Abstract | BACKGROUND: Although surgical resectability is an important prognostic factor, recurrences are commonly noted in advanced colorectal cancer patients, even after apparently curative surgery. Since such recurrences cannot be cured, better adjuvant chemotherapies are urgently required. PATIENTS AND METHODS: We studied the effect of post-operative chemotherapy using oral administration of 1-hexylcarbamoyl-5-fluorouracil ( HCFU) with 5-fluorouracil (5-FU) infusion for curatively-resected Stage IIIa and IIIb colorectal cancers. This study was prospectively randomized and controlled and 314 (97.8%) out of 321 patients were determined to be candidates for statistical assessment. Group A and Group B received 5-FU intravenous injection at, respectively, 333 mg/m2 and 1000 mg/m2 body surface area/24 hours continuously for 72 hours beginning on post-operative day 0 and day 6, with oral HCFU 300 mg daily for 52 weeks beginning 2 weeks after surgery. RESULTS: There were no differences in overall 5-year survival or disease-free survival between Group A and Group B. A retrospective subset analysis. however, suggested that the protocol of Group B tended to yield better 5-year survival (68.3%) for rectal cancer than that of Group A (58.8%). CONCLUSION:
