For studies on the gastric carcinoma in the Chungnam area, the operation specimens were collected at the Department of pathology, Chungnam National University School of Medicine from January 1979. to December 1981, and analyzed the patient´s age and sex, size and location of the lesion, and the gross and histological types. The results were as follows;
1. The total number of gastric carcinoma for 3 years were 280 cases, which were 110 cases (48%) in 1979, 72 cases (42.9%) in 1980, and 98 cases(46.4%) in 1981.
2. Among 280 cases the male cases were 189 (67.5%) and the females 91 (32.5%), and the ratio between male and female was 2. 1 to 1.
The mean age of the patients was 50.8 in the male cases and 50.2 in the female, and the age distribution was the highest in the 6th decade in both sexes.
3. The average diameter of the lesions was 5.1cm and the most frequent size distribution was in the range of 2.0~5.9cm, in which 194 cases (69.3%) were included.
4. The most common location was the antrum; 98 cases (51.9%) in male and 43 cases (47.3%) in female, and the lesser curvature, 161 cases (57.5%).
5. The ulcerative type was the most frequent, 157 cases (38.1%) in male and 74
cases (81.3%) in female, there was no specific relationship between the gross type and age.
6. The adenocarcinoma was the most frequent histological type in both sexes, 145 cases (76.7%)in male and 59 cases (64.8%) in female.
The less frequent type was diffuse carcinoma, and mucoid adenocarcinoma was infrequent, and the adenosquamous carcinoma was very rare.
7. In relationship between the gross types and the histological types, the adenocarcinoma
was the most common type, 167 cases (72.3%) in the ulcerative type, 27 cases (84.4% in the fungating type, and 8 cases (80%) in the superficial spreading type. But, in the diffuse infiltrating type the diffuse carcinoma was more frequent, 4 cases (57. 1%), than the adenocarcinoma.
