抄録

In our Hospital (inpatients), operated case of gastric cancer were 80 cases during three years since 1954, possible resection were 51 cases of them. Among these 51 resected cases, I -II grade of early gastric cancer were found at the rate of 3.9% (2 cases), III were 9.8% (5 cases) and IV were 27.4% (14 cases). Otherwise operated cases of gastric cancer were 36 cases in gastric mass screening during six years since 1956, early gastric cancer were respectively 6.7% (2 cases), 20% (6 cases) and 40 % (12 cases) in proportion to 30 resected cases of them. Therefore discovery f requence of early gastric cancer was two times as much as our Hospital (inpatients) in gastric mass screening. The histo-pathological classification of those early gastric cancer was as follows. Adenocarcinoma was in the majority of them. That f requence decreased in order of mucinous carcinoma, anaplastic cancer and gallert carcinoma. In comparison with the treated case at our ho-spital and : at gastric mass screening, discovery frequency of early gastric cancer at the later was more much than at the former, more-over there were a .few of subjective symptome, abdominal findings and other clinical findings in such a case. The original place of early gastric cancer was seen in antrum, for the most part, lin addition, tumor types was seen more mainly than others, ulcer types largely in corpus.
