Aim: Nivolumab, a fully human IgG4 programmed death 1 (PD-1) immune-checkpoint inhibitor antibody, restores antitumor antibody-disrupting PD-1-mediated signaling. Although it has a striking antitumor efficacy, factors predicting response, especially at the beginning of the immunotherapy are important owing to its side-effect profile and high cost. In this study, we aimed to evaluate the predictive value of the neutrophil-lymphocyte ratio (NLR), derived NLR (dNLR), prognostic nutritional index (PNI), carcinoembryonic antigen (CEA) and change of these parameters during nivolumab treatment in patients with non-small cell lung cancer (NSCLC).
