Randomized trial of adjuvant chemotherapy with mitomycin plus ftorafur versus mitomycin alone in resected locally advanced gastric cancer.

PURPOSE: We performed a clinical trial to determine whether postoperative adjuvant chemotherapy with two drugs versus one drug could prolong survival. PATIENTS AND METHODS: From 1985 to 1996, 85 patients with completely resected locally advanced gastric cancer were enrolled. The subjects were randomized into two treatment groups, as follows: mitomycin (MMC) 10 to 20 mg/m2 intravenously (i.v.) on day 1 every 6 weeks plus ftorafur (FT) 500 mg/m2/d for 36 consecutive days; or MMC alone, 10 to 20 mg/m2 i.v. every 6 weeks. All courses were repeated four times.
RESULTS: After a median follow-up duration of 62 months, the overall 5-year survival rates were 67% for the MMC-FT group versus 44% for the MMC group (P = .04). Subgroup analysis to compare survival curves using the method of Mantel-Cox showed survival rates significantly in favor of the MMC-FT group in the subsets of patients with node-negative disease (P = .01) and those whose disease was stage IB or II (P = .008).
CONCLUSION: Significantly better survival results were observed for MMC-FT versus MMC alone. Subset analysis suggest a strong benefit in patients with node-negative and early-stage resected gastric cancer.
