During the 10-year period from January 1975 through December 1985, 48 patients with low malignant potential epithelial ovarian tumors were treated on the Gynecology Service at Memorial Sloan-Kettering Cancer Center. No patients were lost to follow-up and the mean duration of follow-up was 42 months. Twenty-nine patients were Stage I, 5 patients were Stage II, 11 patients were Stage III, 1 patient was Stage IV, and 2 patients were unstaged. Patients were divided into those with no residual disease after initial surgical treatment (29), microscopic residual disease (7), and gross residual disease (12). No patient without residual disease died from cancer. Of the 19 patients with residual disease, all received adjunctive chemotherapy alone, radiation therapy alone, or a combination of both. Three of 19 patients died from cancer. Twelve patients with residual disease were found to be free of disease at second-look surgical reassessment following adjunctive therapy. This review indicates that adjunctive therapy can eradicate residual disease in patients with epithelial ovarian tumors of low malignant potential.
