Objective To investigate the expression of HSPA9 in hepatocellular carcinoma(HCC)and its relationship with clinicopathological features and prognosis.Methods Forty-nine cases HCC treated by operative resection and follow up data in our hospital from January 2006 to January 2010 were retrospectively analyzed.Immunohistochemistry was performed to determine the expression of HSPA9 in HCC and paratumor tissues.The relationship between HSPA9 expression and clinicopathological features and prognosis was statistically analyzed.Results The HSPA9 protein expression in tumor tissue was higher that that in the paratumor tissue(t=6.601,P0.01),moreover the over expression of HSPA9 was significantly correlated with lymph node metastasis(P=0.005),TNM-stage(P=0.015),tumor differentiation(P=0.033),microvascular invasion(P=0.009)and recurrence(P=0.047).In the survival analysis results,the patients with over expression of HSPA9 had a much lower total survival rate(P=0.002)and much higher postoperative cumulative recurrence rate(P=0.003).There were significant differences in TNM-stage,microvascular invasion,lymph node metastasis,tumor differentiation and HSPA9 staining for overall survival and cumulative recurrence rate based on a univariate analysis(P0.05).Conclusion HSPA9 has over expression in HCC.The over expression of HSPA9 is closely related to invasion and metastasis pathological features and can serve as an independent prognostic risk factor for predicting the prognosis of HCC.
