Lung cancer is one of the most prevalence malignances, of which non-small cell lung cancer (NSCLC) account for 80%-85% of lung cancer. Molecular target therapy is one of the most popular and promising field of NSCLC treatment, and its hotspots includes EGFR (epidermal growth factor receptor), EML4-ALK (echinoderm microtubule associated protein like4-anaplastic lymphoma kinase), etc. Former researches indicated that EML4-ALK fusion and EGFR mutation were excluded mutually. However, cases of patients harbored concomitant EML4-ALK fusion gene and EGFR mutation have been reported continuously at recent. This review aims to summarize the incidence and molecular structure of EML4-ALK fusion gene and EGFR mutation, as well as clinical features of patients with the concomitant genes induced NSCLC.
肺癌是最常见的恶性肿瘤之一，其中非小细胞肺癌（non-small cell lung cancer, NSCLC）占肺癌的80%-85%。分子靶向治疗是目前NSCLC最热门也是最具前景的领域之一，其中的热点分子包括表皮生长因子受体（epidermal growth factor receptor, EGFR）、棘皮动物微管样蛋白4-间变淋巴瘤激酶（echinoderm microtubule associated protein like4-anaplastic lymphoma kinase, EML4-ALK）等。既往研究认为EML4-ALK融合基因与EGFR突变不能共存。近期陆续报道了EML4-ALK融合基因与EGFR突变共存的病例。本文就EML4-ALK融合基因及EGFR突变基因的分子结构、发生率和目前已报道双突变患者的临床特点等进行综述。
