I said,
  • 32:24I'm going to talk about the way we
  • 32:26classify gliomas in the context of the 2021,
  • 32:29WHO classification of tumors
  • 32:31of the central nervous system.
  • 32:33This is actually very recent,
  • 32:35and last time I checked,
  • 32:36we still didn't have the because
  • 32:38of COVID related printing delays.
  • 32:40We still didn't have the actual
  • 32:42final results to review ourselves,
  • 32:44but we have this preview and I'm
  • 32:46going to summarize it for you today.
  • 32:48So the preview I think is
  • 32:50best summarized in a diagram,
  • 32:52and you can see starting here that.
  • 32:54Really,
  • 32:55we start where we used to be
  • 32:57with histopathology and then as
  • 32:59doctor Moliterno was discussing.
  • 33:01The answer is largely now related
  • 33:04to molecular findings and the
  • 33:06first dichotomy is the IDH
  • 33:09isocitrate dehydrogenase genes.
  • 33:12So a tumor that expresses an IDH mutation
  • 33:15is a tumor for which we understand
  • 33:18the patient who has that tumor.
  • 33:20Their outcomes are better and the
  • 33:23tumor grows less and then a dichotomy.
  • 33:25After Idhe mutation is whether or not that
  • 33:28tumor expresses another genetic change,
  • 33:30it's called 1P19.
  • 33:31Q code deletion and so an IDH mutant
  • 33:341P19 Q code deleted tumor almost
  • 33:37no matter what it appears under.
  • 33:39The microscope isn't all the good enough,
  • 33:41Ryoma and I'll get into gliomas
  • 33:44are actually graded histologically,
  • 33:46as are the other tumors.
  • 33:47So that is where we can use
  • 33:50Histology and molecular features
  • 33:51so WHO grade two and WHO grade 3
  • 33:53all the good and agree on this.
  • 33:56And then if actually there is no one P.
  • 33:5819 Q code deletion,
  • 34:00you can see that there are
  • 34:02astrocytomas which are IH mutant.
  • 34:05These are kind of cousins of the stoma,
  • 34:08but actually even a Grade 4
  • 34:11astrocytoma that is an NIH mutant
  • 34:14is in this classification,
  • 34:16not considered a glioblastoma.
  • 34:17That is a big change we used to call
  • 34:20patients who had tumors that were WHO
  • 34:23grade for histologically a glioblastoma.
  • 34:25If they were astrocytic,
  • 34:27whether or not they had ID communications.
  • 34:30So you can see that this whole
  • 34:32category of tumors is quite different
  • 34:34because it has different molecular
  • 34:36features and also different clinical
  • 34:38outcomes and so moving right.
  • 34:40Unfortunately these tumors grow more
  • 34:42aggressively in patients who have
  • 34:44them have generally shorter outcomes,
  • 34:46although with aggressive treatments,
  • 34:47we're hoping that that also will
  • 34:49change. So if the patient does
  • 34:51not have an ID quotation we refer
  • 34:53to that as an IH wild type tumor.
  • 34:56And you can see that those characteristics
  • 34:58under the microscope I described before
  • 35:00can help describe a glioblastoma
  • 35:01which is also called glioblastoma idh,
  • 35:04wildtype CCNS, WHO grade four.
  • 35:07And then you can see that there are other
  • 35:10similar Leo Blastomas or similar gliomas.
  • 35:13Sorry that have a Grade 4 characteristic
  • 35:15and in general these are considered diffuse,
  • 35:18midline and diffuse hemispheric
  • 35:20gliomas with the midline glioma has
  • 35:23an H3K27 alteration so moving on.
  • 35:27The standard of care for glioblastoma
  • 35:30is still based on a study that was
  • 35:33actually old when I was a fellow,
  • 35:36which is the study protocol.
  • 35:37And you'll hear us discuss the study
  • 35:39protocol when we discuss management and
  • 35:41a couple things I want to highlight
  • 35:43on this slide is that the curves
  • 35:46despite aggressive treatment,
  • 35:47continue to go down,
  • 35:49but this is actually continues to be
  • 35:51the basis for which we treat many
  • 35:54patients and maybe motivation to
  • 35:56keep these curves.
  • 35:57Up for pursuing more clinical trials
  • 35:59and then the other thing I'd like to
  • 36:01show once again is that it's 2005.
  • 36:03So now 17 years old and we do
  • 36:06have additional advancements.
  • 36:09I'm not trying to say that we
  • 36:10have been frozen since 2005,
  • 36:11but it is remarkable to think
  • 36:14about how long we've been.
  • 36:16We've had these results so as I was saying,
  • 36:19I'd like to move forward just
  • 36:20because guidelines not just
  • 36:21have the tree clear blastoma,
  • 36:23but all gliomas and so this is
  • 36:25the American Society for clinical.
  • 36:27Ecology ASCO and the Society
  • 36:30for Neuro Oncology.
  • 36:312 American organizations to manage
  • 36:33Neuro ONC and they issued combined
  • 36:35recommendations for the different
  • 36:36categories of tumor and so I
  • 36:39thought I would just go through the
  • 36:41different categories one by one.
  • 36:43I mentioned all of these in the diagram
  • 36:46that I discussed before all go into gliomas,
  • 36:49Deputy O grade one.
  • 36:51I should I should say,
  • 36:53but you guys already know.
  • 36:55The maximum safe for section and when
  • 36:58possible is the start to management
  • 37:00of almost all of these tumors.
  • 37:02But once we get to maximum safer section
  • 37:05and have the best pathologic evidence,
  • 37:08observation is possible,
  • 37:10which means we monitor closely with
  • 37:12scans and these patients low risk
  • 37:15disease has specific features,
  • 37:16but if a patient is over 40 or
  • 37:19a patient has remaining tumor,
  • 37:21they are not considered low risk,
  • 37:23and so we proceed with radiation
  • 37:25combined with.
  • 37:26Either procarbazine Lomustine
  • 37:27and Chris Vincristine,
  • 37:28which you'll hear me discuss for
  • 37:31here on as PCV or team ITAR or TMZ.
  • 37:36Temodar is emphasized as an option if
  • 37:40there's concerns for someone tolerating PCV.
  • 37:44However,
  • 37:45I would say that there are also
  • 37:48oncologists that actually favor temodar
  • 37:51because the evidence is also strong
  • 37:54for temodar in that the stoop protocol,
  • 37:58for example,
  • 37:58is a more treated and more
  • 38:00aggressive tumor with team donor,
  • 38:02and this is an open question
  • 38:04which we are actually
  • 38:05trying to address at Yale.
  • 38:07Olive good good inglima
  • 38:08is Newton grade three.
  • 38:10We do not have any ability to monitor these,
  • 38:13whether or not the tumor is entirely
  • 38:15or we would not recommend.
  • 38:16I should say, monitoring these.
  • 38:17Whether or not the tumor is entirely removed,
  • 38:19we would proceed with radiation
  • 38:22combined with PCV or possibly all
  • 38:25using team radar as an alternative.
  • 38:28I astrocytomas IH mutants
  • 38:30that are WHO grade 2.
  • 38:33For those of you who are familiar
  • 38:34with the old classification,
  • 38:35these used to be called diffuse astrocytomas.
  • 38:38These are possible to observe,
  • 38:40once again with good characteristics.
  • 38:43Some some would argue that they
  • 38:45should be treated with radiation
  • 38:47followed by adjuvant chemotherapy,
  • 38:49and in this case,
  • 38:50I think the field generally
  • 38:52prefers temodar over PCV,
  • 38:54but the guidelines offer
  • 38:55a choice between both.
  • 38:57In case it's not clear why one
  • 38:59would prefer team at our over PCV,
  • 39:01PCV is a is a.
  • 39:03Is a chemotherapy regimen that
  • 39:06involves multiple chemotherapies that
  • 39:08each involve different side effects
  • 39:10that can be difficult to tolerate,
  • 39:11and they can also limit the ability for
  • 39:15the patient to take the whole regimen.
  • 39:17Temodar is less prone to those limitations.
  • 39:22So moving forward,
  • 39:24astrocytoma ID student debt charade 3.
  • 39:27This is a tumor that there is
  • 39:29some debate about how to treat,
  • 39:30but radiation with adjuvant temodar
  • 39:33is the recommended method and the
  • 39:35guidelines and then maybe there's more
  • 39:38debate with IDH mutant tumors WHO grade 4.
  • 39:41Once again,
  • 39:41these tumors used to be called gliomas,
  • 39:43tumors that we now refer
  • 39:45to them as astrocytoma,
  • 39:46IDH, Newton.
  • 39:47So radiation with adjuvant temodar is
  • 39:51is offered or treatment for the study
  • 39:56protocol as a glioblastoma is treated.
  • 39:59So moving forward glioblastoma.
  • 40:01Sorry IH wild type tumors.
  • 40:04Astrocytoma IH well typed either
  • 40:06grades two or three are generally
  • 40:08recommended to be treated as the oldest.
  • 40:11Thomas Glioblastoma is our idea 12
  • 40:15type who grade 4 so those tumors.
  • 40:18We recommend treating either with the
  • 40:21study protocol or possibly additional
  • 40:23changes in a subset of patients,
  • 40:26so the study protocol,
  • 40:27which I've now mentioned
  • 40:28probably 8 times by name,
  • 40:29but haven't actually told you what it is.
  • 40:31This is where you do radiation
  • 40:33combined with Team Adar.
  • 40:34At the same time,
  • 40:36that's called Chemoradiotherapy
  • 40:37with temodar and then patients
  • 40:39receive 6 cycles or six months
  • 40:41of team that are thereafter.
  • 40:43You patients are certainly are physicians
  • 40:46and patients together are certainly
  • 40:48allowed to receive more chemotherapy.
  • 40:50Up to 12 is is still standard,
  • 40:52but most of the field is considering
  • 40:55moving back to six cycles at this point.
  • 40:58Certainly in some patients.
  • 41:00And alternating electric fields are delivered
  • 41:03by a device called the Optune device,
  • 41:06and this may be added either
  • 41:08actually at diagnosis,
  • 41:10which is what this recommendation is about,
  • 41:12or have recurrence actually
  • 41:13in a subset of patients.
  • 41:15These patients are patients who may
  • 41:17be elderly or may have some reasons
  • 41:19why we don't think they could
  • 41:20tolerate what it ends up being.
  • 41:22Quite an intense therapy we can proceed
  • 41:25with hypofractionated radiation with
  • 41:27concurrent and adjuvant Thermidor
  • 41:28hypofractionated is only three weeks long.
  • 41:31As opposed to six weeks long,
  • 41:33but I'm not going to get into
  • 41:34any more details about radiation
  • 41:36because Doctor Mcgibbon is the
  • 41:37expert and we'll be speaking later.
  • 41:39And then alternatively,
  • 41:40if we think that team radar may
  • 41:42not be useful because of other
  • 41:43molecular features which are
  • 41:45outside of the scope of this talk,
  • 41:46you could you could do
  • 41:48hypofractionated radiation alone.
  • 41:49You could do team at our monotherapy
  • 41:51alone and then of course there are
  • 41:53some patients that either choose
  • 41:54or may not tolerate any treatment
  • 41:56and supportive care is an option
  • 41:59to proceed with with glioblastoma.
  • 42:01So on a brighter note,
  • 42:02I'd like to talk about clinical
  • 42:04trials that we offer.
  • 42:05So one thing to talk about clinical
  • 42:07trials is that these trials often
  • 42:09don't replace the standard of
  • 42:11care we get that question a lot.
  • 42:13Often they will augment the standard of care,
  • 42:15or they ask questions about the
  • 42:17standard of care and the other thing
  • 42:19to note about clinical trials is
  • 42:20that a clinical trial that I would
  • 42:22recommend to a patient is going
  • 42:24to be one that exhibits equipoise.
  • 42:26This is a true experiment where
  • 42:28we're trying to answer something we
  • 42:29don't know the answer to, and so.
  • 42:32I mentioned the the question that this
  • 42:34trial is trying to address already,
  • 42:37so we have a trial for patients who
  • 42:40have oligodendrogliomas WHO grade
  • 42:41two who have high risk disease.
  • 42:43Once again,
  • 42:44they're over 40 or they have a
  • 42:47residual tumor or grade three.
  • 42:49They can enroll in a trial where
  • 42:51we are actually proceeding with
  • 42:52adjuvant radiation that's either
  • 42:53combined with temodar or they proceed
  • 42:55with radiation followed by PCP.
  • 42:57Because once again we have this
  • 42:58question where we don't know what
  • 43:00is better and all the good and.
  • 43:01Family and patients who have
  • 43:02all the good nucleonics.
  • 43:04We have more trials in patients
  • 43:06who have leonas demo.
  • 43:07So we have a Phase 01 trial which
  • 43:09is an early phase trial where we're
  • 43:12testing an immunotherapy regimen that
  • 43:14targets a type of checkpoint that's
  • 43:17called TIGIT that is used in addition
  • 43:20to or possibly alternating with,
  • 43:22the PD1 checkpoint,
  • 43:23which is a more famous checkpoint
  • 43:25that others may have heard of.
  • 43:26Drugs like pembrolizumab and nivolumab
  • 43:29target the PD one checkpoint,
  • 43:31we have a phase one trial of
  • 43:33a drug called FB PMT,
  • 43:35which is targeting cancer cell signaling.
  • 43:38And that is for patients who have
  • 43:40glioblastoma appearance or when the
  • 43:42tumor is growing back as doctor
  • 43:44Moliterno showed in multiple of the cases.
  • 43:46And then we have a trial that's really
  • 43:48complex and really kind of marvelous.
  • 43:50That's called the GBM agile trial.
  • 43:52In this trial was designed to exist
  • 43:54for a long time at a brain tumor
  • 43:56center like Yale and allow us to
  • 43:58sub installed agile because we're
  • 44:00able to sub in drugs that may be
  • 44:02exciting without having to close
  • 44:03the trial and open a
  • 44:05new trial. And so we have multiple
  • 44:07arms in this trial, so patients can
  • 44:09receive multiple types of therapies.
  • 44:11And also the trial allows
  • 44:13for enrollment of patients in
  • 44:14different phases of their disease.
  • 44:16So there are GBM agile arms where
  • 44:18patients can enroll at diagnosis and
  • 44:21where patients can enroll at recurrence.
  • 44:23So it's complex to describe,
  • 44:26but really an amazing thing
  • 44:28and pretty advanced.
  • 44:29A pretty remarkable advance.
  • 44:30I think in clinical trial design
  • 44:32and it's a privilege to be able to
  • 44:35offer patients the agents that are
  • 44:37being tested in GBM agile and they
  • 44:39will continue to change over time.
  • 44:41We also have a phase three,
  • 44:42double blind placebo controlled
  • 44:44trial where we are adding.
  • 44:46As I said,
  • 44:48we often add adding a experimental agent
  • 44:51called Enza Star in to the street protocol.
  • 44:54So to shift gears now.
  • 44:57So I'm going to talk about meningioma
  • 44:59briefly and then some trials.
  • 45:00We have.
  • 45:01Meningioma meningioma is actually the
  • 45:03most common type of primary brain tumor.
  • 45:06This annual incidence is around 35,000,
  • 45:09which I also think is remarkable and
  • 45:11as doctor Moliterno covered many
  • 45:13patients who have meningioma are
  • 45:15patients who have benign meningiomas,
  • 45:18although I prefer to call them
  • 45:20meningioma dibujo grade one.
  • 45:21This will be labeled them pathologically.
  • 45:24That's about 80%,
  • 45:25and the overall survival of these
  • 45:27tumors is difficult to categorize
  • 45:29and has been reported in different
  • 45:31ways over multiple sources.
  • 45:32But I'm giving you summaries here so
  • 45:35patients who have who Grade 1 tumors.
  • 45:37Certainly live over 10 years
  • 45:38and they may live longer.
  • 45:40Patients often don't even need
  • 45:42surgery with these tumors,
  • 45:43and so we don't actually really know the
  • 45:45true burden of WHO grade one minute GMs.
  • 45:48But about.
  • 45:5018% or about 1/5 of patients have more
  • 45:52aggressive tumors that Doctor Mall
  • 45:54Turner has lots of experience with
  • 45:56called atypical meningiomas Debuchy
  • 45:57grade two and there's variable reports
  • 46:00about how long patients in general
  • 46:02live at this point with these tumors.
  • 46:04But we think about 80 to 100% of
  • 46:06patients remain alive at five years,
  • 46:08which is good.
  • 46:10Unfortunately, WHO grade 3 tumors,
  • 46:12also called in plastic and angiomas I guess.
  • 46:15Fortunately,
  • 46:15they're quite rare.
  • 46:17Approximately 2% or so patients have
  • 46:19these tumors who have meningioma,
  • 46:21but the median overall survival is
  • 46:23much more dramatically lower that
  • 46:25measured in a couple years two to three.
  • 46:28So standard of care with meningioma,
  • 46:30so we have to discuss something
  • 46:32that we don't generally talk about
  • 46:34in gliomas which is presumed
  • 46:36meningioma is a whole category
  • 46:37of patients who have a scan.
  • 46:39I think some of the times they get
  • 46:40very scared they come to see either
  • 46:42in their surgeon neurologist and we
  • 46:43may tell them this tumor may not
  • 46:45cause you difficulty with it looks
  • 46:46to us like it may be a WHO Grade 1
  • 46:50meningioma and we can monitor it.
  • 46:51So we call those presumed meningioma.
  • 46:53They're often asymptomatic,
  • 46:54and imaging surveillance may be appropriate,
  • 46:57but once it becomes.
  • 46:58Medical jobs than they do,
  • 46:59and then I might prefer that
  • 47:01patient to doctor Moliterno.
  • 47:02Then we proceed with maximum
  • 47:04security just the same way,
  • 47:05with glioma and surgery or radiation.
  • 47:09If surgery is not possible or
  • 47:11the options for these presumed
  • 47:13or asymptomatic managements.
  • 47:14And really as I was saying
  • 47:16with with all grades one,
  • 47:17two and three we start otherwise
  • 47:20with maximal surgical resection.
  • 47:21Meningioma,
  • 47:22WHO grade one specifically if it has
  • 47:24recurrent disease we consider radiation
  • 47:27and then we get into controversy.
  • 47:29Which we are having also a
  • 47:31clinical trial at Yale to address.
  • 47:33So the controversy is what to do with
  • 47:35someone who has an atypical meningioma.
  • 47:36W2 grade two that has had a gross total
  • 47:39resection as doctor Moliterno showed.
  • 47:41In a case.
  • 47:42These do recur, but not all the time,
  • 47:45and sometimes we think that
  • 47:46the radiation may not actually
  • 47:48benefit as much as it put causes.
  • 47:50Some patients harm,
  • 47:52so we we then proceed to more specific cases
  • 47:56where there is residual disease on the scan.
  • 47:59After a surgery and for those patients,
  • 48:02we often we do recommend radiation for
  • 48:05patients who have anaplastic meningioma,
  • 48:07or there's even less controversy
  • 48:08for those patients,
  • 48:09resection or otherwise.
  • 48:11We recommend radiation.
  • 48:13So the clinical trials that are
  • 48:15available in Ninja for WHO Grade
  • 48:172 after gross total receptions.
  • 48:19This controversy is addressed
  • 48:21by a phase three trial.
  • 48:23Whether it's randomized patients either
  • 48:25go on surveillance or we proceed with
  • 48:28radiation and we continue to monitor.
  • 48:31For patients who have either WHO grades one,
  • 48:34two, or three,
  • 48:35any of those grades,
  • 48:37if they have a specific target,
  • 48:40they are offered enrollment in what
  • 48:44is a multi arm trial as well that
  • 48:47currently has an AKT inhibitor
  • 48:49that's called Kappa Vasser tip,
  • 48:51where CDK inhibitor that's called
  • 48:54abemaciclib Bemis cycling is actually
  • 48:56currently an approved medication,
  • 48:58so it's interesting to be able
  • 49:00to to offer it in this trial.
  • 49:03So now I'm going to switch
  • 49:05gears and talk about.
  • 49:07One of my true loves which is measuring.
  • 49:11Metabolic disease and also metabolic
  • 49:13processes in primary brain tumors,
  • 49:15and I'd like to talk briefly about
  • 49:17what target you would do or what
  • 49:19metabolic change you would target.
  • 49:21You would measure,
  • 49:22so that is called the Warburg effect.
  • 49:25The Warburg effect is really a
  • 49:28biochemical principle, and really briefly.
  • 49:29When any cell which is this is the,
  • 49:33this is the outside of the
  • 49:34cell in my diagram.
  • 49:34This is the inside of the cell,
  • 49:36cause glucose,
  • 49:36which most people are familiar with.
  • 49:38The each you get glucose,
  • 49:39glucose comes in and becomes a
  • 49:41certain molecule called pyruvate,
  • 49:43and then the body may process it either
  • 49:45through a process called oxidative
  • 49:47phosphorylation through a part of
  • 49:49the cell called the mitochondria,
  • 49:51which is the Semitic cartoon,
  • 49:53and then it may either and.
  • 49:55Then it evolves CO2 which
  • 49:57might be bicarbonate,
  • 49:58because bicarbonate and CO2 exist in water.
  • 50:00Which most of the inside of the cell is.
  • 50:02Alternatively,
  • 50:03pyruvate may become lactate,
  • 50:05but it actually does not
  • 50:07use oxygen in this case,
  • 50:08and that's called lysis.
  • 50:09So the Warburg effect defines the
  • 50:12fact that even in normal oxygen,
  • 50:15a tumor cell or tumor process
  • 50:18favors lactate and glycolysis,
  • 50:20and so that Warburg effect shifts tumor
  • 50:23Physiology in this diagram to the right.
  • 50:26And so to measure this difference
  • 50:28might help us with lots of
  • 50:30insights about how tumors work,
  • 50:32and I have two ways that I've
  • 50:35opened observational studies.
  • 50:36These are not trials,
  • 50:37we're actually just trying to
  • 50:39measure characteristics of the
  • 50:40tumors and not affect anyone's care.
  • 50:42But two ways we might measure
  • 50:44the Warburg effect.
  • 50:45This is called the Warburg index.
  • 50:47We take patients and offer
  • 50:49them a what's called an FDG or
  • 50:52floor deoxy glucose PET scan.
  • 50:54So FDG is a small dose of radioactivity
  • 50:56that also comes via the blood
  • 50:58comes into the cell and it's it's
  • 51:00phosphorylated or phosphorus is
  • 51:02added to FDG and it stays there
  • 51:04and we can actually observe it in
  • 51:06something called the scintillator.
  • 51:08Now the very observant ones would
  • 51:10say that we're only watching
  • 51:11one part of metabolism.
  • 51:13That's right,
  • 51:14so this is actually basically
  • 51:15total glucose metabolism.
  • 51:16This is a rough estimate of
  • 51:18oxidative phosphorylation,
  • 51:19so we use a different technique in
  • 51:21these patients as well, called Mrs.
  • 51:23Petrosky or spectroscopic imaging,
  • 51:25and we can detect the lactate,
  • 51:26and so we have the both sides,
  • 51:28lactate and FDG.
  • 51:29We give us the Warburg index.
  • 51:32This is a clinically available tool
  • 51:34and we're very excited to be able to
  • 51:36offer it to patients who are otherwise.
  • 51:38It's even care or brain tumor center.
  • 51:41And earlier,
  • 51:41but also very exciting and its
  • 51:44development process is called
  • 51:45deuterium metabolic imaging.
  • 51:47Deuterium metabolic imaging.
  • 51:48We use deuterated glucose that
  • 51:50patients can just drink the same
  • 51:51way you drink a soda or Gatorade,
  • 51:53and the glucose comes in and
  • 51:55becomes pyruvate.
  • 51:56It becomes lactate and it becomes
  • 51:59molecules called glutamate and glutamine.
  • 52:01The point is that in a marvelous way,
  • 52:03in this specific MRI scanner,
  • 52:05we can actually see lactate,
  • 52:08and we can see glutamine,
  • 52:09glutamine representing these two.
  • 52:12Processes directly,
  • 52:13and so we can see the Warburg index
  • 52:15shifting to the right and we call
  • 52:17this the Warburg effect once again.
  • 52:19And so here's a great example that
  • 52:21we were able to publish of a patient
  • 52:23of mine who had a brain tumor.
  • 52:25And this is actually an IDH wild type wheel.
  • 52:28Best drama and you can see that they
  • 52:30have a very large forberg effect,
  • 52:32so there's there's lots of
  • 52:34possibilities here about what we
  • 52:36might use this for patients who
  • 52:38have higher warburger effects.
  • 52:39We have a theory that and it
  • 52:41has been shown there.
  • 52:41Tumors are more aggressive and
  • 52:43can we actually walk the way the
  • 52:45Warburg effect might change over
  • 52:46the course of their treatment year,
  • 52:48either in radiation or chemotherapy?
  • 52:50Can we predict whether or not
  • 52:52someone might survive the way
  • 52:54the the patient with the tumor?
  • 52:55That doctor Moliterno showed,
  • 52:57we predict better survival or poorer
  • 53:00survival based on metabolic signatures.
  • 53:03So thank you guys so much for listening.
  • 53:05I want to acknowledge all of my current and
  • 53:09prior lab mates and they have done so well.
  • 53:13Two of them are already in medical
  • 53:15school and also my funding.
  • 53:16I received the Yci scholar word
  • 53:18as well as my collaborators R1,
  • 53:21and this is really a process both
  • 53:23clinical care for brain tumors as well
  • 53:25as clinical research for brain tumors
  • 53:28takes a village and not only doctor
  • 53:30Moliterno and the other neurosurgeons,
  • 53:32not only doctors bearing and Amuro
  • 53:35and Hafler and the other neurologists.
  • 53:38Of course my mentors from before the YCI,
  • 53:40my colleagues at MRC the Pet Center.
  • 53:43And of course, radiation oncology,
  • 53:45including Doctor Mcgibbon.
  • 53:46So thanks so much everyone,
  • 53:49and I will now stop sharing
  • 53:51so that everyone can.
  • 53:52Move forward,
  • 53:53I guess we'll take questions at the end.
  • 53:56Yeah, people can just throw questions
  • 53:58into question and answer or into the chat,
  • 54:01but that was really an excellent talk.
  • 54:02Zach. Thank you so much.
  • 54:04So next I just want to introduce
  • 54:06Doctor Bruce Mcgibbon who
  • 54:08is from Greenwich Hospital.
  • 54:09He is the medical director
  • 54:11there for radiation oncology.
  • 54:13Thank you so much.
  • 54:15Great talk so far.
  • 54:16I'm really pleased to be
  • 54:18invited to give this this talk.
  • 54:21Like Jim was mentioning,
  • 54:22I'm down at the Greenwich site,
  • 54:23previously at the Trumbull site and
  • 54:25it's just really great to be able
  • 54:28to collaborate with our experts
  • 54:30in New Haven and and extend care
  • 54:32down the state to really have
  • 54:34a broader outreach to to what
  • 54:36we can help patients with with
  • 54:38this type of collaborative care.
  • 54:40Let me share my screen here.
  • 54:46OK.
  • 54:51No.
  • 54:56Go back OK, so I'll be talking about the
  • 54:58role of radiation therapy in the treatment
  • 55:01of brain tumors and with a particular
  • 55:03focus on glioblastoma and meningioma,
  • 55:05I have no disclosures.
  • 55:09So where does radiation therapy fit in?
  • 55:11Uh, you've heard about it a little
  • 55:14bit this evening, but just briefly.
  • 55:16I would say for benign tumors,
  • 55:19sometimes radiation is given
  • 55:20in place of surgery.
  • 55:22If it's something quite small and
  • 55:24and really doesn't require surgery,
  • 55:25but more often given sometimes
  • 55:27as postoperative treatment
  • 55:28if the tumor is left behind,
  • 55:30or were some extra worried that it will
  • 55:34progress and then for malignant tumors.
  • 55:37That, like, uh,
  • 55:38we talk about glioblastoma and
  • 55:39the anaplastic tumors, and so on.
  • 55:41That doctor Cogan was doing such
  • 55:43a nice job of going through.
  • 55:45Sometimes we'll offer radiation
  • 55:46when there's only been a biopsy,
  • 55:48but more commonly as we heard a lot about.
  • 55:51We really love when a maximum safe
  • 55:53for section that can be done and
  • 55:55and the outcomes are so much better.
  • 55:57And, you know,
  • 55:58we really are hand in glove with all
  • 56:01the other experts from neurology,
  • 56:03you know,
  • 56:04surgery and the other folks
  • 56:05being mentioned on this on this.
  • 56:07Talk series.
  • 56:09The radiation most of the treatments are
  • 56:12done in what's called a linear accelerator,
  • 56:15which is what you see in the top left
  • 56:17corner here, and that is the cursor.
  • 56:19So the patient would lie on
  • 56:21the table like this.
  • 56:23Kind of zooming in.
  • 56:24There's usually a mask that's done
  • 56:25to help hold people.
  • 56:26Still,
  • 56:26it's not painful in any way you
  • 56:28can see and breathe through it,
  • 56:30but it helps to hold the head still.
  • 56:31So when we're delivering radiation with,
  • 56:34you know millimeter something,
  • 56:35submillimeter accuracy,
  • 56:36we're really delivering
  • 56:37exactly where we want,
  • 56:38and not a little to one side or the other.
  • 56:41The radiation comes out of
  • 56:42the head of the machine here,
  • 56:44and this this portion of machine can
  • 56:47rotate around so we can come at the
  • 56:50at the tumor from different angles.
  • 56:52In the head of the Machine is a really
  • 56:55nifty device called a multi leaf
  • 56:57collimator which is represented here.
  • 56:59Each is ignacy, their own like little slats,
  • 57:02and these are very thin leaves.
  • 57:03They're very tall,
  • 57:05but they're made of a tungsten alloy,
  • 57:08which is a really heavy metal.
  • 57:09And when patients often ask,
  • 57:11you know when I go to the dentist.
  • 57:12I I have a lead apron,
  • 57:14what do I get here and say,
  • 57:15well,
  • 57:15the lead apron is not going to
  • 57:16cut it for therapeutic radiation
  • 57:17or go straight through it,
  • 57:19but if you have a the equivalent
  • 57:20of lead apron which is several.
  • 57:22Inches thick in the head of the gene.
  • 57:24That's what's really giving the
  • 57:26protection and doing the shaping
  • 57:28of the radiation.
  • 57:29We also have something that's
  • 57:31been developed over the last.
  • 57:34I'd say 10 to 15 years and was
  • 57:35really hitting its stride now called
  • 57:37image guided radiation therapy.
  • 57:39So we do some planning scans
  • 57:41before radiation,
  • 57:42including a CAT scan and overlay
  • 57:44that as I'll show later and talk
  • 57:46with MRI studies and other studies
  • 57:48will help us to show where we want
  • 57:50to treat what we want to avoid,
  • 57:52and then when the patients come
  • 57:53for these daily treatments so
  • 57:55we can do imaging on the table.
  • 57:56So if you look here on the right,
  • 57:57the head of the machine here again
  • 57:59is where the ration comes out.
  • 58:00But these panels on the sides can do imaging,
  • 58:03so we can look in the head and say OK,
  • 58:04how does the skull align today
  • 58:07compared to yesterday compared to
  • 58:08when we did the planning scan and
  • 58:10so these images in the in the left
  • 58:12in the middle are representing
  • 58:14really a fusion or overlay between
  • 58:16a daily scan and a planning scan.
  • 58:21Just give one example here of a
  • 58:24glioblastoma this the patient presented
  • 58:26with headaches and some difficulties
  • 58:27with concentrating and the image showed
  • 58:30this large tumor on the left side.
  • 58:35I'll just go briefly through this.
  • 58:37It's already been discussed.
  • 58:38Very nice doctor Corbin, but you know,
  • 58:39for glioblastoma we're always looking
  • 58:40for that maximum safe resection.
  • 58:42We usually allow about 3:00 to 5:00 or
  • 58:44up to three to six weeks between surgery
  • 58:47and when we start the chemotherapy and
  • 58:50radiation and then to be followed by more
  • 58:53chemo and sometimes the Optune device.
  • 58:55When we're making decision about
  • 58:57what style of radiation uh, to use,
  • 58:59uh, we're looking at the the age,
  • 59:02the overall performance status,
  • 59:04other features like MGMT that was
  • 59:06mentioned a little bit before we're
  • 59:07looking to see if there any clinical
  • 59:10trials that are available to really try
  • 59:12to advance the field in that way as well,
  • 59:13and give patients you know the
  • 59:15best that's possible.
  • 59:16So we put all the together and see
  • 59:18which style reason we're going to do.
  • 59:19I would say the majority of the
  • 59:21time will use that stoop protocol
  • 59:23with 30 treatments that actually.
  • 59:25These are done Monday to Friday,
  • 59:27so it's a six week course.
  • 59:29It actually has two phases.
  • 59:30The 1st 23 treatments in the final seven
  • 59:32were the 1st 23 a little bit broader and
  • 59:34the final seven are a little bit smaller.
  • 59:36They called it a come down idea and that's
  • 59:39the most the most common one by far.
  • 59:42But we have what's called hypofractionated
  • 59:46treatments and those could be offered
  • 59:48in someone who is elderly and and
  • 59:51has some other performance issues
  • 59:53or there's a travel concern or.
  • 59:56You know things of that nature.
  • 59:57We're trying to to be creative,
  • 59:59and how we're going to deliver
  • 01:00:00the treatment and and you know
  • 01:00:03balance side effects with with
  • 01:00:05treatment intensity and intent.
  • 01:00:07So in the hyperfractionated realm,
  • 01:00:08the one that we use the most
  • 01:00:10is a 15 treatment course.
  • 01:00:12But we have actually data for
  • 01:00:15five and and 10 treatments.
  • 01:00:17Usually for going all the way down to five.
  • 01:00:19Those are pretty intensive,
  • 01:00:20so that's usually somewhere
  • 01:00:21we're not doing a chemotherapy.
  • 01:00:23And I would say probably the same
  • 01:00:24with the 10, but 15 can be done.
  • 01:00:26Throughout chemo
  • 01:00:30so going back to to the case,
  • 01:00:31we have the square button where
  • 01:00:33now things have been removed.
  • 01:00:35We get a postoperative MRI to assess
  • 01:00:38what that looks like now and and
  • 01:00:40then we get into the planning phase.
  • 01:00:42So what we'll do is we'll take
  • 01:00:46where things were before surgery,
  • 01:00:47where they are after surgery and do
  • 01:00:50some drawings which are represented
  • 01:00:51by this kind of teal color,
  • 01:00:53cyan color and the purplish pink color,
  • 01:00:56and we're trying to to really dial in.
  • 01:00:59What we need to treat and this could involve,
  • 01:01:01uh, you know,
  • 01:01:02collaboration with the surgeon as well.
  • 01:01:04If we're not sure about you know an
  • 01:01:06area talking to the radiologists
  • 01:01:07we're really dialing in what?
  • 01:01:09What's at risk here and creating
  • 01:01:11a margin around that to account
  • 01:01:13for any microscopic extension
  • 01:01:15that could have happened?
  • 01:01:16There's a very intensive design process
  • 01:01:19where we work with our physics crew,
  • 01:01:21typically between the time that we got
  • 01:01:23our planning caps going to make that mask,
  • 01:01:24and when we start treatments about one week,
  • 01:01:27sometimes up to a week and a
  • 01:01:28half and some more complicated.
  • 01:01:29Days and these images on the left are
  • 01:01:32representing kind of vaguely make
  • 01:01:35out that there's also a person's
  • 01:01:37head that's represented in this
  • 01:01:39treatment planning software.
  • 01:01:40And then again that this kind of
  • 01:01:42pink and bluish colors are present.
  • 01:01:43We're trying to treat and usually
  • 01:01:45these things are done in arcs,
  • 01:01:47so this picture on on the bottom is
  • 01:01:49trying to represent how the machine
  • 01:01:51is going to move around the head.
  • 01:01:52So at each we can play with different things.
  • 01:01:55We can move the angle of the table to
  • 01:01:57create a different angle of attack.
  • 01:01:58We can.
  • 01:01:59Move the gantry or the head of the
  • 01:02:01machine around and at every position.
  • 01:02:03We can vary the intensity of the
  • 01:02:04beam and the shape of the beam,
  • 01:02:06and ultimately that allows us to create
  • 01:02:08what we call a dose distribution,
  • 01:02:10which is seeing here where we are
  • 01:02:12trying to conform the the higher
  • 01:02:14dose region of the radiation to
  • 01:02:16what we're trying to treat and then
  • 01:02:18have it drop off away.
  • 01:02:19So in this case on the right we're trying to.
  • 01:02:23These images are done as if you're
  • 01:02:24looking at someone from their
  • 01:02:25feet towards their head,
  • 01:02:26so this this kind of right side of the
  • 01:02:28image is actually the left side of the body.
  • 01:02:30And vice versa.
  • 01:02:31So in this case we're really
  • 01:02:32trying to avoid radiation dose,
  • 01:02:34especially going to the right
  • 01:02:36side of the brain.
  • 01:02:38We go through an intensive process
  • 01:02:40where we when we design the fields,
  • 01:02:41we get this complicated graph called
  • 01:02:44a dose volume histogram where every
  • 01:02:46color here represents a different
  • 01:02:48structure that we're trying to
  • 01:02:50either treat or avoid,
  • 01:02:51and so there's this iterative process
  • 01:02:53with the physics crews saying OK,
  • 01:02:54this plan was good or no.
  • 01:02:56We need to.
  • 01:02:56We need to shape the doses a little
  • 01:02:58bit more to stay off the brain stem.
  • 01:02:59We're off the copay or whatever it might be.
  • 01:03:01So we're we look at these and
  • 01:03:04and ultimately sign off on one
  • 01:03:06that looks like the best balance.
  • 01:03:08I'm moving to meningioma is an answer
  • 01:03:10for real great statement from the the
  • 01:03:13National Comprehensive Cancer Network
  • 01:03:14saying just really hear treatment
  • 01:03:16selection should be based on assessment
  • 01:03:18of a variety of interrelated factors,
  • 01:03:20including patient features,
  • 01:03:21tumor features,
  • 01:03:22potential for causing their logic,
  • 01:03:24consequences of untreated presence
  • 01:03:26and severity of symptoms and
  • 01:03:28treatment related factors,
  • 01:03:29and I'll skip the bond multidisciplinary
  • 01:03:31input for treatment planning is recommended
  • 01:03:33and this is where I feel so blessed to be.
  • 01:03:35You know, part of this yellow
  • 01:03:37network is really having these.
  • 01:03:38Super skilled trusted colleagues where
  • 01:03:40we have these weekly conferences and
  • 01:03:43we can call each other anytime and get
  • 01:03:45advice on a case or have someone seen
  • 01:03:47and it's just really critical to have that.
  • 01:03:51And it's nice to see it
  • 01:03:53represented as as the you know,
  • 01:03:55the goal according to national
  • 01:03:57guidelines as well.
  • 01:03:58So meningiomas again touched on
  • 01:03:59a lot better detail and more
  • 01:04:01thorough detail of Doctor Corbin,
  • 01:04:02but just it's kind of a very quick overview.
  • 01:04:06Again, sometimes we can do just observation.
  • 01:04:08If these are small grade one tumors,
  • 01:04:11but the game more advanced than
  • 01:04:13we typically would do surgery.
  • 01:04:15And if it's a grade one,
  • 01:04:16it's usually just observation
  • 01:04:17or sometimes radiation.
  • 01:04:19If there is a further issue that we
  • 01:04:21should be considering grade two, we,
  • 01:04:23let's say most often do radiation,
  • 01:04:25especially if there is a little
  • 01:04:27tumor left behind and for grade
  • 01:04:28through we definitely.
  • 01:04:29Offer radiation radiation.
  • 01:04:31This case is a little
  • 01:04:33shorter than glioblastoma,
  • 01:04:35it's it can be up to 30 treatments
  • 01:04:37like wheel, bustamonte,
  • 01:04:38sometimes a little less,
  • 01:04:39but the dose per day is a little bit lower.
  • 01:04:42And it's usually done as Monday
  • 01:04:44to Friday course sometimes,
  • 01:04:46especially if it's being done for a
  • 01:04:49very small tumor and it's lower grade.
  • 01:04:50We can do what's called
  • 01:04:52stereotactic radiosurgery,
  • 01:04:53where it's only one treatment
  • 01:04:54or up to five treatments.
  • 01:04:56But I'd say a lot of what we do is
  • 01:04:58the is the multi treatment option
  • 01:05:00and again I think that that just a
  • 01:05:02short presentation case presentation
  • 01:05:03is really helpful.
  • 01:05:04So this was a patient who presented
  • 01:05:07with Double Vision followed by
  • 01:05:09a right I decreased vision and.
  • 01:05:11You can see in the sand with the
  • 01:05:13red arrow there's something that
  • 01:05:15really doesn't belong there,
  • 01:05:17and if you track if you look here,
  • 01:05:18here's the eyeball and you see
  • 01:05:19this darker Gray coming back.
  • 01:05:21That's the optic nerve bringing
  • 01:05:23the visual information coming back.
  • 01:05:25So this tumor is really not only near
  • 01:05:27some really important blood vessels,
  • 01:05:29but is also near the Super important nerve.
  • 01:05:32So what? What to do?
  • 01:05:35Radiation alone is really not
  • 01:05:37gonna be her best option.
  • 01:05:39Uh,
  • 01:05:40radiation is excellent.
  • 01:05:41I'd say it's stopping millenniums
  • 01:05:43from growing further and can
  • 01:05:45make them slowly rest at least
  • 01:05:47sometimes give enough time,
  • 01:05:49but it's really not going
  • 01:05:51to create a rapid shrinkage.
  • 01:05:52It's not what we want someone's having
  • 01:05:54these kind of symptoms like double vision,
  • 01:05:55things we need. We need something.
  • 01:05:59More quickly effective,
  • 01:06:00and that's really comes down to surgery,
  • 01:06:02so this late underwent a right sided
  • 01:06:05craniotomy with Doctor Moliterno.
  • 01:06:08And because of that location there next
  • 01:06:10it was called the cavernous science or
  • 01:06:12some of the special blood vessels are.
  • 01:06:14It's really not possible to fully remove
  • 01:06:16the tumor, but a lot of it was removed.
  • 01:06:18It turned out to be a WHO grade one
  • 01:06:20and she had a great great response.
  • 01:06:23Revision came back to 2020 and had,
  • 01:06:26I would say,
  • 01:06:27a near resolution of the double vision.
  • 01:06:29But ultimately fully resolved, so we
  • 01:06:32got a postoperative MRI and as expected,
  • 01:06:35there was a little bit of of residual,
  • 01:06:37but much, much better as reflected
  • 01:06:39by her symptoms as well.
  • 01:06:40So you see the post op.
  • 01:06:42Sorry pre op on the left
  • 01:06:43and postop on the right.
  • 01:06:45And of course we don't want this growing
  • 01:06:48back and so we offered radiation.
  • 01:06:50Similar idea in terms of the mask and so on.
  • 01:06:52Using arcs again here working
  • 01:06:54with the physics crew to design
  • 01:06:57A set of radiation fields.
  • 01:06:59If you look behind here,
  • 01:07:00this is where the brain stem is,
  • 01:07:02so we're trying to stay off
  • 01:07:03that and off the eyeball,
  • 01:07:04so we're able to create this really.
  • 01:07:06As you say,
  • 01:07:07conformal radiation technique and the
  • 01:07:10combination of the surgery and then
  • 01:07:13the radiation was able to rib really
  • 01:07:16permanently control this tiller.
  • 01:07:20Just a quick also shout out to to my
  • 01:07:22colleagues and and doctor Bindra here
  • 01:07:24just to just to further emphasize what
  • 01:07:26Dr Milton and Doctor Corbin off said.
  • 01:07:28You know,
  • 01:07:29there's there's really great and and
  • 01:07:31super detailed work that's going on with
  • 01:07:33all these different mutations and you know,
  • 01:07:35adults and the kids,
  • 01:07:36and there's just a lot of work
  • 01:07:38to be done and it's just really,
  • 01:07:40really impressive.
  • 01:07:40This is one one trial here,
  • 01:07:43working on with the million gliomas and
  • 01:07:46the Doctor Bindra had shared with me just.
  • 01:07:49Look through and then another one
  • 01:07:51looking at adolescence and young
  • 01:07:53adults and other tricky glioma case
  • 01:07:55where there's more work to be done and
  • 01:07:58really great collaborations happening.
  • 01:08:01Thank you very much.
  • 01:08:02I'll be happy to answer any questions later.
  • 01:08:07That was really an outstanding talk.
  • 01:08:09Thank you Bruce,
  • 01:08:11and there was already one question.
  • 01:08:14If we want to take an hour later,
  • 01:08:15but it was about how cyber
  • 01:08:18knife radiation fits in,
  • 01:08:19and I think that was with regards to glioma.
  • 01:08:21So you can start thinking about that answer.
  • 01:08:25You know well and then also what
  • 01:08:27actually is the radiation as
  • 01:08:29compared to an X ray or dental X-ray?
  • 01:08:32So that's another radiation
  • 01:08:34question coming your way.
  • 01:08:36So we will conclude with Brian Jin
  • 01:08:39who's the licensed social worker who
  • 01:08:42leads our brain tumor support group.
  • 01:08:44Along with our team Jillian Bongard,
  • 01:08:48who's on as well and he's going to talk
  • 01:08:51about probably even more important than
  • 01:08:54surgery or radiation or chemotherapy.
  • 01:08:57But how we can support our
  • 01:08:59patients and their families?
  • 01:09:02Hello hello everyone,
  • 01:09:04thank you for that introduction.
  • 01:09:06I have the privilege of facilitating
  • 01:09:08the brain tumor support group with
  • 01:09:10Jillian and they have taught me a
  • 01:09:12lot and I think about them a lot
  • 01:09:14as I'm doing this presentation,
  • 01:09:15so I'll go ahead and bring up my funds.
  • 01:09:31So I'm Brian Jean.
  • 01:09:32I'm one of the clinical social
  • 01:09:35workers at Smilow Trumbull.
  • 01:09:37I work with primarily Dr and I
  • 01:09:41have the privilege of facilitating
  • 01:09:42the support group so my my role is
  • 01:09:45primarily supporting patients and
  • 01:09:47family both emotionally and also
  • 01:09:49helping them navigate the system,
  • 01:09:51find resources within the Community,
  • 01:09:53and it looks different for everybody.
  • 01:09:56So it really depends on what
  • 01:09:59families and individuals bring
  • 01:10:01to the table prior to diagnosis.
  • 01:10:04Every family system is extremely complex.
  • 01:10:07They bring different compositions.
  • 01:10:09They have different rules,
  • 01:10:10different stages of life,
  • 01:10:12they have different.
  • 01:10:13Previously existing diagnosis
  • 01:10:15that might impact how they respond
  • 01:10:18to maladaptive behaviors that
  • 01:10:19help them cope at one point,
  • 01:10:22but not that I don't know.
  • 01:10:27Identify the work work and
  • 01:10:30where we can have. So it's.
  • 01:10:35The framework that helps me helps
  • 01:10:38me navigate and support people,
  • 01:10:41and also I'll go through some of
  • 01:10:43the primary challenges that people
  • 01:10:44experience with the brain tumor,
  • 01:10:46and then I will go into ways
  • 01:10:48that smilo and the community
  • 01:10:50supports patients and families.
  • 01:10:55So one of the frameworks I use to help me
  • 01:10:57sort of identify and navigate and identify
  • 01:11:00the work is by Doctor Wallin's family,
  • 01:11:03system illness model and how it's useful.
  • 01:11:06Is it? It really takes the
  • 01:11:07whole family into account.
  • 01:11:08It really spends time looking at the system
  • 01:11:12and incorporating the medical team within it,
  • 01:11:14looking at the various ways that
  • 01:11:17families interact and support each other,
  • 01:11:19what strengths they have,
  • 01:11:21whether they bring culturally.
  • 01:11:22It's a very broad and very fluid model.
  • 01:11:25To use and then it breaks down the work,
  • 01:11:28both the emotional aspects and dimensions.
  • 01:11:31The concrete basic needs
  • 01:11:33that need to be addressed.
  • 01:11:34And also you know how these
  • 01:11:39interplays work with each other,
  • 01:11:41and then it takes it within
  • 01:11:44each freight phase of time.
  • 01:11:46What initially we experienced
  • 01:11:48during that first diagnosis period,
  • 01:11:50what it looks like when we become stable
  • 01:11:52and we found a period of equilibrium.
  • 01:11:55And then anytime we experience.
  • 01:11:58I need to change.
  • 01:11:59I need to adapt to a new
  • 01:12:02struggle or limitation.
  • 01:12:03So this is one of the ways it is
  • 01:12:07extremely useful for supporting families.
  • 01:12:10So the crisis phase.
  • 01:12:12This is the most difficult time this
  • 01:12:14is like being shot out of a cannon.
  • 01:12:17Oftentimes I've sat and heard the
  • 01:12:19stories of being diagnosed and being
  • 01:12:21in the car and suddenly having a
  • 01:12:23seizure and then waking up post
  • 01:12:25surgery and how they adapt to that.
  • 01:12:27How do they absorb that information
  • 01:12:29that's coming at them?
  • 01:12:30How their family is responding to suddenly?
  • 01:12:32Maybe the primary bed breadwinner
  • 01:12:34not being able to work.
  • 01:12:36What do you do at that time?
  • 01:12:37There's so many questions.
  • 01:12:38There's so many unknowns.
  • 01:12:40And fears that are arising at that time.
  • 01:12:43One of the things that is a challenge
  • 01:12:45is that they have to absorb this
  • 01:12:47new information about the diagnosis
  • 01:12:49that they would never assumed
  • 01:12:51they would encounter.
  • 01:12:52They have to understand medically,
  • 01:12:54they have to understand how it's impacting
  • 01:12:56their whole family system emotionally.
  • 01:12:58They have to understand it in the
  • 01:13:00short term and then the long term.
  • 01:13:01What is my plan?
  • 01:13:02What is what is my treatment
  • 01:13:04options and that what is one of
  • 01:13:06the things that helps people cope?
  • 01:13:08Having a really grounded and supportive plan?
  • 01:13:10Being connected to a medical providers
  • 01:13:13that can guide them through so.
  • 01:13:16These challenges as they arise,
  • 01:13:20they take a lot out of the family,
  • 01:13:22they they they they engender
  • 01:13:24a lot of uncertainty,
  • 01:13:26and one of the roles that I have
  • 01:13:28to support people with and is
  • 01:13:31identifying their strengths,
  • 01:13:32identifying their sense of faith,
  • 01:13:34what narratives they're using,
  • 01:13:36their family resiliency,
  • 01:13:37legacies that they have within themselves
  • 01:13:40that have helped them through adversity.
  • 01:13:43And we're looking for a stabilization.
  • 01:13:44We're looking for a place for the difficult.
  • 01:13:47Emotions a place for identifying
  • 01:13:48what they feel at the moment,
  • 01:13:51whether it be anxiety or feeling
  • 01:13:53overwhelmed or shocked and then
  • 01:13:55gradually lessening those giving
  • 01:13:57those a chance to sort of dissolve
  • 01:13:59and have their moment,
  • 01:14:00but then move towards the positive side.
  • 01:14:03And what is their course of action?
  • 01:14:08One of the big emotional things that
  • 01:14:10tends to come up that I see and oftentimes
  • 01:14:13isn't always identified as grief.
  • 01:14:15One a lot of times families are in the
  • 01:14:17state of shock and they've lost something.
  • 01:14:19They've even lost the ability to
  • 01:14:21look at life as this is stable.
  • 01:14:23This is known. This is safe.
  • 01:14:25I've had a family member say I'm
  • 01:14:26angry just looking at that family.
  • 01:14:28Going to the diner because
  • 01:14:30their life is so Monday.
  • 01:14:31It's so normal and now we're suddenly
  • 01:14:34thrown into a state of shock,
  • 01:14:36and these are the really the
  • 01:14:37challenges of the initial.
  • 01:14:38Phase is recalibrated,
  • 01:14:39finding order finding mastery,
  • 01:14:42finding competency and trusting
  • 01:14:43in their plan and collaborating
  • 01:14:45with their medical providers.
  • 01:14:49The next phase is.
  • 01:14:50Titled the chronic phase and this is
  • 01:14:53the the Phase I wish the support group
  • 01:14:55could be here to to share because
  • 01:14:58they're they're the they're the.
  • 01:15:00They're the ones who should give the the
  • 01:15:02master lesson and it's a difficult phase.
  • 01:15:04It's it has its own unique challenges.
  • 01:15:06One of the ones that universally
  • 01:15:08here is living with uncertainty and
  • 01:15:10any person who has had to go through
  • 01:15:12a scan and wait for the results
  • 01:15:14and knows what that feels like.
  • 01:15:16It holds all the hopes.
  • 01:15:18All the fears at the same time.
  • 01:15:20And this is a really.
  • 01:15:22Difficult thing to manage.
  • 01:15:23It produces a lawn being anxiety,
  • 01:15:25a lot of worry.
  • 01:15:26I know a lot of questions
  • 01:15:28that arise from that,
  • 01:15:29and the tendency is to projectors the future,
  • 01:15:32sometimes catastrophize and so
  • 01:15:34it can be a very challenging.
  • 01:15:38Emotional process to address,
  • 01:15:39but it's something that's going to
  • 01:15:41be universally have to be managed,
  • 01:15:43and you know the support group is one
  • 01:15:45of the the ways that we manage it.
  • 01:15:47You get.
  • 01:15:48Everybody coming together
  • 01:15:49to share how they cope,
  • 01:15:51everyone sharing the ways they managed it,
  • 01:15:54and a lot of it is really for me.
  • 01:15:56This is about being present,
  • 01:15:58being present in the moment,
  • 01:15:59connecting with what is good.
  • 01:16:01Connecting with makes you you happy.
  • 01:16:04You know that relationship
  • 01:16:05with the providers you know,
  • 01:16:07that's that's also there.
  • 01:16:08You know sometimes you're going
  • 01:16:10through all these treatments.
  • 01:16:11And and I've had patients say I want to.
  • 01:16:14I want a week off so I can go
  • 01:16:16to a wedding or a graduation.
  • 01:16:17And this is part of that.
  • 01:16:19Responsibility and where the report comes,
  • 01:16:23comes becomes so important and and and
  • 01:16:26another part that my support group.
  • 01:16:29Shared with me and is knowing your new
  • 01:16:31limitations and how do you transcend them?
  • 01:16:33What do you have to be sensitive to?
  • 01:16:35What can you do?
  • 01:16:36What can you have to modify and
  • 01:16:38finding that New Balance in life?
  • 01:16:40Which is is is a lot of work.
  • 01:16:43And in the final phase is transitions anytime
  • 01:16:46we have to find a new way of adapting.
  • 01:16:48If we're meeting a new struggle,
  • 01:16:50a new challenge,
  • 01:16:51that's the stage of change,
  • 01:16:54and that requires recalibration.
  • 01:16:56Again, maybe not as shocking.
  • 01:16:58Sometimes it is,
  • 01:16:59but there's different work to be done.
  • 01:17:02Sometimes this phase really hones in.
  • 01:17:06What is our priorities?
  • 01:17:07What is the most important
  • 01:17:09thing for us to do?
  • 01:17:10And it has its own special nuance.
  • 01:17:14So from there,
  • 01:17:16using this framework you know
  • 01:17:18there's different things to address.
  • 01:17:20Sometimes in that beginning it's a question
  • 01:17:22of how do I meet the world doesn't stop,
  • 01:17:25and unfortunately we have
  • 01:17:26to pay bills we have to do,
  • 01:17:29bring the kids to school.
  • 01:17:30It depends on everybody's stage
  • 01:17:31of life and where they are and
  • 01:17:33who they're responsible for.
  • 01:17:34And so one of the questions I
  • 01:17:36often get is like how do I?
  • 01:17:38How do I find the balance
  • 01:17:39of making ends meet
  • 01:17:41and prioritizing my health,
  • 01:17:42which is now my job?
  • 01:17:44Questions about disability,
  • 01:17:45whether or not you have short
  • 01:17:47or long term disability.
  • 01:17:49Applying for Social Security disability,
  • 01:17:51nobody gives us these this information
  • 01:17:53out in school or college or anywhere,
  • 01:17:56so these are one of the things you can access
  • 01:17:57through your team through your social worker.
  • 01:17:59You can ask your team if you
  • 01:18:01need assistance and help.
  • 01:18:02There are resources out in the community,
  • 01:18:04including the Connecticut
  • 01:18:06Bureau of Rehabilitation,
  • 01:18:07which you know will help people reengage in
  • 01:18:10a new profession or work with accommodations.
  • 01:18:13Your team can also be a source of.
  • 01:18:16Referrals to occupational health
  • 01:18:19things that get you back on your feet.
  • 01:18:22You're making you operate
  • 01:18:24a little bit better.
  • 01:18:25One of the big things for me is maintaining
  • 01:18:28health insurance because anytime we
  • 01:18:30have a shift from disability from employment,
  • 01:18:32there's concerns about making
  • 01:18:35maintaining health insurance.
  • 01:18:37There are Cobra,
  • 01:18:38there is Medicaid.
  • 01:18:40There's the access health CT
  • 01:18:42marketplace that's there.
  • 01:18:44Sometimes people are
  • 01:18:45transitioning to Medicare,
  • 01:18:47and which you can reach the choices program.
  • 01:18:49These are all very vital questions
  • 01:18:51for a lot of people who are are are
  • 01:18:53going through this process is how do
  • 01:18:55I take care of my family and myself,
  • 01:18:57both financially and health wise.
  • 01:19:01Emotional challenges well for
  • 01:19:03for brain tumors.
  • 01:19:04It it's been impressed upon me.
  • 01:19:08Just how much it is your identity.
  • 01:19:11This is who you are.
  • 01:19:11This is your signature.
  • 01:19:12You may be losing.
  • 01:19:14This might be your ability to drive,
  • 01:19:16it might be tied to your passion and
  • 01:19:18I think anytime I've worked with
  • 01:19:20individuals who have had a brain tumor,
  • 01:19:23there's been sometimes losses.
  • 01:19:24And there's also been that work to connect
  • 01:19:26to what it makes them feel good about life.
  • 01:19:29What makes them feel passionate and resonate?
  • 01:19:32And and this is something that our our
  • 01:19:34support group talks about in terms of.
  • 01:19:36How do you connect to gardening
  • 01:19:38even if you have a little bit of
  • 01:19:40limitations in terms of balance,
  • 01:19:42you'll find a way and that work is is.
  • 01:19:45Is there the two emotional
  • 01:19:47processes that I typically see.
  • 01:19:49I tend to focus on on very natural
  • 01:19:53emotional processes that this can be
  • 01:19:55a a traumatic event which triggers our
  • 01:19:58fight or flight survival mechanism.
  • 01:20:00A lot of times I see people in the crisis
  • 01:20:02stage where they're I'm hypervigilant
  • 01:20:04other than difficulty sleeping.
  • 01:20:06I'm a little bit more irritable and
  • 01:20:08I'm picking fights with my loved ones,
  • 01:20:09which is home normal because the
  • 01:20:11fact that you're in fight or flight,
  • 01:20:13you're primed for it.
  • 01:20:14Things are a little bit more difficult.
  • 01:20:17The problem is when it becomes
  • 01:20:18cyclical and it taps into anxiety
  • 01:20:20and becomes a habitual process.
  • 01:20:22Then we need to find a way to sort
  • 01:20:24of address it and find ways to sort
  • 01:20:25of pull you out of fight or flight.
  • 01:20:27That could be meditation.
  • 01:20:29It could be yoga and there'll be
  • 01:20:31other resources I'll talk about at
  • 01:20:32the end that you can connect to.
  • 01:20:34The other part is the Greek process and.
  • 01:20:36I always I'm a broken record with
  • 01:20:39this one because anytime any person
  • 01:20:41hits a limitation they suffer a brief
  • 01:20:44process and so this is something we
  • 01:20:46can't take a pill for. We can't avoid.
  • 01:20:48It's really about feeling it and
  • 01:20:50then doing good self care,
  • 01:20:52not getting stuck in it.
  • 01:20:53And so I really spent a lot of
  • 01:20:55time with individuals.
  • 01:20:58Talking about where is your safe
  • 01:20:59place to feel these emotions?
  • 01:21:00Who do you have to talk to about this?
  • 01:21:02And a lot of times it's our
  • 01:21:04spiritual practice because it sort
  • 01:21:05of addresses it existentially.
  • 01:21:09So this might seem strange.
  • 01:21:11The Unsought yes of brain tumor.
  • 01:21:15I I've been it's been remarkable how
  • 01:21:17many people who have gone through
  • 01:21:19such trials and hardships and loss.
  • 01:21:22Say they wouldn't change a thing and and
  • 01:21:24that's just an amazing thing to hear,
  • 01:21:26because what they've gained
  • 01:21:28from this experience,
  • 01:21:28their gratitude, their appreciation,
  • 01:21:30their recognition of what is most
  • 01:21:32important in their life is irreplaceable.
  • 01:21:35And it's not anything that can be replicated.
  • 01:21:38And you know,
  • 01:21:38that's it really taps into why we
  • 01:21:41fight and what makes us happy.
  • 01:21:42And it makes us more authentically ourselves.
  • 01:21:45Some people have shared,
  • 01:21:46like I wasn't happy before and
  • 01:21:48now I'm spending my time baking
  • 01:21:50bread and doing photography.
  • 01:21:52And and this is one of the things
  • 01:21:53that comes from this experience.
  • 01:21:55It's like altering and part of the
  • 01:21:57work that we do is making sure that
  • 01:21:59people access what makes the map.
  • 01:22:01What gives them purpose.
  • 01:22:02And you know when we hit limitations,
  • 01:22:04how do we transcend?
  • 01:22:09But just a note for the caregivers,
  • 01:22:11because there's a profound feeling
  • 01:22:13of healthiness helplessness,
  • 01:22:14being a caregiver,
  • 01:22:15I like to tell them they're always doing.
  • 01:22:17They're doing a great job.
  • 01:22:18They're just being there.
  • 01:22:19Being attentive, being attuned.
  • 01:22:21It's it's. It's,
  • 01:22:22they're doing enough and then self care,
  • 01:22:25just in terms of putting 2 moral
  • 01:22:28virtues together, you can never win,
  • 01:22:30so it's really vital for both patient
  • 01:22:33and family to spend time being soulful
  • 01:22:36and taking care of themselves.
  • 01:22:38So resources that we do have,
  • 01:22:41we have the brain tumor support group.
  • 01:22:43It's every third Monday,
  • 01:22:44three to four by Zoom.
  • 01:22:46You can reach out to me.
  • 01:22:48I can add you to the the list service.
  • 01:22:50We also have a caregiver support group
  • 01:22:52that is the 1st and 3rd of every Thursday.
  • 01:22:55It's in the evening to make it
  • 01:22:56a little bit more accessible.
  • 01:22:58Also by zoom, we have the meeting
  • 01:23:01centered psychotherapy group,
  • 01:23:02which is really,
  • 01:23:03how do you tap into the
  • 01:23:05meeting and through adversity?
  • 01:23:07We also have a cognitive behavioral skills.
  • 01:23:09Super Cancer Survivor is run
  • 01:23:11by Doctor Kilkis.
  • 01:23:12I put her email up there so if
  • 01:23:13you'd like and you're interested,
  • 01:23:15you can email her for the next session.
  • 01:23:18Additional resources. We have nutrition.
  • 01:23:20Any way to help you guys.
  • 01:23:21Holistically take care of yourself.
  • 01:23:23Support yourselves,
  • 01:23:23stronger as much as you can.
  • 01:23:26We have yoga guided imagery,
  • 01:23:28meditation, a lot of this is by zoom.
  • 01:23:30Unfortunately now we do have
  • 01:23:32art therapy classes.
  • 01:23:34We also have parenting at a challenging time.
  • 01:23:36As specifically for parents
  • 01:23:38with younger children.
  • 01:23:39You want guidance and ask what to
  • 01:23:42ask questions about communication,
  • 01:23:44developmental stages,
  • 01:23:45and how to share with their
  • 01:23:47kids what they're going to.
  • 01:23:48There's also palliative care,
  • 01:23:50which is a very comprehensive
  • 01:23:53team comprising psychiatry,
  • 01:23:55psychology, chaplain, social worker,
  • 01:23:58nurse, art therapy,
  • 01:23:59the whole gamut and they can
  • 01:24:01be very supportive and helpful.
  • 01:24:05Community resources the
  • 01:24:07Connecticut brain tumor alliance.
  • 01:24:09They provide education and peer support.
  • 01:24:11You can give them a call and you can
  • 01:24:13just speak to somebody who truly
  • 01:24:15understands what you're going through,
  • 01:24:16and we'll help you through for cancer.
  • 01:24:19There is ants place cancer care.
  • 01:24:21It's kids, hugs for families with children.
  • 01:24:25There's an American Cancer Society
  • 01:24:27which has a lot of educational
  • 01:24:29information and also some supports in
  • 01:24:31terms of staying like if you needed
  • 01:24:34to stay and receive radiation and.
  • 01:24:36This isn't your local you could.
  • 01:24:37You could access some of the
  • 01:24:40resources there's family reach for a
  • 01:24:42cancer patients which provides free
  • 01:24:45financial planning within an advisor.
  • 01:24:47There's the LIVESTRONG program,
  • 01:24:49which is allows people to go to YMCA's
  • 01:24:52for a tailored physical exercise
  • 01:24:56routine to help strengthen their body.
  • 01:24:59There's cancer in careers and triage cancers,
  • 01:25:01which it really helps people navigate.
  • 01:25:04Rejoining the workforce with their
  • 01:25:06cancer diagnosis and it gives
  • 01:25:08a lot of excellent resources.
  • 01:25:09There's financial grants for cancer patients.
  • 01:25:12There's cancer,
  • 01:25:13Connecticut Cancer Foundation and the
  • 01:25:15cancer cares for brain tumor specific.
  • 01:25:18There's a lovemark foundation and also
  • 01:25:20the Connecticut brain tumor alliance.
  • 01:25:25And just a closing note on for me.
  • 01:25:27You know. Occasionally people do require
  • 01:25:30additional assistance, and for the
  • 01:25:32younger patients I've been seeing,
  • 01:25:34that's the personal care waiver program.
  • 01:25:37The one thing that I've noticed is
  • 01:25:38the wait list is four to five years,
  • 01:25:40so if you ever have an opportunity
  • 01:25:42to call your state representative,
  • 01:25:44please do and say that's really unacceptable.
  • 01:25:47For older individuals,
  • 01:25:4865 years and older there is the Connecticut
  • 01:25:51Home Care program and this is long term.
  • 01:25:55There assistance at home
  • 01:25:56which is sometimes needed,
  • 01:25:58so these are these are the resources
  • 01:26:00are available if you have any
  • 01:26:02concerns reach out to your team.
  • 01:26:03They will guide you to somebody that can
  • 01:26:06help support you in any of these areas.
  • 01:26:08I just want to thank everyone for the
  • 01:26:11opportunity and just some references
  • 01:26:12and I had known disclosures.
  • 01:26:14Thank you guys.
  • 01:26:18Thank you Brian. It's always such a
  • 01:26:21beautiful talk and to hear you speak so
  • 01:26:23passionately about it and thank you again
  • 01:26:25to you and to Julian for the support
  • 01:26:27Group One question are our support
  • 01:26:29groups open to all patients or only
  • 01:26:32those being treated at your institution?
  • 01:26:34Absolutely open to all patients
  • 01:26:36and so the more the better.
  • 01:26:39And Brian, I don't know if you want
  • 01:26:41to put your contact in the chat
  • 01:26:43or do you want to put my contact
  • 01:26:45in the chat or whichever but.
  • 01:26:47Please reach out to us and and
  • 01:26:50everybody is welcome to come to the
  • 01:26:52support group and it's virtual,
  • 01:26:54which makes it really easily accessible.
  • 01:26:57All right, Bruce.
  • 01:26:58Back to you for those two tough questions.
  • 01:27:00So how does cyber knife radiation fit in
  • 01:27:03and what actually is the radiation as
  • 01:27:05compared to an X ray or dental X ray?
  • 01:27:09Alright thanks yeah, great question.
  • 01:27:10So cyber knife is really just the
  • 01:27:13name like a brand name of one of the
  • 01:27:16machines that does that stereotactic
  • 01:27:19technique which is 1 to 5 treatments.
  • 01:27:22There's quite a bit of
  • 01:27:24advertising around that machine,
  • 01:27:25especially in Connecticut.
  • 01:27:28With something good,
  • 01:27:29something I think a little misleading
  • 01:27:31and and things are kind of implying,
  • 01:27:33but it's a.
  • 01:27:34It's a very nice machine and
  • 01:27:36does a great job.
  • 01:27:36There are other machines that are equally
  • 01:27:39as good and are actually more flexible,
  • 01:27:41so for example that stood protocol
  • 01:27:42with six weeks of radiation that's
  • 01:27:44not possible with the cyber knife
  • 01:27:45that can only do the short treatment,
  • 01:27:47so it's a great tool in certain
  • 01:27:51programs and you know we used to
  • 01:27:54have one in our system up in the.
  • 01:27:58Through the same refills group that joined,
  • 01:28:00but ultimately we decided that we
  • 01:28:02like the the machines that are more
  • 01:28:04flexible that can do the stereotactic
  • 01:28:06and can do other treatments
  • 01:28:07and focus more more on those.
  • 01:28:09So a good machine, but with some limitations.
  • 01:28:11I think
  • 01:28:12I mean gamma radiosurgery
  • 01:28:13essentially is is the same.
  • 01:28:15It's just stereotactic radiosurgery.
  • 01:28:17Maybe one thing if you could mention,
  • 01:28:20I'm not sure if this is
  • 01:28:21what the person was asking,
  • 01:28:22but I think a good question that that
  • 01:28:25I always get all the time is why.
  • 01:28:28Why do you use?
  • 01:28:29Why can't you use radio surgery for GBM?
  • 01:28:31Whether it's cyber knife or gamma knife,
  • 01:28:33why do you have to use? So
  • 01:28:36yeah, that's a good question.
  • 01:28:37So yeah, the gamma knife,
  • 01:28:39which we do have it at Yale wonderful
  • 01:28:42program with Doctor Veronica Chang
  • 01:28:43Neurosurgery and then others helping
  • 01:28:45out from radiation college and so on.
  • 01:28:47But that machine uses radioactive
  • 01:28:50cobalt sources to all focus in.
  • 01:28:54It's really best at doing the
  • 01:28:56single fraction treatments.
  • 01:28:58The latest iteration can do
  • 01:28:59two and three treatments,
  • 01:29:00but it's probably it's best with
  • 01:29:02the with the one treatment,
  • 01:29:03and we especially use it
  • 01:29:05for brain metastases.
  • 01:29:06We have other machines like machine
  • 01:29:08is showing the being of the talk.
  • 01:29:09Those linear accelerators
  • 01:29:10that can also do it but are.
  • 01:29:11Let's say that's our number
  • 01:29:13one machine for it.
  • 01:29:14You know what's interesting about tumors
  • 01:29:16is that radiation is is remarkably
  • 01:29:18effective at a lot of different tumors,
  • 01:29:21but it has its limitation.
  • 01:29:23There's sometimes there's just not
  • 01:29:24enough dose that we can get to,
  • 01:29:25and sometimes we've we study what are called.
  • 01:29:28Those escalation trials where we
  • 01:29:29try to go higher and higher with
  • 01:29:32this more sophisticated machinery.
  • 01:29:34And sometimes you find that you know
  • 01:29:35what it just doesn't work better.
  • 01:29:37It there isn't as good as or no
  • 01:29:39better than the lower treatment,
  • 01:29:41or in fact it can be worse sometimes
  • 01:29:43because we have more side effects
  • 01:29:45and we're still not controlling
  • 01:29:46the tumor any better.
  • 01:29:48And so for glioblastoma in particular,
  • 01:29:50I think in the earlier days of gaming and
  • 01:29:52some of the machines people were saying,
  • 01:29:55hey,
  • 01:29:55this is a tumor that we're
  • 01:29:56struggling with and we didn't
  • 01:29:57know as much about some of these.
  • 01:29:58MGMT and all these.
  • 01:30:00These nifty things Doctor
  • 01:30:01Chrome was pointing out,
  • 01:30:03and so one thing would say hey,
  • 01:30:05but let's do more radiation and
  • 01:30:07I would say pretty uniformly.
  • 01:30:10Those efforts and trials were failures.
  • 01:30:12They just did not replace, didn't?
  • 01:30:15They certainly didn't replace the surgery,
  • 01:30:17can do, and even within radiation,
  • 01:30:19they just really weren't adding lots.
  • 01:30:22So at this point,
  • 01:30:24you know we very selectively use
  • 01:30:27radiosurgery techniques for people who had.
  • 01:30:29Usually multiple recurrences where
  • 01:30:31they are not a surgical candidate,
  • 01:30:33and I think in that respect,
  • 01:30:34and there's been a gap of time
  • 01:30:36since the original radiation.
  • 01:30:37It can be quite effective there,
  • 01:30:39and we're studying it with in
  • 01:30:41combination with certain other drugs,
  • 01:30:43as if we can make it more effective,
  • 01:30:45but but definitely not a substitute for
  • 01:30:48for surgery when when at all possible.
  • 01:30:52The other question,
  • 01:30:53so most these machines that we're
  • 01:30:56talking about whether cyber knife
  • 01:30:58or you know a true beam or any of
  • 01:31:01these ones are are using X rays.
  • 01:31:03Really X rays,
  • 01:31:04the gamma knife machine uses gamma rays
  • 01:31:06as it's a radioactive pieces of cobalt,
  • 01:31:09but most of them are these machines
  • 01:31:10and so they really share a fundamental
  • 01:31:13architecture with the same machine in
  • 01:31:15your dentist office or a mammogram,
  • 01:31:16or anything else.
  • 01:31:18The difference is that those diagnostic
  • 01:31:20X rays are in the kilovoltage.
  • 01:31:23Range is the energy and when
  • 01:31:24we treat with therapeutic
  • 01:31:25relations, the mega voltage range.
  • 01:31:28So it's 1000 times more energetic and
  • 01:31:31really has some unique properties about
  • 01:31:34how it can damage the tissues and which
  • 01:31:38then sets up the type of shielding
  • 01:31:39that's necessary and everything else.
  • 01:31:41So they are X rays, they're just
  • 01:31:43more powerful that we're using.
  • 01:31:47Great thank you. There was one final
  • 01:31:51question with regards to surgery.
  • 01:31:53Somebody who's watching from Germany.
  • 01:31:55So thanks for joining from Germany question
  • 01:31:57do we have any thoughts on the autologous,
  • 01:32:01all mental free flap technique from Doctor
  • 01:32:04John Boockvar and has this been done at Yale?
  • 01:32:07And so John is a a good friend of
  • 01:32:10mine and I'm familiar with his trials.
  • 01:32:12This one is is something just
  • 01:32:15to to update others about.
  • 01:32:17This is. Using a piece of
  • 01:32:20laproscopically obtained omentum,
  • 01:32:22which is highly vascularized with a pedicle,
  • 01:32:26a vascular pedicle to it,
  • 01:32:28and the idea there is to to bypass
  • 01:32:30the blood brain barrier and he's had
  • 01:32:32some other trials that had that same.
  • 01:32:35From type of of thought behind them,
  • 01:32:38bypassing the blood brain barrier
  • 01:32:39to get more direct targeted
  • 01:32:41therapy to the resection cavity.
  • 01:32:43We personally don't have that trial here.
  • 01:32:46We haven't tried that that trial here,
  • 01:32:49but we'll certainly look to to John
  • 01:32:51and his team to see how the the
  • 01:32:54results are early on in that trial.
  • 01:32:56I don't know if Zach you have
  • 01:32:59any thoughts or comments.
  • 01:33:01He does not.
  • 01:33:02All right, well it is 807 and I think
  • 01:33:05we are done with all of the questions.
  • 01:33:08It's really been a pleasure having my
  • 01:33:10friends and colleagues here tonight.
  • 01:33:12So thank you again to Zach and
  • 01:33:16Bruce and Brian.
  • 01:33:17Really wonderful talks.
  • 01:33:18Really a pleasure to work with all of you.
  • 01:33:20Thank you for everything you do for our
  • 01:33:22patience as part of the brain tumor center.
  • 01:33:25Thank you for being here tonight and
  • 01:33:27thank you to everyone for listening
  • 01:33:29to us and please reach out anytime.
  • 01:33:31Brian put his.
  • 01:33:33Email in that chat for the support
  • 01:33:35group and you can email me at
  • 01:33:38anytime with anything, all right.
  • 01:33:41So have a good night.
  • 01:33:43Thank you so much goodnight,
  • 01:33:45thank you.
