Objective. To evaluate the oncologic and reproductive outcomes and to analyze prognostic factors after fertility-sparing surgery in patients with early and advanced malignant ovarian germ cell tumors (MOGCTs). Methods. This study included 171 patients who underwent fertility-sparing surgery. Data were gathered from patients' medical records. Survival analysis was performed using the log-rank test and Cox's proportional hazards model. Reproductive outcomes were analyzed. Results. Twenty-five patients (14.6%) had recurrent disease, and five patients (2.9%) died of disease during the median follow-up time of 86 months (range, 9-294 months). The 5-year disease-free survival (DFS) was 86%, and the 5-year overall survival (OS) was 97%. The 5-year DFS was 84% for stage I and 89% for stage II-IV. The 5-year OS was 99% for stage I and 91% for stage H-IV. In multivariate analysis, yolk sac tumor, incomplete staging surgery, and residual tumor were independent risk factors for reduced DFS, and yolk sac tumor and residual tumor were independent risk factors for reduced OS. Reproductive and obstetric outcomes were evaluable in 124 patients, and 106 patients (85.5%) had regular menstruation, 12 patients (9.7%) had irregular menstruation, and six patients (4.8%) had premature menopause. Twenty patients tried to conceive, 15 patients (75%) succeeded in achieving 21 pregnancies, and 13 of the patients (65%) gave birth to 20 healthy babies. Conclusion. Fertility-sparing surgery has excellent survival outcomes in young women with MOGCTs, even in advanced stages. Reproductive and obstetric outcomes were promising. Yolk sac tumor, incomplete surgical staging, and residual tumor were independent prognostic factors. (C) 2017 Elsevier Inc. All rights reserved.
