Coexistence of Emphysema With Non-small-cell Lung Cancer Predicts the Therapeutic Efficacy of Immune Checkpoint Inhibitors

In Vivo. 2021 Jan-Feb;35(1):467-474. doi: 10.21873/invivo.12280.

Abstract

Background/aim: Chronic obstructive pulmonary disease coexisting with non-small-cell lung cancer (NSCLC) was reported to be associated with a longer progression-free survival (PFS) in patients treated with immune checkpoint inhibitors (ICIs). In the present study, we investigated the impact of emphysematous change on the treatment response to ICIs in patients with NSCLC.

Patients and methods: A total of 153 patients with advanced NSCLC who received ICIs (nivolumab, pembrolizumab, or atezolizumab) at our hospital from January 2016 to May 2019 were retrospectively enrolled.

Results: According to the Goddard scoring system, 71 (46.4%) patients were classified as having emphysema and 82 (53.6%) as having no emphysema. Multivariate analysis showed that a good performance status and coexisting emphysema (hazard ratio=0.49; 95% confidence intervaI=0.28-0.84; p=0.010) were independent predictors of a better PFS.

Conclusion: Recognizing emphysema coexisting with NSCLC may help predict the therapeutic efficacy of ICIs in such patients.
