    AbstractIt has been found that occurrence of immune-related adverse events (irAEs) is associated with outcome in the treatment of advanced non-small-cell lung cancer (NSCLC) with anti-programmed cell death (PD)-1 or anti-PDL1 agents. Independent correlation with survival was not consistently demonstrated and correlation with the number of toxicities was also not previously described. All patients treated with nivolumab for advanced NSCLC, in the second line setting, were retrospectively reviewed in a single-center from March 2015 to March 2017. Sixty-nine patients were identified. After a median follow-up of 13 months (95% CI: 10.8; 15.3), there were 46 tumor progressions and 37 deaths. The 6-month and one-year progression-free survival (PFS) and overall survival (OS) rates were 29%/61% and 24%/49%, respectively. Thirty-one patients (44.9%) presented irAEs. Patients presenting tumor response to previous chemotherapy had a higher rate of irAEs (P=0.01) and a better OS (HR=2, P=0.04). Occurrence of irAEs correlated with OS in multivariate analysis (HR=0.4, 95% CI [0.19; 0.8], P=0.02). The number of irAEs correlated with tumor response, PFS and OS in univariate analysis. Having≥2 irAEs correlated with better outcome compared with one irAE, which correlated with better tumor response and PFS in comparison with 0 irAE, in multivariate analysis. In this study, irAEs was associated with a better outcome in patients treated with nivolumab for advanced NSCLC in the second line setting. Interestingly, the number of irAEs correlated with tumor response and PFS.Copyright © 2020 Société Française du Cancer. Published by Elsevier Masson SAS. All rights reserved.
