Abstract

Aim: This prospective randomized study compared the survival of patients with stage IB-IIIA gastric cancer treated with surgery alone or surgery followed by adjuvant chemotherapy. Patients and Methods: Patients with pathological stage IB-IIIA disease were randomly assigned to the following groups: surgery alone (n=116), or surgery followed by adjuvant chemotherapy with 5-fluorouracil, doxifluridine, or uracil-tegafur for 12 months (n=113). Results: The overall survival rate was 86.1% in the adjuvant group and 78.5% in the surgery-alone group. The overall survival rate did not significantly differ between the adjuvant-chemotherapy and surgery-only groups (p=0.163). In the subgroup analyses, patients with stage II disease and those receiving uracil-tegafur treatment in the adjuvant group showed significantly better prognosis than those in the surgery-alone group (p=0.036 and 0.005, respectively). Conclusion: This study did not find a significant survival benefit to be associated with adjuvant chemotherapy with fluoropyrimidines in patients with stage IBIIIA gastric cancer. However, it may be effective for patients with stage II disease. Additionally, uracil-tegafur is a promising agent for adjuvant chemotherapy of gastric cancer if S-1 is not available because of its toxicity.
