Phase I-II study of ftorafur and methyl-ccnu in advanced colorectal cancer

Abstract
The combination of Ftorafur (NSC-148958) and methyl-CCNU (NSC-95441) was evaluated in 36 patients with advanced colorectal cancer. The principle toxicities encountered were myelosuppression, gastrointestinal, and neurological. There were no complete responses and only 5/34 (14.7%) patients achieved a partial response. Methyl-CCNU and Ftorafur does not appear to be an effective combination in advanced adenocarcinoma of the colon and rectum.
