Mesenchymal-epithelial transition factor (MET) has long been considered as the most crucial and promising driver gene in the occurrence and development of non-small cell lung cancer (NSCLC), except for epidermal growth factor receptor (EGFR), anaplastic lymphoma kinase (ALK), and c-ROS oncogene 1 receptor tyrosine kinase (ROS1). This evidence concerns the gene EGFR and non-small cell lung carcinoma.
