表皮生长因子受体酪氨酸激酶抑制剂(epidermal growth factor receptor-tyrosine kinease inhibitors,EGFR-TKIs)对EGFR敏感突变非小细胞肺癌(nonsmall cell lung cancer,NSCLC)除了其卓越的疗效,也如其他药物一样最终不可避免地发生耐药.EGFR基因突变是最常见的肺癌驱动基因之一,针对EGFR-TKI耐药后的处理,目前虽无固定治疗模式,但临床进行了大量的探索性研究及治疗对策的探讨,部分结果对临床治疗这类患者有一定启示.本文将就近年具有代表性的研究及进展做一论述.%Epidermal growth factor receptor tyrosine-kinase inhibitors (EGFR-TKIs) have elicited curative effects on patients with advanced non-small cell lung cancer and with activating mutations in the EGFR gene. However, acquired resistance to EGFR-TKIs is eventually developed after an initial response is induced;as such, patients with acquired resistance must be treated with more ef-fective strategies to delay or possibly overcome the resistance. This article reviews available data on the treatment of patients who have failed to respond to EGFR-TKI.
