Preservation of Ovarian Tissue and Chemo-Radiotherapy
Preservation of Ovarian Tissue and Chemo-Radiotherapy
The purpose of this study is to assess the results of ovarian tissue freezing, such as
 resumption or initiation of menses (menstruation: the discharge of blood and tissue from the
 uterus that happens about every 4 weeks in females who are not pregnant) and pregnancy, prior
 to starting chemotherapy or radiation treatment (commonly used for cancer treatment or for
 other conditions such as multiple sclerosis, psoriasis, rheumatoid arthritis). Females who
 are about to undergo chemotherapy or radiation therapy for cancer or these other medical
 conditions may stop having menses and may not be able to produce a biological child. Girls
 who have not achieved puberty and are exposed to chemotherapy (alkylating agents) or
 radiation treatment, the risk is up to 22-50%. In contrast, girls older than 10 years, or who
 have achieved puberty, experience acute ovarian failure in over 50% of the cases. By freezing
 and preserving ovarian tissue will help prevent these outcomes. In fact, when you are
 considered cured of your disease, you will have another surgical procedure where your own
 ovarian tissue will be transplanted back to you. This surgery will increase the possibility
 of resuming/initiating menses and the chance to have a pregnancy.
At the present time, freezing of ovarian tissue is considered experimental and so thawing and
 future use of the tissue to initiate a pregnancy must be performed as part of a research
 program. With the patient's permission, a portion of her ovarian tissue will be frozen for
 her own use and a portion will be donated to a research pool.

 Twenty subjects/year will be participating in this study.

 Participation in this study will last until the patient's ovarian tissue is all used, or the
 patient decides to drop out of the study, or for the rest of her life. Freezing of ovarian
 tissue can be done only for research. Thawing and future use of the tissue to start a
 pregnancy must be done as part of a research program. After the age of 18, the patient will
 decide how and at what institution she wishes to use her own tissue in the future, for the
 purposes of becoming pregnant. The number of visits will be decided by the surgical procedure
 performed. The Investigators will contact the patient by phone, email, or mail until she has
 turned 18 years old, used her tissue or dropped out of the study (whichever comes first) to
 follow the patient's medical and fertility status over time and to ask questions about any
 future use of her frozen tissue and the possible results of the treatment. Depending on the
 patient's age at the time of enrollment, follow-up might be up to 30 years.

 PURPOSE Primary objective: To assess resumption/initiation of menses after surgical ovarian
 preservation (ovarian tissue explant followed by freezing and autologous transplantation).

 Secondary objective: To assess pre- and post-treatment production of various hormones, i.e.,
 anti-mullerian hormone (AMH), insulin-like growth factor-1 (IGF-1), inhibin-B, follicle
 stimulating hormone (FSH), luteinizing hormone (LH), and estradiol, by serum and histological
 measurements.

 Tertiary objective: To assess long-term sexual development, fertility competence, and
 lifespan of ovarian preservation via surgical autotransplant.

 RATIONALE Chemotherapy treatment with alkylating agents and/or total body irradiation will
 prevent normal pubertal development of uterus, ovaries, and breasts because of primary
 ovarian insufficiency (POI). Explant and autologous transplantation of ovarian tissue will
 prevent ovarian insufficiency and allow normal sexual development through puberty and
 fertility competence.

 RESEARCH DESIGN Prospective cohort study.

 STUDY PROCEDURES Subject Recruitment and Screening- Subjects will be recruited by referral
 from the St. Jude Children's Research Hospital (SJCRH) and Methodist-Le Bonheur physicians to
 the Reproductive Medicine clinics held by Dr. Laura Detti. Patients will undergo an informed
 consent process in accordance with St. Jude Children's Research Hospital (SJCRH) and
 Methodist-Le Bonheur Institutional Review Boards.

 Screening Visit- Complete medical history and physical exam; vital signs, height, and weight.
 Psychological Consult on impact of therapy.

 Laboratory testing- Lab results for Estradiol, follicle stimulating hormone (FSH),
 luteinizing hormone (LH), Anti-Mullerian hormone (AMH), Inhibin B, will be obtained from the
 patients' clinical charts. In addition, Electrocardiogram (ECG) (12-lead); Bone age scan (if
 pre-pubertal), Pelvic ultrasound (transabdominal or transvaginal, depending on the patient's
 age) will be obtained from the patients' clinical charts. If a pelvic ultrasound has not been
 obtained prior to surgery, the procedure will be performed under anesthesia prior to the
 patient undergoing surgery for ovarian tissue harvesting).

 Surgical Procedures- Unilateral oophorectomy will be performed by laparoscopy prior to
 undergoing chemo-radiation treatment as specified above. Subsequent ovarian cortex
 autotransplant will be performed by laparoscopy after the patients have been declared cured
 by their physicians.

 Laparoscopic procedures- Upon general anesthesia is induced, attention will be turned to the
 patient's abdomen where 3-4 0.5 cm skin incisions will be performed (one in the umbilical
 fold and 2 lateral incisions; possibly, a 4th suprapubic incision). Disposable, bladed,
 trocars will be inserted in the abdominal cavity. The ovaries will be identified and a
 unilateral oophorectomy will be performed by retroperitoneal clamping/dissection of the
 infundibulo-pelvic and utero-ovarian ligaments.

 A bipolar electrode will be used to assure accurate hemostasis and irrigation will be
 performed as needed. Upon retrieval of the trocars from the abdomen, the skin incisions will
 be reapproximated with 4-0 vycril sutures.

 The second laparoscopic procedure will be done to perform autologous ovarian tissue
 transplant by suturing the thawed cortex fragments to the recipient ovary using 7-0 Prolene
 (Ethicon, Johnson and Johnson, USA), using the technique described by Silber et al. (Silber
 et al., 2005; Silber and Gosden, 2007) applied during laparotomy for transplantation.

 As the transplanted tissue exhausts its function after the 1st autologous transplant, other
 laparoscopic procedures might become necessary over the years to transplant the rest of the
 cryopreserved tissue until no more tissue is available in the cryobank storage.

 Freezing Procedure- The process of vitrification will be started in the Operating Room or in
 the lab within 120 minutes from collection of the sample and will be completed in the
 University of Tennessee Center for Reproductive Medicine laboratory. The tissue will be
 subdivided into numerous vials for individual storage/thawing. This will allow selective
 thawing for autotransplant over multiple procedures, if necessary.

 Embryology laboratory procedures- The ovarian tissue that is stored for the patients will be
 used for autologous transplant. However, other techniques that are performed in the
 embryology laboratory may be available to the patients in the near future and might represent
 the best option for fertility preservation in patients with blood-borne cancers (i.e.:
 leukemia), in whom the risk of re-seeding cancer cells with tissue transplant is high.

 Follow-Up Evaluation- Study treatment will include a post-operative visit and following
 scheduled follow-up visits for the patients' initial disease during which a complete physical
 exam and psychological evaluation will be conducted, and laboratory testing will be obtained
 for follicle stimulating hormone (FSH), luteinizing hormone (LH), anti-mullerian hormone
 (AMH), and Inhibin B.

 Visits will be scheduled one month after explant and every 6-12 months until autotransplant
 of tissue and afterwards.

 Laboratory testing, Electrocardiogram (ECG) (12-lead), Bone age, Pelvic ultrasound may be
 repeated yearly, as part of the patient's scheduled follow-ups. Bone age assessment will stop
 when a bone age of 18 years is achieved.

 Patients who are going to develop ovarian insufficiency prior to or after puberty will
 undergo estrogen/progesterone therapy as per our institutional protocols.

 Follow-up will continue until the patient stays enrolled in the study or until she reaches 40
 years of age, or she goes in menopause and does not have, or does not desire, further tissue
 for transplantation.
