Total 211 lesions of stomach cancer were collected from the pathology department of the Pusan Paik Hospital during 1979 and 1985. Statistical analysis was carried out showing the following findings; 1) Among the total 211 cancers, male 139 and female 72. The male-female ratio is 2:1. 2) Average age is 52 years, male 54.7 and female 47.5 years old. These figures are 7 years lower than Japanese, and 4 years lower than Americans, clearly suggesting higher carcinogenic agents present in the Korean environment (food). 3) The size of the gastric cancer is 2-5 cm in diameter in the majority of the cases. Those of female are 0.6 cm larger in the average diameter than those of male. 4) The site of the cancer is antrum in half of all cases, the next is body and pylorus. 5) Depth of cancer invasion into the gastric wall shows the serosa the most frequent, 37.4%, the next is subserosa, 28.4%. There was the Early Gastric Cancer in 11% among all cancers of the stomach. 6) Metastasis of the regional lymph nodes was found in 66.8%. The frequency of the metastasis is increasing proportionally with the size of the cancer and the depth of the cancer invasion in the gastric wall. 7) Histopathology of the stomach cancer shows in the following order; poorly differentiated(38.4 %), moderately differentiated(22.7%) and well differentiated(18.5%). Together of these three types consist of 80% of total lesions. There is a distinct difference between male and female on the histological types, for there are 52% in undifferentiated and 48% in differentiated types among male while 72% and 28% among female groups. In average, they are 60% and 40%, respectively. 8) Prominent infiltration of lymphocytes in the stroma is found 2-5% of the cancers. Promenent proliferation of fibrous connective tissue of the stroma is found in 3-9% of the cancers. 9) The distinct difference in female group such as lower age group and more frequent association with undifferentiated form, will be elucidated by genetic disposition, and should be tested by tissue typing. 10) The histopathological classification should be as those of the traditional detailed description of the histopathological types. It will be much benefitcial having a standard classicfication adopted by all institutes of Korea such as the currently adopted method of japanese institutes
