Abstract
ALK基因重排在非小细胞肺癌(non-small cell lung cancer, NSCLC)中发生率约3%-5%。第一代ALK酪氨酸激酶抑制剂Crizotinib可以有效地针对这些肿瘤在NSCLC个体化靶向治疗中发挥重要作用。随机Ⅲ期临床研究对比了Crizotinib和二线标准化疗方案治疗ALK阳性晚期NSCLC患者的疗效,提示Crizotinib治疗ALK阳性的晚期NSCLC患者疗效明显、耐受性好。然而,尽管治疗初期有较好的疗效,但大部分患者持续用药后会出现获得性耐药。因此,一些针对ALK阳性的NSCLC患者的新治疗策略在临床试验中逐步开展,包括第二代ALK抑制剂,比如LDK378、CH5424802(RO5424802)和AP26113等,以及其他靶点抑制剂如热休克蛋白90抑制剂等。本文就ALK阳性NSCLC患者的治疗进展以及最新药物临床研究做一综述。
