The Impact of Coexisting COPD on Survival of Patients With Early-Stage Non-small Cell Lung Cancer Undergoing Surgical Resection

摘要

Background:COPD is a recognized risk factor for lung cancer, but studies of coexisting COPD in relation to lung cancer outcomes are limited. We assessed the impact of COPD on overall survival (OS) and progression-free survival (PFS) in patients with early-stage non-small cell lung cancer (NSCLC).
