Negative Ultraselection of Patients With RAS/BRAF Wild-Type, Microsatellite-Stable Metastatic Colorectal Cancer Receiving Anti–EGFR-Based Therapy
11 May 2022
Abstract excerpt
PURPOSE Several uncommon genomic alterations beyond RAS and BRAFV600E mutations drive primary resistance to anti–epidermal growth factor receptor (EGFR) monoclonal antibodies in metastatic colorectal cancer (mCRC). Our PRESSING panel (including PIK3CA exon 20/ AKT1/ PTEN mutations, ERBB2/ MET amplifications, gene fusions, and microsatellite instability-high status) represented a paradigm of negative...
