Four hundred seventy nine male patients, aged over 60 were admitted to the tuberculosis ward of Kinki National Central Hospital for Chest Diseases between Jan. 1975 through Dec. 1979. On their admission, cytological screening of their sputum was performed for 3 consecutive days.<BR>As a result, 13 cases of bronchogenic carcinoma were found (2.7%). The Incidence (prevalence) rate of bronchogenic carcinoma was much higher than that calculated from the number of deaths due to bronchogenic carcinoma among the same age group according to the population study of Ministry of Health and Welfare.<BR>Histological types were epidermoid carcinoma in 11, adenocarcinoma in one, and small cell car-cinoma in another one. All patients had history of smoking, and BI was over 1, 000 (cigarettes/day years) in 9 patients.<BR>Their chest X-ray apparently showed evidence of pulmonary tuberculosis, and 9 of them were positive with tubercle bacilli. Other 2 cases were positive for mycobacteria other than tubercle bacilli. The other two were negative both on smear and culture.<BR>As for the site of bronchogenic carcinoma, it was more often found in the same side of tuberculosis lesion.
