PURPOSE: Improved treatment for childhood cancer has led to better survival rates of 83 % today.
However, long-term side effects including infertility of pediatric patients receiving oncologic treatment remain unclear. We examined the association of chemotherapy and radiotherapy with infertility in survivors of pediatric cancer.
METHODS: A questionnaire on fertility was sent to adult survivors listed in the German Childhood Cancer Registry. Fertility status was defined based on information on attempts to conceive, pregnancies, births, menstrual cycle and previous fertility test results.
RESULTS: Therapeutic data were obtained from treatment optimization trials. We included 618 childhood cancer survivors (384 women) who reported information allowing us to classify their current fertility status as 'fertile/probably fertile' or 'probably infertile'. Thirty-one percent of 83 female and 29 % of 117 male survivors reported infertility based on previous fertility tests. 'Probably infertile' adult survivors were more likely to have received pelvic radiotherapy (women: adjusted OR 20.24, 95 % CI 4.69-87.29; men: 12.22; 1.18-126.70) than those who were 'fertile/probably fertile'. Etoposide, particularly ≥5,000 mg/m2 in women, and carboplatin and/or cisplatin in both sexes seemed to have independent risk potential for infertility. Similarly, cancer treatment during or post-puberty compared to treatment before puberty showed a trend toward increased infertility, particularly in male survivors.
CONCLUSIONS: Patients and families need to be informed about fertility-preserving measures prior to and also after chemotherapy and radiotherapy.
