Lung cancer continues to be the leading cause of cancer death worldwide, and non-small cell lung cancer (NSCLC) is the most common type of lung cancer. Molecular targeted therapy is the most promising development part in the treatment of NSCLC. In recent years, more and more attention has been focused on some new molecular targets in NSCLC, such as echinodem microtubule-associated protein-like4/anaplastic lymphoma kinase (EML4-ALK) fusion gene. This review will focus on the basic structure, clinicopathologic features, detection method, ALK inhibitor and therapeutic meaning of EML4-ALK in NSCLC.
世界范围内肺癌位居所有癌症致死的第一位，其中大多数为非小细胞肺癌（non-small cell lung cancer, NSCLC）。目前，分子靶向治疗是NSCLC的治疗中最有发展前景的部分。近年来，NSCLC新的分子生物靶点例如棘皮动物微管相关类蛋白4与间变性淋巴瘤激酶融合基因越来越受到关注。本文旨在介绍EML4-ALK融合基因的基本结构、临床病理学特征、检测方法、ALK抑制剂及其在NSCLC治疗中的意义。
