Chemotherapy of advanced ovarian epithelial carcinoma with melphalan and levamisole: a pilot study of the Gynecologic Oncology Group.

Twenty-three patients with Stage III, Stage IV, or recurrent epithelial ovarian cancer were treated with a combination of melphalan and levamisole to determine a tolerable dosage schedule, possible adverse effects, and a general estimate of response rate and duration. In seven patients with measurable disease there were four complete responses (57%) with a median duration of 75 weeks. Two of the complete responders have had negative second-look laparotomies while the other two patients have had subsequent progression. Of 16 patients with nonmeasurable disease two have had negative second-look laparotomies and two remain progression free. Thus 8 of 23 patients (35%) had complete responses or remain progression free whereas 4 of 23 patients (17%) have had negative second-look laparotomies. No serious toxicity was encountered. Immunologic monitoring did not indicate significant immunologic reconstitution in these immunosuppressed patients.
