Cancer Mortality of the Korean Population in Japan 1968–1977

Abstract

Kim Y S (Department of Environmental Sciences, University of Texas Health Science Center, School of Public Health, PO Box 20186,. Houston, Texas 77225, USA) Cancer mortality of the Korean population in Japan 1968–1977. International Journal of Epidemiology 1984, 13: 11–14. Cancer mortality of the Korean population in Japan for the period 1968–1977 was examined using a standardized mortality ratio (SMR) based on Japanese mortality for 1975. The most frequent site of cancer for Korean males and females in Japan was the stomach but the rate has declined recently for both sexes. Based on deaths from all malignant neoplasms in the period 1973–77, the SMR for all sites among Korean males in Japan was 161 (95% confidence limits—147 and 176), whereas the ratio for Korean females in Japan was 94 (95% confidence limits—81 and 109). Compared with Japanese, Koreans in Japan had a significantly higher SMR for cancer of the liver and trachea-bronchus-lung in both sexes.
