Brief Communication: Therapy of Advanced Colorectal Cancer With a Combination of 5-Flourouracil, Methyl-l,3-cis(2-chlorethyl)-1-nitrosourea, and Vincristine

: In a randomized, controlled study of 80 patients with advanced colorectal carcinoma, the combination of 5-fluorouracil (5-FU), methyl-1, 3-cis(2-chlorethyl)-1-nitrosourea, and vincristine produced an overall degree to toxicity comparable to that of 5-FU used alone. At 10 weeks, a positive objective response rate of 43.5% was observed with the three-drug combination compared to 19.5% with 5-FU alone (P less than 0.5).
