Fertility-related services in pediatric oncology across the cancer continuum: a clinic overview

Expansion of the Fertility Preservation Program to All Newly Diagnosed Prepubertal Patients with Cancer at a Pediatric Hospital

Background: As the majority of pediatric patients with cancer survive their disease, generating a population of over 500,000 childhood cancer survivors in the United States, it is imperative to minimize the lifelong consequences of treatment, which include temporary or permanent infertility caused by certain cancer treatments. A fertility consultation at diagnosis can provide patients and families with the opportunity to be informed regarding the likelihood of gonadal dysfunction and to consider fertility preservation. Method: After our pediatric hospital started to offer tissue cryopreservation, we initiated this evidence-based interventional quality improvement project. Our primary aim was to ensure that all newly diagnosed prepubertal patients with cancer who met the criteria for fertility tissue preservation were correctly identified and offered an educational consultation and preservation. Results: Between July 15, 2022 and October 30, 2022, 54 patients' treatment plans were evaluated to determine treatment-related infertility risk using the Oncofertility Consortium Pediatric Initiative Network's Risk Assessment tool. Fifteen patients were at a high level of significantly increased risk and 13 were eligible for consultation. Seven (46%) patients and their families received a consultation. Initiation of treatment before referral was the primary reason for lack of consultation. Six of seven patients receiving consultation (86%) elected to undergo preservation. Preservation procedures did not cause a delay in starting treatment for those patients. Discussion: A fertility preservation program with established policies and processes can increase the likelihood that prepubertal patients at high risk for infertility are correctly identified, educated, and offered preservation.

Contraceptive methods and fertility testing in young adult survivors of childhood cancer

PURPOSE

Reproductive health is important, but often neglected in cancer survivorship care. This study explored contraceptive use and factors associated with fertility testing among young adult survivors of childhood cancer in Germany.

METHODS

Young adult survivors of childhood cancer were identified through the German Childhood Cancer Registry and completed a mailed survey. Survivors were queried regarding contraceptive use, reproductive goals, uncertainty about fertility, and completion or interest in fertility testing. Multivariable stepwise logistic regression models were used to calculate Odds Ratios (OR) and 95% confidence intervals (CI) as a means of identifying factors associated with completion of and interest in fertility testing.

RESULTS

Survivors (N = 472; 57.8% female; aged 23.3 ± 1.5 years, and 14.9 ± 5.0 years from diagnosis), reported high rates of contraceptive use, including 61.2% using a single method, 30.6% dual methods, and 8.1% no/less effective methods. Few survivors had completed fertility testing (13.0%), although 58.8% were interested. Having been diagnosed during adolescence (OR = 2.66, 95%CI: 1.39-5.09), greater uncertainty about fertility (OR = 1.16, 95%CI: 1.03-1.31), and use of dual contraceptive methods (OR = 1.94, 95%CI: 1.02-3.69) were associated with having completed fertility testing. Factors associated with interest in fertility testing included goals of wanting to have children (OR = 7.76, 95%CI: 3.01-20.04) and greater uncertainty about fertility (OR = 1.19 95%CI: 1.06-1.33).

CONCLUSION

In this sample of young adults who survived childhood cancer, most reported contraceptive use. Few survivors had completed fertility testing, although more than half were interested. Interventions are needed to address potential barriers to fertility testing and help survivors manage fertility-related uncertainty.

Fertility Preservation Practices at Pediatric Oncology Institutions in the United States: A Report From the Children's Oncology Group

PURPOSE

Fertility discussions are an integral part of comprehensive care for pediatric, adolescent, and young adult patients newly diagnosed with cancer and are supported by national guidelines. Current institutional practices are poorly understood.

METHODS

A cross-sectional survey was distributed to 220 Children's Oncology Group member institutions regarding fertility discussion practices. Descriptive statistics were calculated for all variables. The association between specific practices and selected outcomes on the basis of sex was examined via multivariable logistic regression.

RESULTS

One hundred forty-four programs (65.5%) returned surveys. Of these, 65 (45.1%) reported routine discussions of fertility with all female patients and 55 (38.5%) all male patients (P = .25). Ninety-two (63.8%) reported no specific criteria for offering females fertility preservation (FP), compared with 40 (27.7%) for males (P < .001). Program characteristics associated with fertility discussions included reproductive endocrinology and infertility on site (females odds ratio [OR], 2.1; 95% CI, 1.0 to 4.3), discussion documentation mandate (females OR, 2.3; 95% CI, 1.0 to 5.5; males OR, 3.5; 95% CI, 1.4 to 8.7), and cumulative institution-based FP infrastructure (which included [1] routine practice of documentation, [2] template for documentation, [3] mandate for documentation, and [4] availability of FP navigation; females OR, 1.6; 95% CI, 1.1 to 2.3; males OR, 2.3; 95% CI, 1.6 to 3.4). Utilization of practices unsupported by guidelines included offering sperm banking after treatment initiation (39/135 programs; 28.9%), gonadotropin-releasing hormone analogs for ovarian suppression/FP (75/144 programs; 52.1%), ovarian tissue cryopreservation at diagnosis for patients with leukemia (19/64 programs; 29.7%), and testicular tissue cryopreservation (23/138 programs; 16.7%) not part of a clinical trial.

CONCLUSION

Despite recommended guidelines, fertility discussions with patients/families before treatment initiation are not routine at Children's Oncology Group institutions. Standard criteria to determine which options should be offered to patients are more common for males than females.

The evolution of fertility preservation care models in a large pediatric cancer and blood disorders center

BACKGROUND

Children and adolescents who receive gonadotoxic treatments are at risk for future infertility. While there is a growing focus on integrating fertility preservation (FP) within pediatric cancer and blood disorder centers, wide variations in care models and methods exist across institutions. The purpose of this work is to describe the evolution of FP care models within a large pediatric hematology/oncology center.

METHODS

Models of care and associated timeframes are described, including a pre-FP program model, establishment of a formal FP program, integration of nurse navigators, and the addition of FP consult stratification based on urgency (urgent/nonurgent). The number of patient consults within each model, patient sex, diagnosis (oncologic/hematologic), and consult timing (pre-gonadotoxic treatment/posttreatment completion) were abstracted from the clinical database.

RESULTS

The number of annual consults increased from 24 during the pre-FP program model (2015) to 181 during the current care model (2020). Over time, the proportion of consults for females and patients with nonmalignant hematologic disorders increased. Patient stratification reduced the proportion of consults needing to be completed urgently from 75% at the advent of the FP program to 49% in the current model.

CONCLUSIONS

The evolution of care models within our FP program allowed for growth in the number of consults completed, expansion of services to more patients with nonmalignant hematologic disorders, and more consults for female patients. Nurse navigators play a critical role in care facilitating referrals, coordination, and patient education. Urgency stratification has allowed FP team members to manage increasing FP-related encounters.

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.

Fertility preservation in children and young adults with cancer

PURPOSE OF REVIEW

The issue of fertility preservation has become increasingly relevant as survival rates of children with cancer exceeds 80% at 5 years. Fertility preservation options are being utilized alongside less gonadotoxic therapeutic regimens in the treatment of these patients. The purpose of this review is to summarize the recent advances in fertility preservation in the pediatric, adolescent, and young adult population.

RECENT FINDINGS

Education research involves both patient and provider; to increase understanding on both sides for improved adoption of techniques and higher rates of posttreatment fertility. Basic science research, specific to the pediatric population, has worked to further understanding of protective techniques and cryopreserved tissue transfer. Research on the techniques of preservation confirms the safety of surgical gonadal (ovarian and testicular) tissue retrieval for cryopreservation but a viable pathway for testicular tissue utilization, as it has for ovarian, has yet to be realized. Outcomes may be improving but it is apparent that robust registries are necessary to track patients long-term. Possibly the largest advancement in the recent past are group efforts, such as by PanCareLIFE, to create guidelines for these issues using larger cohorts and registries than were available.

SUMMARY

Current research implies the need for the development of a national strategy to ensure that pediatric patients undergoing gonadotoxic regimens are educated, alongside their family, about fertility options and outcomes thereafter.

Psychosexual Care of Adolescent and Young Adult (AYA) Cancer Survivors

Adolescent and young adult (AYA) survivors of cancer have diverse psychosocial and medical needs, including those related to fertility and sexual health. Much of the focus of care around issues such as fertility and sexual health tends to be filtered through a biomedical lens. However, it is essential that health care providers assess and support AYA survivors using a biopsychosocial and contextual framework to ensure the most comprehensive and accurate understanding of AYA survivor needs, especially those related to psychosexual health. A trusting relationship between the multi-disciplinary medical team and the AYA survivor that allows for open discussion about the physical and psychosocial components of sexual health is key to providing best care and outcomes.

Documentation of Oncofertility Communication in Adolescents and Young Adults with Cancer: A Retrospective Analysis

Background: Increasing numbers of adolescents and young adults with cancer (AYACs) are surviving long term, highlighting the importance of effective oncofertility communication. We undertook this study to understand documentation of fertility discussions with AYACs, what options are offered, and how this differs for AYACs on treatment compared with those post-treatment. Methods: We reviewed the documentation of fertility discussions with 122 AYACs treated between 2000 and 2020: 72 AYACs on treatment and 50 AYACs at least 3 years post-treatment ("late effects" cohort). Results: Diagnoses were split evenly between hematological and solid tumor diagnoses, and biological sex. Seventy-five percent of patients were diagnosed and treated by the AYAC team and 25% by the pediatric team. Median age at diagnosis was 19 years (range 4-24) for on-treatment patients and 16 years (range 3-25) for late effects patients. Fertility was discussed with 93% of on-treatment patients and 48% of late effects patients. Seventy-nine percent of on-treatment patients and 48% of late effects patients pursued a pre-treatment fertility preservation option. Post-treatment, 84% of late effects patients had a discussion and 57% pursued an option. Only four patients across both cohorts underwent oocyte or ovarian tissue cryopreservation. Those referred to specialist reproductive medicine clinics had more detailed documentation about fertility discussions. Nurse-led late effects clinics had a key role in facilitating post-treatment discussions. Conclusions: It is important to communicate oncofertility options to AYACs repeatedly throughout treatment. Referral to specialist oncofertility services and adequate information for both sexes is important pre-treatment, and can be facilitated post-treatment by a late effects service.

Predictive factors for fertility preservation in pediatric and adolescent girls with planned gonadotoxic treatment

PURPOSE

To characterize female pediatric and adolescent patients seen for fertility preservation consultation at an academic medical center and to describe the association between demographic or clinical factors and the use of fertility preservation treatment (FPT).

METHODS

This is a retrospective chart analysis of female pediatric and adolescent patients seen for fertility preservation consultation at an academic fertility center over a 14-year period from 2005 to 2019.

RESULTS

One hundred six females aged 3-21 years were seen for fertility preservation consultation with a mean age of 16.6 years. Diagnoses included hematologic malignancies (41.5%), gynecologic malignancies (9.4%), other malignancies (31.1%), non-malignant hematologic disease (14.2%), and non-malignant conditions (3.8%). Overall, 64.2% of subjects pursued fertility preservation, including oocyte cryopreservation (35.8%) and ovarian tissue cryopreservation (23.6%). Overall, age, minority race, diagnosis, time since diagnosis, and median household income were not significantly associated with odds of completing an FPT procedure. Among all patients, those who underwent gonadotoxic therapy prior to consultation had a lower odds of receiving FPT (OR= 0.24, 95% CI 0.10-0.55). Among patients without chemotherapy exposure, no factors were associated with FPT.

CONCLUSIONS

Among pediatric and adolescent patients at an academic center undergoing a fertility preservation consultation, there were no socioeconomic or clinical barriers to FPT use in those who had not yet undergone gonadotoxic therapy. The only factor that was negatively associated with odds of pursuing FPT was prior chemotherapy exposure.

Fertility preservation in childhood and adolescent female tumor survivors

OBJECTIVE

To assess the proportion of female childhood and adolescent tumor survivors who could benefit from oocyte cryopreservation.

DESIGN

Case series of female childhood and adolescent tumor survivors referred for fertility counseling.

SETTING

A referral cancer center and an infertility unit of an academic hospital.

PATIENT(S)

Young female childhood and adolescent tumor survivors who received gonadotoxic treatments.

INTERVENTION(S)

Patients were prescribed tests of ovarian reserve and a personalized counseling was given. Oocyte cryopreservation was considered in subjects aged ≥18 years who were diagnosed with diminished ovarian reserve (DOR) (antimüllerian hormone level <2 ng/mL or total antral follicle count ≤10).

MAIN OUTCOME MEASURE(S)

Rate of women with DOR who stored their oocytes.

RESULT(S)

Ninety out of 126 evaluated women completed the assessments. We documented preserved ovarian reserve, DOR, and premature ovarian insufficiency in 36 (40%), 35 (39%), and 19 (21%) cases, respectively. Overall, 13 subjects with DOR were eligible for oocyte cryostorage, of whom 9 (69%) underwent the procedure. Considering the whole cohort of evaluated young women (n = 90), the rate of those who had egg freezing was 10%. Finally, nine women started seeking pregnancy after the counseling (six with DOR), and seven of them became pregnant. When the data were analyzed separately according to most gonadotoxic treatments, considerable differences emerged but the evidence did not support the idea that counseling should be restricted to particular subgroups of women.

CONCLUSION(S)

Ovarian reserve impairment is common in female childhood and adolescent tumor survivors. Postcancer oocyte cryopreservation may be part of the armamentarium of fertility preservation options.

A View from the past into our collective future: the oncofertility consortium vision statement

Purpose

Today, male and female adult and pediatric cancer patients, individuals transitioning between gender identities, and other individuals facing health extending but fertility limiting treatments can look forward to a fertile future. This is, in part, due to the work of members associated with the Oncofertility Consortium.

Methods

The Oncofertility Consortium is an international, interdisciplinary initiative originally designed to explore the urgent unmet need associated with the reproductive future of cancer survivors. As the strategies for fertility management were invented, developed or applied, the individuals for who the program offered hope, similarly expanded. As a community of practice, Consortium participants share information in an open and rapid manner to addresses the complex health care and quality-of-life issues of cancer, transgender and other patients. To ensure that the organization remains contemporary to the needs of the community, the field designed a fully inclusive mechanism for strategic planning and here present the findings of this process.

Results

This interprofessional network of medical specialists, scientists, and scholars in the law, medical ethics, religious studies and other disciplines associated with human interventions, explore the relationships between health, disease, survivorship, treatment, gender and reproductive longevity.

Conclusion

The goals are to continually integrate the best science in the service of the needs of patients and build a community of care that is ready for the challenges of the field in the future.

"Looking at future cancer survivors, give them a roadmap": addressing fertility and family-building topics in post-treatment cancer survivorship care

PURPOSE

Fertility is an important issue among adolescent and young adult female (AYA-F) cancer survivors. This study examined AYA-F survivors' unmet needs and recommendations for care to address fertility/family-building in post-treatment survivorship.

METHODS

Semi-structured interviews (45-60 min) explored themes related to fertility and family-building after cancer. Coding categories were derived based on grounded theory methods. Themes were identified through an iterative process of coding and review.

RESULTS

Participants (N = 25) averaged 29 years old (SD = 6.2; range, 15-39) were primarily White and well educated, and averaged 5.81 years post-treatment (SD = 5.43); 32% had undergone fertility preservation (pre- or post-cancer). Six recommendations for improving care were identified: addressing patient-provider communication, need to provide informational, emotional, and peer support, financial information, and decision-making support. AYA-Fs believed the best way to learn about resources was through online platforms or doctor-initiated discussions. Telehealth options and digital resources were generally considered acceptable. Face-to-face interactions were preferred for in-depth information, when AYA-Fs anticipated having immediate questions or distressing emotions, and with concerns about Internet security. Thus, a combined approach was preferred such that information (via web-based communication) should be provided first, with follow-up in-person visits and referrals when needed.

CONCLUSION

Informational and support services are needed to better educate patients about gonadotoxic effects and options to have children after cancer treatment is completed. Future work should evaluate how to best support oncology providers in meeting the needs of survivors concerned about fertility and family-building including referral to clinical specialties and supportive resources.
