SELENBP1 and renal cell carcinoma: Univariate analysis using a Cox proportional hazards model to evaluate the potential utility of SELENBP1 mRNA expression as a prognostic marker in RCC after surgery showed that SELENBP1 expression (P = 0.019), Fuhrman grade (P = 0.010), N stage (P < 0.001), M stage (P < 0.001), and T stage (P < 0.001) were prime variables for cancer-related death (Table 4).
