    Abstract:
    In an attempt to substitute ftorafur for burdensome 5-fluorouracil (5-FU) infusions, 52 previously untreated patients were randomized to receive ftorafur with either mitomycin C or methyl-CCNU. Ftorafur was administered monthly as a 2-hour infusion daily x 5 days. Mitomycin C and methyl-CCNU were repeated every 8 weeks. A response rate of 27% (seven responses among 26 patients) was demonstrated on the mitomycin C arm compared to a response rate of 15% (four responses among 26 patients) on the methyl-CCNU arm (P = 0.25). There was no significant difference in the median survival between treatment arms. Central nervous system toxicity occurred in greater than 30% of the patients and appeared to be the limiting factor with ftorafur administration. Alternate schedules of ftorafur should be explored since there appears to be little advantage of a daily ftorafur schedule over conventional 5-FU infusions.
