Ovarian Tissue Cryopreservation versus Other Fertility Techniques for Chemoradiation-Induced Premature Ovarian Insufficiency in Women: A Systematic Review and Future Directions
Current advances in cancer therapy have increased survival, emphasizing the need for life quality improvement. Fertility loss is common post-chemotherapy. Current guidelines establish embryo and oocyte cryopreservation to address premature ovarian insufficiency (POI). Ovarian tissue cryopreservation has also recently become an acceptable option for fertility preservation, particularly as it is the only option for pre-pubertal patients. Few definitions for optimum fertility outcomes, and few systematic reviews comparing embryo, oocyte, and ovarian tissue cryopreservation as a means of fertility preservation (FP) in pre- and post-pubertal female cancer patients exist. This systematic review aims to improve understanding of gonadotoxic effects of chemoradiation therapy in cancer patients, to analyze the different fertility preservation techniques and procedures available to women with chemoradiation induced ovarian insufficiency, and to compare and recognize the benefits of each technique in restoring fertility, sexual hormone function, and quality of life. Searches were conducted electronically on PubMed, Cochrane, and EBSCOHost, including clinical trials, prospective, and retrospective studies of female cancer patients undergoing anti-cancer therapy, with predefined MeSH terminology. Data were collected, analyzed, and compared. Non-randomized clinical studies were evaluated for risk bias through the Newcastle–Ottawa Scale. In total, 23 studies were included. From there, 647 patients opted for oocyte cryopreservation, 267 for embryo cryopreservation, and 1382 for ovarian tissue cryopreservation (OTC). A total of 175, 18, and 121 live births resulted respectively from oocyte, embryo, and OTC, respectively. Studies without live births discussed other fertility markers as indicators of improvement in sexual hormone function and fertility. The gonadotoxic effects of chemotherapy call for FP intervention. Oocyte and embryo cryopreservation/implantation are well-established procedures. With changing trends and life quality consideration, OTC is a promising interventional method for pre-pubertal patients facing the prospect of fertility loss.
Etiology, Risk Factors, and Management of Asherman Syndrome
Asherman syndrome is characterized by a triad of symptoms including pain, menstrual abnormalities, and infertility and is a result of intrauterine scar tissue after instrumentation of a gravid uterus. Saline sonohysterogram is typically the most sensitive diagnostic tool; however, hysteroscopy is the criterion standard for diagnosis. Treatment includes hysteroscopic-guided lysis of adhesion, with restoration of the anatomy of the uterine cavity. Several modalities are used in an attempt to reduce the reformation of scar tissue after surgery; however, there is no consensus on the ideal method. Stem cells and platelet-rich plasma are being explored as means of regenerative therapy for the endometrium, but data remain limited. At present, most individuals can have restoration of menstrual function; however, lower pregnancy rates and obstetric complications are not uncommon. These complications are worse for patients with a higher grade of disease. Efforts are needed in standardizing classification, reducing uterine instrumentation of the gravid uterus, and referring patients to health care professionals with clinical expertise in this area.
Abstract 6644: Investigating the effect of immune checkpoint inhibitors (ICI) on ovarian function in young patients with melanoma
Abstract Immune related adverse events (irAEs) from immune checkpoint inhibitors (ICIs) are well documented for nearly every organ system, except for the reproductive system. Mouse models have demonstrated that ICIs can decrease ovarian follicular reserve and impair oocyte maturation, which may have implications for fertility (PMID: 36008687). There are no studies investigating the effect of ICIs on fertility in humans. We sought to evaluate ovarian function in women treated with ICIs compared to untreated women by evaluating non-invasive surrogate markers of ovarian reserve, anti-müllerian hormone (AMH) and antral follicle counts (AFC). We enrolled women 18 - 40 years old diagnosed with stage III or IV melanoma. Participants underwent phlebotomy for AMH levels and a pelvic ultrasound to assess AFC. The medical record was retrospectively reviewed to obtain data on patient characteristics, treatments, and outcomes. A total of 14 patients with stage IIIA - IV melanoma participated. Six patients received ICI treatment before AMH and AFC testing while 8 had no prior ICI exposure. The ICI group ages ranged from 22-40 years with a median age of 31 years. The untreated group ages ranged from 25-39 years with a median age of 32 years. The time between starting an ICI and enrolling in the study ranged from 28 - 351 days. ICI regimens included ipilimumab/nivolumab, nivolumab, pembrolizumab, and atezolizumab (on a clinical trial). Four of these six patients experienced an irAE during their course, including: dermatitis, hepatitis, colitis, thyroid dysfunction, and adrenal insufficiency. Median AMH levels were lower for patients treated with ICIs (2.9 vs 4.0 ng/mL), as was median AFC (22.5 vs 23.5 ng/mL). Only three patients’ clinicians discussed fertility preservation. None of the patients underwent fertility preservation. Our study found lower AMH and AFC in women with melanoma who were treated with an ICI compared to untreated women. Although AMH and AFC are surrogate markers for ovarian reserve and fertility, and our study is a small cohort, these early results suggest that ICIs may impact ovarian function. Age is less likely to be a confounding factor as the median age of the treated group was younger than the untreated group. While these results are preliminary, when considered in conjunction with recent pre-clinical data showing changes within the ovaries after ICI treatment, fertility consultation should be considered for young women prior to ICI initiation. We are investigating associations between AMH, AFC, age, ICI exposure, and future pregnancies in an ongoing prospective study.

Pregnancy Outcomes Associated with Ovarian Hyperstimulation Syndrome: A Retrospective Cohort Study of Infertile Women
Abstract Objective To assess the relationship between ovarian hyperstimulation syndrome (OHSS) and adverse outcomes using population-based data in the United States. The hypothesis is that patients with OHSS were more likely to deliver preterm and more likely to have hypertensive disorders. Methods This retrospective cohort study identified 94 patients with OHSS and 183 matched referents in eight counties in Minnesota. Data were collected regarding pregnancy history, infertility treatment, and pregnancy outcomes. Using the Rochester Epidemiology Project, study subjects were identified from female patients, aged 18 to 49 years, who were diagnosed with infertility from January 2, 1995 to December 1, 2017, and had a pregnancy greater than 20 weeks' gestation. The primary outcome was preterm delivery or hypertensive disorder of pregnancy incidence in the OHSS group when compared with control patients. Chi-squared test, t test, and multivariate logistic models were used where appropriate. Results Patients with OHSS were more likely to deliver preterm (odds ratio, 2.14; 95% confidence interval, 1.26–3.65; P < 0.01), and their neonates were more likely to be small for gestational age (odds ratio, 4.78; 95% confidence interval, 1.61–14.19; P < 0.01). No significant differences between the groups were observed in any other outcome. Patients with OHSS are more likely to deliver preterm if they undergo fresh transfer compared with a freeze all and subsequent frozen transfer (odds ratio, 3.03, 95% confidence interval, 1.20–7.66, P = 0.02). Conclusion OHSS may lead to preterm birth and small-for-gestational-age neonates, which changes patient counseling and leads to arranging specialized obstetrical care for these patients with OHSS.
Platelet-Derived Exosomes Induce Cell Proliferation and Wound Healing in Human Endometrial Cells
Purpose of review Endometriosis is a complex benign gynaecologic condition with heterogenous presentations and a large impact on the global healthcare system and on the quality of life for millions of women. Currently, the gold standard for diagnosis involves direct visualization of lesions during surgery confirmed by histopathological diagnosis, resulting in an average delay in its initial diagnosis of 8–10 years. Therefore, the search for noninvasive diagnostic testing options has been subject to a large body of research. Recent findings Multiple potential biomarkers have been explored for noninvasive testing for endometriosis, including glycoproteins, inflammatory cytokines, immunological molecules, angiogenesis markers, hormones, micro RNAs (miRNAs), proteomics, metabolomics, genomics and the microbiome. Summary Although there are challenges to consider, areas for real promise and advancement in the noninvasive diagnosis of endometriosis are currently being explored with real promise in the area of miRNAs, proteomics, metabolomics, genomics and the microbiome.
Gastrointestinal symptoms as a predictor of deep endometriosis of the pelvic posterior compartment on magnetic resonance imaging
Objective: To determine if gastrointestinal (GI) symptoms can predict deep endometriosis (DE) of the posterior pelvic compartment on magnetic resonance imaging (MRI). Methods: Patients with suspected endometriosis undergoing endometriosis protocol MRI at an academic center between 9/1/2015 and 7/31/2018 were identified. Presenting GI symptoms were collected via a standardized survey instrument prospectively at initial presentation. MRI and interdisciplinary conference notes were reviewed to identify posterior compartment DE (rectosigmoid, uterosacral ligaments, posterior cul de sac, and pelvic side walls). Associations between symptoms and DE were evaluated. Results: A total of 104 patients met inclusion criteria, and 89 (85.6%) presented with at least one GI symptom. Posterior compartment DE was identified on MRI in 47 patients (45.2%). The GI symptom that most strongly predicted DE was a bowel movement resulting in pain relief (OR 3.36, 95% CI 1.31–8.61, p = 0.012), with sensitivity, specificity, positive and negative predictive values 0.42, 0.82, 0.67, and 0.63, respectively. Other GI symptoms such as nausea, vomiting, rectal bleeding, change in frequency of bowel movements, and pain exacerbation by bowel movements did not significantly correlate to having DE. Of the 15 patients with no GI symptoms, 5 were found to have posterior compartment DE. Conclusion: In patients with suspected endometriosis, those who noted that bowel movements relieved their pain had more than three times the odds of having DE of the posterior compartment on MRI. Preoperative evaluation with MRI may be of value in these patients; however, lack of gastrointestinal symptoms does not exclude the possibility of posterior compartment DE.
Abstract P4-11-02: Prevalence and impact of fertility concerns in young women with breast cancer
Abstract Introduction: Breast cancer treatments can impair fertility via direct gonadotoxicity (chemotherapy) as well as by introducing delays in childbearing that allow natural ovarian aging. Guidelines strongly recommend fertility counseling and consideration of fertility preservation techniques for premenopausal women who have not completed their desired childbearing at the time of cancer diagnosis. Prior studies have identified high rates of fertility concern but relatively low rates of fertility counseling and use of fertility preservation techniques. We sought to investigate rates of fertility counseling, use of fertility preservation techniques, and how fertility concerns impact cancer treatment decisions in a modern cohort of patients with breast cancer at a large academic medical center in the United States. Methods: All patients seen at Mayo Clinic Rochester with a new diagnosis (within the year prior) of stage 0-4 breast cancer were invited (by mail or in person) to participate in the Mayo Clinic Breast Registry. After informed consent, participants were asked to complete a baseline survey and annual follow-up surveys. On baseline and one-year surveys, patients were queried about desire for future children and fertility concerns. Nurse chart abstraction was used to collect information about tumor subtype, stage, and treatments received. We examined survey data from women diagnosed under the age of 50 who expressed an interest in having future biological children on either the baseline or year 1 survey between February 2015 and October 2020. Descriptive statistics were used to summarize the degree of fertility concern in this population, the impact of that concern on cancer treatment decisions, and steps taken to preserve fertility. Results: Between February 2015 and October 2020, 865 women under age 50 at diagnosis consented to the registry. Of these women, 627 completed a baseline and/or 1-year survey and 100 answered either “yes” or “unsure” to the question: “At the present time, do you wish to have any more biological children in the future?” on one or both surveys. Among the 100 women expressing interest in future child-bearing, 92% were white, 27% had node-positive and one had distant metastatic disease at diagnosis. The age at diagnosis ranged from 19 to 49 years, with a mean age of 33.8 years. Of the 75 who reported a desire for future children at baseline, 28% felt “somewhat concerned” about their future fertility and 40% felt “very concerned.” Of the 70 who reported a desire for future children on the year 1 survey, 17% felt “somewhat concerned” and 59% felt “very concerned.” For those “very concerned” about future fertility at year 1, 65% reported that this concern had a major impact on their treatment decisions. Often, that treatment modification entailed using endocrine therapy for less than 5 years; 52% of those who specified the type of treatment modification they had made indicated this option. Of note, six women who reported no desire for future biological children at baseline were “unsure” at year 1. At year 1, 93% of women recalled a discussion about fertility with their doctor prior to starting treatment, and 49% had taken steps to preserve fertility (32.5% with embryo cryopreservation, 20% with oocyte cryopreservation and 65% with a GnRH agonist; some selected multiple options). Conclusion: We found a reassuringly high rate of patient-reported fertility counseling and use of reproductive endocrinology technologies to preserve fertility in women who reported a desire for additional children at or soon after diagnosis with breast cancer. Consistent with prior studies, fertility concerns frequently impacted breast cancer treatment decisions. It is important to err on the side of inclusivity when providing fertility counseling because desire for fertility can change over time.

Adenomyoma Versus Leiomyoma: Not All Uterine Lesions Are the Same
Objective: To determine the clinical characteristics and prior medical and surgical treatments in women undergoing surgical excision of endometriosis for pelvic pain at a single institution. Methods: In this retrospective cohort study we identified 140 women with pathology-proven endometriosis who completed a preoperative standardized pain form and underwent surgery at an endometriosis center. Women were stratified into three groups for analysis: no prior surgery, 1 prior surgery, and 2+ prior surgeries. Results: The most common treatments used prior to seeking care were hormonal contraceptives (51.6%) and surgery (46.1%). More than half of women were diagnosed with pelvic floor dysfunction at time of presentation or prior to consultation. There was a significant relationship between an increasing number of surgeries (none vs 1 vs 2+) and gonadotropin-releasing hormone (GnRH) agonist use (19.0% vs 27.5% vs 56.0%, p = 0.003). Though not significant, a trend was noted between increasing surgeries and opioid use (20.6% vs 30.0% vs 40.0%, p = 0.17). There was a statistically significant relationship between multiple surgeries and illicit drug use ( p < 0.001). Conclusion: Patients with pelvic pain and endometriosis who have undergone multiple surgeries are more likely to have used GnRH agonists and report illicit drug use prior to presenting to specialized care.
