The study was made of 568 cases of "initial" cancer cases, 825 morphological substrates of the polyps and 90 ones of chronic gastric ulcer. Chronic gastritis was the most frequent precancer disease (88.7% of cases). Malignant polyps accounted for 10.7% and chronic ulcer for 0.6% of cases. Relevant criteria for risk groups are proposed. Severe epithelial dysplasia as a morphological manifestation of gastric precancer can serve a marker of the risk of malignant transformation.
