[Cimetidine treatment of stomach cancer]

The effect of cimetidine treatment in cancer of the stomach was investigated in a double-blind, multicentre study comprising eight departments in Greater Copenhagen. Immediately after operation (or the decision not to operate) 181 patients were subdivided at random to treatment with a placebo or cimetidine in a dosage of 400 mg twice daily for two years or until death. Compliance control was carried out every third month. The mean survival in the cimetidine group (450 days, 1-1,826) was significantly longer (p = 0.02) than in the placebo group (316 days, 1-1,653).
