Epidermal growth factor receptor (EGFR) mutations are common driver genes in nonsmall-cell lung cancer and have different sensitivities to EGFR-tyrosine kinase inhibitors (EGFR-TKIs). EGFR is divided into classic mutations and rare mutations. Classic mutations are well known, but the understanding of rare mutations is not sufficient. In this article, we summarize the clinical research and treatment progress of rare mutations for different EGFR-TKIs and provide a basis for clinical treatment decisions.
Keywords: EGFR mutations; EGFR-TKIs; nonsmall-cell lung cancer (NSCLC); rare mutation; targeted therapy.
