Abstract | Background: Objectives: This prospective study aimed to investigate whether inhibition of the PD-1 axis altered lung inflammation and pulmonary function in NSCLC patients with and without COPD. Method: This was a prospective multi-center study. Measurements of fractioned exhaled nitric oxide (FeNO) and pulmonary function were performed before and after 4 cycles of nivolumab therapy. Results: A total of 137 patients with NSCLC were initially enrolled, and subsequently 95 patients (41 COPD and 54 non- COPD) receiving 4 cycles of nivolumab administration were included. After anti-PD-1 therapy, FeNO levels were significantly elevated together with increase in peripheral eosinophils. Interestingly, significant FeNO elevation was only found in COPD patients without increased peripheral eosinophils, but this was not the case in non- COPD patients. Additionally, COPD patients exhibited significant increases in FVC and FEV1 but no changes in dyspnea scales, and acute exacerbation did not occur during the therapy. Conclusion: Our observations suggest that anti-PD-1 therapy changed FeNO levels and pulmonary function in NSCLC patients. This therapy does not worsen COPD in terms of symptoms, pulmonary function, or acute exacerbation.
