Abstract: Objective. To clarify the current status and problems of screening for lung cancer in Nagasaki Prefecture. Methods. Study-1: The results of lung cancer mass screening by chest radiography and sputum cytology for 6 years between 2001 to 2006 were analyzed. Study-2: All municipalities in Nagasaki Prefecture received questionnaires entitled "Checklist for screening project evaluation" and "Investigation report", in order to evaluate the quality of lung cancer screening conducted in 2006. Results. Study-1: A total of 422,622 participants were screened during 6 years, and 308 patients with lung cancer were detected (detection rate 72.9/100,000). There were 156 (51%) clinical or pathological stage I cases among the 308 patients. Study-2: The participation rate was 20.1% for lung cancer screening conducted in 2006; the proportion of cases requiring detailed examination was 4.8%, and percentage of cases receiving detailed examination was 78.6%. The lung cancer detection rate was 0.08%, and the positive prediction value (PPV) was 1.7%. Satisfactory quality control of mass screening was not necessarily performed in each municipality. Conclusions. Controlling the quality of mass lung cancer screening and achieving a higher participation rate are necessary to realize a effective lung cancer screening. Officials responsible for lung cancer screening should assign mass screening to the appropriate institution with a view to high accuracy. It is also necessary for the screening agency to raise the detection rate of clinical stage I cases. Furthermore, it is necessary to increase understanding about the importance of quality control by informing the inhabitants of Nagasaki Prefecture about screening accuracy.
