Gastric Carcinoma among Koreans: An Analysis of 1122 Cases
ABSTRACT
The author investigated 1122 consecutive cases of gastric carcinoma which were subjected to the Department of Pathology, College of Medicine, Busan National University for pathological evaluation during the last 10 years from 1968 to 1977. All the specimens obtained either by subtotal or total gastrectomy were referred by the Busan University Hospital and the Busan Gospel Hospital. The author analyzed them statistically in epidemiological and pathological points of view and obtained the following results: 1. No information about the incidence of gastric carcinoma among Koreans during the period could be acquired from the materials studied. 2. The male-to-female ratio was 1.94 to 1. The youngest and the oldest cases were 19 and 78 years of age, respectively. The model age group was 5th decade in both sexes. There was some difference in form and center between the age distributions of gastric carcinoma in male and female. The former was slightly asymmetrical and negatively skewed, while the later was symmetrical and normal in form. The average age of male cases was 51.15 year and that of female cases, 49.37 year. 3. The mortality or morbidity rate increased in both sexes as the age increases and this tendency was more marked in male than in female. 4. There was no significant difference between the gross findings of gastric carcinoma in male and female. The location of the carcinoma was as follows: pylorus and antrum was in 69%, body 9%, cardia 7%, and fundus 1%. Most of the carcinomas were found in the low part of the stomach, especially at the lesser curvature. The sizes of the carcinomas varied greatly. The 1st, 2nd, and 3rd quartiles were 4.3cm, 6.0cm, and 8.4cm, respectively. The gross types of the carcinomas were classified, after Stout, and their relative frequencies were as follows: ulcerative type 66%, diffuse infiltrating 26%, fungating 6%, and early spreading 2%. There was no significant difference between the age distributions by the gross types in male and female, and no significant association between gross types and age. The histological types were classified after Kubo, and their relative frequencies were as follows: adenocarcinoma was in 61%, diffuse carcinoma 36%, and mucoid adenocarcinoma 3%. The distribution of histological types of the series under study did not differ from that of the Kubo’s Kyushu (Japan) series, but did differ from that of the Kubo’s Minnesota (U.S.A.) series. The ratio of adenocarcinoma to diffuse carcinoma increased in both sexes as the age increases. There was a significant association between sex and age in the distribution of adenocarcinorma and diffuse carcinoma. There was no significant difference between the male and female age distributions in both adenocarcinoma and mucoid adenocarcinoma, but a significant difference was found between the male and female age distributions in diffuse carcinoma. The average ages of the patients, if indicated to male and female separatedly, were as fellows: adenocarcinoma 52.6 and 51.7, mucoid Ca 52.5 and 47. 1, diffuse 52.3, and 48.7. There was a significant association between gross and histologic types. On the basis of the results described above, it was suggested that the characteristic features of gastric carcinoma among Koreans might be expressed by the phenomena due to the low average age of the patients. One of the phenomena is, for instance, the relatively high incidence of the histologic type of diffuse carcinoma in younger age.
