Abstract
Vindesine, a newer vinca alkaloid, has been demonstrated to have activity against colorectal cancer during phase I studies. This report describes the results of the two phase II trials in which vindesine was administered with 5-fluorouracil (5-FU) or in combination with 5-FU and methyl-1,3 cis(2 chloroethyl)-1-nitrosourea (MeCCNU). One of 16 patients (6%) given 5-FU-vindesine, and 4 of 31 (13%) patients in the 5-FU-vindesine-MeCCNU group achieved partial response (PR). Stable disease was observed in 50% of the 5-FU-vindesine and 48% of the 5-FU-vindesine-MeCCNU group. In each treatment group, survival of respondents and those with stable disease was statistically superior (p < 0.02) to that of those with progressive disease; there was no difference however, in overall survival between the two treatment groups and no enhancement of survival compared to published reports of results with 5-FU alone. No chemotherapy-related deaths occurred and both treatment regiments were well tolerated. Myelosuppression, which occurred with equal (50%) frequency in both regimens, was the major dose-limiting toxicity. MeCCNU increased the incidence of gastrointestinal toxicity. Vindesine neurotoxicity occurred in approximately 4% of the evaluable courses in each group. Combination therapy with 5-FU-vindesine with or without MeCCNU in the dosages administered did not significantly increase the activity of 5-FU. Further evaluation of vindesine will require dosage modification.
