Clinical features and therapeutic options in non-small cell lung cancer patients with concomitant mutations of EGFR, ALK, ROS1, KRAS or BRAF

Background: Although oncogenic driver mutations were thought to be mutually exclusive in non-small cell lung cancer (NSCLC), certain tumors harbor co-occurring mutations and represent a rare molecular subtype. The evaluation of the clinical features and therapeutic response associated with this NSCLC subtype will be vital for understanding the heterogeneity of treatment response and improving the management of these patients. Conclusion: In this study, concomitant mutations were found in 1.7% of the NSCLC. EGFR-TKI therapy was more effective than chemotherapy for patients harboring EGFR concomitant mutation, and ROS1 concomitant mutations were more frequent in male patients. For patients harboring coalterations with an ALK or ROS1 rearrangement, we should be cautious when considering the therapeutic options. READ ARTICLE
