Relationship Between Emphysema Severity and the Location of Lung Cancer in Patients With Chronic Obstructive Lung Disease

Abstract

Lower emphysema grades and reduced FEV1/FVC seemed to be independent predictors of central location of lung cancer in COPD. Therefore, in patients with COPD with lower grade emphysema and airway-predominant disease, additional screening tools may have to be considered for central lung cancer detection along with thin-section CT.
