Abstract:
Objective:To explore the expression of FK506 binding protein 65 (FKBP65) in hepatocellular carcinoma (HCC) tissues and evaluate the prognosis value of FKBP65 in HCC. Methods:The expression of FKBP65 was detected by immunohistochemical staining in 147 HCC tissue samples. The correlation between FKBP65 and other clinical and pathological characteristics was analyzed. Univariate Kaplan-Meier analysis and multivariate Cox proportional hazard regression model analysis were performed to investigate the overall survival and recurrence free survival. Results:FKBP65 was expressed both in the tumor cells and stroma cells in the HCC tissues. The FKBP65 expression in stroma cells was positively associated with tumor sizes (P=0.001). The univariate analysis showed that the patients with high FKBP65 expression in stroma cells group had lower overall survival and recurrence free survival compared with low FKBP65 expression group (P=0.002, P=0.011). The Multivariate analysis showed that the high FKBP65 expression in stroma cells was an independent risk factor for the overall survival (HR=2.676, 95%CI 1.463-4.859) and recurrence free survival (HR=1.731, 95%CI 1.032-2.905). Conclusions:High FKBP65 expression in stroma cells of the HCC tissue might be associated with poor clinical outcomes.
