ABSTRACT

EGFR-tyrosine kinase inhibitors (EGFR-TKIs) had been regarded as the front-line treatment for advanced non-small-cell lung cancer (NSCLC) patients with EGFR mutations. However, resistance to EGFR-TKIs is inevitable, it remains a major challenge. Immune checkpoint inhibitors (ICIs) had shown superior clinical efficacy in many types of solid tumors, while it exhibited impaired overall efficacy in NSCLC with EGFR mutations. In this review, we will perform a meta-analysis to assess the relationship between the programmed death ligand 1 (PD-L1) expression and clinical benefit of EGFR-TKIs. We also overview the immunotherapy in advanced NSCLC patients with EGFR mutations to investigate the potential biomarkers predicting the ICIs efficiency, and the subgroups that could benefit from ICIs treatment.
