Postoperative long term chemotherapy for advanced gastric cancer.

A postoperative long term chemotherapy was carried out against stage IV gastric cancer with Mitomycin-C, Futraful and a plant polysaccharide, PS-K. The 2-year survival rate was 15 per cent in patients who received an intraoperative Mitomycin-C alone, while it increased to 34 per cent in those receiving the anticancer agents for a prolonged period. The postoperative long term chemotherapy is assumed to be an effective means of improving the therapeutical results of gastric cancer.
