A Case of Lung Adenocarcinoma Harboring a Rare LOC285000-ALK-NCK2 Gene Fusion Identified by Next-Generation Sequencing With Long-Term Response to Crizotinib

Most patients with NSCLC, initially sensitive, will develop resistance after a period of time after the application of ALK inhibitors. We present here a rare LOC285000-ALK-NCK2 gene fusion with response to crizotinib treatment; the patient achieved a progression-free survival of 23 months.
