Abstract

OBJECTIVE
The purpose of this study is to evaluate the clinical and pathological characteristics of granulosa cell tumor of the ovary. METHODS: Between 1990 and 2000, 27 patients with granulosa cell tumor of the ovary treated in the Department of Obstetrics and Gynecology, College of Medicine, The Catholic University of Korea were identified and reviewed retrospectively for patient profiles, International Federation of Gynecologists and Obstetricians (FIGO) disease stage, mode of therapy, and length of survival. RESULTS: The median age at diagnosis was 43.9 years (range 9-75 years). Tumors were 70.3% (19/27) stage I, 7.5% (2/27) stage II, 11.1% (3/27) stage III, and 11.1% (3/27) stage IV. There was a 15% association between granulosa cell tumor and endometrial hyperplasia. All patients underwent cytoreductive surgery, and 14 patients followed by postoperative chemotherapy. One patient received adjuvant pelvic radiotherapy and 3 patients were treated with adjuvant pelvic radiotherapy and chemotherapy. The survival rate in stage I was 100.0% after 5 years, and in stage II-IV was 62.5% after 5 years. Overall survival was 88.8% at 5 years. Mitotic index influenced the survival rate; with less 10/10 HPF the survival was 100% in 5 years, and with more or equal 10/10 HPF the longest survival was 44 months. CONCLUSION: Although most granulosa cell tumors of the ovary are slow growing, wide variation is possible, with high mitosis counts leading to a worse prognosis. However, it is difficult to predict early or late recurrences using pathologic parameters. It is therefore important that patients with theses tumors are followed up indefinitely.
