The study suggested dividing gastric cancer into four subtypes: MSI-high (23%), microsatellite stable/epithelial-mesenchymal transition (MSS/EMT) (15%), microsatellite stable/epithelial/TP53 intact (MSS/TP53+, p53 active) (26%), and microsatellite stable/epithelial/TP53 loss (MSS/TP53-, p53 inactive) (36%). Here, TP53 is linked to gastric cancer.
