A comparative study was made of 800 Japanese and 627 American cases of gastric carcinoma which had been surgically resected. The intention was to show if there was a difference in histologic appearance associated with geographic distribution and incidence. In both Japan and the United States adenocarcinoma was the predominant tumor type among the patients over 50 years of age. In patients under 50. years, the predominant tumor was diffuse carcinoma. The proportion of adenocarcinoma to diffuse carcinoma studied in age group from both populations showed no significant statistical difference in the proportionate number of each type. In the high incidence population of Japan, there was a predominance of younger patients, which contained a predominance of diffuse carcinoma.
