In the era of personalized medicine, epidermal growth factor receptor (EGFR) inhibition with tyrosine kinase inhibitor (TKI) has been a mainstay of treatment for non-small cell lung cancer (NSCLC) patients with an EGFR mutation. Acquired resistance, especially substitution of methionine for threonine at position 790 (T790M), which has accounted for more than half of the cases, developed inevitably in patients who were previously treated with EGFR-TKI. At present, there is no standard treatment for patients who have developed a resistance to EGFR-TKI. Several strategies have been developed or suggested to treat such patients. This article aimsto review the EGFR-TKI re-treatment strategy and the efficacy of different generations of EGFR-TKIs in patients with acquired resistance to prior EGFR-TKI.
在个性化医学时代,表皮生长因子受体(EGFR)抑制剂与酪氨酸激酶抑制剂(TKI)的联合治疗已经成为 EGFR 突变的非小细胞肺癌(NSCLC)患者的主要治疗方法。获得性耐药,尤其是第 790 位苏氨酸被蛋氨酸取代(T790M),已成为先前接受 EGFR-TKI 治疗的患者不可避免的问题,其占比超过一半。目前,对于 EGFR-TKI 耐药的患者,还没有标准的治疗方法。已经开发或提出了几种策略来治疗此类患者。本文旨在综述 EGFR-TKI 再治疗策略以及不同代 EGFR-TKIs 在 EGFR-TKI 获得性耐药患者中的疗效。
