title: Effect of oral contraceptive on ovarian function in young females undergoing neoadjuvant chemotherapy treatment for osteosarcoma.
abstract: We compared the residual ovarian function and the fertility of two groups of female patients treated at different times at the authors' institution by neoadjuvant chemotherapy for localized osteosarcoma of the extremities. From 1997 to 2000, one group of 31 females received neoadjuvant treatment according to the IOR 6 protocol, which included high-dose ifosfamide, high-dose methotrexate, adryamycin, and cis-platinum. In this group of patients an oral contraceptive (OC) was given in an attempt to prevent post-chemotherapy ovarian failure. Another group of 90 patients was treated between 1974 to 1995 with the same antiblastic drugs according to similar protocols (IOR 1-IOR 5). These patients did not receive OC or other treatment to protect ovarian function. There were no significant differences between the two groups of patients. Early chemotherapy-induced menopause occurred in 3 out of 19 postpubertal patients who received the OC and in 3 out of 71 postpubertal patients in the control group. In the OC group there were 2 cases of thrombophlebitis. No delay in menarche was seen in prepubertal patients. From statistical evaluation we underline that age and alkylant doses are the most important predictive factors for early menopause and that oral contraceptives during chemotherapy do not protect ovarian function in patients receiving high-dose alkylant based chemotherapy.
