Recently, Cristescu et al., 2015 [58] investigated a gene expression dataset of 300 primary gastric tumors to sectionalize four molecular subtypes of GC, which were connected with different patterns of molecular alteration, prognosis of GC patients, progression, and cancer prognosis, which encompass MSS/TP53+ subtype, MSS/TP53− subtype, MSI subtype, and MSS/EMT subtype. The gene discussed is TP53; the disease is gastric cancer.
