Abstract:
Epidermal growth factor receptor (EGFR) gene is one of the most common driving genes in non-small cell lung cancer patients, and immune checkpoint inhibitors (ICIs) have been controversial in the clinical application of non-small cell lung cancer with EGFR mutant. The expression abundance of programmed death ligand 1 (PD-L1) is an important predictor to guide the application of ICIs, and EGFR mutations may affect PD-L1 expression in tumor cells. Recent clinical studies have pointed out that the single drug of ICIs is not effective in patients with EGFR mutation, however, the combination of ICIs combined with chemotherapy and the four drugs proposed in the IMpower150 trial show good clinical benefits. In addition, the safety of ICIs and epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) combination model needs to be further clarified.
