[The treatment of borderline ovarian tumors and its prognosis]

Twenty patients with ovarian borderline epithelial tumors were analysed. The tumor in 9 patients were serous and in 11 patients mucinous in nature type. 15 cases were classified as of stage I, 3 cases of stage II and 2 cases of stage III, according to the FIGO staging. All pathologic slides were re-reviewed to confirm the diagnosis and no patients were lost to follow-up. Total hysterectomy and unilateral or bilateral salpingo-oophorectomy were done in 12 patients, among whom, 2 died of tumor recurrences. Unilateral adnexectomy was done in 8 patients, and none died of tumor recurrence. Fourteen patients received post operative chemotherapy 1-8 courses with PAC regimen, 12 patients were alive up to the present. Six patients did not receive chemotherapy and among these 3 with stage Ia were alive and 1 with stage Ib died of tumor recurrences. The survival rate of stage I was 92.3%. Our results indicated that the prognosis was closely related to clinical staging. We suggested that patients of stage I who wish to preserve childbearing function may be treated with unilateral salpingo-oophorectomy, and chemotherapy should be given to the patients with high risk factors. Because of the indolent nature of these tumors, long-term follow-up at least 10 years is necessary.
