Lung cancer represents one of the most prevalent malignant tumors globally, and its treatment has entered the era of targeted therapy. The epidermal growth factor receptor (EGFR) mutation is a common type of genetic mutation in non-small cell lung cancer (NSCLC), while c-ros oncogene 1 receptor tyrosine kinase (ROS-1) fusion mutation is a rare mutation site. Currently, there are few case reports on the coexistence of EGFR and ROS-1 gene mutations. This study reports a case of NSCLC with coexisting EGFR and ROS-1 gene mutations, aiming to provide relevant treatment strategies for clinical practice.
