In order to obtain the epidemiological feature of cancer in some population in Korea, special surveys were conducted on the mortality of cancer and the sociomedical backgrounds of cancer patients on the basis of correlations between the incidence and mortality of cancer.
As a result, the following conclusions have been reached:
1. The cancer specific death rate as whole was 34.9 per 100,000 population in urban areas and 38.4 in rural areas, and 38.8 for male and 30.9 for female.
2. The cancer specific death ratio was 7.74 percent as a whole and 8.17 per cent in urban areas and 7.19 per cent in rural areas out of total number of deaths.
3. Stomach cancer occupied the greatest proportion of the total number of cancer victims for both sexes: 63.1 per cent for male and 46.8 per cent for female.
4. For female, liver and bile duct cancer was second to uterine cancer which constituted 21.6 per cent of the total number of cancer victims.
The victims of liver and bile duct cancer occupied 14.0 per cent for male and 11.2 per cent for female.
5. Cancer of respiratory organs showed small proportions: 4.9 per cent for male and 2.1 per cent for female.
6. Stomach cancer recorded high percentages: 81.9 per cent for male and 66.5 per cent for female in rural areas, and 49.2 per cent for male and 35.1 per cent for female in urban areas.
Liver and bile duct cancer showed twice as high a percentage in urban areas as in rural areas, contrary a percentage in urban areas as in rural areas, contary to the case of stomach cancer.
7. Generally, male incidence showed a higher rate than female´s except for uterine and breast cancers.
8. Mortality was higher of digestive organ cancer than of respiratory organ cancer as was the case in other oriental countries.
Peculiar in this country, however, was that liver cancer showed a high rate while rectal cancer showed a low rate.
9. An overwhelming proportion of cancer incidence accounted for people in their 40´s or more.
10. The average family size of cancer patients was 6.5 per cent, similar with the traditional average family size in throughout country.
The greatest proportion of cancer patients was constituted by those belonging to families who ahd low occupational, economical and educational status.
11. The average age of the first marriage of cancer patients was 20.0 years. Particularly that of cervical cancer patients was 19.6 years, thereby showing a significant statistical correlation with early marriage.
12. Cancer patients experienced an average of 6.6 times of pregnancy. Cervical cancer patients had an average of 4.9 times of normal deliveries and had experienced an average of 2.9 cases of artificial abortion.
13. Out of those who visited hospital or clinic at the onset of cancer, 25.7 per cent was misdiagnosed, particularly with 27.4 per cent of cervical cancer patients misdiagnosed.
