TWO MAJOR HISTOLOGICAL TYPES OF GASTRIC CARCINOMA AMONG THE FIXED POPULATION OF HIROSHIMA AND NAGASAKI

Abstract

Lauren's histological classification of gastric carcinoma based on the presence of either intestinal or diffuse type was applied to autopsy cases in the fixed population sample of Hiroshima and Nagasaki for 1961-1969. The intestinal type was chiefly seen in older persons and the diffuse type was more frequent in younger persons, especially in women. The ratio of the intestinal type to the diffuse type in Japan was compared with this ratio for high or low risk areas in other countries. The trend of this ratio was similar to that in other cities. There was no statistically significant relation between the occurrence of either type of gastric carcinoma and radiation exposure.
