N2 - Aims: This study aimed to investigate the outcome of patients with malignant ovarian germ cell tumors (MOGCTs) and to define the risk factors for recurrence. Methods: A total of 123 patients with MOGCTs were retrospectively reviewed among MITO centers. Eighty-one patients had primary treatment in a MITO center, whereas the other 42 were referred for adjuvant chemotherapy or recurrence. The clinicopathologic characteristics were evaluated for association with relapse or death. Results: Median age was 24 years (range, 11-76 years). Forty-nine (39.8%) had dysgerminomas, 35 (28.5%) had immature teratomas, 12 (9.8%) had mixed germ cell tumors, 26 (21.1%) had yolk sac tumors, and 1 (0.8%) had embryonal carcinoma. International Federation of Gynecology and Obstetrics stage distribution was as follows: stage I, 87 (70.7%); stage II, 3 (2.4%); stage III, 29 (23.6%); and stage IV, 4 (3.3%). Fertility-sparing surgery was performed in 92 patients, whereas the remaining 31 received radical surgery; 65.8% of patients received adjuvant chemotherapy. Recurrence rate was 17.8% and the median time to recurrence was 9 months. Univariate and multivariate analyses showed that patient age (>45 years) and treatment outside a referral (MITO) center were the most important predictors of recurrence. The 5-year overall survival rate was 88.8%, with a median follow-up of 61 months. Univariate and multivariate analyses demonstrated that stage greater than I and yolk sac tumors were independent poor prognostic indicators. Conclusions: This study confirms that MOGCTs have excellent prognosis, with 5-year overall survival rates of 95.6% and 73.2% in stage I and advanced stages, respectively. Age older than 45 years and treatment not in a referral center are independent risk factors for recurrence, whereas stage greater than I and yolk sac histology are independent poor prognostic indicators.
