Abstract
OPINION STATEMENT Around 90% of breast tumours are diagnosed in the early stage, with approximately 70% being hormone receptor-positive. The cornerstone of adjuvant therapy for early-stage hormone receptor-positive breast cancer is endocrine therapy, tailored according to disease stage, biological characteristics of the tumour, patient's comorbidities, preferences and age. In premenopausal patients with hormone receptor-positive breast cancer, ovarian function suppression is a key component of the adjuvant endocrine treatment in combination with an aromatase inhibitor or tamoxifen. Moreover, it can be used during chemotherapy as a standard strategy for ovarian function preservation in all breast cancer subtypes. In the metastatic setting, ovarian function suppression should be used in all premenopausal patients with hormone receptor-positive breast cancer to achieve a post-menopausal status. Despite its efficacy, ovarian function suppression may lead to several side effects that can have a major negative impact on patients' quality of life if not properly managed (e.g. hot flashes, depression, cognitive impairment, osteoporosis, sexual dysfunction, weight gain). A deep knowledge of the side effects of ovarian function suppression is necessary for clinicians. A correct counselling in this regard and proactive management should be considered a fundamental part of survivorship care to improve treatment adherence and patients' quality of life.

Abstract
Background Breast cancer remains a global health issue, including in Indonesia, which has a relatively high incidence of breast cancer. Several theories have proved the role of estrogen in breast cancer carcinogenesis, but there is yet to be a preventive measure against breast cancer. Chemotherapy is one of the therapeutic modalities for breast cancer that disturbs ovarian function in producing estrogen due to damaged ovarian granulosa cells. Chemotherapy becomes an alternative option to decreasing circulating estradiol levels through interventions in ovarian functions, either by surgery, such as oophorectomy, or medications that disturb the ovarian functions. This study aimed to observe the estradiol levels in breast cancer patients before and after chemotherapy. Methods This was a prospective cohort study. We observed the estradiol levels before and after adjuvant chemotherapy in breast cancer patients. Subjects' characteristics are presented in mean ± standard deviation, distribution frequency, and percentage. Subjects' characteristics based on chemotherapy were tested using an independent t-test, Mann-Whitney U, and Chi-square/Fisher exact test. Effects of chemotherapy on estrogen levels were tested using the Wilcoxon rank test and Kruskal-Wallis test. Results A total of 194 research subjects were included. There were changes in estradiol levels before and after therapy. The decrease of estradiol levels in patients who did not receive chemotherapy was -6.9% (P > 0.05). Patients who received anthracycline cyclophosphamide (AC) regimen, paclitaxel and anthracycline (TA) regimen, paclitaxel, anthracycline and trastuzumab (TA + H) regimen, and platinum regimen experienced a significant decrease in estradiol levels (-21.4% (P < 0.05), -20.2% (P < 0.001), -31.7% (P < 0.01), and -23.7% (P < 0.05), respectively). Among chemotherapy groups, the estradiol levels before and after chemotherapy did not have significant differences (P = 0.937 and P = 0.730, respectively). Conclusion There are no significant differences in estradiol levels between chemotherapy and hormonal therapy groups. Patients in both groups have decreased estradiol levels after therapy, although patients in hormonal therapy do not experience as much decrease as those in chemotherapy.

Abstract
IMPORTANCE The increasing trend of delaying childbirth means that more women are being diagnosed with breast cancer before having given birth to their desired number of children. Although chemotherapy can significantly improve the prognosis of this population, it also causes ovarian damage, including premature ovarian insufficiency and infertility. Gonadotropin-releasing hormone agonists (GnRHa) have shown promising fertility protective activity in premenopausal women, but their clinical usage remains controversial. OBJECTIVE Here, we conducted a meta-analysis to assess the efficacy of GnRHa when administered concurrently with chemotherapy that included cyclophosphamide in the prevention of chemotherapy-induced ovarian damage in premenopausal women. EVIDENCE REVIEW An extensive literature search was performed using the PubMed, Embase, and Cochrane databases. Pooled odds ratios (ORs) with 95% confidence intervals (CIs) were determined. FINDINGS Eleven randomized controlled trials with a total of 1,219 participants were included in the analyses. A significantly higher number of women treated with GnRHa experienced the resumption of ovarian function after chemotherapy than those who did not receive this treatment (OR, 3.04; 95% CI, 1.87-4.94; P < 0.001). Regarding spontaneous pregnancy, a statistically significant difference was observed only in hormone receptor-negative participants (OR, 2.06; 95% CI, 1.03-4.11; P = 0.04). CONCLUSIONS AND RELEVANCE When treating premenopausal women with breast cancer, the administration of GnRHa concurrently with chemotherapy appeared to improve the resumption rate of ovarian function; however, the spontaneous pregnancy rate only improved in hormone receptor-negative patients. Thus, the use of GnRHa during chemotherapy may represent a feasible strategy for preserving ovarian function in women with breast cancer.

Abstract
A significant number of women receive a cancer diagnosis before their age of natural menopause. Among these patients, the most frequent neoplasms are breast cancer, gynecological, and hematological malignancies. Premature ovarian insufficiency and infertility are among the most feared short- to long-term consequences of anticancer treatments in premenopausal patients. Both patient- and treatment-related characteristics are key factors in influencing the risk of gonadotoxicity with the use of chemotherapy. The cryopreservation of oocytes/embryos is a standard strategy for fertility preservations offered to young women interested in future family planning, but it does not allow gonadal function protection during chemotherapy. Ovarian suppression with gonadotropin-releasing hormone agonist (GnRHa) during chemotherapy is now recommended as an option to reduce the risk of gonadotoxicity in order to avoid the negative consequences of premature ovarian insufficiency in premenopausal women receiving cytotoxic therapy, including those not interested in fertility preservation. This review summarizes the risk of treatment-induced gonadotoxicity in premenopausal patients and the evidence available on the protective role of administering GnRHa during chemotherapy to preserve ovarian function.

Abstract
As one of the problems and diseases for women before 40 years, premature ovarian failure (POF) could be characterized by amenorrhea, low estrogen levels, infertility, high gonadotropin levels, and lack of mature follicles. Causes of the disease involve some genetic disorders, autoimmunity diseases, and environmental factors. Various approaches have been employed to treat POF, however with limited success. Today, stem cells are used to treat POF, since they have the potential to self-repair and regenerate, and are effective in treating ovarian failure and infertility. As mesenchymal stem cell (MSC) could simultaneously activate several mechanisms, many researchers consider MSC transplantation to be the best and most effective approach in cell therapy. A good source for mesenchymal stem cells is human umbilical cord (HUCMSC). Animal models with cyclophosphamide are required for stem cell treatment and performance of HUCMSC transplantation. Stem cell therapy could indicate the levels of ovarian markers and follicle-stimulating hormone receptor. It also increases ovarian weight, plasma E2 levels, and the amount of standard follicles. Herein, the causes of POF, effective treatment strategies, and the effect of HUCMSC transplantation for the treatment of premature ovarian failure are reviewed. Many studies have been conducted in this field, and the results have shown that stem cell treatment is an effective approach to treat infertility.

Abstract
The objective was to evaluate the outcomes of in vitro maturation (IVM) cycles using gonadotropin releasing hormone agonist (GnRH-ag) triggering. A retrospective cohort of IVM cycles from January 2015 to December 2019 in a single university-affiliated centre was examined. Main outcome measures were: (i) IVM maturation rate; and (ii) IVM maturation result. Secondary outcome measures were: (i) metaphase II (MII) rate on the day of egg retrieval; (ii) final MII maturation rate; and (iii) pregnancy rates. A total of 98 IVM cycles were performed during the study period: 50 (51%) were triggered with GnRH-ag (17 received FSH priming and 33 did not) and 48 cycles (49%) were triggered by hCG (37 with FSH priming and 11 without). A significant (p = 0.01) difference was noticed in maturation rate on egg retrieval day, in favour of the GnRH-ag group, although not in the final maturation rate achieved. Pregnancy rates were comparable between treatment sub-groups. GnRH-ag triggering in IVM cycles is an optional triggering mode and can be considered an acceptable option, especially when fertility preservation is a concern. GnRH agonists resulted in higher maturation rate on day of oocyte retrieval, but no difference in the total maturation rate.

Abstract
The only clinically accepted method of fertility preservation in young women facing gonadotoxic chemo- and/or radiotherapy for malignant or autoimmune diseases is cryopreservation of embryos or unfertilized ova, whereas cryopreservation of ovarian tissue for future reimplantation, or in vitro maturation of follicles, and the use of gonadotropin-releasing hormone agonists (GnRHa) are still considered investigational, by several authorities. Whereas previous publications have raised the fear of GnRHa's possible detrimental effects in patients with hormone receptor-positive breast cancers, recent randomized controlled trials (RCTs) have shown that it either improves or does not affect disease-free survival (DFS) in such patients. This review summarizes the pros and cons of GnRHa co-treatment for fertility preservation, suggesting 5 theoretical mechanisms for GnRHa action: (1) simulating the prepubertal hypogonadotropic milieu, (2) direct effect on GnRH receptors, (3) decreased ovarian perfusion, (4) upregulation of an ovarian-protecting molecule such as sphingosine-1-phosphate, and (5) protecting a possible germinative stem cell. We try to explain the reasons for the discrepancy between most publications that support the use of GnRHa for fertility preservation and the minority of publications that did not support its efficiency.

Abstract
Historically, approaches designed to offer women diagnosed with cancer the prospects of having a genetically matched child after completion of their cytotoxic treatments focused on the existing oocyte population as the sole resource available for clinical management of infertility. In this regard, elective oocyte and embryo cryopreservation, as well as autologous ovarian cortical tissue grafting posttreatment, have gained widespread support as options for young girls and reproductive-age women who are faced with cancer to consider. In addition, the use of ovarian protective therapies, including gonadotropin-releasing hormone agonists and sphingosine-1-phosphate analogs, has been put forth as an alternative way to preserve fertility by shielding existing oocytes in the ovaries in vivo from the side-effect damage caused by radiotherapy and many chemotherapeutic regimens. This viewpoint changed with the publication of now numerous reports that adult ovaries of many mammalian species, including humans, contain a rare population of oocyte-producing germ cells-referred to as female germline or oogonial stem cells (OSCs). This new line of study has fueled research into the prospects of generating new oocytes, rather than working with existing oocytes, as a novel approach to sustain or restore fertility in female cancer survivors. Here, we overview the history of work from laboratories around the world focused on improving our understanding of the biology of OSCs and how these cells may be used to reconstitute "artificial" ovarian tissue in vitro or to regenerate damaged ovarian tissue in vivo as future fertility-preservation options.

Abstract
Chemotherapy-induced premature ovarian insufficiency (POI) is one of the potential drawbacks of chemotherapy use of particular concern for newly diagnosed premenopausal breast cancer patients. Temporary ovarian suppression obtained pharmacologically with the administration of a gonadotropin-releasing hormone agonist (GnRHa) during chemotherapy has been specifically developed as a method to counteract chemotherapy-induced gonadotoxicity with the main goal of diminishing the risk of POI. In recent years, important clinical evidence has become available on the efficacy and safety of this strategy that should now be considered a standard option for ovarian function preservation in premenopausal breast cancer patients, including women who are not interested in conceiving after treatment or that would not be candidates for fertility preservation strategies because of their age. Nevertheless, in women interested in fertility preservation, this is not an alternative to gamete cryopreservation, which remains as the first option to be offered. In this setting, temporary ovarian suppression with GnRHa during chemotherapy should be also proposed following gamete cryopreservation or to women who have no access, refuse, or have contraindications to surgical fertility preservation techniques. In this article, we present an overview about the role of temporary ovarian suppression with GnRHa during chemotherapy in breast cancer patients by addressing the available clinical evidence with the aim of identifying both the best candidates for the use of this strategy and the still existing gray zones requiring further investigation.

Abstract
BACKGROUND Breast cancer is the most common malignancy diagnosed in women of childbearing age. A breast cancer diagnosis in this young patient population can be uniquely complex to navigate when considering the potential impact of fertility loss associated with specific gonadotoxic therapies. Another unique challenge for young breast cancer patients is pregnancy-associated breast cancer (PABC), which occurs in approximately 1 of every 3000 pregnancies. Pregnancy adds a layer of complexity to breast cancer treatment planning as many therapies can affect the developing fetus. These two clinical challenges require nuanced multidisciplinary approaches to facilitate optimal treatment outcomes. We sought to review and summarize the management strategy options for both fertility preservation and PABC. METHODS A guideline and literature review was performed for fertility preservation, young patients with breast cancer, and pregnancy-associated breast cancer. RESULTS Fertility preservation options, both established and experimental, are detailed. Suggested clinical practice guidelines for PABC are also presented, which delineate breast cancer treatment recommendations based on pregnancy trimester. CONCLUSION A multidisciplinary approach to patient care, including oncologists and early referral to reproductive specialists, can provide young breast cancer patients with options for fertility preservation. Under the guidance of a multidisciplinary treatment team, PABC can also be diagnosed and treated to permit the best possible outcomes for the mother and the developing fetus.

Ovarian protection with gonadotropin-releasing hormone agonists during chemotherapy in cancer patients: From biological evidence to clinical application. Cancer Treat Rev 2018; 72:65-77. [PMID: 30530271 DOI: 10.1016/j.ctrv.2018.11.006] [Citation(s) in RCA: 67] [Impact Index Per Article: 11.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2018] [Revised: 11/07/2018] [Accepted: 11/30/2018] [Indexed: 01/13/2023]
Abstract
Survivorship issues are an area of crucial importance to be addressed as early as possible by all health care providers dealing with cancer patients. In women diagnosed during their reproductive years, the possible occurrence of chemotherapy-induced premature ovarian insufficiency (POI) is of particular concern being associated with important menopause-related symptoms, psychosocial issues as well as infertility. Temporary ovarian suppression by administering a gonadotropin-releasing hormone agonist (GnRHa) during chemotherapy has been studied to reduce the gonadotoxic impact of chemotherapy thus diminishing the chance of developing POI. Despite more than 30 years of research in both preclinical and clinical settings, the performance of this strategy has remained highly debated until recently. In particular, the potential mechanisms of action for the protective effects of GnRHa during chemotherapy are still not clearly identified. Nevertheless, important novel research efforts in the field have better elucidated the role of this option that is now endorsed for clinical use by several guidelines. This manuscript aims at providing an extensive overview of the literature on the use of temporary ovarian suppression with GnRHa during chemotherapy in cancer patients by addressing its biological rationale, the available preclinical and clinical evidence as well as the still existing grey zones in this field that future research efforts should address.

Abstract
BACKGROUND Triptorelin, a gonadotropin releasing hormone analogue, can be administered to postpubertal female individuals with cancer who receive chemotherapy to obtain menstrual suppression and decrease the risk of hemorrhage caused by thrombocytopenia. Our goal was to assess whether triptorelin also has a protective role against the gonadotoxicity of chemotherapy. PATIENTS AND METHODS This retrospective observational study includes all postmenarchal female patients who presented to our Unit from 2000 to 2015 and received chemotherapy for cancer. They were administered depot triptorelin. We evaluated long-term ovarian function in order to detect clinical signs of ovarian damage, miscarriages, and pregnancies. Laboratory follow-up consisted in dosing serum follicle stimulating hormone, luteinizing hormone, prolactin, estradiol, and progesterone. Ultrasound of the ovaries was performed as well. RESULTS Of 36 evaluable patients, 9 received hematopoietic stem cell transplantation (HSCT). The remaining 27 patients maintained normal ovarian function at clinical, laboratory, and ultrasound assessment. Five of them achieved spontaneous physiological pregnancy. Four of the 9 patients who underwent HSCT developed premature ovarian failure. CONCLUSION Our study suggests that gonadotropin releasing hormone-a administered during chemotherapy can prevent premature ovarian failure in patients treated without HSCT and that it is not enough to preserve the ovarian function during HSCT. Hence, a prospective randomized trial with a larger population would be recommended.

Abstract
PURPOSE To evaluate the available randomized controlled trials (RCTs) in the literature investigating the use of gonadotropin-releasing hormone agonist (GnRHa) co-treatment for ovarian preservation in women receiving chemotherapy. METHODS A systematic review of the literature was performed from 1960 through 2017 to identify relevant RCTs. Included patients had lymphoma, ovarian cancer, or breast cancer. The primary outcome was the proportion of women who retained ovarian function after chemotherapy. Extracted data points included study design, patient characteristics, and proportion of women who developed premature ovarian failure (POF). A risk of bias assessment was performed according to the criteria outlined in the Cochrane Handbook for Systematic Reviews of Interventions. The pooled odds ratio was calculated, and outcomes of individual studies were compared using the random-effects model with the inverse-variance method and the DerSimonian-Laird estimator. RESULTS Twenty-nine RCTs were identified, and 10 met criteria for inclusion in the meta-analysis. An analysis of patients who did not develop POF after chemotherapy revealed eight studies supporting the use of GnRHa (OR 1.83; 95% CI 1.34-2.49). The duration of benefit of GnRHa is unclear. An analysis of three studies with outcome data at 2 years revealed a non-significant OR of 0.53 (95% CI 0.22-1.30) for the preservation of ovarian function with GnRHa treatment. CONCLUSION GnRHa may have a protective effect against the development of POF after gonadotoxic chemotherapy; however, the duration of benefit is unclear and requires further study.

Abstract
OBJECTIVE To evaluate the effectiveness of gonadotropin-releasing hormone agonist (GnRHa) administration before and/or during cancer chemotherapy for the protection of ovarian reserve in premenopausal women without prior diagnosis of infertility. METHODS This was a systematic review and meta-analysis of randomized controlled trials (RCTs) comparing administration of GnRHa before and/or during chemotherapy vs chemotherapy alone. Eligible participants were premenopausal women at any stage of cancer, without previous diagnosis of infertility. An electronic database search in MEDLINE, CENTRAL, LILACS and ClinicalTrials.gov was performed. After selecting eligible studies, the relative risk (RR) was assessed for primary ovarian insufficiency (POI)/amenorrhea and for spontaneous pregnancy after completion of treatment. RESULTS Thirteen RCTs comparing concurrent use of GnRHa and chemotherapy (609 participants) with chemotherapy alone (599 participants) were eligible for meta-analysis. All trials were open-label and patients had been treated for breast cancer (n = 1099) or lymphoma (n = 109). GnRHa had a significant benefit on the risk of POI/amenorrhea (RR, 0.60; 95% CI, 0.45-0.79), which persisted in subgroup analysis for breast cancer (RR, 0.57; 95% CI, 0.43-0.77) but not for lymphoma patients (RR, 0.70; 95% CI, 0.20-2.47). The rate of spontaneous pregnancy after completion of treatment was higher in women receiving GnRHa plus chemotherapy compared with those receiving chemotherapy alone (RR, 1.43; 95% CI, 1.01-2.02). Overall, the quality of evidence was low due to the unclear risk of bias, short follow-up and lack of objective assessment of ovarian function and reserve. CONCLUSIONS Evidence, albeit of low quality, supports the use of GnRHa before and/or during chemotherapy to reduce the risk of POI and increase the probability of spontaneous pregnancy in the short term. Further high quality RCTs with more accurate assessment of ovarian reserve are needed to support definitive recommendations for clinical practice. Copyright © 2017 ISUOG.

Abstract
Increasing accessibility of fertility preservation (FP) options has permitted women to retain fertility following anticancer therapies. Several published guidelines have made recommendations for FP however their implementation into practice is currently unknown. In this review, we aim to provide oncology clinicians practical information about FP options for post-pubescent female cancer patients and recommendations for care delivery in order to answer preliminary questions and help triage whether FP referral is appropriate. Herein, we present a resource for oncology providers to guide them with FP discussions. Key points that are discussed in this critical review include: i) All cancer patients beginning a new plan of care should be informed of potential fertility risk. ii) If a woman requests further information on FP interventions, referral to a FP clinic should be made. iii) Given the evolving technologies in this area, patients should be informed of those which are proven and unproven, with oocyte and embryo preservation recognized as standard practice. iv) Random start (independent of menstrual cycle day) techniques are available to minimize oncologic treatment delays. v) Specific protocols for ovarian stimulation may be center-specific. vi) There is unlikely an increased cancer recurrence risk as a result of stimulation protocols in women with hormone-sensitive cancers. vii) Lastly, given the absence of consensus in the literature, routine use of GnRH analogs is not recommended for all cancer patients, however may be considered in select cases, such as high-risk women in whom definitive FP is not possible or feasible.

Abstract
Outcomes after hematopoietic stem cell transplantation (HSCT) for patients with both malignant and nonmalignant diseases have improved significantly in recent years. However, the endocrine system is highly susceptible to damage by the high-dose chemotherapy and/or irradiation used in the conditioning regimen before HSCT. Ovarian failure and subsequent infertility are frequent complications that long-term HSCT survivors and their partners face with a negative impact on their QoL. Several meta-analyses of randomized clinical trials showed that gonadotropin-releasing hormone agonist (GnRHa) administration in advance of starting standard chemotherapy decreases the risk of gonadal dysfunction and infertility in cancer patients, but GnRHa use for ovarian protection in HSCT patients is not fully determined. In this review, we are discussing the potential preservation of ovarian function and fertility in pubertal girls/premenopausal women who undergo HSCT using GnRHa in parallel with conditioning chemotherapy, focusing on the current data available and making some special remarks regarding the use of GnRHa.

Abstract
Aim In recent years, the importance of fertility preservation (FP) has increased. In vitro maturation (IVM), an important technique in FP, has started to be used in the clinic, but controversies persist regarding this technique. Here, a survey of IVM for FP is provided. Methods Based on a literature review, the applications of FP, methods of FP, IVM of oocytes that had been collected in vivo and ex vivo, maturation of oocytes after IVM for FP, cryopreservation of oocytes for FP, explanation of the procedures to patients, and recent research on FP using IVM were investigated. Results Although IVM for FP remains controversial, the application of FP is expected to expand. Depending on the age and disease status of the patient, various methods of oocyte collection and ovarian stimulation, as well as various needle types and aspiration pressures, have been reported. The maturation rate of IVM in FP ranges widely and requires optimization in the future. In regard to cryopreservation for matured oocytes, the vitrification method is currently recommended. Conclusion Regarding FP for patients with cancer, the treatment of cancer is prioritized; thus, the time and use of medicines are often constrained. As several key points regarding IVM remain unclear, well‐designed and specific counseling for patients is necessary.

Abstract
PURPOSE Gonadotropin-releasing hormone (GnRH) agonists have been used with adjuvant chemotherapy to protect ovarian function. However, there are no data on the actual pregnancy rates among young breast cancer patients receiving GnRH agonists and concurrent chemotherapy in Korea. METHODS Among patients who underwent surgery from January 2002 to April 2012, premenopausal patients aged between 20 and 40 years were included in the analysis. We retrospectively reviewed clinicopathologic features (e.g., age, obstetric and menstruation history), recurrence, and survival status. The rate of resumption of menstruation was calculated in all patients. In the married group, pregnancy and delivery rates were also recorded. RESULTS Among 101 patients, 19 were lost to follow-up and 82 were eligible for the analysis. Among them, 31 were married, 10 of 51 got married, and 41 remained unmarried through the follow-up period. Among the married patients, 15 became pregnant and gave birth to 19 babies, whereas 26 did not become pregnant. The pregnancy rate in the married group was 50.0% (15/30). Three of 15 pregnancies (20.0%) were multiparous. Most of the delivered babies were healthy and 80.0% of patients had no problems breastfeeding (12/15). More than half the patients in all groups recovered menstrual status within 12 months. CONCLUSION Fifty percent of young breast cancer patients who attempted pregnancy succeeded in pregnancy after adjuvant chemotherapy and GnRH agonists. Further studies that include control groups are required to confirm whether the use of GnRH agonists improves pregnancy.

Abstract
The ovary contains oocytes within immature (primordial) follicles that are fixed in number at birth. Activation of follicles within this fixed pool causes an irreversible decline in reproductive capacity, known as the ovarian reserve, until menopause. Premenopausal women undergoing commonly used genotoxic (DNA-damaging) chemotherapy experience an accelerated loss of the ovarian reserve, leading to subfertility and infertility. Therefore, there is considerable interest but little effective progress in preserving ovarian function during chemotherapy. Here we show that blocking the kinase mammalian/mechanistic target of rapamycin (mTOR) with clinically available small-molecule inhibitors preserves ovarian function and fertility during chemotherapy. Using a clinically relevant mouse model of chemotherapy-induced gonadotoxicity by cyclophosphamide, and inhibition of mTOR complex 1 (mTORC1) with the clinically approved drug everolimus (RAD001) or inhibition of mTORC1/2 with the experimental drug INK128, we show that mTOR inhibition preserves the ovarian reserve, primordial follicle counts, serum anti-Mullerian hormone levels (a rigorous measure of the ovarian reserve), and fertility. Chemotherapy-treated animals had significantly fewer offspring compared with all other treatment groups, whereas cotreatment with mTOR inhibitors preserved normal fertility. Inhibition of mTORC1 or mTORC1/2 within ovaries was achieved during chemotherapy cotreatment, concomitant with preservation of primordial follicle counts. Importantly, our findings indicate that as little as a two- to fourfold reduction in mTOR activity preserves ovarian function and normal birth numbers. As everolimus is approved for tamoxifen-resistant or relapsing estrogen receptor-positive breast cancer, these findings represent a potentially effective and readily accessible pharmacologic approach to fertility preservation during conventional chemotherapy.

Abstract
A cancer diagnosis in women of reproductive age has unique medical and psychosocial ramifications, especially with treatments that are known to cause gonadal toxicity. For patients who undergo chemotherapy, a multidisciplinary team approach is essential to ensure that the patients' reproductive wishes are addressed. Currently, embryo and oocyte cryopreservation are the standard of care for those who wish to preserve their fertility. The use of gonadotropin-releasing hormone agonists has been a source of debate with numerous studies that have investigated the efficacy on both fertility and ovarian function preservation. This review evaluates the current literature on the use of gonadotropin-releasing hormone agonists for preservation of gonadal function. Assisted reproductive technology is excellent for preservation of fertility but will not protect gonadal function. Protection of gonadal function is critical for the broader issues of health and quality of life as a result of a hypogonadal state. At this moment, gonadotropin-releasing hormone agonists are the only drug class available to protect gonadal function.

Abstract
IMPORTANCE Chemotherapy may result in a detrimental effect on ovarian function and fertility in premenopausal women undergoing treatment for early-stage breast cancer (EBC). To minimize risk of harm to ovarian function and fertility for patients in this setting, careful considerations should be made. Gonadotropin-releasing hormone agonists (GnRHa) have been suggested as an alternative to prevent the loss of ovarian function due to exposure to cytotoxic agents, but GnRHa use for ovarian protection in EBC patients is not fully resolved. OBJECTIVE To determine the effectiveness of GnRHa administered concurrently with chemotherapy for ovarian function preservation. DATA SOURCES PubMed, SCOPUS, and Cochrane databases were searched for studies published between January 1975 and March 2015. The abstracts of the American Society of Clinical Oncology Annual Meeting between 1995 and 2014 and the San Antonio Breast Cancer Symposium between 2009 and 2014 were searched as well. STUDY SELECTION Prospective, randomized, clinical trials addressing the role of ovarian suppression with GnRHa in preventing early ovarian dysfunction in premenopausal women undergoing treatment for EBC were selected. DATA EXTRACTION AND SYNTHESIS Data extraction was performed independently by 2 authors. The methodology and the risk of bias were assessment based on the description of randomization method, withdrawals, and blinding process. MAIN OUTCOMES AND MEASURES Rate of resumption of regular menses after a minimal follow-up period of 6 months following chemotherapy was used as a surrogate to assess the incidence of ovarian dysfunction. Additional secondary outcomes included hormone levels and number of pregnancies. Risk ratio estimates were calculated based on the number of evaluable patients. Analyses were conducted using a random effect model. RESULTS Seven studies were included in this analysis, totaling 1047 randomized patients and 856 evaluable patients. The use of GnRHa was associated with a higher rate of recovery of regular menses after 6 months (odds ratio [OR], 2.41; 95% CI, 1.40-4.15; P = .002) and at least 12 months (OR, 1.85; 95% CI, 1.33-2.59; P < .001) following the last chemotherapy cycle. The use of GnRHa was also associated with a higher number of pregnancies (OR, 1.85; 95% CI, 1.02-3.36; P = .04), although this outcome was not uniformly reported and fertility or rate of pregnancy was not the primary outcome in any of the trials. CONCLUSIONS AND RELEVANCE Gonadotropin-releasing hormone agonists given with chemotherapy was associated with increased rates of recovery of regular menses in this meta-analysis. Evidence was insufficient to assess outcomes related to GnRHa and ovarian function and fertility and needs further investigation.

Abstract
AIM This study analyzes our single-center, retrospective experience on 63 premenopausal breast cancer patients treated with monthly triptorelin and concomitant chemotherapy. PATIENTS & METHODS Concomitant chemotherapy and triptorelin were adopted as part of premature ovarian failure prevention strategy. RESULTS Age at diagnosis was the main factor influencing fertility preservation (p = 0.002). Compared with patients aged 41-45 years, the probability of menses resumption was almost threefold than for women aged 35-40 years, and significantly higher for women aged <35 years (hazard ratio: 9.0; p = 0.0001). The cumulative proportion among patients who resumed menses was 33.3% at 6 months, 75% at 12 months and 87.5% at 24 months. Seven patients attempted pregnancy, and five (71%) obtained healthy deliveries. CONCLUSION We observed an acceptable rate of fertility preservation. Age at diagnosis influences fertility preservation.

Abstract
In the last years, thanks to the improvement in the prognosis of cancer patients, a growing attention has been given to the fertility issues. International guidelines on fertility preservation in cancer patients recommend that physicians discuss, as early as possible, with all patients of reproductive age their risk of infertility from the disease and/or treatment and their interest in having children after cancer, and help with informed fertility preservation decisions. As recommended by the American Society of Clinical Oncology and the European Society for Medical Oncology, sperm cryopreservation and embryo/oocyte cryopreservation are standard strategies for fertility preservations in male and female patients, respectively; other strategies (e.g. pharmacological protection of the gonads and gonadal tissue cryopreservation) are considered experimental techniques. However, since then, new data have become available, and several issues in this field are still controversial and should be addressed by both patients and their treating physicians.In April 2015, physicians with expertise in the field of fertility preservation in cancer patients from several European countries were invited in Genova (Italy) to participate in a workshop on the topic of "cancer and fertility preservation". A total of ten controversial issues were discussed at the conference. Experts were asked to present an up-to-date review of the literature published on these topics and the presentation of own unpublished data was encouraged. On the basis of the data presented, as well as the expertise of the invited speakers, a total of ten recommendations were discussed and prepared with the aim to help physicians in counseling their young patients interested in fertility preservation.Although there is a great interest in this field, due to the lack of large prospective cohort studies and randomized trials on these topics, the level of evidence is not higher than 3 for most of the recommendations highlighting the need of further research efforts in many areas of this field. The participation to the ongoing registries and prospective studies is crucial to acquire more robust information in order to provide evidence-based recommendations.

Abstract
Systemic lupus erythematosus (SLE) is a chronic autoimmune systemic disease that mainly affects women of reproductive age. Emerging data from recent molecular studies show us that estrogen hormone plays a central role in the development of this disease. By acting via its cognate receptors ERα and ERβ expressed on immune cells, estrogen can modulate immune function in both the innate and adaptive immune responses. Interestingly, estrogen may also evoke autoimmune responses after binding to B lymphocytes leading to the generation of high-affinity autoantibodies and proinflammatory cytokines (so-called estrogen-induced autoimmunity). Unfortunately, reproductive function of young female patients with this disease is commonly compromised by different pathophysiologic processes. First, ovarian reserve is diminished even in the presence of mild disease suggesting a direct impact of the disease itself on ovarian function possibly due to ovarian involvement in the form of autoimmune oophoritis. Second, SLE patients with severe manifestations of the disease are treated with alkylating chemotherapy agent cyclophosphamide. Cyclophosphamide and other drugs of alkylating category have the highest gonadotoxicity. Therefore, SLE patients exposed to cyclophosphamide have a much higher risk of developing infertility and premature ovarian failure than do the counterparts who are treated with other less toxic treatments. Third, the functions of the hypothalamic pituitary ovarian axis are perturbed by chronic inflammatory state. And finally adverse pregnancy outcomes are more commonly observed in SLE patients such as fetal loss, preterm birth, intrauterine fetal growth restriction, preeclampsia-eclampsia, and fetal congenital heart block. We aimed in this review article to provide the readers an update on how estrogen hormone closely interacts with and induces lupus-prone changes in the immune system. We also discuss ovarian function and other reproductive outcomes in SLE patients and the current strategies to preserve their fertility in the light of the most recent evidence-based findings of the clinical trials and molecular studies.

Abstract
Fertility preservation is the process by which either oocytes (eggs) or sperm undergo an intervention to preserve their use for future attempts at conception. Consideration of fertility preservation in the pediatric and adolescent population is important, as future childbearing is usually a central life goal. For postpubertal girls, both oocyte and embryo cryopreservation are standard of care and for postpubertal boys, sperm cryopreservation continues to be recommended. Although all the risks are unknown, it appears that fertility preservation in most cases does not worsen prognosis, allows for the birth of healthy children, and does not increase the chance of recurrence.

Abstract
Fertility-preservation techniques for medical reasons are increasingly offered in national networks. Knowledge of the characteristics of counselled patients and techniques used are essential. The FertiPROTEKT network registry was analysed between 2007 and 2013, and included up to 85 university and non-university centres in Germany, Austria and Switzerland; 5159 women were counselled and 4060 women underwent fertility preservation. In 2013, fertility-preservation counselling for medical reasons increased significantly among nullipara and women aged between 21 and 35 years (n = 1043; P < 0.001). Frequency of GnRH applications slowly decreased, whereas tissue, oocytes and zygote cryopreservation increased. In 2013, women with breast cancer mainly opted for tissue freezing, whereas women with lymphoma opted for GnRH agonist. Women younger than 20 years predominantly opted for GnRH agonists and ovarian tissue cryopreservation; women aged between 20 and 40 years underwent a variety of techniques; and women over 40 years opted for GnRH agonists. The average number of aspirated oocytes per stimulation cycle decreased as age increased (< 30 years: 12.9; 31-35 years: 12.3; 36-46: 9.0; > 41 years: 5.7). For ovarian tissue cryopreservation, removal and cryopreservation of fewer than one ovary was preferred and carried out in 97% of cases in 2013.

Abstract
Breast cancer is the most common malignant tumor in women of reproductive age, and is characterized by a high survival rate owing to improved antineoplastic treatments. Young survivors face the prospect of a diminished fertility as a consequence of the gonadotoxic chemotherapy, and many are seeking ways to preserve their fertility. Embryo and/or oocyte cryopreservation following controlled ovarian stimulation is currently the fertility preservation method of choice, but breast cancer patients may have contraindications to exogenous gonadotropin administration and may not have enough time to undergo ovarian stimulation prior to chemotherapy. Fortunately, many other options are available for these women, such as the letrozole-follicle-stimulating hormone ovarian stimulation protocol, in vitro maturation of oocytes and ovarian tissue cryopreservation. In this review, we discuss the benefits and disadvantages of the different fertility preservation techniques that can be offered to breast cancer patients.

Abstract
It is estimated that bone loss occurs in 70 % of all patients dying from cancer, causing a significant disease burden in cancer patients. Bone loss is caused by cancer itself and its metastases, but also by cancer therapies. Of the cancer therapy-induced bone loss, hormone therapies are best known for their bone damaging abilities. However, chemo- and radiotherapy may result in bone loss too. In this review, direct and indirect effects of various chemotherapies (such as methotrexate, imatinib, and taxanes) that cause bone loss are discussed. Furthermore, we discuss bone loss caused by radiotherapy and radionuclides, of which the latter may be reduced with the introduction of the alpha-emitter Radium-223. Finally, agents preventing chemotherapy- or radiotherapy-induced bone loss, in particular denosumab and bisphosphonates, are being reviewed for their efficacy in preventing chemotherapy- and irradiation-induced bone loss in cancer patients.

Abstract
BACKGROUND Increasing age of first pregnancy among Italian women with premenopausal breast cancer makes adjuvant hormonal therapy a hot topic, justifying a survey on the therapeutic approach of Italian oncologists. MATERIALS & METHODS From April to July 2012, an 11-item electronic questionnaire was submitted to Italian oncologists and 611 out of 974 invited filled questionnaires were collected from all over Italy. RESULTS In total, 97.7% of patients aged <40 years needing only hormonal therapy would receive both tamoxifen and luteinizing hormone-releasing hormone agonists (LHRHa); 2.3% tamoxifen or LHRHa alone. For the majority of oncologists LHRHa was also the preferred choice to preserving fertility. CONCLUSION Results are rather consistent with major guidelines but with a greater use of LHRHa and aromatase inhibitor.

Abstract
INTRODUCTION The late effects of cancer treatment have recently gained a worldwide ubiquitous interest among reproductive endocrinologists, oncologists, and all health care providers. Despite many publications on this subject, there are many equivocal issues necessitating summary. The case for and against using GnRH-agonist for fertility preservation is summarized with the rationale that preventing ovarian failure may be better than treating it. AREAS COVERED We searched Medline in the last 10 years using terms: 'fertility preservation', 'female chemotherapy', 'Gonadotropin-releasing hormone (GnRH) analogues', 'GnRH agonists' 'gonadotoxicity', and 'cancer treatment'. We included mainly publications from the past 7 years, but did not exclude previous, commonly referenced publications. Here, we summarize the various methods available for fertility preservation and minimizing chemotherapy induced gonadotoxicity. EXPERT OPINION Until now, 20 studies (15 retrospective and 5 randomized controlled trial) have reported on 2038 patients treated with GnRH-a in parallel to chemotherapy, showing a significant decrease in premature ovarian failure (POF) rate in survivors versus 8 studies reporting on 509 patients, with negative results. Patients treated with GnRH-a in parallel to chemotherapy preserved their cyclic ovarian function in 91% of cases as compared to 41% of controls, with a pregnancy rate of 19 - 71% in the treated patients. Furthermore, over 10 recent meta-analyses have concluded that GnRH-a are beneficial and may decrease the risk of POF in survivors. Because most of the methods involving ovarian or egg cryopreservation are not yet clinically established and unequivocally successful, these young patients deserve to be informed with all the various modalities to minimize gonadal damage and preserve ovarian function and future fertility. Combining the various modalities for a specific patient may increase the odds of preservation of future fertility.

Abstract
The late effects of cancer treatment have recently gained a worldwide interest among reproductive endocrinologists, oncologists, and all health-care providers, and the protection against iatrogenic infertility caused by chemotherapy assumes a high priority. Here, we summarize the case for and against using GnRH-agonist for fertility preservation and minimizing chemotherapy-induced gonadotoxicity. The rationale and philosophy supporting its use is that preventing premature ovarian failure (POF) is preferable to treating it, following the dictum: 'an ounce of prevention is worth a pound of cure'. Despite many publications on this subject, there are many equivocal issues necessitating summary. Until now, 20 studies (15 retrospective and 5 randomized, controlled trials) have reported on 1837 patients treated with GnRH-a in parallel to chemotherapy, showing a significant decrease in POF rate in survivors versus 9 studies reporting on 593 patients, with results not supporting GnRH-a use. Patients treated with GnRH-a in parallel to chemotherapy preserved their cyclic ovarian function in 91% of cases when compared with 41% of controls, with a pregnancy rate of 19-71% in the treated patients. Furthermore, seven meta-analyses have concluded that GnRH-a are beneficial and may decrease the risk of POF in survivors. However, controversy still remains regarding the efficiency of GnRH-a in preserving fertility. Since not all the methods involving fertility preservation are unequivocally successful and safe, these young patients deserve to be informed of all the various modalities to minimize gonadal damage and preserve ovarian function and future fertility. Combining several methods for a specific patient may increase the odds for minimally invasive fertility preservation.

Abstract
OBJECTIVE To determine whether concurrent use of GnRH agonists with chemotherapy preserves ovarian function in women with breast cancer who did not use tamoxifen. DESIGN Systematic review and meta-analysis. SETTING University-based hospitals. PATIENT(S) Premenopausal women with breast cancer treated with chemotherapy who did not receive tamoxifen. INTERVENTION(S) Randomization to concurrent GnRH agonists with chemotherapy or chemotherapy alone. MAIN OUTCOME MEASURE(S) Odds ratio (OR) of resumption of menses 1 year or more after chemotherapy. RESULT(S) Searches were conducted in PubMed, Scopus, Cochrane Trials Register, and the National Research Register through March 2014, and all randomized trials that reported resumption of menses 1 year or more after GnRH agonist with chemotherapy or chemotherapy alone among women with breast cancer who did not receive tamoxifen were included. Four studies were analyzed in the meta-analysis and included 252 patients (GnRH agonist with chemotherapy, n=131; chemotherapy alone, n=121). There was no significant difference in the rate of return of menses between the two groups (OR, 1.47; 95% confidence interval [0.60-3.62]). Heterogeneity among the trials was not significant (I2=16.6%). CONCLUSION(S) Concurrent GnRH agonists with chemotherapy may not preserve ovarian function in women with breast cancer. Furthermore, randomized data are limited regarding fertility after concurrent use of GnRH agonists with chemotherapy.

Abstract
Diagnosis of breast cancer in young women poses a threat to fertility. Due to a recent trend of delaying pregnancy, an increasing number of breast cancer patients in reproductive age wish to bear children. Health care providers have the responsibility to know how to manage fertility issues in cancer survivors. Oncofertility counseling is of great importance to many young women diagnosed with cancer and should be managed in a multi-disciplinary background. Most of young breast cancer patients are candidate to receive chemotherapy, which could lead to premature ovarian failure. A baseline evaluation of ovarian reserve may help in considering the different fertility preservation options. The choice of the suitable strategy depends also on age, type of chemotherapy, partner status and patients' motivation. Various options are available, some established such as embryo and oocyte cryopreservation, some still experimental such as ovarian tissue cryopreservation and ovarian suppression with GnRHa during chemotherapy. An early referral to a reproductive specialist should be offered to patients at risk of infertility who are interested in fertility preservation.

Abstract
IVM refers to the maturation of immature oocytes in culture after their recovery from small antral follicles at the stage prior to selection and dominance. IVM requires little or no FSH in vivo and has been proposed as an alternative to conventional IVF, since it reduces the primary adverse effects caused by controlled ovarian stimulation, including the ovarian hyperstimulation syndrome. Moreover, IVM is a promising option for cases for which no standard protocol is suitable, such as FSH resistance, contraindications for ovarian stimulatory drugs, and the need for urgent fertility preservation. Recently, IVM has been used in women with regular cycles and normal ovaries. However, the pregnancy rate following IVM is suboptimal compared with that of conventional IVF, indicating that further studies to optimize the protocol and the culture conditions are warranted.

Abstract
BACKGROUND Current options for female fertility preservation in the face of cytotoxic treatments include embryo, oocyte and ovarian tissue cryopreservation. However these methods are limited by the patient age, status or available timeframe before treatment and they necessitate invasive procedures. Agents which can prevent or attenuate the ovotoxic effects of treatment would provide significant advantages over the existing fertility preservation techniques, and would allow patients to retain their natural fertility without the necessity for costly, invasive and risky procedures. Recent studies have contributed to our understanding of the mechanisms involved in cytotoxicity-induced ovarian follicle loss and highlight a number of agents that may be able to prevent or reduce this loss. METHODS This paper reviews the relevant literature (research articles published in English up to December 2013) on the mechanisms of cytotoxic-induced ovarian damage and the implications for fertility preservation. We present a comprehensive discussion of the potential agents that have been shown to preserve the ovarian follicle reserve in the face of cytotoxic treatments, including an analysis of their respective advantages and risks, and mechanisms of action. RESULTS Multiple molecular pathways are involved in the cellular response to cytotoxic treatments, and specific cellular reactions depend on variables including the drug class and dose, cell type, and cell stage. A number of agents acting on different elements of these pathways have demonstrated potential for preventing or reducing ovarian follicle loss, although in most cases, the studies are still very preliminary. CONCLUSIONS Advances in our understanding of the mechanisms and pathways involved in both cytotoxic ovarian damage and follicle growth and development have opened up new directions for fertility preservation. In order to bring these agents from the lab to the clinic, it will be vital to accurately evaluate the efficacy of each agent and additionally to demonstrate that co-treatment with these agents will not interfere with the anti-cancer activity of the chemotherapy drugs, or produce genetically comprised embryos.

Abstract
This meta-analysis was designed to assess the overall performance of GnRHa in preserving the ovarian function in young women undergoing chemotherapy. Electronic literature databases including Pubmed, MEDLINE, Cochrane library, Embase, CNKI and Wanfang were searched for articles published till November, 2013. The articles written in both Chinese and English were considered. Only randomized controlled trials (RCTs) were selected. Main Outcome Measure was evaluated by assessing the post‑chemotherapy ovarian function. A random-effects model was used to calculate the risk ratio (RR) and associated 95% confidence intervals (95% CI). Out of the eight RCTs including 621 patients, 321 women were treated with GnRHa during chemotherapy, 9.66% of whom suffered premature ovarian failure (POF). On the other hand, 26.67% of the remaining 300 women suffered POF. More women treated without GnRHa experienced post-chemotherapy POF, yielding an RR of 0.45 [chemotherapy plus GnRHa vs. chemotherapy alone, 95% confidence interval (CI) (0.22, 0.92)]. Based on the available studies, GnRHa plays an important role in the prevention of post-chemotherapy POF, but does not exhibit its protective effects in fertility.

Abstract
BACKGROUND The role of temporary ovarian suppression with gonadotropin-releasing hormone analogues (GnRHa) in the prevention of chemotherapy-induced premature ovarian failure (POF) is still controversial. We conducted a systematic review and meta-analysis of randomized trials evaluating the efficacy of GnRHa, given before and during chemotherapy, in the prevention of POF in premenopausal cancer patients. METHODS Studies were retrieved by searching PubMed, Web of Knowledge database and the proceedings of major conferences. We calculated Odds Ratios (OR) and 95% confidence intervals (CIs) for POF from each trial and obtained pooled estimates through the random effects model as suggested by DerSimonian and Laird. RESULTS Nine studies were included in the meta-analysis with 225 events of POF occurring in 765 analyzed patients. The pooled OR estimate indicates a highly significant reduction in the risk of POF (OR=0.43; 95% CI: 0.22-0.84; p=0.013) in patients receiving GnRHa. There was statistically significant heterogeneity among studies (I(2)=55.8%; p=0.012). There was no evidence of publication bias. Subgroups analyses showed that the protective effect of GnRHa against POF was similar in subgroups of patients defined by age and timing of POF assessment, while it was present in breast cancer but unclear in ovarian cancer and lymphoma patients. CONCLUSIONS Our pooled analysis of randomized studies shows that the temporary ovarian suppression induced by GnRHa significantly reduces the risk of chemotherapy-induced POF in young cancer patients.

Abstract
BACKGROUND Gonadotropin-releasing hormone agonists (GnRHa) might play a role in preserving ovarian function in lymphoma patients by inhibiting chemotherapy-induced ovarian follicular damage. However, studies of its clinical efficacy have reported conflicting results. METHOD We conducted a meta-analysis to determine the effect of the preservation of ovarian function by administering GnRHa in young patients with lymphoma undergoing chemotherapy. Seven studies were identified that met inclusion criteria and comprised 434 patients assigned to GnRHa combined chemotherapy or chemotherapy alone. RESULTS The incidence of women with premature ovarian failure (POF) demonstrated a statistically significant difference in favor of the use of GnRHa (OR=0.32, 95% CI 0.13-0.77). In addition, the final level of FSH in the GnRH group was significantly lower than control group. (MD= -11.73, 95% CI,-22.25- -1.20), and the final level of AMH in the GnRH group was significantly higher than control group (MD=0.80; 95% CI, 0.61-0.98). However, there was no statistically significant difference between treatment and the control groups in the incidence of a spontaneous pregnancy (OR=1.11; 95% CI, 0.55-2.26). CONCLUSION This meta-analysis suggests that GnRHa may be effective in protecting ovarian function during chemotherapy in lymphoma patients. More well-designed prospective studies are needed to carry out for further understanding of this topic.

Abstract
STUDY QUESTION Can Sphingosine-1-phosphate (S1P), a ceramide-induced death pathway inhibitor, prevent cyclophosphamide (Cy) or doxorubicin (Doxo) induced apoptotic follicle death in human ovarian xenografts? SUMMARY ANSWER S1P can block human apoptotic follicle death induced by both drugs, which have differing mechanisms of cytotoxicity. WHAT IS KNOWN ALREADY S1P has been shown to decrease the impact of chemotherapy and radiation on germinal vesicle oocytes in animal studies but no human translational data exist. STUDY DESIGN, SIZE, DURATION Experimental human ovarian xenografting to test the in vivo protective effect of S1P on primordial follicle survival in the chemotherapy setting. The data were validated by assessing the same protective effect in the ovaries of xenografted mice in parallel. PARTICIPANTS/MATERIALS, SETTING, METHODS Xenografted mice were treated with Cy (75 mg/kg), Cy+S1P (200 μM), Doxo (10 mg/kg), Doxo+S1P or vehicle only (Control). S1P was administered via continuous infusion using a mini-osmotic pump beginning 24 h prior to and ending 72 h post-chemotherapy. Grafts were then recovered and stained with anti-caspase 3 antibody for the detection of apoptosis in primordial follicles. The percentage of apoptotic to total primordial follicles was calculated in each group. MAIN RESULTS AND THE ROLE OF CHANCE Both Cy and Doxo resulted in a significant increase in apoptotic follicle death in human ovarian xenografts compared with controls (62.0 ± 3.9% versus 25.7 ± 7.4%, P < 0.01 and 76.7 ± 7.4% versus 25.7 ± 7.4%, P < 0.01, respectively). This chemotherapy-induced apoptotic death was reduced both in the Cy+S1P (32.7 ± 4.4%, P < 0.01) and the Doxo+S1P group (27.1 ± 7.6%, P < 0.01) compared with Cy and Doxo groups, respectively. In the Doxo+S1P and Cy+S1P groups, the percentages of apoptotic follicles were similar to those of vehicle-treated controls (P > 0.05). The findings from the ovaries of the severe combined immunodeficient mice mirrored the findings with human tissue. LIMITATIONS, REASONS FOR CAUTION The functionality of the rescued human ovarian follicles needs to be evaluated in future studies though the studies in rodents showed that rescued oocytes can result in healthy offspring. In addition, the impact of S1P on cancer cells should be further studied. WIDER IMPLICATIONS OF THE FINDINGS S1P and its future analogs hold promise for preserving fertility by pharmacological means for patients undergoing chemotherapy. STUDY FUNDING/COMPETING INTEREST(S) This research is supported by NIH's NICHD and NCI (5R01HD053112-06 and 5R21HD061259-02) and the Flemish Foundation for Scientific Research (FWO-Vlaanderen, grant number FWO G0.065.11N10).

Abstract
Approximately 6% of women with breast cancer are diagnosed before the age of 40. Young age is an independent predictor of adverse outcome and most young breast cancer patients receive systemic treatment with chemotherapy, hormonal therapy or both. The loss or impairment of fertility is a potential side effect of antineoplastic treatments. Due to the rising trend to delaying pregnancy in life, an increasing proportion of young cancer patients who are yet to have a pregnancy will face the problem of iatrogenic menopause in the future. The incidence of anticancer-treatment-related ovarian failure depends on the type of chemotherapy regimen administered, the use of tamoxifen and the age of patients. It rises with increasing age, in the range of 22-61% and 61-97% in women aged <40 years and >40 years respectively. Although there is a clear trend to increasing incidence of ovarian failure with the rise in aging, there may be a small proportion of patients who became amenorrhoeic despite the very young age, thus indicating that also individual factors still unknown may affect the probability of treatment-related ovarian failure. A prompt referral of patients to reproductive counseling and a multidisciplinary team including Oncology and Reproductive Units are essential to face the management of fertility issues in cancer patients. Fertility counseling should include a detailed description of all the available techniques to preserve fertility. The main available fertility preservation techniques, standard and experimental, for young breast cancer patients include: temporary ovarian suppression during chemotherapy with gonadotropin-releasing hormone analogues, embryo cryopreservation, cryopreservation of oocytes and cryopreservation of ovarian tissue. Research efforts are still necessary to improve the efficacy and safety of the available fertility preservation strategies as well as an efficient collaboration between oncologists and gynecologists is necessary to improve patients' access to the strategies themselves.
