RESUMO
Cell epidermal growth factor receptor (EGFR) mutation is one of the causes of non-small cell lung cancer (NSCLC). The emergence of targeted drugs for EGFR gene mutation provides a new direction for NSCLC treatment. The common EGFR-targeted drugs like the first-generation gefitinib and erlotinib, the second-generation afatinib and the third-generation osimertinib have shown their good efficacies in a number of large international clinical trials. EGFR gene mutation in Chinese NSCLC patients is different from that in European and American NSCLC patients. This paper briefly reviews the characteristics of EGFR gene mutation and the current status and progress of EGFR-targeted drugs in Chinese NSCLC patients to investigate the mutation characteristics of EGFR in Chinese NSCLC patients and the response as well as prognosis of Chinese patients to EGFR-TKI therapy.
