The NanoString-based multigene assay as a novel platform to screen EGFR, HER2, and MET in patients with advanced gastric cancer

摘要

Introduction Molecular targets are emerging rapidly and the development of clinical tests that simultaneously screen for multiple targets has become especially important. We assessed the gene expression levels of three known targets in advanced gastric cancer, epidermal growth factor receptor (EGFR), human epidermal growth factor 2 (HER2), and N-methyl-N-nitrosoguanidine human osteosarcoma transforming gene (MET), using the nCounter® assay (NanoString Technologies, Seattle, WA, USA) and compared these results with protein overexpression, detected by immunohistochemistry, to evaluate the performance of this new technology.
