摘要

MET protein (also known as c-Met protein) overexpression (OE) is an emerging clinically relevant biomarker that is targetable with antibody-drug conjugates. c-Met protein’s prevalence varies, depending on the different OE thresholds, antibodies, and detection methodologies used. Unlike MET genomic aberrations, MET protein OE is a protein biomarker requiring immunohistochemistry (IHC)-based testing. Herein, we summarize the current evidence on MET protein OE, including prognostic value, heterogeneity, and stability. We also provide key considerations for enabling optimal real-world testing of this IHC-based biomarker.
