Epidemiologic characteristics of cancer mortality and morbidity among Koreans
Joung Soon Kim
Cancer has been a major cause of death among Koreans since 1970’s. This study was carried out to characterize the cancer occurrence among Koreans by analyzing mortality and morbidity data. The source of data on cancer mortality is annual reports on the cause of death statistics produced by National Bureau of Statistics, EPB Korea and annual World Health Statistics; on morbidity of cancer is prevalence survey of 1987 for the populations of six health insurance demonstration project areas. Mortality rate and prevalence rate per 100,000 population were plotted on the semi-logarithmic paper by cancer site, sex and age groups for comparison. Observed results are as followings: 1. Mortality rates per 100,000 caused by all sites cancer among Koreans in 1985 were 95.0 for males and 54.7 for females which were much lower than that of Japanese males(191.1)and females(126.9). 2. The most frequent cancer site causing death was in order of stomach, lung, esophagus, leukemia and larynx for male, and in order of stomach, uterus(part unspecified), lung, leukemia and breast for female; malignant neoplasms of rectum and rectosigmoid, liver(primary), bladder, lung, prostate, female breast and uterine cervix were much lower among Koreans when compared with Japanese and USA populations. 3. The mortality age curves of various cancer for Koreans, in which the mortality rates were higher among younger age groups and much lower among older age groups(over 65-year of age)than those of Japanese and USA populations, suggested that the effort to make valid diagnosis for older ages was lacking. 4. Age adjusted prevalence rate of all site cancer per 100,000 was 225 for male and 189 for female; the prevalence of cancer strikingly increased from 35-44 years old age group up to 65-74 years group tappering off after the age 75-year. 5. The four major cancer site in the prevalence study data were stomach(33.3%), lung(13.1%), liver and intrahepatic bile duct(12.5%) and lymphatic & hematopoietic tissue(6.8%)for male; stomach(19.8%), uterine cervix(15.9%), breast(7.2%) and liver(6.7%) for female. The frequency distribution of the cancer by site was quite similar to other studies such as Kang-wha cancer registry and hospital admission study on cancer patients among policy holders of Korean Medical Insurance Corporation. 6. The prevalence rates of cancer occurred almost every site were higher among males than females, and the age curves of the prevalence were almost identical to that of mortality data.
