Patients with non-small cell lung cancer (NSCLC) who harbor anaplastic lymphoma kinase (ALK) gene rearrangements can derive significant clinical benefit from ALK tyrosine kinase inhibitor. Accurate patient identification is absolutely crucial for successful using ALK inhibitor treatment. However, lung cancer patients with ALK gene rearrangement after ALK inhibitor therapy eventually develop acquired resistance to treatment. In this review, the authors summarize the clinicopathologic features of ALK-rearranged NSCLC and the pros and cons of current diagnostic testing. In addition, we discuss the current diagnostic flow of ALK testing and consideration of rebiopsy sample during disease progression in patients treated by ALK inhibitors.
非小细胞肺癌(NSCLC)患者如果存在间变性淋巴瘤激酶(ALK)基因重排,可以从 ALK 酪氨酸激酶抑制剂中获得显著的临床获益。准确识别患者对于成功使用 ALK 抑制剂治疗至关重要。然而,ALK 抑制剂治疗后发生 ALK 基因重排的肺癌患者最终会对治疗产生获得性耐药。在这篇综述中,作者总结了 ALK 重排 NSCLC 的临床病理特征以及当前诊断检测的优缺点。此外,我们还讨论了在接受 ALK 抑制剂治疗的患者疾病进展期间,ALK 检测的当前诊断流程以及重新活检样本的考虑因素。
