We examined the effects of postoperative 5-fluorouracil (5-FU) infusions and oral treatment with 1-hexylcarbamoyl-5-flourouracil (HCFU) on patients curatively resected for stages II-IV colorectal cancer. The study was prospectively randomized, and 251 (93.3%) of 269 patients were valid candidates for statistical assessment. The inductive regimen for group A included 5-FU 10 mg intravenous (iv) injections on days 0, 1, 2, 7, 8 and 9, postoperatively. For maintenance therapy, group A received HCFU 300 mg orally and daily for 52 weeks beginning 2 weeks after surgery. The regimen for group B included only 5-FU injections. The effects of this chemotherapy were also retrospectively analyzed for groups at a high risk for recurrence stages, III-IV, transmural invasion-positive and lymph node metastasis-positive cases. There was no statistical difference in survival time between the groups for 251 eligible cases (p = 0.079). In group A given 5-FU plus HCFU, there was a reduction in the recurrence rate for patients with stages III-IV, or lymph node metastasis-positive colorectal cancers (p < 0.05) and prolongation of the survival time for patients with stage III-IV, transmural invasion-positive or lymph node-positive colorectal cancers (p < 0.05). Our findings show that the combination of 5-FU infusion and the continuous administration of HCFU is effective in treating patients with surgically resected colorectal cancer who are at high risk for a recurrence.
