Core Tip
Core Tip: This study aimed to investigate pathological significance of mesenchymal-epithelial transition factor (MET) amplification in therapy-naïve colorectal cancer (CRC) and to propose a feasible screening strategy in clinical practice. In CRC harboring no RAS/RAF mutation or microsatellite instability, focal MET amplification was a rare event, while polysomy-caused MET amplification was observed in 14.4% of patients. Polysomy-caused MET amplification significantly correlated with frequent lymph node metastasis and higher tumor budding grade, which were two independent predictors of unfavorable CRC survival. Consistently, we discovered that MET amplification predicted poor outcome in a two-year follow-up. To our knowledge, this study firstly proved that c-MET immunohistochemistry (IHC) was not a suitable screening tool for MET amplification in CRC, and we recommend that tissue should be prioritized for fluorescence in situ hybridization over IHC to determine MET amplification.
