[Current status of adjuvant chemotherapy of gastric cancer].

Effect of adjuvant chemotherapy on the postoperative survival of gastric cancer patients has been suggested by various clinical trials with an aim of controlling minimum residual tumors after surgery. Incorporation of adjuvant chemotherapy with MMC, 5-FU, FT-207, or immunomodulators into the treatment modalities might be one of the basic treatment strategies for gastric cancer. Well designed, controlled trials in terms of selecting proper drugs and patients, and of statistical methodology, are essential for the proper evaluation of the adjuvant chemotherapy.
