Driver mutations are detected in 30–35% of metastatic non-small cell lung cancer (NSCLC) patients, andmutation discordance may occur between biopsies. Therefore, false negative results for a driver mutation are reportedin some patients who may need rebiopsy. We aim to determine a clinicopathological feature (especially tumor localization), other than smoking and gender, that predicts driver mutation in metastatic non-squamous NSCLC.Methods: A total of 75 patients with driver mutation reports were included in the study. The age, gender, smokingstatus, pathology, primary tumor location, and mutation of each patient were evaluated. The relationship between theclinicopathological features and driver mutations was analyzed.Results: The median age of the patients was 66 (range: 36–85); 55 (73%) of the patients were male. A driver mutationwas detected in 23 (30.7%) patients. The rates of EGFR, ALK, and ROS1 were 22.7%, 6.7%, and 1.3%, respectively. Drivermutations were more commonly found in ..... READ ARTICLE
