Abstract:
      Lung cancer is the leading cause of cancer-related mortality worldwide. Despite great progress in the development of target agents, most people who do not harbor a mutation do not benefit from these agents. Immunotherapy, which stimulates the body’s immune system to improve the anti-tumor immunity effect, is a new therapeutic method for non-small cell lung cancer (NSCLC). Programmed cell death 1 (PD-1) and its ligand (PD-L1) belong to the CD28/B7 immunoglobulin super-family and are co-stimulatory molecules that show negative regulation effects. Combined with its ligand, PD-1 can modulate the tumor micro-environment, enabling tumor cells to escape host immune surveillance and elimination and play a key role in the clinical significance of NSCLC. An increasing number of clinical trials have suggested that immune checkpoint inhibitors, including anti-PD-1 and anti-PD-L1 monoclonal antibodies, are beneficial and safe for NSCLC. Here, we review the brief history of PD-L1 as a biomarker, mechanism of action, and critical role of PD-1/PD-L1 in the treatment of NSCLC as well as the current research status and future directions.
