In recent years, molecular targeted therapy has effectively improved the prognosis of advanced non-small cell lung cancer (NSCLC) patients with driver gene-positive, of which the efficacy is particularly significant for NSCLC patients with human epidermal growth factor receptor gene mutation, echinoderm microtubule-associated protein-4-anaplastic lymphoma kinase fusion gene, ROS1 gene rearrangement,etc. The selection of targeted therapy drugs is particularly important for advanced NSCLC patients with positive driver genes.
