Abstract:

Objective

To explore the expression of CXCL5 in resectable human hepatocellular carcioma(HCC) and evaluate the role of CXCL5 in the pathogenesis, proliferation, invasion and metastasis of HCC.

Methods

Collect the tissue specimen of HCC patients after resection and their clinicopathological data. The expression of CXCL5 in tumor, adjacent-tumor tissues and corresponding normal liver tissue were detected by immunohistochemistry(IHC) Elvision method.

Results

The IHC detection of CXCL5 indicates that the rate of positive of staining of CXCL5 was significantly higher than that in adjacent-tumor tissue (P < 0.01) and corresponding normal tissue (P < 0.01). The expression of CXCL5 was positive correlated significantly with portal vein tumor invasion, BCLC staging and TNM staging, and negative correlation with pathological grades. Cox analysis identified the high expression of CXCL5 as one of the independent risk factors predictive of poor prognosis (HR 1.734, P = 0.001).

Conclusions

The expression and concentration of CXCL5 were higher in HCC. They associated with pathological grade, portal vein tumor thrombosis, progression of tumor and clinical stage. High expression of CXCL5 is one of the independent risk factors predictive of poor prognosis.
