Comparison of the toxicity profile of PD-1 versus PD-L1 inhibitors in non-small cell lung cancer: A systematic analysis of the literature.

Monoclonal antibodies against programmed cell death protein 1 (PD-1) and programmed death ligand 1 (PD-L1) are effective therapies in patients with non-small cell lung cancer (NSCLC). Herein, the authors performed a systematic review investigating differences in the toxicities of PD-1 and PD-L1 inhibitors.
