Lung cancer incidence, mortality and survival rate in Korean Elderly Pharmacoepidemiologic Cohort(KEPEC) in 1994-1998 / 한국역학회지

ABSTRACT

PURPOSE: This study was conducted to estimate incidence, mortality and survival rate of lung cancer in the elderly people in Korea. METHODS: Study population was Korean Elderly Phamacoepidemiologic Cohort (KEPEC). The lung cancer incidence cases were detected from three different sources, medical utilization database of the Korea Medical Insurance Corporation (KMIC), the database from the National Cancer Registry, and the database from the Regional Cancer Registry. The hospital survey to confirm the final diagnosis of the potential cases was conducted. A specialist on lung cancer reviewed the abstracted data to confirm the final diagnoses. The lung cancer death cases were detected from the mortality database at National Statistical Office. Incidence rate, survival rate and mortality rate of lung cancer and their 95% confidence intervals were estimated with SAS Window ver. 8.1. PESULTS There were 213 confirmed lung cancer cases in KEPEC between Jan. 1994 and Dec. 1998. Age-standardized incidence rate of lung cancer to the Korean population was estimated to be 316.9 per 100,000 person-years in male and 65.2 per 100,000 person-years in female. Age-standardized mortality rate of lung cancer to the Korean population was estimated to be 342.3 per 100,000 person-years in male and 84.8 per 100,000 person-years in female. One year survival rate was 17% in male and 11% in female. Two year survival rate was 2% in male and 4% in female. CONCLUSION: Age-standardized incidence rate, age-standardized mortality rate and survival rate of lung cancer in the elderly Korean may be useful for further study and making health policy for managing lung cancer in the elderly.
