title: Phase II study of N-methylformamide (N-MF) (NSC 3051) in patients with advanced epithelial ovarian cancer. A Gynecologic Oncology Group study.
abstract: Forty-four patients with advanced, measurable, epithelial carcinoma of the ovary were treated with 97 courses of N-methylformamide (N-MF) at doses ranging from 600-800 mg/m2, intravenously, daily for 5 days every 28 days. Forty-one patients had prior surgery and had received one prior chemotherapy regimen. Only seven patients had received any prior radiation therapy. All patients were Gynecologic Oncology Group (GOG) performance status 0, 1, or 2. Three partial responses were seen. Hematologic adverse effects were extremely rare as predicted by early clinical trials. One major toxicity was a syndrome consisting of some combination of myalgias, arthralgias, pleuritic pain, abdominal pain, peripheral neuropathy, anorexia, lethargy, and declining performance status (pain-lethargy syndrome) that was reversible with discontinuation of the drug. This adverse effect was as common a reason as hepatic toxicity for discontinuation of N-MF. As reported in previous studies with this drug, hepatic toxicity was also common, usually reversible, and also a cause for discontinuation of the drug. The low level of clinical activity and the unpleasant adverse effects in this population of patients with previously treated ovarian cancer makes it unlikely that this drug will play any significant role in treatment of epithelial ovarian cancer.
