Abstract
During recent 13 years from 1967 through 1980, a total number of 458 cases of gastric carcinoma were resected at Karasawa Icho-Byoin Hospital, Asahikawa, Hokkaido. The patients were divided into age groups according to their age by decade and clinicopathological studies were made to search for whether or not there are any characteristic features present in the age groups. Incidence of juvenile gastric carcinoma in the teens and twenties was 0.9%. Striking feature was recognized in the thirties where incidence of early carcinoma was 51.3% the highest in this series. Since the populations of thirties are excluded from the mass survey in this country, it was strongly suggested from the present study that the thirties should be included in the gastric-mass-survey. Another interesting feature observed in the early gastric carcinomas of the thirties was that excavated type predominated comprising 86.7% as compared to the other age groups. Since the age of thirties can not be considered as less risky generation for gastric carcinoma any more, whenever the patient with epigastric pain or pyrosis, commonest symptoms in this series, comes to seek for medical advice, "on-the-spot endoscopy" and biopsy should be made with particular attention to the excavated lesions.
