Purpose: This study was carried out to investigate survival mte and the factors affecting survival among lung cancer patients who have been registered in Daejeon Cancer Registry from 1998 to 2000. Methods: Kaplan-Meier method and Cox proportional hazard model were used to evaluate the factors affecting survival of lung cancer patients. Results: Lung cancer was more common in men than women, with an ovemll sex ratio in Daejeon, Korea of roughly 3: 1. The incidence of lung cancer was 17.1 per 100,000 population in 1998, 21.4 in 1999, and 22.4 in 2000. Average age of incidence was 64.8 years old and 11.7% of study subjects having family history of lung cancer. Forty eight % of lung cancer was diagnosed as Stage III and 40.6% as Stage IV. Histologically, squamous cell carcinoma was 39.7% of all and most frequent, and then adenocarcinoma 25.5%, and small cell carcinoma 19.3%. 3-year survival rate of female was higher than that of males, and that of smoker was the lowest among groups according to the smoking level. Survival rate by age fell dramatically in group over 70 years. Lung cancer patients diagnosed as Stage III and Stage IV had a much lower survival rate than those diagnosed as Stage I or Ⅱ Stage, LDH and age were proved to be important variables that affect the mortality of lung cancer patients. Conclusion: We found that the stage at diagnosis was a critical factor that affected the survival of lung cancer patients from this study. So It is essential to develop early diagnosis of lung cancer and then it needs to evaluate the effectiveness of that.

To compare the clinical usefulness of four alcoholism-screening tests frequently used in Korea such as MAST, NAST, AUDIT, CAST, 96 drinking males were given diagnostic interview based on DSM-IV criteria and scores from four tests were obtained and analyzed. Of 96 subjects, 52.1% were normal without drinking problems, 38.5% with alcohol abuse and 9.4% with alcohol dependence. In terms of reliability of items in screening tests, four items in MAST were not found to have statistically significant item-total correlation. The appropriate cut-off value for screening tests to detect alcohol use disorders were above 15 points in AUDIT, above 5 points in MAST, above one item in NAST and above 2 items in CAGE. In terms of sensitivity for detection of alcohol use disorders, NAST was highest with 93.5%, and specificity, CAGE was highest with 90.0%. Considering the lowest sensitivity of 76.0% in CAGE and 76.J% of specificity in MAST, AUDIT and NAST were the most appropriate in screening alcohol abuse. The appropriate standard values for screening alcohol dependence were above 26 pants in AUDIT, above 13 points in MAST, above 5 items in NAST, and above 3 items in CAGE. In screening alcohol dependence AUDIT had the highest sensitivity of 100.0%, and both AUDIT and NAST had the highest specificity of 94.3%, respectively. The sensitivity of three screening tools except AUDIT were the same with the value of 88.9% and therefore AUDIT were the most appropriate in detecting alcohol dependence taking into consideration the relatively low specificity of 85.1% in CAGE.
