Identifying Issues in Fertility Preservation for Childhood and Adolescent Patients with Cancer at Pediatric Oncology Hospitals in Japan

We conducted a questionnaire survey in 15 pediatric oncology hospitals in Japan to better understand the current status of fertility preservation in childhood and adolescents. The survey period was from September 2020 to December 2020. We mailed questionnaires to 64 departments involved in pediatric cancer treatments at the 15 hospitals. The primary outcomes were the timing of providing explanations on fertility preservation, presence of health care provider while providing explanations, cooperation between medical staff, and cooperation between hospitals. The response rate was 100% (64/64). Regarding the time at which this information was provided, 79.6% of patients (43/54) received it before cancer treatment; 5.6% (3/54), after remission; and 14.8% (8/54), both time points. Nurses were mostly in attendance (70%) when oncologists provided information to patients. Nine (60%) hospitals did not have a reproductive department. Among these, 28.6% of the respondents referred patients to a reproductive facility that performed fertility preservation. Providing information about fertility preservation was challenging owing to the shortage of specific explanatory materials (35.1%) and the lack of cooperation between pediatric oncologists and reproductive endocrinologists (24.6%). Based on this survey, educational activities regarding fertility preservation centered on pediatric oncologists and nurses are needed. Furthermore, a system for providing explanatory materials for fertility preservation and encouraging cooperation at the physician and hospital levels is also needed (IRB No. H2020-111).
