Abstract
Non-small cell lung cancer (NSCLC) patients with oncogenic ROS1 rearrangements would inevitably develop drug resistance and disease progression after receiving targeted oncogene therapy. Here, we present a metastatic lung adenocarcinoma patient harboring a CD74-ROS1 fusion who initially responded to crizotinib and then developed resistance after acquiring a rarely reported BRAF V600E mutation.
