RESUMO
With the development of precision medicine for lung cancer, targeted therapy has greatly improved the survival and prognosis of patients with advanced non-small cell lung cancer (NSCLC), but the occurrence of acquired drug resistance ultimately leads to patients with no targeted drugs available and no standard treatment options for this group of patients afterwards. The emergence of immune checkpoint inhibitors (ICIs) has revolutionized the treatment of advanced NSCLC. However, due to the unique features of NSCLC with epidermal growth factor receptor (EGFR) mutation, such as immunosuppressive tumor microenvironment (TME), single ICIs treatment has limited clinical benefits in NSCLC patients with EGFR mutation, and the combination of ICIs with chemotherapy and/or targeted therapies is the trend. This review further discusses potential subpopulations with EGFR mutations that may benefit from ICIs treatment, and analyzes how decisions can be made in the era of combined immunotherapy to maximize the efficacy of ICIs treatment in EGFR mutation targeted therapy for NSCLC patients with drug resistance, with the aim of achieving individualized treatment.
