EUropean REcommendations for female FERtility preservation (EU-REFER): A joint collaboration between oncologists and fertility specialists

Let's talk about sex: consensus guidelines of the GINECOR working group of the Spanish Society of Radiation Oncology: clinical recommendations after pelvic radiotherapy

PURPOSE

The present consensus statement was developed by the GINECOR working group on behalf of the Spanish Society of Radiation Oncology (SEOR). This document addresses sexual health management in patients with gynaecological cancer after pelvic radiotherapy.

METHODS

A modified two-round online Delphi study was conducted, where GINECOR members were surveyed on the diagnosis, treatment, and follow-up of sexual health problems. An expert panel of radiation oncologists, nurses and a gynaecologist participated in the Delphi study to reach a consensus, applying GRADE criteria to establish the level of agreement.

RESULTS

The consensus recommendations cover both diagnosis and treatment, with an emphasis on patient-reported outcome measures (PROMs). They highlight recommendations such as the systematic assessment of genitourinary, gastrointestinal, and sexual symptoms, and the use of several treatments after radiotherapy. Recommendations include pharmacological options like vaginal lubricants and hormone therapy, and mechanical interventions such as vaginal dilators and vibrators. These suggestions stem from both scientific evidence and clinical expertise.

CONCLUSION

This consensus statement describes a comprehensive, multidisciplinary approach developed to address the sexual needs and enhance the quality of life of patients with gynaecological tumours after pelvic radiotherapy. It offers specific recommendations for managing sexual issues, emphasizing the importance of specialized care and regular assessment. The document underscores the significance of proactive, patient-centered sexual health management in gynaecological cancer patients.

Fertility preservation in female cancer patients in Brazil: perceptions and attitudes of infertility specialists

Objective

Fertility preservation is a priority in oncology for female cancer patients. However, there is a lack of communication between infertility specialists and oncologists. This study aimed to evaluate infertility specialists' perceptions and experiences regarding fertility preservation.

Methods

Conduct an online survey to profile infertility specialists. Participants were infertility affiliated with the Brazilian Federation of Gynecology and Obstetrics Associations (FEBRASGO). The specialists received an online survey, which response rate were 30.9%, most of whom were in southern and southeastern. The survey consisted on 14 questions about the infertility specialists' location, techniques in clinical practice, treatment successful rate, patients idea, etc.

Results

The average experience in human reproduction were 15.5 ± 10.2 years (mean ± standard deviation, range 1-40). Among reproductive-aged female cancer patients recommended for fertility preservation, 60.3 ± 28.8% (range 10-100%) underwent preservation procedures. Main barriers were cost (41%), oncologists' knowledge or acceptance (35%) and accessibility (9%). Most infertility specialists (58%) considered 40 years the limit for fertility preservation. Leukemia, lymphoma, breast and ovarian cancers were prioritized for fertility preservation, while lung, thyroid, gastric, and brain cancers were less relevant.

Conclusion

This is the first Brazilian study about infertility specialists' perceptions on oncology patients access to fertility preservation. These patients primarily receive treatment in the public health system, while infertility specialists mainly work in the private healthcare. This healthcare mode is currently fragmented, but integrating these experts is enhancing patient access to fertility preservation. Studies on this topic are still warranted.

Fertility Preservation in Adolescents and Young Adults With Cancer: A Case-Based Review

Adolescent and young adult (AYA) oncology patients are unique in many aspects of their care; fertility preservation (FP) is one of the most complex to address. In addition to the newly diagnosed AYA patient, there are growing numbers of AYA survivors of childhood cancer who present with concerns about their fertility. Emerging independence, emotional and intellectual growth, and development of an adult mindset are hallmarks of the AYA population; these transitions heighten the intrinsic medical, social, and financial challenges of a cancer diagnosis. FP is extraordinarily important in AYA oncology and can be addressed in many ways: experimental options as well as standard of care, with key differences on the basis of pubertal development, cancer diagnosis, and urgency of cancer-directed therapy. Options exist both at diagnosis and throughout the survivorship journey. It is imperative that oncologists recognize the challenges in this age group, as well as opportunities to pursue FP. The field has evolved significantly in the past 25 years and will continue to evolve as we incorporate more immune-based and targeted therapies into our treatment regimens. This case-based review will explore opportunities to preserve fertility in this unique patient population.

Increasing access to fertility preservation for women with breast cancer: protocol for a stepped-wedge cluster randomized trial in France

BACKGROUND

With the increase in the number of long-term survivors, interest is shifting from cancer survival to life and quality of life after cancer. These include consequences of long-term side effects of treatment, such as gonadotoxicity. Fertility preservation is becoming increasingly important in cancer management. International recommendations agree on the need to inform patients prior to treatments about the risk of fertility impairment and refer them to specialized centers to discuss fertility preservation. However, the literature reveals suboptimal access to fertility preservation on an international scale, and particularly in France, making information for patients and oncologists a potential lever for action. Our overall goal is to improve access to fertility preservation consultations for women with breast cancer through the development and evaluation of a combined intervention targeting the access and diffusion of information for these patients and brief training for oncologists.

METHODS

Firstly, we will improve existing information tools and create brief training content for oncologists using a qualitative, iterative, user-centred and participatory approach (objective 1). We will then use these tools in a combined intervention to conduct a stepped-wedge cluster randomized trial (objective 2) including 750 women aged 18 to 40 newly treated with chemotherapy for breast cancer at one of the 6 participating centers. As the primary outcome of the trial will be the access to fertility preservation counselling before and after using the combined intervention (brochures and brief training for oncologists), we will compare the rate of fertility preservation consultations between the usual care and intervention phases using linear regression models. Finally, we will analyse our approach using a context-sensitive implementation analysis and provide key elements for transferability to other contexts in France (objective 3).

DISCUSSION

We expect to observe an increase in access to fertility preservation consultations as a result of the combined intervention. Particular attention will be paid to the effect of this intervention on socially disadvantaged women, who are known to be at greater risk of inappropriate treatment. The user-centred design principles and participatory approaches used to optimize the acceptability, usability and feasibility of the combined intervention will likely enhance its impact, diffusion and sustainability.

Oncofertility and Pregnancy in Adolescent and Young Adult Cancers: Physicians' Knowledge and Preferences in India

PURPOSE

The treatment outcomes of adolescent and young adult (AYA) cancers have improved with advanced oncology care. Hence, fertility preservation (FP) and post-therapy pregnancies (PTPs) become vital issues.

MATERIALS AND METHODS

An online survey link with 17 questions regarding oncofertility and PTPs was circulated among oncologists to assess the knowledge, understand the oncofertility care patterns, and seek suggestions to improve oncofertility services.

RESULTS

The median age of 179 respondents, predominantly medical oncologists (68.7%), was 37 years (IQR, 10; range, 29-74), working in academic centers (39%) having a median experience of 4 years (IQR, 4; range, 1-42); 23 (12.8%) had dedicated AYA cancer units. Although a quarter (19%-24%) of respondents discussed fertility issues in >90% of AYA patients with cancer, only a tenth (8%-11%) refer >90% for FP, with significantly higher (P < .05) discussions and referrals in males and by more experienced oncologists (P < .05). Forty-six (25.6%) were not well versed with international guidelines for FP. Most (122, 68.1%) oncologists knew about the referral path for semen cryopreservation; however, only 46% were knowledgeable about additional complex procedures. One hundred and ten (61.5%) oncologists never or rarely altered the systemic treatment for FP. Prominent barriers to FP were ignorance, lack of collaboration, and fear of delaying cancer treatment. Lead thrust areas identified to improve FP practices are education, and enhanced and affordable access to FP facilities. Seventy-four (41.3%) respondents knew about international guidelines for PTPs; however, only half (20%) of them often monitored fertility outcomes in survivors. Oncologists have conflicting opinions and uncertainties regarding pregnancy safety, assisted reproductive techniques, breastfeeding, and pregnancy outcomes among survivors.

CONCLUSION

Oncologists are uncertain about the guidelines, FP practices, referral pathways, and PTPs. Multipronged approaches to improve awareness and provision for affordable oncofertility facilities are needed to enhance AYA cancer outcomes in India, which will be applicable to other low- and middle-income countries too.

Disparities in fertility preservation use among adolescent and young adult women with cancer

PURPOSE

Women face multiple barriers to fertility preservation after cancer diagnosis, but few studies have examined disparities in use of these services.

METHODS

Women aged 15-39 years diagnosed with cancer during 2004-2015 were identified from the North Carolina Central Cancer Registry and linked to the Society for Assisted Reproductive Technology Clinic Outcomes Reporting System. Women who cryopreserved oocytes or embryos for fertility preservation (n = 96) were compared to women who received gonadotoxic treatment but did not use fertility preservation (n = 7964). Conditional logistic and log-binomial regression were used to estimate odds ratios (ORs) or prevalence ratios (PRs) and 95% confidence intervals (CIs).

RESULTS

Few adolescent and young adult women with cancer in our study (1.2%) used fertility preservation. In multivariable regression, women less likely to use fertility preservation were older at diagnosis (ages 25-29 vs. 35-39: OR = 6.27, 95% CI: 3.35, 11.73); non-Hispanic Black (vs. non-Hispanic White: PR = 0.44, 95% CI: 0.24, 0.79); and parous at diagnosis (vs. nulliparous: PR = 0.24, 95% CI: 0.13, 0.45); or lived in census tracts that were non-urban (vs. urban: PR = 0.12, 95% CI: 0.04, 0.37) or of lower socioeconomic status (quintiles 1-3 vs. quintiles 4 and 5: PR = 0.39, 95% CI: 0.25, 0.61).

CONCLUSIONS

Women with cancer who were older, non-Hispanic Black, parous, or living in areas that were non-urban or of lower socioeconomic position were less likely to use fertility preservation.

IMPLICATIONS FOR CANCER SURVIVORS

Clinical and policy interventions are needed to ensure equitable access to fertility services among women facing cancer treatment-related infertility.

Oncofertility: Treatment options from bench to bedside

In recent years, there has been continuous improvement in the treatment and diagnosis of cancer, which has led to a significant improvement in the survival rate of cancer patients. Treatments that include chemotherapy, radiotherapy, surgery, or combined therapy have several side effects that may lead to premature ovarian insufficiency in females or substantial male germ cell loss. Reproductive biologists recommend that all patients who are diagnosed with a malignant tumor must undergo a consultation for fertility protection and preservation. In this review, we discuss the background knowledge, methods, and options for fertility preservation and how these new strategies help oncologists, surgeons, pediatricians, and hematologists, conserve fertility and be aware of the concepts, methods, and importance of fertility guards. This review may aid in the advancement of novel personalized methods for fertility preservation according to patients' conditions.

Thoughts about fertility among female adolescents and young adults with cancer: a qualitative study

PURPOSE

Nine hundred female adolescents and young adults (AYAs) aged 15-39 are diagnosed with cancer in Denmark annually. Advances in cancer therapy have led to increased long-term survival; however, a serious side effect of cancer therapy is reduced fertility. The aim of our study was to explore the thoughts about fertility among female AYAs with cancer.

METHODS

Our study was conducted from September 2020 to March 2021 at the Copenhagen University Hospital, Rigshospitalet. Inclusion criteria were female AYAs with cancer aged 18-39. Twelve individual, semi-structured, qualitative interviews were performed with female AYAs with cancer (20-35 years). Data were analysed using thematic analysis.

RESULTS

Four main themes were found: (1) the female AYAs held on to a hope of having children in the future; (2) the female AYAs experienced time pressure and waiting time as a sprint as well as a marathon; (3) the female AYAs faced existential and ethical choices about survival and family formation; and (4) the female AYAs felt a loss of control of their bodies.

CONCLUSION

Our study contributes with knowledge on how important holding on to the hope of children in the future is among female AYAs with cancer. Meanwhile, they are frustrated by the rushed decision on fertility preservation at diagnosis. The female AYAs also have existential and ethical concerns related to the choice of cancer therapy and fertility preservation. Finally, they suffer from altered body image, loss of femininity, and body control due to hormone therapy.

Disparities in the use of assisted reproductive technologies after breast cancer: a population-based study

PURPOSE

Equitable access to oncofertility services is a key component of cancer survivorship care, but factors affecting access and use remain understudied.

METHODS

To describe disparities in assisted reproductive technology (ART) use among women with breast cancer in California, we conducted a population-based cohort study using linked oncology, ART, and demographic data. We identified women age 18-45 years diagnosed with invasive breast cancer between 2000 and 2015. The primary outcome was ART use-including oocyte/embryo cryopreservation or embryo transfer-after cancer diagnosis. We used log-binomial regression to estimate prevalence ratios (PRs) and 95% confidence intervals (CIs) to identify factors associated with ART use.

RESULTS

Among 36,468 women with invasive breast cancer, 206 (0.56%) used ART. Women significantly less likely to use ART were age 36-45 years at diagnosis (vs. 18-35 years: PR = 0.17, 95% CI 0.13-0.22); non-Hispanic Black or Hispanic (vs. non-Hispanic White: PR = 0.31, 95% CI 0.21-0.46); had at least one child (vs. no children: adjusted PR [aPR] = 0.39, 95% CI 0.25-0.60); or lived in non-urban areas (vs. urban: aPR = 0.28, 95% CI 0.10-0.75), whereas women more likely to use ART lived in high-SES areas (vs. low-/middle-SES areas: aPR = 2.93, 95% CI 2.04-4.20) or had private insurance (vs. public/other insurance: aPR = 2.95, 95% CI 1.59-5.49).

CONCLUSION

Women with breast cancer who are socially or economically disadvantaged, or who already had a child, are substantially less likely to use ART after diagnosis. The implementation of policies or programs targeting more equitable access to fertility services for women with cancer is warranted.

Time to cancer treatment and reproductive outcomes after fertility preservation among adolescent and young adult women with cancer

BACKGROUND

Fertility preservation (FP) may be underused after cancer diagnosis because of uncertainty around delays to cancer treatment and subsequent reproductive success.

METHODS

Women aged 15 to 39 years diagnosed with cancer between 2004 and 2015 were identified from the North Carolina Central Cancer Registry. Use of assisted reproductive technology (ART) after cancer diagnosis between 2004 and 2018 (including FP) was assessed through linkage to the Society for Assisted Reproductive Technology. Linear regression was used to examine time to cancer treatment among women who did (n = 95) or did not (n = 469) use FP. Modified Poisson regression was used to estimate risk ratios (RRs) and 95% CIs for pregnancy and birth based on timing of ART initiation relative to cancer treatment (n = 18 initiated before treatment for FP vs n = 26 initiated after treatment without FP).

RESULTS

The median time to cancer treatment was 9 to 33 days longer among women who used FP compared with women who did not, matched on clinical factors. Women who initiated ART before cancer treatment may be more likely to have a live birth given pregnancy compared with women who initiated ART after cancer treatment (age-adjusted RR, 1.47; 95% CI, 0.98-2.23), though this may be affected by the more frequent use of gestational carriers in the former group (47% vs 20% of transfer cycles, respectively).

CONCLUSIONS

FP delayed gonadotoxic cancer treatment by up to 4.5 weeks, a delay that would not be expected to alter prognosis for many women. Further study of the use of gestational carriers in cancer populations is warranted to better understand its effect on reproductive outcomes.

Outcomes after assisted reproductive technology in women with cancer: a systematic review and meta-analysis

STUDY QUESTION

What are the associations between a history of cancer and outcomes after ART?

SUMMARY ANSWER

Compared to women without cancer, on average, women with cancer had a lower return for embryo transfer and a lower likelihood of clinical pregnancy and live birth after ART.

WHAT IS KNOWN ALREADY

Small, single-institution studies have suggested that cancer and its treatment may negatively affect ART outcomes.

STUDY DESIGN, SIZE, DURATION

We conducted a systematic review with meta-analysis of studies comparing ART outcomes between women with and without cancer. PubMed, Embase and Scopus were searched for original, English-language studies published up to June 2021.

PARTICIPANTS/MATERIALS, SETTING, METHODS

Inclusion criteria required reporting of ART outcomes after controlled ovarian stimulation (COS) among women with a history of cancer compared to women without cancer who used ART for any indication. Outcomes of interest ranged from duration of COS to likelihood of live birth after embryo transfer. Random-effects meta-analysis was used to calculate mean differences and odds ratios (ORs) with 95% CIs and 95% prediction intervals (PIs). We assessed heterogeneity by age-adjustment, referent group indication for ART, study location and among women with breast cancer and women who initiated ART before cancer treatment. We used visual inspection, Egger's test and the trim-and-fill method to assess funnel plot asymmetry.

MAIN RESULTS AND THE ROLE OF CHANCE

Of 6094 unique records identified, 42 studies met inclusion criteria, representing a median per study of 58 women with cancer (interquartile range (IQR) = 159) and 114 women without cancer (IQR = 348). Compared to women without cancer, on average, women with cancer had a lower return for embryo transfer (OR: 0.22; 95% CI: 0.07, 0.74; 95% PI: 0.00, 64.98); lower likelihood of clinical pregnancy (OR: 0.51; 95% CI: 0.35, 0.73; 95% PI: 0.19, 1.35); and lower likelihood of live birth (OR: 0.56; 95% CI: 0.38, 0.83; 95% PI: 0.19, 1.69). Substantial among-study heterogeneity was observed for COS duration, gonadotropin dose, cycle cancellation, total oocytes and mature oocytes. Fertilization percentage showed less heterogeneity, but study-specific estimates were imprecise. Similarly, number of embryos showed less heterogeneity, and most studies estimated minimal differences by cancer history. Funnel plot asymmetry was observed for estradiol peak and oocyte maturation percentage.

LIMITATIONS, REASONS FOR CAUTION

Appreciable confounding is possible in 11 studies that lacked adequate control for group differences in age, and among-study heterogeneity was observed for most outcomes. Lack of data limited our ability to assess how cancer clinical factors (e.g. cancers other than breast, cancer stage and treatment) and ART cycle characteristics (e.g. fresh versus frozen embryo transfers and use of gestational carriers) may affect outcomes.

WIDER IMPLICATIONS OF THE FINDINGS

Women with cancer may be less likely to achieve pregnancy and live birth after embryo transfer. Further examination of reproductive outcomes and sources of heterogeneity among studies is warranted to improve evidence of the expected success of ART after a cancer diagnosis.

Fertility preservation in women with benign gynaecological conditions

Although a wealth of data has been published regarding fertility preservation (FP) in women with malignant diseases who receive gonadotoxic treatment, the role of FP in non-malignant conditions has been studied to a much lesser extent. These include benign haematological, autoimmune, and genetic disorders, as well as a multitude of benign gynaecological conditions (BGCs) that may compromise ovarian reserve and/or reproductive potential due to pathogenic mechanisms or as a result of medical or surgical treatments. Alongside accumulating data that document the reproductive potential of cryopreserved oocytes and ovarian tissue, there is potential interest in FP for women with BGCs at risk of infertility; however, there are currently insufficient data about FP in women with BGCs to develop guidelines for clinical practice. The purpose of this article is to appraise the available evidence regarding FP for BGC and discuss potential strategies for FP based on estimated ovarian impairment and on short-term and long-term reproductive goals of patients. Cost-effectiveness considerations and patients' perspectives will also be discussed.

A predictive model of the effect of therapeutic radiation on the human ovary

Radiation to the female pelvis as part of treatment for cancer predisposes young women to develop Premature Ovarian Insufficiency (POI). As the human female is born with their full complement of non-growing follicles which decline in an exponential fashion until the menopause, the age at which POI occurs is dependent on the age of the patient at treatment and the dose received by the ovary. A model that predicts the age at which POI occurs for a known dose at a known age will aid counselling patients on their fertility risk. Patients deemed to be at high risk of POI may be considered to be good candidates for established fertility preservation techniques. An updated and externally validated model of the age-related decline in human ovarian reserve was combined with the best available estimate of the median lethal dose LD₅₀ for the human ovary. Using known age at diagnosis and posited radiotherapy treatment plan to estimate the dose to the least-affected ovary, we use an age-related model of the decline in ovarian reserve to generate a personalized age prediction of premature ovarian insufficiency. Our algorithm is available as an online calculator which graphs model outputs to inform discussions around survivor fertility. We report four example cases across different ages and diagnoses, each with two carefully designed photon and proton treatment plans. The treatment options are compared in terms of remaining fertile lifespan for the survivor. International oncology guidelines now mandate the consideration of later fertility when reviewing treatment options for children diagnosed with cancer. Our calculator (https://sites.cs.st-andrews.ac.uk/radiosensitivity), and the underlying algorithm and models, allow detailed predictions of the impact of various radiotherapy plans on fertility. These patient-specific data enhance pre-treatment discussions around post-treatment fertility and fertility preservation.

Fertility after Cancer: Risks and Successes

The incidence of cancer in reproductive-aged women is 7%, but, despite the increased number of cancer cases, advances in early diagnosis and treatment have raised the survival rate. Furthermore, in the last four decades, there has been a rising trend of delaying childbearing. There has been an increasing number of couples referred to Reproductive Medicine Centers for infertility problems after one partner has been treated for cancer. In these cases, the main cause of reduced fertility derives from treatments. In this review, we describe the effects and the risks of chemotherapy, radiotherapy, and surgery in women with cancer, and we will focus on available fertility preservation techniques and their efficacy in terms of success in pregnancy and live birth rates.

A practical survey of fertility-preservation treatments in the startup phase in Japan

AIM

The actual status of fertility preservation treatments in the startup phase in Japan was investigated as a basis for discussing future directions.

METHODS

This study was conducted as "Research project to promote support of children and parenting 2016" which was supported by Ministry of Health in Japan with the approval of the institutional review board at St. Marianna University. Subjects of the survey were facilities registered with the Japan Society of Obstetrics and Gynecology as fertility preservation facilities, and facilities belonging to the Japan Association of Private Assisted Reproductive Technology Clinics and Laboratories. We provided questionnaires to survey both the medical care system and cases for which fertility preservation was implemented between 2006 and 2016.

RESULTS

Responses were obtained from 68 facilities (of the 64, 59 [92.2%] responded to the questionnaire and 9 clinics cooperated). Many facilities limited the cryopreservation of oocytes and ovaries to patients 40-41 years old and the use of eggs to patients 44-45 years old. In the patient survey, 812 cases of oocyte cryopreservation and 201 cases of ovarian tissue cryopreservation were performed during study period. Breast cancer was the most indicated disease, with oocyte cryopreservation in the late 30s and ovarian tissue cryopreservation in the early 30s. Very few babies were born from fertility preservation, and no live birth cases of ovarian tissue cryopreservation were identified.

CONCLUSIONS

Even from the early days, fertility preservation was implemented according to certain standards in Japan, but was characterized by a large variety of facilities.

Protective effects of a SIRT1 inhibitor on primordial follicle activation and growth induced by cyclophosphamide: insights from a bovine in vitro folliculogenesis system

Purpose

Although oncological advances have improved survival rates of female cancer patients, they often suffer a reduced fertility due to treatment side effects. In the present study, we evaluated the potential fertoprotective effects of the specific inhibitor of SIRT1, EX-527, on the gonadotoxic action exerted by cyclophosphamide (CPM) on loss of primordial follicles (PFs).

Methods

The effects of the CPM metabolite phosphoramide mustard (PM) on follicle activation, growth and viability and the protective action of EX-527 against PM effects were evaluated on bovine ovarian cortical strips in vitro cultured for 1 or 6 days. To understand whether PFs exposed to PM plus EX-527 were able to activate and grow to the secondary stage after suspension of the treatment, strips cultured for 3 days in PM plus EX-527 for 3 days were transferred to plain medium until day 6. Follicle growth and health were evaluated through histology and viability assay at a confocal microscope. In order to investigate the molecular pathways underlying the ovarian response to PM in the presence of EX-527, we analysed the protein level of SIRT1, HuR, PARP1 and SOD2 after 1 day of in vitro culture.

Results

We found that (1) PM, the main CPM active metabolite, promotes PF activation; (2) the ovarian stress response induced by PM includes a SIRT1-dependent pathway; and (3) EX-527 reduces PF activation and growth induced by PM.

Conclusion

SIRT1 can represent a candidate molecule to be targeted to protect ovarian follicles from alkylating agents and EX-527 could represent a potential fertoprotective agent for cancer patients.

GnRH Analogues as a Co-Treatment to Therapy in Women of Reproductive Age with Cancer and Fertility Preservation

In this review, we analyzed existing literature regarding the use of Gonadotropin-releasing Hormone (GnRH) analogues (agonists, antagonists) as a co-treatment to chemotherapy and radiotherapy. There is a growing interest in their application as a prophylaxis to gonadotoxicity caused by chemotherapy and/or radiotherapy due to their ovarian suppressive effects, making them a potential option to treat infertility caused by such chemotherapy and/or radiotherapy. They could be used in conjunction with other fertility preservation options to synergistically maximize their effects. GnRH analogues may be a valuable prophylactic agent against chemotherapeutic infertility by inhibiting rapid cellular turnover on growing follicles that contain types of cells unintentionally targeted during anti-cancer treatments. These could create a prepubertal-like effect in adult women, limiting the gonadotoxicity to the lower levels that young girls have. The use of GnRH agonists was found to be effective in hematological and breast cancer treatment whereas for ovarian endometrial and cervical cancers the evidence is still limited. Studies on GnRH antagonists, as well as the combination of both agonists and antagonists, were limited. GnRH antagonists have a similar protective effect to that of agonists as they preserve or at least alleviate the follicle degradation during chemo-radiation treatment. Their use may be preferred in cases where treatment is imminent (as their effects are almost immediate) and whenever the GnRH agonist-induced flare-up effect may be contra-indicated. The combination treatment of agonists and antagonists has primarily been studied in animal models so far, especially rats. Factors that may play a role in determining their efficacy as a chemoprotective agent that limits gonadal damage, include the type and stage of cancer, the use of alkylating agents, age of patient and prior ovarian reserve. The data for the use of GnRH antagonist alone or in combination with GnRH agonist is still very limited. Moreover, studies evaluating the impact of this treatment on the ovarian reserve as measured by Anti-Müllerian Hormone (AMH) levels are still sparse. Further studies with strict criteria regarding ovarian reserve and fertility outcomes are needed to confirm or reject their role as a gonadal protecting agent during chemo-radiation treatments.

Assessment of female fertility preservation in Auvergne 3 years after implementation of the PREFERA platform (PREservation FERtilité Auvergne)

INTRODUCTION

Fertility preservation (FP) in patients with cancer or pathology at risk of gonadotoxicity is now according to legislation, an integral part of the treatment protocol. for this reason, clinical-biological platforms have emerged with the aim of developing and improving this practice, such as the PREFERA platform (PREservation FERtilité Auvergne) MATERIAL ET METHOD: This is an observational cohort study to evaluate female fertility preservation activity in Auvergne at the AMP-CECOS center of the Clermont-Ferrand University Hospital from March 2013 to March 2019. This period covering 3 years before and after the creation of PREFERA in 2015.

RESULTS

205 patients were referred for fertility preservation consultations, including 77 before the platform was set up and 128 after, corresponding to an increase of 66%. 190 patients (92.7%) referred were eligible for FP, of whom 169 (88.9%) received treatment. Thirty-nine patients underwent oocyte vitrification before the platform was set up and 74 after (+89.7%), twenty patients underwent ovarian cortex freezing before the platform was set up and 27 after (+35%). Only 54 patients (26.2%) were seen for follow-up with an increased number of consultations following the implementation of PREFERA. (8% vs 33%, p<0.001).

CONCLUSION

Creation of the PREFERA platform facilitated patient access and management of fertility preservation procedures. However, at the regional level, it is necessary to continue to raise awareness of fertility issues, particularly in the context of post-cancer follow-up, both among patients and health professionals.

Minimal residual disease detection by multicolor flow cytometry in cryopreserved ovarian tissue from leukemia patients

Background

Cryopreservation of ovarian tissue is a fertility-preservation option for women before gonadotoxic treatments. However, cryopreserved ovarian tissue transplantation must be performed with caution in women with malignancies that may metastasize to the ovaries. For this purpose, detecting minimal residual disease (MRD) in the ovarian cortex using sensitive methods is a crucial step. We developed an automated ovarian tissue dissociation method to obtain ovarian cell suspensions.

Results

We assessed MRD by multicolor flow cytometry (MFC) in cryopreserved ovarian cortex of 15 leukemia patients: 6 with B-cell acute lymphoblastic leukemia (B-ALL), 2 with T-cell acute lymphoblastic leukemia (T-ALL) and 7 with acute myeloid leukemia (AML). Ovarian MRD was positive in 5 of the 15 leukemia patients (one T-ALL and 4 AML). No B-ALL patient was positive by MFC. Quantitative reverse-transcribed polymerase chain reaction was performed when a molecular marker was available, and confirmed the MFC results for 3 patients tested. Xenografts into immunodeficient mice were also performed with ovarian cortical tissue from 10 leukemia patients, with no evidence of leukemic cells after the 6-month grafting period.

Conclusions

In conclusion, this is the first study using MFC to detect MRD in ovarian cortical tissue from acute leukemia patients. MFC has been accepted in clinical practice for its ease of use, the large number of parameters available simultaneously, and high throughput analysis. We demonstrate here that MFC is a reliable method to detect MRD in cryopreserved ovarian tissue, with a view to controlling the oncological risk before ovarian tissue transplantation in leukemia patients.

Ovarian tissue and oocyte cryopreservation prior to iatrogenic premature ovarian insufficiency

Gonadotoxic treatments like chemotherapy or radiotherapy and ovarian surgery may result in an accelerated depletion of the ovarian reserve and subsequent premature ovarian insufficiency. Important determinants of this severe risk that require fertility preservation strategies are patient age, ovarian reserve, type of treatment, and administered dose. Oocytes and ovarian tissue can both be cryopreserved, with encouraging results in terms of pregnancy and live birth rates according to recent publications. Moreover, since ovarian tissue transplantation also results in long-term endocrine resumption, it represents a potential future therapeutic option for complete ovarian function restoration in patients with premature ovarian insufficiency.

Disparities in Female Pediatric, Adolescent and Young Adult Oncofertility: A Needs Assessment

Advancements in cancer screening and implementation of targeted treatments have significantly improved survival rates to 85% for pediatric and AYA survivors. Greater than 75% of survivors will live to experience the long-term adverse outcomes of cancer therapies, termed late effects (LE), that disrupt quality of life (QoL). Infertility and poor reproductive outcomes are significant disruptors of QoL in survivorship, affecting 12-88% of survivors who receive at-risk therapies. To mitigate risk, fertility preservation (FP) counseling is recommended as standard of care prior to gonadotoxic therapy. However, disparities in FP counseling, implementation of FP interventions, and screening for gynecologic late effects in survivorship persist. Barriers to care include a lack of provider and patient knowledge of the safety and breadth of current FP options, misconceptions about the duration of time required to implement FP therapies, cost, and health care team bias. Developing strategies to address barriers and implement established guidelines are necessary to ensure equity and improve quality of care across populations.

Oncofertility Knowledge and Communication: Comparison Between Medical and Surgical Oncologists and Breast Cancer Patients in Academic Chinese Centers

Background: As cancer has become a major public health issue in China, fertility preservation remains limited despite the wide application of Assisted Reproductive Technology (ART) throughout the country.

Objective: This study aimed to identify gaps in knowledge and communication as well as referrals in the previous year regarding oncofertility among medical and surgical oncologists and breast cancer patients (BCPs) in Chinese academic settings to target areas of needed improvement.

Materials and Methods: A WeChat online questionnaire was designed, distributed, and compared between medical and surgical oncology specialists and reproductive age BCPs in academic teaching settings in Shanghai.

Results: Sixty-one medical and surgical oncologists and 125 BCPs responded to the survey. 63.3% of oncologists were familiar with the term “oncofertility” compared to 25.6% of BCPs (p < 0.001). Oncologists were more likely to correctly know the costs associated with treatment (59.0 vs. 32.0%, p < 0.001); patient did not have to be married to undergo oncofertility treatment (50.8 vs. 24.8%, p < 0.001). Both oncologists and BCPs were similarly unlikely to know when patients could utilize cryopreserved tissue in the future (37.7 vs. 22.2%, p = 0.056). While oncologists reported they discussed all oncofertility options (41.0%) and offered psychological counseling (98.4%), significantly fewer BCPs reported receiving information on all options and offered counseling (3.2%, p < 0.001 and 85.6%, p < 0.01). Knowledge of oncofertility was the most important predictor for providing and receiving counseling from oncologists [OR = 6.44 (95% CI = 1.59–26.1, p = 0.009] and BCPs (OR = 3.73 95% CI: = 1.36–10.2, p = 0.011). Overall, 57.4% of oncologists referred <10 patients and none referred more than 25 patients in the past year.

Conclusion: Data suggests a significant knowledge gap and ineffective communication/comprehension exists between academic Chinese oncologists and BCPs. Continued education and raised awareness are needed to optimize utilization of oncofertility services in China.

Decisional Regret in Female Oncofertility Decision Making-An Integrative Narrative Review

It is well established that fertility is an important issue for young women with cancer at reproductive age, as many have not initiated or completed their parenthood goals when diagnosed. Because cancer treatments may impair fertility, women face fertility decisions that are often complex and surrounded by uncertainty. This may put patients at risk for psychological distress and the experience of regret regarding decisions made at diagnosis, which may be associated with a negative impact on women's QoL. This narrative review addresses current knowledge about decisional regret regarding fertility preservation decisions in adult female cancer patients at reproductive age. Electronic searches were conducted on Pubmed database for articles published in English from 1 January 2000 to 1 July 2021 that assessed decisional regret following fertility decisions in young women diagnosed at childbearing age. Of the 96 articles identified, nine provided information on decisional regret regarding fertility decisions. Studies reported that, overall, decisional regret regarding oncofertility decisions was low. Factors associated with the experience of decisional regret were patients' perceived quality and satisfaction with fertility counseling received, the decision to undergo fertility preservation, desire for children and decisional conflict. Health providers should be aware of the factors that are potentially modifiable and prone to improvement in order to reduce decisional regret. All efforts should be made to improve availability of and access to tailored high quality fertility counseling and fertility preservation. Given the growing evidence that decision aids (DAs) are effective in increasing knowledge and reducing decisional conflict and regret, their use in a routine and timely manner to complement fertility counseling is recommended.

Fertility and breast cancer: A literature review of counseling, preservation options and outcomes

Fertility preservation is an important issue in breast cancer patients undergoing oncological treatment. Fertility counseling is a crucial need given the physical and psychological stress experienced by patients. Cryopreservation of mature oocytes is currently the standard fertility-preserving procedure. Other options such as ovarian tissue preservation or gonadal protection during chemotherapy are still experimental, but have proven effectiveness. Prompt referral to a fertility unit is highly recommended in order to ensure quality of care. In this article, we focus on the different strategies to preserve fertility in breast cancer patients, assessing also the safety of pregnancy and breastfeeding after cancer. A systemic literature review was performed for research articles published in English in PubMed, or as abstracts from the European Society for Medical Oncology (ESMO), San Antonio Breast Cancer Symposium (SABCS) and American Society of Clinical Oncology (ASCO) annual meetings, using the search terms "breast cancer" and "fertility".

Fertility preservation and management of pregnancy in melanoma patients requiring systemic therapy

Melanoma is one of the most common cancers in adolescents and adults at fertile age, especially in women. With novel and more effective systemic therapies that began to profoundly change the dismal outcome of melanoma by prolonging overall survival, the wish for fertility preservation or even parenthood has to be considered for a growing portion of melanoma patients-from the patients' as well as from the physicians' perspective. The dual blockade of the mitogen-activated protein kinase pathway by B-Raf proto-oncogene serine/threonine kinase and mitogen-activated protein kinase inhibitors and the immune checkpoint inhibition by anti-programmed cell death protein 1 and anti-cytotoxic T-lymphocyte-associated protein-4 monoclonal antibodies constitute the current standard systemic approaches to combat locally advanced or metastatic melanoma. Here, the preclinical data and clinical evidence of these systemic therapies are reviewed in terms of their potential gonadotoxicity, teratogenicity, embryotoxicity and fetotoxicity. Recommendations for routine fertility and contraception counseling of melanoma patients at fertile age are provided in line with interdisciplinary recommendations for the diagnostic work-up of these patients and for fertility-protective measures. Differentiated recommendations for the systemic therapy in both the adjuvant and the advanced, metastatic treatment situation are given. In addition, the challenges of pregnancy during systemic melanoma therapy are discussed.

Controlled ovarian stimulation outcomes of fertility preservation procedures in newly diagnosed breast cancer patients: a retrospective study from a single-tertiary-IVF centre

The aim of this study was to evaluate the effectiveness of controlled ovarian stimulation (COS) using the letrozole-supplemented stimulation protocol in breast cancer (BC) patients prior to their cancer treatment. Sixty-one BC patients (Stages 0-3) who were referred to a university IVF unit for fertility preservation (FP) and underwent embryo and/or oocyte cryopreservation between 2008 - 2020 were included in this retrospective study. Time intervals between breast surgery and initial fertility consultation (IFC)/completion of FP procedures were evaluated. COS outcomes were assessed and compared between the early follicular phase (EFP) and the random-start (RS) protocols. The patients' mean age was 33.3 ± 4.9 years. The mean time interval between breast surgery and IFC was 20.6 ± 11 (day, mean ± SD) and from IFC to completion of FP procedure was 14.7 ± 5.3. Overall, 9.1 ± 5.9 mature oocytes were obtained, with a peak serum oestradiol level of 388 ± 358 pg/mL. The number of oocytes obtained (11.5 ± 9.3 vs. 10.9 ± 6.9, p = .9) and maturation rates (84.3 ± 17.5% vs. 89.2 ± 11.7, p = .5) were not statistically different between the EPF and RS protocols. The study results support that oocyte or embryo freezing can be performed effectively in a limited time period with letrozole-supplemented COS protocols before the initiation of oncological treatments in breast cancer patients.Impact statementWhat is already known on this subject? Currently, embryo and oocyte freezing are considered the most established fertility preservation (FP) methods for newly diagnosed cancer patients.What do the results of this study add? This study reports the COS outcomes of newly diagnosed breast cancer patients for FP over a period of twelve years from a single IVF unit. The results support that a considerable number of oocytes can be harvested with letrozole-supplemented COS protocol, which appears to be an effective protocol for BC patients.What are the implications of these findings for clinical practice and/or further research? There is a need for additional studies evaluating long-term follow-up of patients with their pregnancy outcomes.

Hot Topics on Fertility Preservation for Women and Girls-Current Research, Knowledge Gaps, and Future Possibilities

Fertility preservation is a novel clinical discipline aiming to protect the fertility potential of young adults and children at risk of infertility. The field is evolving quickly, enriched by advances in assisted reproductive technologies and cryopreservation methods, in addition to surgical developments. The best-characterized target group for fertility preservation is the patient population diagnosed with cancer at a young age since the bulk of the data indicates that the gonadotoxicity inherent to most cancer treatments induces iatrogenic infertility. Since improvements in cancer therapy have resulted in increasing numbers of long-term survivors, survivorship issues and the negative impact of infertility on the quality of life have come to the front line. These facts are reflected in an increasing number of scientific publications referring to clinical medicine and research in the field of fertility preservation. Cryopreservation of gametes, embryos, and gonadal tissue has achieved quality standards for clinical use, with the retrieval of gonadal tissue for cryopreservation being currently the only method feasible in prepubertal children. Additionally, the indications for fertility preservation beyond cancer are also increasing since a number of benign diseases and chronic conditions either require gonadotoxic treatments or are associated with premature follicle depletion. There are many remaining challenges, and current research encompasses clinical health care and caring sciences, ethics, societal, epidemiological, experimental studies, etc.

Live birth rate after use of cryopreserved oocytes or embryos at the time of cancer diagnosis in female survivors: a retrospective study of ten years of experience

PURPOSE

The aim of this study was to evaluate the outcomes of frozen oocytes or embryos cryopreserved after controlled ovarian stimulation (COS) or in vitro maturation (IVM) for female cancer patients who underwent a fertility preservation (FP) prior to gonadotoxic therapy.

METHODS

A retrospective cohort study from 2009 to December 2017 was conducted. Among the 667 female cancer patients who underwent oocytes or embryos cryopreservation for FP, 40 (6%) have returned to the fertility clinic between 2011 and 2019 to use their frozen material after being cured. We compared these thaw cycles outcomes according to the techniques used at the time of cryopreservation.

RESULTS

Among the 40 women cancer survivors who used their cryopreserved material, thirty patients have benefited from at least one embryo transfer. Ten patients did not have an embryo transfer since the oocytes did not survive after the thawing process or because no embryo was obtained after fertilization. We related three live births following FP using IVM (two from frozen oocytes and one after embryo cryopreservation). Five live births were obtained when COS was performed at the time of FP (one from frozen oocytes and four after embryo cryopreservation).

CONCLUSIONS

Our preliminary results, although they are obtained in a small sample, are encouraging and show that different FP techniques can be used in female cancer patients and lead to live births. IVM is one of the options available that does not delay the start of chemotherapy or if ovarian stimulation using gonadotropins is contraindicated.

How Do Young Women with Cancer Experience Oncofertility Counselling during Cancer Treatment? A Qualitative, Single Centre Study at a Danish Tertiary Hospital

BACKGROUND

Adolescents and young adults (AYAs) with cancer are at risk of therapy-induced infertility. The importance of initial and specialized fertility counselling to this patient group is undisputed. Despite international guidelines, oncofertility counselling is still inadequate. The purpose of this study was to examine how female AYA cancer patients and survivors experienced initial and specialized oncofertility counselling, and to present their specific suggestions on how to improve the oncofertility counselling.

METHODS

Twelve individual semi-structured interviews were performed with AYAs aged 20-35 with cancer or who were survivors. Participants were recruited via a youth support centre and social organization for AYAs with cancer. Data was analysed using thematic analysis.

RESULTS

Three main themes were found: Support is needed for navigating the fertility information jungle; The doctor's approach determines the content of the patient consultation; Inadequate and worrying information causes mistrust and frustration.

CONCLUSION

Results indicate a continuing problem regarding insufficient oncofertility counselling to AYAs with cancer. To ensure adequate and uniform information, especially in the initial oncofertility counselling, national guidelines for oncology specialists are suggested including multidisciplinary effort and collaboration between oncology and fertility specialists in mind. In addition, participants suggest focus on communication skills.

Construction and cryopreservation of an artificial ovary in cancer patients as an element of cancer therapy and a promising approach to fertility restoration

The proportion of cancer patients that survive is increasing because of improvements in cancer therapy. However, some cancer treatments, such as chemo- and radio-therapies, can cause considerable damage to reproductive function. The issue of fertility is paramount for women of childbearing age once they are cured from cancer. For those patients with prepubertal or haematogenous cancer, the possibilities of conventional fertility treatments, such as oocyte or embryo cryopreservation and transplantation, are limited. Moreover, ovarian tissue cryopreservation as an alternative to fertility preservation has limitations, with a risk of re-implanting malignant cells in patients who have recovered from potentially fatal malignant disease. One possible way to restore fertility in these patients is to mimic artificially the function of the natural organ, the ovary, by grafting isolated follicles embedded in a biological scaffold to their native environment. Construction and cryopreservation of an artificial ovary might offer a safer alternative option to restore fertility for those who cannot benefit from traditional fertility preservation techniques. This review considers the protocols for constructing an artificial ovary, summarises advances in the field with potential clinical application, and discusses future trends for cryopreservation of these artificial constructions.

Adipose tissue-derived stem cells protect the primordial follicle pool from both direct follicle death and abnormal activation after ovarian tissue transplantation

PURPOSE

To investigate whether adipose tissue-derived stem cells (ASCs) protect the primordial follicle pool, not only by decreasing direct follicle loss but also by modulating follicle activation pathways.

METHODS

Twenty nude mice were grafted with frozen-thawed human ovarian tissue from 5 patients. Ten mice underwent standard ovarian tissue transplantation (OT group), while the remaining ten were transplanted with ASCs and ovarian tissue (2-step/ASCs+OT group). Ovarian grafts were retrieved on days 3 (n = 5) and 10 (n = 5). Analyses included histology (follicle count and classification), immunohistochemistry (c-caspase-3 for apoptosis and LC3B for autophagy), and immunofluorescence (FOXO1 for PI3K/Akt activation and YAP for Hippo pathway disruption). Subcellular localization was determined in primordial follicles on high-resolution images using structured illumination microscopy.

RESULTS

The ASCs+OT group showed significantly higher follicle density than the OT group (p = 0.01). Significantly increased follicle atresia (p < 0.001) and apoptosis (p = 0.001) were observed only in the OT group. In primordial follicles, there was a significant shift in FOXO1 to a cytoplasmic localization in the OT group on days 3 (p = 0.01) and 10 (p = 0.03), indicating follicle activation, while the ASCs+OT group and non-grafted controls maintained nuclear localization, indicating quiescence. Hippo pathway disruption was encountered in primordial follicles irrespective of transplantation, with nuclear YAP localized in their granulosa cells.

CONCLUSION

We demonstrate that ASCs exert positive effects on the ovarian reserve, not only by protecting primordial follicles from direct death but also by maintaining their quiescence through modulation of the PI3K/Akt pathway.

[Oncofertility and breast cancer at Montpellier University Hospital: Retrospective analysis of patients management since 2011]

OBJECTIVE

Five to 7% of breast cancers affect women under 40 years old. The survival of these patients has been improved thanks to therapeutic advances, often to the detriment of their fertility. The objective of this study is to evaluate the activity of oncofertility and the future of young women with breast cancer managed at the Montpellier University Hospital.

METHODS

This is a retrospective study including women aged from 18 to 43 years-old diagnosed with breast cancer and referred in oncofertility consultation at the Montpellier University Hospital between July 2011 and December 2018.

RESULTS

190 patients were eligible, three refused to participate to the study, hence 187 patients were included. We estimate that only 33% of young breast cancer patients potentially eligible for fertility preservation (FP) benefited from an oncofertility consultation in our region. Of these 187 patients, 58 (31%) underwent ovarian stimulation for oocyte or embryo vitrification. They were significantly younger: 32.9 vs 34.6 years old (P=0.01) and had fewer invaded lymph nodes. A total of 66 cycles were achieved and 11.4 oocytes or 3 embryos were vitrified per patient. The reuse rate was 3.6% with 91% of post cancer pregnancies being spontaneous.

CONCLUSION

The oncofertility care network seems effective at the regional level. Enhancing health professionals' awareness and creating a regional register could improve our long-term follow-up.

Preservation of fertility in female: Indications, available options, and current status in Saudi Arabia

Refinement of therapies continues to improve the prognosis and survival of cancer patients. However, women of reproductive age face a risk of premature ovarian failure due to the gonadotoxicity of aggressive oncological treatment, which may also be used to treat other nonmalignant disorders. Development of cryobiology and assisted reproduction has allowed fertility preservation, which is increasingly requested, and can also aid fertility in iatrogenic and noniatrogenic conditions. Established protocols including embryo and oocyte freezing are only performed for adult women; however, ovarian tissue cryopreservation is an approach that can also assist prepubertal girls. Medical fertility cryopreservation for females has been recently legalized in Saudi Arabia. However, prior to implementing the service in clinical practice in Saudi Arabia, guidelines on patient selection criteria and adequate staff training are essential. Moreover, worldwide registry data and the findings of long-term studies involving many patients on the safety of ovarian tissue freezing are required to conclusively establish medical fertility cryopreservation as a safe procedure. Progress can be achieved in oncofertility by improving and optimizing techniques that include immature oocyte growth and maturation and artificial ovary development.

Efficacy and Safety of Controlled Ovarian Stimulation With or Without Letrozole Co-administration for Fertility Preservation: A Systematic Review and Meta-Analysis

Background: The co-administration of letrozole during controlled ovarian stimulation (COS) with gonadotropins is used to limit the potentially harmful effects of a supra-physiological rise in estrogen levels on hormone-sensitive cancers. However, the efficacy and safety of adding letrozole to COS remain debated.

Methods: This is a systematic review and meta-analysis of published studies that compared the efficacy and safety of COS with co-administration of letrozole vs. COS without letrozole in all patient populations. A secondary analysis was done including only the studies in breast cancer patients. The primary efficacy endpoint was the number of retrieved mature Metaphase II (MII) oocytes. Secondary efficacy and safety endpoints were total number of oocytes, maturation rate, fertilization rate, number of cryopreserved embryos, peak estradiol levels, progesterone levels, and total gonadotropin dose. Data for each endpoint were reported and analyzed thorough mean ratio (MR) with 95% confidence interval (CI).

Results: A total of 11 records were selected including 2,121 patients (990 patients underwent COS with letrozole and 1,131 COS without letrozole). The addition of letrozole to COS did not have any negative effect on the number of mature oocytes collected (MR = 1.00, 95% CI = 0.87–1.16; P = 0.967) and the other efficacy endpoints. COS with letrozole was associated with significantly decreased peak estradiol levels (MR = 0.28, 95% CI = 0.24–0.32; P < 0.001). Similar results were observed in the secondary analysis including only breast cancer patients.

Conclusions: These findings are reassuring on the efficacy and safety of COS with gonadotropins and letrozole and are particularly important for fertility preservation in women with hormone-sensitive cancers.

Fertility preservation does not delay the initiation of chemotherapy in breast cancer patients treated with adjuvant or neo-adjuvant chemotherapy

PURPOSE

To investigate whether fertility preservation (FP) in adult women diagnosed with breast cancer (BC) may impact the time interval between diagnosis and start of chemotherapy in an adjuvant or neo-adjuvant setting.

METHODS

Retrospective cohort study of breast cancer patients diagnosed between January 2012 and December 2017 undergoing FP at a tertiary-care academic fertility centre before neo-adjuvant (NAC) or adjuvant chemotherapy (AC), and matched control breast cancer patients who had no FP. FP interventions included oocyte vitrification following ovarian stimulation or after in-vitro maturation (IVM) of immature oocytes, and/or ovarian tissue cryopreservation. Controls from the patient database of the affiliated Breast Cancer Clinic were matched for tumour characteristics and type of treatment. Time intervals between cancer diagnosis and the start of chemotherapy were analysed.

RESULTS

Fifty-nine BC patients underwent FP: 29 received NAC and 30 received AC. The average interval between diagnosis and chemotherapy in BC patients with NAC was 28.5 days (27.3 (range: 14.0-44.0) days in cases and 29.6 (range: 14.0-62.0) days in controls (NS)); this interval was 58.9 days in BC patients with AC (57.2 (range: 36.0-106.0) days in cases and 60.7 (range: 31.0-105.0) days in controls (NS)).

CONCLUSION

Fertility preservation does not delay the start of chemotherapy in breast cancer patients.

Results of a Phase I-II Study on Laser Therapy for Vaginal Side Effects after Radiotherapy for Cancer of Uterine Cervix or Endometrium

Women who have previously received radiotherapy (RT) for gynecologic cancer often suffer from vaginal fibrosis and stenosis. The success of “non-ablative” laser therapy for postmenopausal vaginal atrophy has led to the idea of testing the laser in patients submitted to RT. In this prospective observational study, we selected patients who underwent pelvic RT followed by vaginal laser treatment. We scheduled three treatment sessions (at T0–T1–T2) and three controls (at T1–T2–T3) one month apart. The follow-up (at T4) was carried out six months after the last treatment. Vaginal Health Index (VHI) and vaginal length were evaluated. Sexual function was assessed through Female Sexual Function Index (FSFI). Overall, 43 patients with severe vaginal shortening, atrophy and stenosis was enrolled and treated with intravaginal non-ablative CO₂ laser. We observed a progressive increase in vaginal length of 9% (p = 0.03) at T2 and 28% (p < 0.0001) at T3; effects were maintained at T4 (p < 0.0001). After the first application VHI showed a significant improvement of 57% at T3 (p < 0.0001). The results were maintained at T4 (p < 0.0001). No changes were found in FSFI. All procedures were well tolerated. In conclusion, laser therapy improved vaginal length and VHI in women undergoing pelvic RT; prospective studies are needed.

Impact of COVID-19 Pandemic on Gynecological Oncology Care: Glimpse into Association of Gynecological Oncologists of India (AGOI) Perspective

PURPOSE

The notorious COVID 19 pandemic has caused rapid and drastic changes in cancer care worldwide in 2020. This online survey aims to assess the extent to which the pandemic has affected cancer care in gynecological oncology amongst members of the Association of Gynecological Oncologists of India (AGOI), a registered professional society founded in 1991.

METHODS

We developed and administered a cross-sectional, flash survey to members of AGOI in the first week of April 2020. Data were analyzed using Microsoft Office Excel 2016. Results were expressed as percentages of total responses excluding blank or unattended response. Overall theme-specific responses were described as a spectrum of findings, and related inferences were drawn.

RESULTS

Among approached practitioners, 90 responded to the survey, more than 80% were practicing consultants, and more than 50% from academic institutions. The results of the study showed that the ongoing pandemic had severely affected gynecological oncology practice and care amongst all respondents. There were modifications in diagnostic pathways, interventions, and follow-ups across all organ sites. There was a near-unanimous opinion on the use of general safety measures to combat the virus and to use complete PPEs in a high-risk situation. There were mixed responses to alternative educational activities, especially using electronic technology and distant learning methods. There was optimism among respondents with regards to the current situation normalizing in 3-6 months.

CONCLUSION

This study documents the pandemic affected scenario of gynecological cancer care and perceptions of Gynecological Oncologists in India. A significant effect on all aspects of cancer care was observed. Technological learning methods, both for patient care and educational activities, were being adopted by many respondents.

[Access to fertility preservation for adolescents and young adults aged 15 to 24 years with cancers in Auvergne, France]

INTRODUCTION

Cancers of adolescents and young adults have particular epidemiological specificities. The improvement in their survival should be accompanied by an increased consideration of the treatments' side effects, among which the potential decrease in fertility. The objective of the study was to describe the access to fertility preservation of these patients at the University Hospital of Clermont-Ferrand over a period of 3 years.

METHODS

During this retrospective descriptive study, various socio-demographic and clinical data were collected.

RESULTS

One hundred and fifty new cases of cancers were diagnosed in patients aged 15 to 24 years. Forty-four percent received at least one fertility consultation, 29 % for girls and 58 % for boys (P<0.001). The number of cases that did not result in fertility preservation was significantly higher for girls than boys (P=0.005). Fertility preservation was mainly achieved by cryopreservation of ovarian tissue in female adolescents, ovocytes in young women and sperm in boys.

DISCUSSION

We observed sex disparities in access to fertility preservation. Despite the existence of recommendations, progress remains to be made. The establishment of clinico-biological platforms should allow a better awareness of patients and professionals, and thus promote access to fertility preservation techniques for young patients with cancer.

Key recommendations for high-quality female oncofertility care based on international clinical practice guidelines

RESEARCH QUESTION

Which guideline-based key recommendations can be selected for high-quality female oncofertility care?

DESIGN

The Delphi method was used to select a set of key recommendations for female oncofertility care. First, recommendations from (inter)national clinical practice guidelines were selected in four domains: risk communication, referral, counselling and decision-making. Thereafter, they were scored, per domain, on their importance for high-quality oncofertility care by a multidisciplinary, oncofertility expert panel, consisting of patients, referrers and counsellors, in two Delphi rounds. Finally, the selected key recommendations were presented for approval in a third round. Differences in perspectives between subgroups of the expert panel were analysed.

RESULTS

A panel of 86 experts was asked to select key recommendations for high-quality oncofertility care. Eleven key recommendations were selected. Key recommendations in the domains risk communication and referral focused on information provision and offering referral to a reproductive specialist to female cancer patients. With the counselling domain, key recommendations focused on all aspects of counselling, including different methods, safety, pros and cons. In the decision-making domain, key recommendations focused on shared decision-making and supporting the decision with written information. The final set of key recommendations was approved by 91% of the experts. Differences in perspectives were found between subgroups. Patients found recommendations on decision-making and information provision more important.

CONCLUSION

A set of 11 key recommendations for high-quality female oncofertility care was selected by a multidisciplinary expert panel. The involvement of the perspectives of patients, referrers and counsellors led to this valid, acceptable and credible set of key recommendations.

Effect of Surgical Specialty on Management of Adnexal Masses in Children and Adolescents: An 8-Year Single-Center Review

STUDY OBJECTIVE

Children with adnexal masses might be managed by pediatric surgeons, urologists or gynecologists, with the potential for different management strategies between specialties. In this study we compared ovarian conservation rates and surgical approach for adnexal masses in children and adolescents managed either by pediatric surgeons/urologists or gynecologists at a tertiary care institution.

DESIGN

Retrospective cohort review.

SETTING

Tertiary pediatric and adult university hospital.

PARTICIPANTS

Patients younger than 18 years of age with an adnexal mass managed surgically with removal of histologically confirmed ovarian or fallopian tube tissue from 2008 to 2015.

INTERVENTIONS

Laparoscopic or open procedure for adnexal mass.

MAIN OUTCOME MEASURES

The primary outcome was rate of ovarian conservation relative to surgical specialty. The secondary outcome was surgical approach relative to surgical specialty.

RESULTS

Forty-eight patients underwent surgery for adnexal masses; 26 (54%) under pediatric surgery/urology and 22 (46%) under gynecology care. Laparoscopy was performed in 5 (19%) pediatric and 19 (86%) gynecology cases (P = .000006). Of 24 patients older than 12 years of age with a benign tumor, 10 (42%) underwent procedures resulting in loss of an ovary with or without fallopian tube; 8 of these (80%) were under pediatric care. Of the remaining 14 (58%) who underwent ovarian conserving surgery, 12 (80%) were under gynecology care (P = .0027).

CONCLUSION

Patients with a benign tumor were significantly more likely to undergo ovary-preserving surgery under gynecology care than under pediatric surgery/urology care. A multidisciplinary team approach involving gynecology and pediatric surgical specialties would be valuable in assessing the merits of ablative or conservative surgery in each case.

Chemotherapy Associated Ovarian Failure

As the incidence of malignancies in young adults is increasing, fertility preservation in cancer survivors arises as a major concern. Especially among female cancer patients, pregnancy rates are estimated to be 40% lower compared to women of the same age. Nowadays oncologists are to be preoccupied not only with their patients' successful treatment, but also with the maintenance of the potential of the latter to conceive and obtain children. Chemotherapy associated ovarian failure (COF), refers to disruption of ovarian function both as an endocrine gland and as a reproductive organ, due to previous exposure to chemotherapy agents. Although the underlying mechanism is not fully understood, it is supposed that chemotherapy agents may induce either DNA damage of premature ovarian follicle or early activation and apoptosis of them, resulting into early exhaustion of available follicle deposit. Various chemotherapy agents have been associated with COF with the highest incidence being reported for patients undergoing combination regimens. Although a variety of alternatives in order to maintain ovarian function and fertility in female cancer survivors are available, adequately established practices to do so are lacking. Thus, it is of major importance to investigate further and collect sufficient evidence, aiming to guide patients and physicians in everyday clinical practice.

Counseling young women with early breast cancer on fertility preservation

PURPOSE

Women with early-stage breast cancer may still have a future child wish, while chemotherapy may impair fertility. To pursue on fertility preservation shortly after breast cancer diagnosis is complex. This review holds a critical reflection on all topics that need to be counseled to give them the opportunity to make a well-informed decision before starting any oncological treatment.

METHODS

A comprehensive literature review was performed on papers published in English language on breast cancer in young women, risk of chemotherapy-induced infertility, fertility preservation techniques, impact of possible mutation carriership, and future pregnancy outcome.

RESULTS

Below 40 years of age, the risk of permanent chemotherapy-induced ovarian function failure is approximately 20%, where taxanes do not significantly add to this risk. Overall, 23% of reported women who performed fertility preservation by cryopreserving oocytes or embryos returned for embryo transfer. Of these, 40% gave live birth. Both fertility preservation in women diagnosed with breast cancer and pregnancy after treatment seem safe with respect to breast cancer survival. Women who have a genetic predisposition for breast cancer like BRCA gene mutation should also be informed about the possibility of pre-implantation genetic diagnosis.

CONCLUSIONS

Women with an early stage of breast cancer and a possible future child wish should be referred to an expertise center in breast cancer, fertility preservation, and genetics in this complex decision-making process, shortly after diagnosis.

Preserving fertility in female patients with hematological malignancies: a multidisciplinary oncofertility approach

Oncofertility is a new interdisciplinary field at the intersection of oncology and reproductive medicine that expands fertility options for young cancer patients. The most common forms of hematological malignancies that occur in girls and young women and therefore necessitate oncofertility care are acute lymphocytic leukemia, acute myeloid leukemia, non-Hodgkin's lymphoma, and Hodgkin's lymphoma. Aggressive gonadotoxic anticancer regimens including alkylating chemotherapy and total body irradiation are used often in treating girls and young women with hematological malignancies. The risks of gonadotoxicity and subsequent iatrogenic premature ovarian insufficiency and fertility loss depend mainly on the type and stage of the disease, dose of anticancer therapy as well as the age of the patient at the beginning of treatment. To avoid or at least mitigate the devastating complications of anticancer therapy-induced gonadotoxicity, effective and comprehensive strategies that integrate different options for preserving and restoring fertility ranging from established to experimental strategies should be offered before, during, and after chemotherapy or radiotherapy. A multidisciplinary approach that involves strong coordination and collaboration between hemato-oncologists, gynecologists, reproductive biologists, research scientists, and patient navigators is essential to guarantee high standard of care.
