Abstract

OBJECTIVE
The purpose of this study is to know the pathological and clinical characteristics of granulosa stromal cell tumor of the ovary.
METHODS
From January 1996 to December 2005, patients with granulosa cell tumor of ovary and ones with thecoma, which are included in granulosa stromal cell tumor of the ovary, treated in the Obstetrics and Gynecology, College of Medicine, the Kyungpook National University Hospital of Korea were identified and reviewed retrospectively for patient profiles, mode of therapy, length of survival and so on.
RESULTS
There were 14 granulosa cell tumors, and 55 thecomas. The mean age of patients with granulosa cell tumor was 46.8 years old, and 7 women (50.0%) were menopausal. Bilaterality was absent, and mean size of tumor was 11.1 cm. The chief complaints of patients were 3 cases (21.4%) of abdominal discomfort or pain, 3 cases (21.4%) of vaginal bleeding and 4 cases (28.6%) of no symptom. Of 14 cases, total abdominal hysterectomy with bilateral salpingo-oophorectomy was performed in 5 cases (35.7%). Chemotherapy was performed in 5 cases (35.7%), and regimen was combination of BEP (bleomycin+etoposide+cisplatin). According to FIGO staging, 10 cases (71.4%) were stage I. Second look operation was done in one case (7.1%). Among 14 patients of follow-up, one patient (7.1%) was expired. Surgical staging was associated with survival rate of patients. The mean age of patients with thecoma was 49.6 years old, and 28 women (50.9%) were menopausal. Bilaterality was 3 cases (5.4%), and mean size of tumor was 8.5cm. The chief complaints of patients were 14 cases (25.4%) of abdominal discomfort or pain, and 19 cases (34.5%) of no symptom. Of 55 cases, total abdominal hysterectomy with bilateral salpingo-oophorectomy was performed in 21 cases (38.2%). Among 55 patients of follow-up, all patients survived.
CONCLUSION
Thecomas are regarded as benign tumors but granulosa cell tumors are characterized by a long natural history with a significant capacity to recur years after apparent clinical cure. The patients with granulosa cell tumor should be followed up indefinitely.
