Fertility Preservation: Has the Time Come? Friday August 9, 2019 Current Concepts in Men's Health, Saratoga, NY Adam S. Howe, MD Pediatric Urology Albany Medical College Albany, NY
Objectives 1. Assess the risk of infertility in patients undergoing iatrogenic gonadotoxic therapies 2. Understand the importance of onco-fertility and fertility preservation to patients and families undergoing cancer therapies 3. Explore different management options for fertility preservation (FP), including established, novel, and future therapies 4. Learn how to start up a fertility preservation program at your institution
“No patient should be excluded for consideration of discussion of fertility preservation for any reason including age, prognosis, socioeconomic status or parity” American Society of Clinical Oncology, 2013
Iatrogenic Infertility Cancer patients are surviving longer Certain patients are at increased risk of infertility due to side effects or complications of therapies treating other conditions. It is our duty as healthcare providers to discuss these risks and offer management, if possible, to increase the chance of fertility for these patients.
Conditions with increased risk of infertility Oncology Immunosuppression – Hematologic – Autoimmune / Rheumatologic / Nephrotic – Transplant Disorders of sex development and transgender Trauma (eg, testicular/ovarian torsion) Urological / Gynecologic
Estimation of Infertility Risk in Cancer Challenging due to several factors: the disease stage site cumulative treatment dose (chemo + rad + sx) age gender
Chemotherapy that causes sub-fertility in males (azoospermia) - Chlorambucil* - Carmustine* - Cyclophosphamide* - Lomustine* - Procarbazine - Busulfan - Melphan* - Ifosphamide* - Cisplatin* - Nitrogen Mustard* - Bleomycin *Alkylating Agents!
Chemotherapy: Females (amenorrhea) High Risk: Intermediate Risk: Low Risk: - Busulfan* - Adriamycin - Actinomycin D - Chlorambucil* - Carboplatin* - Bleomycin - Cyclophosphamide* - Cisplatin* - 5-Fluorouracil - Ifosphamide* - Methotrexate - Melphalan* - Vincristine - Nitrogen mustard* - Procarbazine *Alkylating Agents!
Novel agents Note: Tyrosine kinase inhibitors, mTOR inhibitors, and monoclonal antibodies have an unknown risk to fertility
Radiation: Males - Testicular radiation > 1.2 Gy - Total body radiation > 12 Gy - Cranial radiation > 40 Gy
Radiation: Females - Total body irradiation for bone marrow or stem cell txp - Craniospinal radiation dose >25 Gy - Pelvic or whole abdominal radiation dose: – Pre-pubertal: >10-15 Gy – Post-pubertal: >5-10 Gy - Oocyte median lethal dose
Risk of Sub-Fertility in Females Acute Ovarian Failure Occurs immediately following treatment Associated with full abdominal or pelvic radiation or hematopoietic stem cell transplant Should counsel prior to starting therapy Premature Ovarian Failure Ovarian failure before 35 yo Associated with alkylating agents Should counsel survivors in late adolescence
Patient Concerns Discussions about fertility and preservation of this are of great importance to patients – Cancer survivors place great importance on having children later in life and report psychological distress related to fertility loss Patients may make treatment decisions based on fertility concerns Parental influence in children and adolescents
Fertility Preservation All newly diagnosed cancer patients should be informed of potential risk of compromised fertility from the proposed treatment plan, along with being informed of fertility preservation (FP) options Fertility preservation procedures ideally should be performed before the start of therapy The decision to pursue FP is up to the patient and family, declining to pursue FP is acceptable.
Fertility Preservation Interventions
Options for Males Sperm banking Testicular biopsy for cryopreservation
Sperm banking Suitable for boys Tanner stage 3 and above 60-86% success rates (pregnancy) Referral to reproductive endocrinologist Can be given a private room to produce a sample when inpatient which will be immediately transported to storage center Can be collected via electro-ejaculation if required
Sperm banking Botchan 2013 – Low usage rates (10%) – Normal concentration but low motility – Testicular cancer with worst semen qualities – 66% conception rate Kamischke 2004 – Low ejaculate volumes for pts
Testicular tissue for cryopreservation Option for pre-pubertal boys and post- pubertal boys who are unable to produce a semen sample via ejaculation Simple scrotal surgery under general anesthesia with coordination of other procedures Contraindicated in patients with acute leukemia not in remission
Testicular tissue for cryopreservation Wu 2012 – Successful ICSI or natural mating in mice Pietzak 2015 – 81% boys over 6mo had adult spermatogonia – 44% over 6 yrs had primary spermatocytes Sandri-Ardekani 2011 – Successful xenotransplantation from humans to mice
Hormonal therapy Gonadoprotection through hormone manipulation for FP has not been shown to improve recovery of spermatogenesis in men and is not recommended.
Options for Females Oocyte Preservation Ovarian Tissue Cryopreservation Ovarian Transposition
Oocyte preservation Suitable only for post-pubertal females and considered established FP method 60-87% live birth rates Referral to reproductive endocrinologist Ovarian stimulation (10-12 days, 4 different protocols) GnRH antagonist-based protocols May not be suitable for patients with conditions that preclude a delay in starting therapy Transvaginal ultrasound for retrieval of oocytes
Oocyte preservation Wald 2019 – Oocytes yield doubled after back-to-back random-start ovarian stimulation prior to chemo – Mean time to complete 33 days Relchman 2012 – Successful cryo of 18 mature oocytes in 13 year old premenarchal female with myelodysplastic syndrome prior to chemo
Ovarian tissue for cryopreservation For pre-pubertal girls and post-pubertal girls who are unable to cryopreserve oocytes for any reason More than 60 cases of live births reported Ovarian tissue biopsy or oophorectomy via laparoscopic surgery under general anesthesia, cryopreservation, and future reimplantation (autotransplantation) or in vitro procedures Future reimplantation contraindicated in patients with leukemia Vide o
Ovarian tissue for cryopreservation Donnez 2013 – 30% pregnancy and 20% live birth rate (natural and IVF) after orthotopic reimplantation Poirot 2019 – Better pregnancy and live birth rates (32% vs 0%) in patients treated with chemo vs no chemo at 3 yrs after orthotopic/heterotopic reimplantation – Prior chemotherapy should no longer be a limitation to ovarian tissue cryo
Ovarian transposition (oophoropexy) Treatment strategy when pelvic radiation is performed for cancer treatment Laparoscopic surgery under general anesthesia placing the ovaries outside of the pelvis Preservation of ovarian function in 90%
Ovarian suppression therapy Gonadoprotection with GnRH analogs for FP in women show conflicting results and there is a lack of pediatric data. The ASCO does not support their use, therefore it is not recommended.
Conservative surgery Strategy utilized to retain fertility by performing less radical surgeries with the intent of sparing as much of the reproductive organs as possible. Examples: Partial orchiectomy for mass in a solitary testis Robotic trachelectomy for localized cervical cancer
Costs of FP 1st year Annually thereafter Sperm banking: ~$500 $400 Testicular tissue: ~$1,500 $400 Oocyte banking: ~$5,000 $400 Ovarian tissue: ~$2,000 $400 Oophoropexy: ~$1,000
Costs Currently, all costs are the responsibility of the patient/family The LiveStrong fertility program is available for patients to apply online to offset costs of coverage www.livestrong.org/what-we-do/program/fertility In 2017, Rhode Island and Connecticut became the first states to start covering FP procedures for patients undergoing cancer treatment
Legislation Recently, the Fertility Preservation Bill (formerly FAFTA [Fair Access to Fertility Treatment Act), S719 and A2817, has passed in New York state to add coverage for standard fertility treatments for those facing iatrogenic infertility
Albany Medical Center Fertility Preservation Program
Team members Urology Pediatric Hematology/Oncology Central NY Fertility (local site in Latham, NY)
Process 1. Hematology/Oncology initiates discussion of FP with patients before starting therapy 2. If patient desires and is a candidate for FP, referral to Urology for education with the family and consent to FP intervention 3. Blood screen for transmittable disease markers (syphilis screen, Hep C virus serology, Hep B antigen and antibody, HIV1/HIV2) 4. Referral to CNY (consent and arrangements for sperm banking, ovarian stimulation, cryopreservation of samples) 5. Coordination of FP procedure with other surgeries (eg, mediport placement, bone marrow biopsy) 6. Day of procedure: CNY brings transport media to AMC, urology notifies CNY when biopsy or sample is finished and available for pickup 7. CNY sends report of biopsy to AMC (Urology & Heme/Onc)
Potential There are about 60 newly diagnosed pediatric cancer patients that present to Albany Med per year: – 32 Male (20 prepubertal, 12 postpubertal) – 28 Female (16 prepubertal, 12 postpubertal)
Case 13 yo female with pelvic rhabdomyosarcoma and no menses undergoing chemotherapy (vincristine, dactinomycin, cyclophosphamide, and irinotecan) Schedule to undergo pelvic radiation (total dose >50 Gy) Underwent successful laparoscopic left ovarian transposition and right ovarian cortex harvest for cryopreservation
Building a FP program at your institution
1. Strong connection between oncologists and fertility specialists Strong collaboration Support and opinion of oncologist's “primary care” can have significant impact on patient decision making Open communication crucial – Especially with modification of treatment plans
2. Building a FP team Reproductive endocrinologist Oncologist Anesthesia (experience with coordination) Pathologist (ovarian and testicular tissue) Lab personnel (experience with handling tissue banking) Genetic counselors Mental health professionals (help discuss ethical and legal issues) ***FP patient navigator (initial counseling and referrals)***
3. Design of FP consultation Use of patient decision aids, brochures, and websites Follow-up visits (can be by phone or email too) Additional contact with fertility specialist
