Abstract

Sex-cord stromal tumors of ovary account for 5~8% of all ovarian malignancies. This group of ovarian neoplasms is derived from the sex cords and the ovarian stroma or mesenchyme. Although they can occur in women of all ages, they tend to have peak incidence in those over age50. So they should be surgically managd with hysterectomy and bilateral salpingo-oophorectomy. The purpose of this study is to report the experience at Asan Medical Center, Department of Obstetrics and Gynecology, in 24 patients with ovarian sex-cord stromal tumortreated between May, 1989 and April, 1995. We analyzed the effect of histologic subtype, FIGO stage, age and management. The results were as follows: 1. In histologic subtypes, fibrothecoma(66.7%), granulosa cell tumor(20.8%), Sertoli-Leydig cell tumor(8.3%), others(4.0%) were counted in order. 2. The mean age of sex cord-stromal tumor was 44.0 years and 8 cases(33.4%) of tumors over the age of 50.0 years, 13 cases(54.2%) over the age of 40.0 years. 3. Main initial symptoms were abdominal pain(37.5%), asymptomatic cases(25.0%), abdominal mass palpation(16.6%), irregular menstruation(12.5%) in order. 4. Management was surgery only(91.7%), surgery and chemotherapy(8.3%). 5. The mean disease free survival was 30.6 months.
