Phase II trial of 10-deazaaminopterin for advanced hypernephroma
Carcinoma, Renal Cell
Folic Acid Antagonists
10-Deazaaminopterin, a derivative of aminopterin with enhanced cellular uptake relative to methotrexate, was given to fourteen patients with advanced measurable hypernephroma. The dose-limiting toxicity was mucositis. Abnormalities in liver function were seen in 8 patients. No responses were seen in 13 adequately treated patients including 10 who had received no prior chemotherapy. The unique transport of this new group of compounds is discussed.
