Precancerous lesions of the stomach

Abstract

Abstract The etiology of stomach cancer in relation to preexisting mucosal alterations is described and discussed from a review of the literature and our own previously reported experience. The incidence of “cancerization” or malignant change of gastric polyp, chronic gastric ulcer, and chronic gastritis varies considerably from researcher to researcher. Clinical follow‐up studies in many cases of gastric polyp and chronic ulcer discovered in the mass survey examination of the stomach revealed incidences of malignant degeneration of 2.3% of the gastric polyp cases and 2.06% of the gastric ulcer cases.
