A STUDY OF PRECANCEROUS GASTRIC LESIONS IN A HIGH RISK POPULATION

A study of precancerous gastric lesion was conducted in a randomly selected high risk population in Linqu, Shandong Province of China. 849 subjects aged from 30-64 were examined bioptically. There were 8 cases of gastric cancer, the prevalence rate was 0.9%. 169 subjects were diagnosed to be dysplasia, the prevalence rate of dysplasia was increased significantly with age. The regression equation was Y=0.47X-0.25. The prevalence of CAG was found in 36 per cent of the studied subjects and both dysplasia and CAG were more serious in the antrum than the. fundus. The results showed a natural history of precancerous gastric lesions in a high risk population in a high risk area.
