Reproductive Care of Childhood and Adolescent Cancer Survivors: A 12-Year Evaluation.

Background: Reproductive complications for cancer survivors are identified as one of the top unmet needs in the survivorship period. However, current models of cancer care do not routinely incorporate reproductive follow-up for pediatric or adolescent cancer patients. The Kids Cancer Centre has had a one-stop survivorship clinic that includes the attendance of a gynecologist and fertility specialist for the last 12 years. Methodology: To inform the future development of our reproductive survivorship care, we reviewed the reproductive care our survivorship clinic has provided over a 12-year period, specifically reviewing the electronic and patient records to collect information on the demographics of the patients who used the service and their gonadotoxic risk and associated fertility treatment, their documented reproductive needs and concerns, and information provided on preventative reproductive advice and screening. Main Results: Two hundred seventy-eight patients were seen (397 consultations) for advice and management of reproductive issues, including 189 female patients (68.0%). Survivors' median age at follow-up was 25.0 years (range = 6-50), on average 19.2 years from their primary diagnosis (range = 3-46). The reviewed data had five overarching themes (fertility care, hormone dysfunction, sexual dysfunction, fertility-related psychological distress due to reproductive concerns, and preventative health care), although each theme had a number of components. Patients had on average 2.5 reproductive concerns documented per consultation (range 1-5). The three most commonly documented symptoms or concerns at the initial consultation related to fertility status (43.9%), endocrine dysfunction (35.3%), and contraception advice (32.4%). In patients younger than 25 years, documented discussions were predominately about endocrine dysfunction, fertility status, and contraception, while dominant themes for 26-35-year olds were fertility status, reproductive-related health prevention strategies, contraception, and endocrine dysfunction. Survivors 36-45 years of age prioritized fertility status, pregnancy, and contraception. Fertility preservation (FP) (p = 0.05), preventative health strategies (p = 0.001), and contraception advice (p < 0.001) were more commonly discussed by females than males. Conclusion: Young cancer survivors have multiple ongoing reproductive concerns that change over time. Assessing survivors' reproductive potential following cancer treatment is important as it gives patients who have not completed their family planning an opportunity to explore a possible window to FP or Assisted Reproductive Treatment. Our data can assist in informing the model of care for a reproductive survivorship clinic.

Fertility Preservation for Child and Adolescent Cancer Patients in Asian Countries.

Background: At present, fertility is one of the main concerns of young cancer patients. Following this trend, "fertility preservation (FP)" has been established and has become a new field of reproductive medicine. However, FP for child and adolescent (C-A) cancer patients is still developing, even in advanced countries. The aim of the present study was to assess the barriers to FP for C-A patients by investigating the current status of FP for C-A patients in Asian countries, which just have started FP activities. Method: A questionnaire survey of founding members of the Asian Society for Fertility Preservation (ASFP) was conducted in November 2018. Main findings: Of the 14 countries, 11 country representatives replied to this survey. FP for C-A patients is still developing in Asian countries, even in Australia, Japan, and Korea, which have organizations or academic societies specialized for FP. In all countries that replied to the present survey, the patients can receive embryo cryopreservation (EC), oocyte cryopreservation (OC), and sperm cryopreservation (SC) as FP. Compared with ovarian tissue cryopreservation (OTC), testicular tissue cryopreservation (TTC) is an uncommon FP treatment because of its still extremely experimental status (7 of 11 countries provide it). Most Asian countries can provide FP for C-A patients in terms of medical technology, but most have factors inhibiting to promote FP for C-A patients, due to lack of sufficient experience and an established system promoting FP for C-A patients. "Don't know how to provide FP treatment for C-A" is a major barrier. Also, low recognition in society and among medical staff is still a particularly major issue. There is also a problem with cooperative frameworks with pediatric departments. To achieve high-quality FP for C-A patients, a multidisciplinary approach is vital, but, according to the present study, few paramedical staff can participate in FP for C-A patients in Asia. Only Australia and Korea provide FP information by video and specific resources. Conclusion: The present study demonstrated the developing status of FP for C-A patients in Asian countries. More intensive consideration and discussion are needed to provide FP in Asian societies based on the local cultural and religious needs of patients.
