Checkpoint inhibitors represent the first therapeutic class to replace chemotherapy lines for the treatment of metastatic non-small cell lung cancer (NSCLC), due to improved overall survival and tolerability. Nivolumab, a fully human anti-programmed cell death-1 immunoglobulin G4 monoclonal antibody, is the first immune checkpoint inhibitor approved by the US Food and Drug Administration in 2014 for cases of metastatic melanoma and in 2015 for cases of squamous cell lung cancer and kidney cell cancer. The present study aimed to identify predictive markers (favorable or unfavorable) for time to treatment discontinuation using nivolumab in the second or subsequent line of therapy of metastatic NSCLC cases. Analysis of a group of 78 NSCLC patients treated with nivolumab allowed the identification of negative predictive markers, related to the presence of metastases (adrenal in men under 65 years, liver, brain and the number of metastatic sites) and the hematological profile (neutrophilia at the initiation of treatment and lymphocyte variation at 6 weeks of treatment).
