In contrast multivariate analysis models including the GS and pT stage showed that neither high SSEA-4 cancer cell expression or the presence of SSEA-4-positive TICs was as independent predictors of BCR-free survival (HR = 1.90, P = 0.095 and HR = 1.76, P = 0.138, respectively; Table 3). This evidence concerns the gene BCR and cancer.
