EGFR and non-small cell lung carcinoma: The purpose of this study was to evaluate the clinical characteristics of NSCLC patients in order to distinguish ALK&ROS1 gene rearrangements, EGFR mutations, and non‐ALK&ROS1/EGFR (no mutations and rearrangements), so as to distinguish these different types, to assist clinicians to assess the NSCLC patients with these genetic abnormalities.
