Obstetric Results after Fertility-Sparing Management of Non-Epithelial Ovarian Cancer

Purpose: To assess the recurrence and birth rates among patients with non-epithelial ovarian cancer. Methods: The study included 146 patients with germ cell (GCT, n = 84) and sex cord-stromal tumors (SCST, n = 62), who underwent fertility-sparing surgery. Adjuvant chemotherapy was administered to 86 (58.9%) patients. Most cases (133 out of 146) were staged FIGO I. Results: The 5-and 10-year disease-free survival rates were 91% and 83%, respectively. The recurrence risk was not associated with tumor histology, stage or age. Twenty-four months after the treatment, the rate of recurrence was higher than the rate of childbearing. The childbearing rates kept rising after the treatment and exceeded the rate of recurrence after 2 years. The cumulative incidence rates of birth 36, 60 and 120 months after treatment were 13.24%, 20.75%, and 42.37%, respectively. Chemotherapy was not related to childbearing. The patients' age was related to the chance of childbearing. Conclusions: The prognoses of GCT and SCST are similar. Close follow-ups along with contraception should be offered to women during the first two years after treatment due to the increased risk of recurrence. After this period, relapses are rare and women can safely become pregnant.

Automated summary

This study aimed to evaluate the recurrence and birth rates among patients with non-epithelial ovarian cancer. A total of 146 patients who underwent fertility-sparing surgery for germ cell (GCT) and sex cord-stromal tumors (SCST) were included. The 5- and 10-year disease-free survival rates were 91% and 83%, respectively. After a 24-month follow-up, the recurrence rate was higher than the rate of childbearing, but after 2 years, the childbearing rates exceeded the rate of recurrence.
