Chemotherapy-induced amenorrhea and its effects on fertility in long-term female survivors of classic osteosarcoma.

Abstract

To explore the effect of chemotherapy-induced amenorrhea (CIA) on female osteosarcoma patients' fertility function, we investigated and analyzed their marital status, fertility, and menstrual status in a retrospective cohort study. We selected female osteosarcoma patients from database from January 2004 to December 2013. Patients' characteristics such as age, tumor location, marital status, menstrual status, and fertility status were collected. The data were analyzed using the Statistical Package for the Social Sciences (SPSS), version 22. A total of 122 female patients met these criteria and finally responded by questionnaire and telephone follow-up. The marriage rate of female osteosarcoma survivors was 50.8% (62/122), which was significantly lower than the control group (p = 0.000). The average marriage age of female osteosarcoma survivors was 25.5, which was obviously higher than the control group (p = 0.000). CIA occurred in 46 (36.1%) patients. We then found that the incidence of CIA was higher in older patients. (p = 0.011). All of the married patients wanted to have children, and 67.8% (42/62) of them had given birth after chemotherapy. The fertility of married patients with CIA was significantly reduced compared to that of married patients without CIA. (p = 0.001). The patients with CIA have higher risk of impaired reproductive function than those who did not. Fertility preservation option before the start of the chemotherapy is important. And it is much value to record menstrual pattern and detect sex steroid levels after 6months of therapy in order to be able to evaluate the fertility status.
