Chronic Obstructive Pulmonary Disease Patients Receiving Immunotherapy for Lung Cancer: A Population-Based Study in Canada

Outside of clinical trial eligibility criteria, there is limited data to guide the selection of patients with non-small cell lung cancer (NSCLC) for immune checkpoint inhibitor (ICI) therapy. Chronic obstructive pulmonary disease (COPD) and lung cancer are associated, independent of smoking history, with a common background of chronic inflammation. Previous studies have demonstrated that COPD is a negative prognostic marker for NSCLC, but the clinical benefit of ICI in patients with NSCLC and COPD is unknown.
