Abstract
OBJECTIVE: Adult granulosa cell tumors (AGCTs) account for less than 5 % of all ovarian malignancies, whereas the majority (95 %) occurs after the age of 30 (adult-type) and present at an early stage. Aim of this study is to identify clinical and pathological risk factors for recurrence in early stage AGCTs. METHODS: Retrospective review of patients with AGCT of the ovary, treated surgically at our institution from 1996 to 2011. Clinical, pathological and follow-up data were collected. Systematic analysis was performed to determine variables for predicting recurrence. RESULTS: In total, 43 patients were identified. The mean age at diagnosis was 54.3 years and 65.1 % of them were postmenopausal. All patients underwent surgical staging and intraoperative rupture of the tumor occurred in four of them (9.3 %). The majority of the cases were staged as IA (72.1 %) while 10 (23.3 %) were staged as IC and only two patients as IIB. Mitotic index was 4 or more in 34.9 % of the patients and nuclear atypia was moderate to high in 60.5 %. During follow-up period (mean 9.2 years), recurrence occurred in three patients (7 %) with no deaths recorded so far. The cumulative recurrence free rate for the first 2 years was 97.6 % (SE = 2.4 %), for 5 years 94.9 % (SE = 3.5 %) and for 10 years 91.0 % (SE = 5.1 %).Tumor size, stage and mitotic index proved to be independent predictors for recurrence at the multivariate analysis. CONCLUSIONS: Recurrence in early stage AGCT seems to be associated with stage, tumor size and mitotic index. All the above should be taken into consideration when tailored postoperative management is planned.
