Current status of first-line treatment with pembrolizumab for non-small-cell lung cancer with high PD-L1 expression.

ABSTRACT: It is not clear whether pembrolizumab monotherapy (MONO) or pembrolizumab plus platinum-based chemotherapy (COMB) should be selected for patients with advanced non-small-cell lung cancer (NSCLC) exhibiting high PD-L1 expression (tumor proportion score ≥ 50%).
