- 00:00See we are talking.
- 00:03Generally about the topic of uncle fertility,
- 00:07and more specifically about reproductive
- 00:11endocrinology and infertility.
- 00:14Referral for fertility preservation and
- 00:17patients undergoing chemotherapy or Granada.
- 00:21Toxic therapy as as the the the poster said.
- 00:27And we're joined by two members of
- 00:30the OB GYN department, both who are
- 00:33relatively young in their careers.
- 00:36I don't actually know who's going first,
- 00:39and I'm going to introduce both
- 00:41of them together as we start,
- 00:43and they can decide that.
- 00:44So we have two speakers.
- 00:46We have Tanya Glenn,
- 00:48who's originally from Rochester,
- 00:51MN and went to college at Truman
- 00:54State University in Missouri and then.
- 00:58Went on to attend medical school at Saint
- 01:01Louis University School of Medicine.
- 01:04And took the what is not such a common
- 01:07path of of joining the military and
- 01:11did a combined military and civilian
- 01:13residency at at Wright Patterson Air Force
- 01:16Base and Wright University in Dayton, OH.
- 01:19She's in her final year of REI training
- 01:22at Yale and is going to be taking a
- 01:25position at Brooks Army Medical Center.
- 01:29After completing her her
- 01:32fellowship this year.
- 01:35And she is joined by Gabriella Barouch Kim,
- 01:40who is from Los Angeles,
- 01:42originally received her
- 01:44undergraduate degree at UCLA,
- 01:46where she received a number of honors
- 01:50and went on to medical school at UCSF.
- 01:54She is a third year resident in
- 01:58OBGYN and is also interested in REI.
- 02:03And is in the process of applying
- 02:06for reproductive endocrinology
- 02:08and infertility fellowships as the
- 02:10parent of a child who went through
- 02:13the Yale OBGYN Residency.
- 02:14It's always nice to interact with the
- 02:17with with Yale OBGYN and residents,
- 02:20so they're they're here today and I'm
- 02:23I'm not entirely sure what order.
- 02:26I'm not entirely sure who's talking
- 02:28about what,
- 02:28but I'm going to leave it to the two of you.
- 02:30You're both on one screen and
- 02:31I think you can figure it out.
- 02:33Welcome, thank you for joining us.
- 02:37Thank you, thank you for having us.
- 02:40So I'm Gabriella.
- 02:41I'm here with Doctor Glenn.
- 02:43We're actually going to be
- 02:46Co presenting and Doctor
- 02:47Glenn is going to help answer
- 02:49questions at the end as well.
- 03:02OK, your slides. They look perfect.
- 03:06Perfect thank you so much.
- 03:09So today as you already mentioned,
- 03:11we're going to be talking about
- 03:14fertility preservation for patients
- 03:15undergoing gonadal toxic therapy.
- 03:20Neither Doctor Glenn nor
- 03:22I have any disclosures.
- 03:26So our objective with this talk is to try to
- 03:29raise awareness for fertility preservation.
- 03:32Encourage patient and provider discussions
- 03:34surrounding the implications of cancer
- 03:37treatment on future reproductive capacity,
- 03:40improve multidisciplinary collaboration
- 03:41between providers caring for these
- 03:44patients and reproductive specialists,
- 03:47and discuss options for fertility
- 03:50preservation for patients who hope to
- 03:53preserve their reproductive capacity.
- 03:55So first I'd like to start with a
- 03:58little bit of background on this topic.
- 04:00The term oncofertility was coined by
- 04:02Doctor Woodruff and it refers to a field
- 04:06of medicine concerned with minimizing the
- 04:08negative effects of cancer treatment on
- 04:11the reproductive system and fertility,
- 04:14with assisting individuals with reproductive
- 04:16impairments resulting from cancer therapy.
- 04:22So what population are we referring to
- 04:25when we discuss fertility preservation
- 04:27for patients undergoing cancer therapy?
- 04:31So over 200,000 people under the age of
- 04:3549 are diagnosed with cancer annually
- 04:38and 85% of patients less than 39 years
- 04:41old will survive for five years.
- 04:4670,000 new cases a year of cancer
- 04:50are diagnosed in adolescence and
- 04:53young adults of these patients,
- 04:56more than 90% of them,
- 04:58will survive for at least five years,
- 05:00and these patients tend to be healthier
- 05:03and tolerate more intense therapies,
- 05:05which is relevant because more
- 05:07intense therapies can drastically
- 05:09reduce the reproductive lifespan.
- 05:14Certain cancer treatments such as radiation,
- 05:17chemotherapy, and surgery,
- 05:18can lead to sterility and subfertility.
- 05:21So next I'd like to briefly discuss
- 05:24what some of the morbidities
- 05:26of are of these therapies.
- 05:29So specifically regarding radiation therapy,
- 05:32there are acute morbidities,
- 05:35including primary hypogonadism,
- 05:37premature ovarian insufficiency,
- 05:38which was previously referred
- 05:41to as premature ovarian failure,
- 05:44central hypogonadism,
- 05:45specifically for patients who are
- 05:47undergoing radiation to the brain,
- 05:50and then there are late morbidities,
- 05:52including secondary cancers that can
- 05:54result from radiation therapies,
- 05:56hypothalamic pituitary ovarian
- 05:58access deficiencies.
- 06:00Spinal cord dysfunction,
- 06:01which can potentially lead
- 06:03to impotence among males and
- 06:06infertility or ovarian insufficiency.
- 06:11Regarding the effects of chemotherapy,
- 06:14there are the effects of late morbidity,
- 06:16including infertility,
- 06:18premature ovarian insufficiency
- 06:20and primary hypogonadism,
- 06:23and there are increased risks
- 06:25specifically with people who are
- 06:27receiving alkylating agents or
- 06:29patients with Hodgkin's lymphoma or
- 06:31breast cancer with undergoing adjuvant
- 06:34therapy where at increased risk of
- 06:36premature ovarian insufficiency.
- 06:42Regarding stem cell therapies
- 06:44and the effects of those,
- 06:46those can lead to gonadal dysfunction
- 06:48and the late morbidity associated
- 06:51with those include secondary
- 06:53cancers and endocrine dysfunction.
- 06:57Lastly, there are the surgical effects
- 07:00of cancer therapies and the acute and
- 07:02long term effects of those include
- 07:04early menopause and sterilization.
- 07:07For example, if somebody would
- 07:09need to undergo removal of their
- 07:11ovaries or fallopian tubes.
- 07:15So different therapies have
- 07:18different reproductive reproductive
- 07:19risks associated with them,
- 07:22so high risk therapies include
- 07:24high dose pelvic radiation,
- 07:26radiation to the brain,
- 07:29hematopoietic stem cell transplantation,
- 07:32total body radiation or chemotherapy
- 07:35with high dose alkylating agents,
- 07:38whereas low risk therapies include
- 07:40low dose radiation to the pelvis,
- 07:43non alkylating chemotherapeutic drugs.
- 07:46Or antimetabolites.
- 07:51So now I'd like to transition a
- 07:52bit to discuss the importance
- 07:54of counseling these patients.
- 07:59So all patients of reproductive
- 08:02age who will undergo potentially
- 08:04gonadal toxic therapies should be
- 08:07receiving fertility counseling.
- 08:09This is in line with guidelines from the
- 08:12American Society of Clinical Oncology,
- 08:15which reports that all oncologic
- 08:18healthcare providers should be
- 08:20prepared to discuss infertility
- 08:22as a potential risk of therapy.
- 08:25The NCCN practice guideline also says
- 08:27that fertility preservation is an
- 08:29essential element of management of
- 08:32adolescents and young adults with cancer.
- 08:37That being said, less than half of US doctors
- 08:40inform cancer patients of childbearing
- 08:43age about fertility preservation,
- 08:46and only 47% of US doctors routinely
- 08:49refer cancer patients of childbearing
- 08:51age to reproductive endocrinologist.
- 08:5654% of oncologists do not discuss
- 08:59fertility, according to the JNC
- 09:01CN that was published in 2013,
- 09:05whereas specifically pediatric
- 09:06oncologists tend to do a bit
- 09:10better and 94% of pediatric
- 09:12oncologists discuss fertility.
- 09:16And what basically this highlights
- 09:18is that there is a discrepancy
- 09:21between the current guidelines and
- 09:23the reality regarding counseling,
- 09:26and this is something for all of us to
- 09:28work on and an area for improvement to
- 09:31increase access to fertility preservation.
- 09:36So what about Yale? What is going on?
- 09:40How are you doing with counseling at Yale
- 09:44regarding fertility preservation for patients
- 09:47undergoing therapy for their cancer?
- 09:51So we do have one study that looks into
- 09:54how what percentage of patients are being
- 09:58counselled specifically for patients
- 10:00who are prescribed cyclophosphamide.
- 10:03The study included 236 reproductive age women
- 10:08between December of 2019 and October of 2021.
- 10:14And of these 236 patients,
- 10:1833% received family planning
- 10:20counseling and 9% were offered
- 10:24ovarian tissue cryopreservation.
- 10:27There were certain factors which
- 10:29modified a patient's likelihood
- 10:31for receiving counseling and those
- 10:33included Caucasian race age,
- 10:35less than 40,
- 10:36and those who had living children were
- 10:39less likely to receive this counseling.
- 10:46So how can we improve access
- 10:49for fertility preservation?
- 10:54There are several things that need to
- 10:56happen for us to achieve that goal.
- 10:58One is to increase awareness.
- 11:02Next would be to assess patient's
- 11:05interest in receiving fertility,
- 11:07preservation treatment,
- 11:10as well as the provider
- 11:13providing basic counseling
- 11:15regarding fertility preservation.
- 11:17Placing a referral when indicated,
- 11:19and then ensuring that a patient
- 11:21is able to access this care.
- 11:27So how do we increase awareness?
- 11:31Well, patients are often overwhelmed
- 11:33by a cancer diagnosis, especially when
- 11:36they first receive that diagnosis.
- 11:38They can be worried about
- 11:39delays in cancer treatment,
- 11:41or they could just be unaware of the
- 11:45potential effects of their therapy
- 11:48on their reproductive capacity.
- 11:50The medical team already has a
- 11:53considerable amount of counseling to do
- 11:55when a patient receives this diagnosis,
- 11:58and oftentimes that the discussion of
- 12:01fertility preservation cannot be prioritized.
- 12:04However, the onus really falls on the
- 12:07medical team to be able to identify
- 12:10these patients who are at risk and to
- 12:13be able to provide basic counseling
- 12:15and place the referral to reproductive
- 12:17endocrinology when indicated.
- 12:21So what are some ways that we propose we
- 12:25optimize this awareness so one is just
- 12:28through education and collaboration,
- 12:30which is why doctor Glenn and I
- 12:33are here is to try to promote that
- 12:36and something else that we that
- 12:38we proposed was epic optimization,
- 12:42which we'll talk about a little
- 12:43bit more in the next slide.
- 12:47So something that Doctor Glenn and I
- 12:49had proposed to the Epic optimization
- 12:52team is to potentially have a hard
- 12:55stop when a new diagnosis of cancer is
- 12:58entered into a patients problem list.
- 13:01A provider could could encounter this alert
- 13:05that would require that they acknowledge
- 13:09a reason for either referring a patient
- 13:13to reproductive endocrinology or not.
- 13:16Facing a referral or acknowledging that
- 13:19this is not applicable for this patient.
- 13:24After a after a provider is met with
- 13:27this alert they would then when
- 13:30indicated either place a consult to
- 13:33gynecology when a patient is in the
- 13:36inpatient setting or if they are in
- 13:39the outpatient setting they would
- 13:41simply just place an REI referral.
- 13:43I just want to highlight here that when
- 13:47patients are in the inpatient setting,
- 13:50that console is a general consult to
- 13:53gynecology. Once that console is placed,
- 13:56the guide, the inpatient gynecology
- 13:59resident team will contact
- 14:01reproductive endocrinology.
- 14:05This can also be done for for preservation.
- 14:10For male patients, it would still be a
- 14:13gynecology consult in that case as well.
- 14:18So now regarding education,
- 14:21the Oncofertility Conservatorium was
- 14:23developed in 2007 to address the lack
- 14:26of knowledge concerning fertility,
- 14:28preservation and the National physicians
- 14:32cooperative includes 83 institutions,
- 14:35including oncologists,
- 14:36surgeons, endocrinologists,
- 14:38reproductive endocrinologist,
- 14:40urologist, rheumatologist, geneticist,
- 14:41and mental health providers,
- 14:44and below are also different links.
- 14:48That can be used by both providers and
- 14:52patients to promote education on this topic.
- 15:01And then regarding counseling.
- 15:02So there are several steps
- 15:04involved in counseling patients,
- 15:06including informing patients of
- 15:09the potential risks to fertility.
- 15:12Of their therapy,
- 15:14as well as just inquiring whether they
- 15:17desire to preserve their fertility.
- 15:19Referring patients to REI if
- 15:21they are interested as well as
- 15:23following up on those patients.
- 15:28At this point I want to just
- 15:30transition a bit to discuss to
- 15:33discuss patient perspectives and
- 15:34hopefully this will help highlight
- 15:37again the importance of this topic.
- 15:43So in a study that looked at
- 15:46female cancer survivors. Umm?
- 15:50There was an increased rate of
- 15:53pregnancy termination among female
- 15:55cancer providers due to a fear of the
- 15:57effect of their therapies on their
- 16:00future on their future children,
- 16:02and what this really highlights
- 16:04is a gap in education.
- 16:08This study also showed that 91%
- 16:11of female cancer survivors felt
- 16:13that their quality of life was
- 16:15improved after receiving counseling
- 16:17and treatment about fertility.
- 16:22There was also a cross sectional study
- 16:26concerning fertility after cancer,
- 16:28where the primary outcome was use of
- 16:32fertility treatment and in this study,
- 16:3575% of participants reported that having
- 16:38a biological child was important to them.
- 16:4215% of these participants
- 16:44actually used fertility services.
- 16:46And survivors were less likely to pursue
- 16:50infertility treatment due to a fear of
- 16:53adverse effects on their personal health,
- 16:56which again highlights a
- 16:57gap in their education.
- 17:02Other patient perspectives include a survey
- 17:04from the Journal of Clinical Oncology.
- 17:07In this survey, 81% of teen girls and
- 17:1193% of their parents would be interested
- 17:15in fertility preservation, even if that,
- 17:17even if that method were to be experimental.
- 17:24In a survey from the Journal of
- 17:27Assisted Reproduction and Genetics.
- 17:3012.5% of patients reported that they were.
- 17:33They would regret if they were unable
- 17:35to use the tissue that they preserved
- 17:39for ovarian tissue preservation.
- 17:41In these patients and parents felt
- 17:44more in control of their decision
- 17:46with receiving this counseling.
- 17:52Other patient perspectives.
- 17:54There are studies and surveys that
- 17:56indicate that 26 to 80% of individuals
- 18:00remember discussing fertility.
- 18:02This range really highlights the
- 18:04variability in each practice.
- 18:0868% of males and 14% of females
- 18:11remembered being offered a referral
- 18:13for fertility preservation.
- 18:17And then this last statistic reports
- 18:20that female survivors were less
- 18:22likely to be prescribed infertility
- 18:25medications after seeking help,
- 18:28and that relative risk was 0.57.
- 18:31And what this shows us is that there's
- 18:34also a lack of education among providers.
- 18:39So next, I'd like to speak about the
- 18:41different methods that can be offered
- 18:43to patients for fertility preservation.
- 18:48So there are many proven as
- 18:50well as experimental methods
- 18:52for preserving fertility.
- 18:53These include gamete or embryo
- 18:57cryopreservation, ovarian tissue,
- 18:59or whole ovary preservation,
- 19:01suppression of damage which
- 19:03can include decreasing the
- 19:05dose of a certain therapy or
- 19:07using an alternative therapy.
- 19:09Decreasing the dose to the gonads,
- 19:12or steel or shielding the gonads
- 19:15or avoidance of damage entirely,
- 19:17which could entail.
- 19:18Removing the gonads or using
- 19:20an alternative therapy.
- 19:24So to discuss some of the proven methods,
- 19:27the gold standard is considered
- 19:30embryo cryopreservation.
- 19:31This process includes stimulating
- 19:33the ovaries with gonadotropins,
- 19:36surgically retrieving oocytes,
- 19:38inseminating the O sites,
- 19:40culturing them for three to five days,
- 19:43and then cryo preserving them.
- 19:46This tends to have a high success
- 19:48with 90% survival of embryos and
- 19:51live birth rates between 22 to 35.
- 19:54Percent, this whole process
- 19:56takes about two to three weeks,
- 19:58and some of the cons include
- 20:00exposure to high dose hormones,
- 20:02the time involved,
- 20:03and the fact that the that the patient
- 20:07would need either partner or donor sperm.
- 20:11Another option is mature
- 20:14O site cryopreservation.
- 20:15This tends to have slightly lower success
- 20:18rates between 50 and 90% survival.
- 20:21That's likely due to attrition of the
- 20:24O sites, as they need to be frozen,
- 20:27thawed, then inseminated.
- 20:29And sorry it fertilized and
- 20:34after fertilization matured.
- 20:36This process takes essentially the
- 20:38amount the same amount of time as.
- 20:40Embryo choir preservation.
- 20:42There are fewer ethical objection
- 20:45objections and no partner is required
- 20:49for oversight chair preservation.
- 20:51Another proven method includes O for praxy.
- 20:55This has a success rate between 16 and
- 20:5890% and involves fixing the ovary to
- 21:01the pelvic brim with a surgical clip.
- 21:04This is typically used for
- 21:06patients who will be exposed to,
- 21:08for example,
- 21:09radiation therapy to the pelvis and
- 21:11what it's essentially doing is moving
- 21:14the gonads away from that site.
- 21:17There are no ethical obligations,
- 21:20I'm sorry there's no ethical objections
- 21:23to over prexy and enables a patient
- 21:26to be able to use their own O sites
- 21:30and there's no stimulation required.
- 21:32Some of the cons include that.
- 21:39It really depends on a
- 21:41patient's vascular system.
- 21:42It depends on their age.
- 21:44It depends on the dose of
- 21:47radiation that they're receiving,
- 21:49and it can also be affected if
- 21:52the area is not shielded. The.
- 21:59Other methods for.
- 22:01For fertility preservation,
- 22:04include ovarian tissue cryopreservation.
- 22:07This was previously thought to be
- 22:11experimental and is now a proven method
- 22:13and involves obtaining ovarian cortical
- 22:16tissue prior to ovarian failure.
- 22:19The tissue is obtained via
- 22:22laparoscopy or laparotomy.
- 22:23The tissue is dissected into into
- 22:26small fragments, cryopreserved,
- 22:27and then can later be transplanted.
- 22:30Most typically,
- 22:31that's done as an orthotopic.
- 22:33Transplant and not a heterotopic transplant.
- 22:37Live birth rates are between 23
- 22:40to 25% and this is particularly
- 22:44useful for prepubescent girls,
- 22:47and it can also be used as a
- 22:49form of endogenous hormones.
- 22:51Once this tissue is retransplantation.
- 22:55Some of the cons include.
- 22:58That reimplantation of potential
- 23:03cancer potential cancer.
- 23:06Once the tissue is removed and
- 23:08then reimplanted the uncertain
- 23:10life span of this tissue.
- 23:12The fact that it requires surgery
- 23:14and may require IVF down the line
- 23:18and the age limit such that patients
- 23:20who are typically over the age of 40
- 23:22will have less benefit in this case.
- 23:29Next, I'd like to go over just
- 23:32a few experimental methods
- 23:33which include whole ovary,
- 23:35including pedicle cryopreservation.
- 23:36This is typically reserved for very young
- 23:40patients whose ovaries are very small,
- 23:43for which ovarian tissue, cryo.
- 23:46Location would be very difficult.
- 23:49Another experimental method
- 23:50includes GNRH agonist therapies.
- 23:53The thought process with this is that we
- 23:56shut down the ovaries while a patient
- 24:00is receiving their cancer therapy,
- 24:02and the thought is that when
- 24:04these ovaries are less active,
- 24:06they'll be less susceptible to the
- 24:08harmful effects of the therapies.
- 24:13Some alternative options for patients
- 24:15include the use of donor eggs,
- 24:17the use of donor ombria embryos,
- 24:20surrogates or adoption.
- 24:27Lastly, to go over what happens
- 24:29post treatment for these patients.
- 24:31So regarding evaluation of
- 24:33their fertility down the line,
- 24:35most reproductive endocrinologists
- 24:37or gynecologists would look for
- 24:39patients to resume their menstrual
- 24:41cycle as well as test their anti
- 24:44mullerian hormone level to get a
- 24:46proxy of their ovarian reserve.
- 24:51Regarding the use of medications
- 24:53and outcomes for these patients,
- 24:56generally we use the same medications.
- 24:59However, as already mentioned,
- 25:00if a patient has an
- 25:03estrogen sensitive cancer,
- 25:04we can consider adding letrozole
- 25:07and aroma taste inhibitor or
- 25:10tamoxifen to reduce the exposure
- 25:13to high levels of estradiol.
- 25:18There are lower pregnancy rates in
- 25:21the first five years with autologous
- 25:24with use of autologous O sites and
- 25:27that lower pregnancy rate is 60%.
- 25:29However, notably,
- 25:30if someone were to use donor O sites,
- 25:33pregnancy rates tend to be fairly comparable.
- 25:39Regarding pregnancy complications,
- 25:41pregnancy does not affect recurrence
- 25:44of any cancer and generally pregnancy
- 25:47complications tend to be very low.
- 25:50The one exception to this is that
- 25:53some patients who receive very high
- 25:55dose of radiation to the uterus,
- 25:57especially at a young age,
- 25:59can potentially have a bit higher risk.
- 26:04Pregnancy outcomes and
- 26:06pregnancy complications.
- 26:09Regarding risk to offspring,
- 26:11there is no increased risk of anomalies.
- 26:14However, a provider may consider
- 26:15referring a patient to a genetic
- 26:18counselor specifically, if there is
- 26:20a genetic predisposition to cancer.
- 26:25Some other concerns that I'd
- 26:27like to briefly discuss include
- 26:30some safety concerns so.
- 26:32It should be determined by
- 26:35a multidisciplinary team,
- 26:36including the medical oncologist
- 26:39and reproductive endocrinologist.
- 26:41As to a discussion of the risks,
- 26:44benefits, preferences,
- 26:45and prognosis of this patient
- 26:49to discuss whether pursuing
- 26:51fertility preservation would
- 26:52be safe for the patient.
- 26:58There should also be consideration
- 27:02paid to trying to prevent any
- 27:06delays in in oncologic treatment.
- 27:09Regarding the legal implications,
- 27:11we should acknowledge the legal
- 27:14implications of not following the
- 27:15standard of care as well as the medical
- 27:19liability and potential malpractice with
- 27:21omission of information specifically
- 27:23regarding the the risks of cancer
- 27:27therapies on reproductive capacity.
- 27:32Additionally, the ethical considerations
- 27:34to consider that every patient has the
- 27:38right to know their options concerning
- 27:40fertility preservation as well as the
- 27:43risks and costs associated with that.
- 27:45Post humus utilization.
- 27:46This typically will depend on
- 27:49a patient's advance directive.
- 27:53Minors who are diagnosed with
- 27:55cancer will typically require
- 27:56a surrogate decision maker.
- 27:59And of course,
- 28:00the cost of these therapies.
- 28:05Just to briefly discuss the cost.
- 28:09There is legislation regarding
- 28:11costs specifically in Connecticut.
- 28:14In general, in 1942,
- 28:15the US Supreme Court acknowledged that
- 28:18procreation is a basic civil right
- 28:21and then specifically in Connecticut.
- 28:23We do have the fertility preservation bill.
- 28:27This was an acted,
- 28:29and basically it ensures that patients
- 28:32are covered for fertility preservation.
- 28:35If they have a medical necessity and having
- 28:40prior cancer treatment is considered,
- 28:44makes fertility preservation
- 28:46a medical necessity,
- 28:47and so patients who have private insurance.
- 28:53Have have this cost covered under this bill.
- 28:58Unfortunately,
- 28:58that bill does not cover the cost
- 29:01for people without insurance
- 29:02or for people with Medicaid,
- 29:04and so there are other means to try to
- 29:07reduce that cost for those patients,
- 29:09and they are listed below.
- 29:12So for example,
- 29:13with repro tech,
- 29:15they provide discounted long
- 29:16term storage of ovarian tissue
- 29:19as well as O sites and embryos,
- 29:22specifically regarding the cost of
- 29:24ovarian tissue prior preservation
- 29:26that one tends to be a bit costly.
- 29:28And can be between 12 to 24,000.
- 29:30However,
- 29:30this can also vary based off
- 29:32of the patient's income.
- 29:36And so lastly, to summarize,
- 29:38some of the things that we discussed today.
- 29:41Certain cancer treatments
- 29:42such as chemotherapy,
- 29:43radiation and surgery can lead to
- 29:46sterility and subfertility all patients
- 29:49of reproductive age who will undergo
- 29:51potentially genotoxic therapies
- 29:53should receive appropriate counseling.
- 29:55Some of the methods to try to optimize
- 29:58access to fertility preservation
- 30:00and include increasing awareness,
- 30:02promoting education and counseling,
- 30:05and collaboration, and methods.
- 30:07To preserve fertility,
- 30:08include embryo 4 O site cryopreservation,
- 30:12O for paxi, ovarian tissue cryopreservation,
- 30:15or experimental methods.
- 30:18Thank you so much for your attention.
- 30:21Here are some of our references and
- 30:22we're happy to answer any questions.
- 30:26There's.
- 30:34OK, so we have a question
- 30:37here regarding oh for proxy.
- 30:39The range of success rates listed
- 30:42are quite wide, from 10 to 90%.
- 30:44I had heard roughly a 50% chance
- 30:47of damaging the ovary directly
- 30:49from the procedure itself,
- 30:50which seems a high risk since since the
- 30:53risk from radiation is also probabilistic.
- 30:56Does Yale offer this option?
- 30:59What do the success rates look like
- 31:02in modern practice and what patients?
- 31:04Do well versus poorly with this approach.
- 31:15I actually have not seen any
- 31:18perplexity done here at Yale,
- 31:19but it is actually a simple procedure.
- 31:21It's the same thing.
- 31:22If we had some with ovarian torsion,
- 31:24it's actually the same procedure to be done,
- 31:26so it's something that we can actually do.
- 31:28I haven't seen a whole lot of public
- 31:30radiation patients come through. I
- 31:32couldn't give you the exact
- 31:33statistics, mainly because
- 31:36the problem is is like it varies on dose.
- 31:41Where it's located?
- 31:42Are they shielding or not?
- 31:43And so that's why you see that wide range.
- 31:46So even with Uber,
- 31:47Paxi would probably still
- 31:48recommend doing an additional.
- 31:52Fertility preservation procedure like
- 31:55tissue or embryo cryopreservation.
- 31:57Just to make sure that if there
- 31:59is any scatter from the radiation
- 32:01that we're still protecting
- 32:02them as much as possible.
- 32:06So I have a question for you, so, UM,
- 32:08you know. Obviously these issues come
- 32:10up with a fair amount of frequency,
- 32:13and I'm struck that you gave a great talk,
- 32:18but one of you is going off to take
- 32:21a job in Texas and and Gabriella,
- 32:25you're going off to do a
- 32:27fellowship in another year.
- 32:28So who on the in in the REI?
- 32:32Faculty is interested in these issues,
- 32:34who we should approach?
- 32:37Well, Gavin, be here for
- 32:39another year and so I
- 32:42understand that. But you know,
- 32:44again. So in training
- 32:47no, absolutely. And so we're
- 32:49working with Doctor Callan as well,
- 32:51and she does mainly the probably the
- 32:53most of the fertility preservation.
- 32:56But the fellows all work together too,
- 32:59so it's everything's just
- 33:00kind of passed down for.
- 33:02So my second year fellow,
- 33:03who's a rising third year now Eric Kahn,
- 33:06would be another good point.
- 33:08Of reference as well.
- 33:14There's another chat. The questions.
- 33:19Can you talk a little bit more
- 33:21about your outpatient services?
- 33:22How quickly can these patients be seen,
- 33:24particularly those who need to start
- 33:26anti cancer treatment quickly?
- 33:28Absolutely. So usually the third
- 33:30year fellow actually does all of
- 33:33the at least the Medicaid referrals
- 33:35and other referrals as well.
- 33:37If you just mark them urgent,
- 33:38we usually can see them within
- 33:40a week if not faster inpatient.
- 33:42Of course we see within 24 hours a lot
- 33:44of times it's just be like video chat
- 33:46so we can just talk about the options.
- 33:48And start getting things set up on our end,
- 33:51but usually we see people very
- 33:53quickly and you know we manage to
- 33:55squeeze them in somewhere because
- 33:57we know how important this is and.
- 34:00You know the hard part is when patients
- 34:03you know are not stable enough,
- 34:05and those are probably the hardest patients,
- 34:06and so usually if they have to
- 34:09undergo cancer treatment immediately,
- 34:11we want to make sure that they know how
- 34:12to find us afterwards so we can start
- 34:14planning after their treatment as well.
- 34:17Ohh Kurt,
- 34:18is there any movement to extend reproductive
- 34:21coverage to patients with Medicaid?
- 34:23I wish I've not seen any movement from.
- 34:26Fortunately for that,
- 34:27I think there's this an ongoing struggle.
- 34:30The hard part too is.
- 34:31I'm not originally from East Coast,
- 34:33but since all the states are so small
- 34:35each time you move states we see a
- 34:37lot of patients from Rhode Island and
- 34:38Massachusetts and New York and all of
- 34:40those states have different policies
- 34:42when it comes to fertility preservation,
- 34:44and so it makes it very difficult
- 34:46to keep up with. I think,
- 34:48but I have not seen any
- 34:50improvement in that area.
- 34:55Can you clarify if the quality
- 34:56of life statistic is independent
- 34:58of whether or not the patient
- 35:01used preservation strategies?
- 35:02I think the stress is the
- 35:03importance of referral,
- 35:04regardless of whether or
- 35:05not you have time. Yes,
- 35:08it does. Patients, even if they
- 35:11cannot pursue the treatment.
- 35:12Especially they can't pursue it immediately.
- 35:14Still appreciate the counseling that
- 35:17they receive so that they're aware of it.
- 35:20It's not 10 years down the road that they're.
- 35:22Surprised by this outcome.
- 35:29Something as well as that
- 35:30we're doing a lot more ovarian
- 35:32tissue crime preservation.
- 35:33I'm doctor ate. Who's a Yale physician,
- 35:36but recently has been working
- 35:39a little bit more with us.
- 35:41He does the ovarian tissue crime
- 35:43preservation, he kind of based out of
- 35:44New York when he comes down and does
- 35:46ovarian just require preservation,
- 35:48and does a lot of research on fertility,
- 35:50preservation, and so we're lucky to have
- 35:52him and that we can kind of continue.
- 35:54Still other areas that we're
- 35:56trying to improve on is, you know,
- 36:00testicular tissue prior preservation.
- 36:02Hopefully we will get more.
- 36:03There's only like 1 area,
- 36:05I think in Philadelphia or
- 36:07Pittsburgh around here.
- 36:08That does that for prepubescent boys,
- 36:10that is still experimental,
- 36:12but there's a lot of different
- 36:14things that we're just trying
- 36:16to bring more to Yale so that we
- 36:18can ensure that we kind of cover
- 36:20everyone for fertility preservation.
- 36:22When it comes to male fertility preservation.
- 36:25It's usually if they're postural,
- 36:27very straightforward.
- 36:28If there's any problem with ***********
- 36:30or the patients are unable to do so,
- 36:32we just have our colleague from Urology, Dr.
- 36:34Honig, help us with that,
- 36:37but we have our own andrology
- 36:39lab and store sperm here.
- 36:46Any other questions?
- 36:51Well, thank you both.
- 36:53It was really great and we
- 36:55look forward to interacting
- 36:57with your colleagues in the in
- 36:59the years ahead and good luck.
