Anaplastic lymphoma kinase ( ALK ) gene rearrangement is an essential driver mutation identified in approximately 5% of non-small cell lung cancers (NSCLCs). The results of clinical trials have demonstrated the impressive efficacy of ALK tyrosine kinase inhibitors (ALK-TKIs). Besides the classic EML4-ALK fusions, a growing list of gene fusion partners for ALK in NSCLC have been identified with heterogeneous clinical responses to ALK-TKIs. However, a LOC101927967-ALK fusion has not been reported in NSCLC. Herein, a novel LOC101927967 downstream intergenic region ALK fusion in an early-stage patient with lung adenocarcinoma was first identified by next-generation sequencing (NGS) and verified by immunohistochemical staining (IHC) and fluorescence in situ hybridization (FISH), which might provide a treatment option for postoperative recurrence.
