TS expression led to the stratification of patients with colon cancer, but not rectal cancer, with immunophenotypes other than p21WAF1+/p53- (referred to as P&P) into subgroups characterized by a worse (P&P TS+) and a better (P&P TS-) DFS and OS, in univariate (P = 0.006 and P = 0.005, respectively) and multivariate (P = 0.0004 and P = 0.002, respectively) analyses. Here, TP53 is linked to malignant colon neoplasm.
