The serum levels of carcinoembryonic antigen (CEA), carbohydrate antigen 19-9 (CA19-9), CA125 are often increased in interstitial lung disease patients.~This study was undertaken to investigate the source of these serum tumor markers.We hypothesis that these tumor markers are released from the lung.~The broncholveolr lvge fluid levels of carcinoembryonic antigen (CEA), carbohydrate antigen 19-9 (CA19-9), CA125 were measured in the interstitial lung disease patients before lung transplantation. The immunohistochemical test was performed in the specimen lung after lung transplantation.
