Abstract
PDF - OBJECTIVES
A method of estimation using 8 population-based cancer registries databases in Korea (KRCR DB) has been introduced as another strategy for validly estimating the national cancer incidence (NCI) in Korea. The purpose of this study was to evaluate the validity of this method with using the 7 KRCR DBs, excluding Seoul covering 21% of the total population of Korea. METHODS: We designed the study method (NCSE_7) as same as the estimating method with using 8 KRCR DBs (NCSE_8) in order to ensure maximal comparability. We defined the expected number of cancer cases in each registry as the number of observed cases and then we added the weighted observed cases according to gender, age and the proportion of the population covered by each registry for the population of the seven regions and the population of all areas, with excluding these seven regions. From the expected number of total cancer incidents, the estimated NCI was calculated by dividing the expected number of cancer cases by the number of the total population. The standard error (SE) of the estimated incidence was also taken from the expected number of total cancer incidents. RESULTS: Compared with the results of the NCSE_8, the overall age-standardized rates (ASR) in men and women became over-estimated and under-estimated, respectively. Primary sites that showed statistically significant differences were the colo-rectum, prostate, breast and thyroid. The index of death certificate only (DCO)and microscopically verified (MV)% indicating levels of data quality were decreased, especially for the brain in DCO% and kidney in the MV%. CONCLUSIONS: The database of Seoul regional cancer registry has a key role for the method to estimate the valid nationwide cancer statistics in Korea with using the population-based cancer registries' databases. -

- OBJECTIVES
Valid data on the national cancer incidence (NCI) is the data should be needed to plan, monitor and evaluate the national cancer control programs. The purpose of this study was to estimate the NCI for 2000-2002 from 8 population-based cancer registries database in Korea (KRCR DB). METHODS: We defined the expected number of cancer cases in each registry as the number of observed cases and then adding to the weighted observed cases, according to sex, age groups, and the proportion of the population covered by each registry for the population of the eight regions and the population of all areas with excluding the 8 regions. From the expected number of total cancer incidents, the estimated NCI was calculated by dividing the expected number of cancer cases by the number of the total population. The standard error (SE) of the estimated incidence was also taken from the expected number of total cancer incidents. RESULTS: The overall estimated crude rates in 2000-2002 were 267.1 and 219.0 per 100,000 for men and women, respectively. The overall age-standardized rates (ASR) were 290.1 and 180.7 per 100,000, respectively. Compared with the ASRs obtained from Korea National Cancer Incidence database (KNCI DB), the estimated ASRs from the KRCR DB did not show statistically significant differences except for some cancers in women. For the aspect of the SE, index of DCO(death certificate only) and of MV(microscopically verified), the estimated ASRs from the KRCR DB are more accurate and they have higher quality rather than the calculated ASRs from the KNCI DB. CONCLUSIONS: We found that this developed method using the KRCR DB is valid and it could be another strategy for estimating the NCI in Korea. -

Abstract

- To estimate the incidence of uterine cervix cancer among Korean women, we have conducted a study using the claim data on the beneficiaries of Korea Medical Insurance Corporation(KMIC). All medical records of the potential cases with diagnosis of ICD-9 180, 181, 182, 199, 219, 233 in the claims sent by medical care institutions in the whole country to the KMIC from January 1988 to December 1989, were abstracted and Gynecology specialist reviewed the records to identify the new cases of uterine cervix cancer among the potential cases during the corresponding period. Using these data, the incidence of uterine cervix cancer among Korean women was estimated as of July 1, 1988 to June 30, 1989. The crude rate was estimated to be 17.34(95% CI: 16.76~17.92) per 100,000 and the cumulative rates for the ages 0~64 and 0~74 were 1.7% and 2.2%, respectively. The age-adjusted rate for the world population was 19.93 per 100,000 which was higher than those of other Asian countries including China and Japan in 1983~1987. The truncated rate for ages 35~64 was 52.05 per 100,000 which was one of the highest in the world. With increasing age, the incidence rate increased to 78.11 per 100,000 in women aged 55~59 years, then it decreased in the older groups. This finding suggests that detecting rate of uterine cervix cancer may decrease in women aged 60 years or older due to detecting rate of uterine cervix cancer may decrease in women aged 60 years or older due to inadequate medical care seeking behavior. In the geographical area, the SIR of Jeju province was significantly low but it might be due to statistical unstability by small case numbers.

Abstract

- Exploring the epidemiological trend of HIV/AIDS is required for making the national AIDS policy. In this study, the trend of HIV/AIDS incidence, rout of transmission and some characteristics of AIDS for the past 11 years in Korea using the reported cases from the national STD screening scheme were reviewed. Based on the results, the trend of main route of transmission according to the year was established by stage and the HIV/AIDS cases in this year was estimated and that to the year 2000 was projected by 'Epimodel' programme. The results were as follows. 1. Of the total infected persons, 76% were in their twenties and thirties, socioeconomically and sexually active age groups while the transmission by sexual contact overseas was decreasing, the infection through domestic heterosexual and homosexual contact was increasing. 2. In the middle of the 1980's, the infected persons were mainly prostitutes infected through heterosexual contact with the HIV positive foreigner in this county(stage l). And in the late of the 1980's the main source of infection was the sexual contact overseas and the domestic heterosexual contact(stage 2). Since the early of the 1990's, the infection through the heterosexual contact with non-regular sexual partner in this country has increased rapidly(stage 3), which was the evidence of the possibility of HIV epidemics. After that, it was expected that the infection through the homosexual contacts, the heterosexual contacts with commercial sex workers outside and the non-regular sexual contact inside of this county would increase continuously. In the result, the occurrence of neonatal infection by vertical transmission was expected(stage 4). 3. The number of HIV/AIDS was estimated at 572 to 2,313 and the projected number of HIV/AlDS to the year 2000 was around 5,800 including 627 AlDS patients. For the further study on the estimation and projection of HIV/AIDS, it was suggested that the sampling survey on the HIV infection rate in the high risk groups and the sentinel hospital surveillance system should be conducted.
