AIM To test the hypothesis that Helicobacter pylori eradication alone can reduce the incidence of gastric cancer in a subgroup of individuals with an increased risk for this fatal *** It is a prospective, randomized,double-blind, placebo-controlled multinational multicenter trial. Men between 55 and 65 years of age with a gastric cancer phenotype of Helicobacterpylori gastritis are randomized to receive a 7-day course of omeprazole 2 × 20 mg,clarithromycin 2 × 500 mg, and amoxicillin 2 ×lg for 7 days, or omeprazole2 × 20mg plusplacebo. Follow - up endoscopy is scheduled 3months after therapy, and thereafter in one-year intervals. Predefined study endpoints are gastric cancer, precancerous lesions (dysplasia, adenoma), other cancers, *** Since March 1998, 1524 target patients have been screened, 279 patients (18.3%) had a corpus-dominant type of *** gastritis, and 167 of those were randomized (58.8%). In the active treatment group (n -- 86), H. pylori infection infection was cured in 88.9% of patients. Currently, thecumulative follow-up time is 3046 months (253.8patient-years, median follow-up 16 months). So far, none of the patients developed gastric cancer or any precancerous lesion. Three(1.8%) patients reached study endpoints other than gastric *** Among men between 55 and 65years of age, the gastric cancer phenotype of *** gastritis appears to be more common than expected. Further follow- up and continuing recruitment are necessary to fulfil the main aim of the study.
