Decreased fertility among female childhood cancer survivors who received 22-27 Gy hypothalamic/pituitary irradiation: a report from the Childhood Cancer Survivor Study.

摘要

OBJECTIVE: To evaluate the effect of hypothalamic/pituitary radiation (HPT RT) dose on the occurrence of first pregnancy. DESIGN: Retrospective cohort study of childhood cancer 5-year survivors (CCS) diagnosed between 1970 and 1986 before 21 years of age at one of 26 North American pediatric cancer treatment centers. SETTING: Self-administered questionnaire. PATIENT(S): A total of 3,619 female CCS who participated in the Childhood Cancer Survivor Study and received no or scatter (/=22 Gy compared with those CCS receiving no HPT RT. CONCLUSION(S): These results support the hypothesis that exposures of 22-27 Gy HPT RT may be a contributing factor to infertility among female CCS.
