The Asian Cancer Research Group (ACRG) in 2015 also proposed a new molecular typing of gastric cancer as microsatellite stable/epithelial-mesenchymal transformation (MSS/EMT) type, microsatellite unstable (MSI) type, microsatellite stable/tumor protein 53 active (MSS/TP53+) type and microsatellite stable/tumor protein 53 inactive (MSS/TP53-) type 10. This evidence concerns the gene TP53 and cancer.
