Potential Unreliability of Uncommon ALK, ROS1, and RET Genomic Breakpoints in Predicting the Efficacy of Targeted Therapy in NSCLC

Introduction: Variable genomic breakpoints have been identified through the application of target-capture DNA next-generation sequencing (NGS) for ALK, ROS1, and RET fusion detection in NSCLC. We investigated whether ALK, ROS1, and RET genomic breakpoint location can predict matched targeted therapy efficacy. Conclusions: Uncommon ALK, ROS1, and RET genomic breakpoint is an unreliable predictor of matched targeted therapy efficacy. Functional validation by RNA or protein assay may add value for the accurate detection and interpretation of rare fusions. READ ARTICLE
