EML4-ALK与EGFR基因突变共存型非小细胞肺癌研究进展

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.
