The authors analyzed the epidemiologic and histological characteristics and the management of ovarian carcinoma of low malignant potential (LMP) at a university hospital between 1990 and 2000. The authors carried out a retrospective study reviewing hospital charts. Based on the records experience with 29 such tumors is peresented. Of these 20 (74%) were of the serous variety, 7 (26%) were mucinous. LMP tumors accounted for 16% of proliferating epithelial ovarian tumors. They occured at a mean age of 45 years. The LMP tumors were bilateral in 12% of the cases. The majority of patients (87%) with LMP tumors presented with early stage disease. Tumor markers such as CA-125 were not always elevated as in invasive ovarian carcinoma. Laboratory investigations have not demonstrated that these tumors represent an intermediate step between benign ovarian tumors and carcinoma. The recommended therapy is surgical, consisting of total abdominal hysterectomy, bilateral salpingo-oophorectomy, peritoneal washings, and tumor debulking. Conservative surgery consisting of unilateral salpingo-oophorectomy is considered to be an appropriate treatment for young women with early stage LMP ovarian tumors who wish to retain their fertility potential. 50 percent of women who underwent conservative surgery subsequently conceived in this study. There were no recurrences in the study group, so the authors conclude that the long term outcome of LMP tumors is extremely favorable.
