[Clinical effect of postoperative adjuvant chemotherapy for advanced colorectal cancer--comparisons of between tegafur (FT) and UFT].
A randomized controlled study was conducted on a FT 600 mg/day daily oral administration group and a UFT 400 mg/day daily oral administration group as an adjuvant chemotherapy after curative operation for colorectal cancer patients with injection of Mitomycin 30 mg (20 mg during operation and 10 mg on the day following), and the results were examined. FT and UFT were administered orally for one year from the 3rd week after operation. The 5-year survival rate was slightly higher in the UFT administration group. Five-year survival was 82.7% for colon cancer and 82.1% for rectal cancer in the UFT administration group, against 72.6% and 72.0 % in the FT administration group. The same trend was observed when the survival rate was studied by various factors such as the size of tumor, depth of cancer invasion of the wall, histological type, lymph node metastasis, vascular invasion and the degree of progression. There was no difference between both groups in the patterns and times of recognition of the recurrences and in the appearance rate of side effects. The results suggest that UFT 400 mg/day is equal to or better than FT 600 mg/day in therapeutic effect for colorectal cancer patients, although the UFT dose is only 2/3rd the FT dose.
