Abstract
Objective:The aim of this study is to evaluate the long-term outcome of granulosa cell tumour (GCT) of the ovary in a large series of patients treated in MITO centres (Multicentre Italian Trials in Ovarian Cancer) and to define prognostic parameters for relapse and survival.Methods:A retrospective multi-institutional review of patients with GCTs of the ovary treated or referred to MITO centres was conducted. Surgical outcome, intraoperative and pathological findings and follow-up data were analysed. Kaplan-Meier and Cox proportional hazards analyses were used to determine the predictors for survival and recurrence.Results:A total of 97 patients with primary GCT of the ovary were identified. The median follow-up period was 88 months (range 6-498). Of these, 33 patients had at least one episode of disease recurrence, with a median time to recurrence of 53 months (range 9-332). Also, 47% of recurrences occurred after 5 years from initial diagnosis. At multivariate analysis, age and stage were independent poor prognostic indicators for survival; surgical treatment outside MITO centres and incomplete surgical staging retained significant predictive value for recurrence in both univariate and multivariate analyses.Conclusions:This study confirms the generally favourable prognosis of GCTs of the ovary, with 5-year overall survival approaching 97%. Nevertheless, prognosis after 20 years was significantly poorer, with 20-year survival rate of 66.8% and a global mortality of 30-35. These findings support the need for lifelong follow-up even in early-stage GCT. [ABSTRACT FROM AUTHOR]
