Japanese residents who are 40 years old or higher can freely receive chest X-ray every year. We utilized this screening system in Chiba City in order to detect COPD. From April 2010 to March 2011, 83,924 participants received regular lung cancer screening by chest X-ray at the first examination centers, which was approximately 30% of objective residents. We set the criteria of suspicious of COPD indicating 60 years or older, positive smoking history and having any chronic respiratory symptoms. 1,170 (1.3%) were recognized as suspicious of COPD and 551 of them (56.2%) received further examination including pulmonary function test (PFT) and/or chest computed tomography (CT) as the second close examination at 39 second examination centers.Results: 138 participants (25.0%) were reported as COPD from the second examination centers and 42.2% of them were necessary for COPD treatment. Only eight participants (5.8%) were already diagnosed COPD before screening. PFT data could be collected from 173 participants, and 43 (24.9%) were diagnosed as COPD (FEV1 less than 70%). Emphysema grades according to Goddard classification on CT revealed that 21.1% was radiological emphysema. One patient with normal chest X-ray was detected lung cancer by CT and could receive curative surgery.Conclusion: COPD screening by using a community-based lung cancer screening program may be effective for detection of COPD. These patients can be treated COPD as early as possible. ER -
