- 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.

- 01:24:34to 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.
