Abstract: OBJECTIVE:To investigate expression of secreted frizzled-related protein 4 (sFRP4) in hepatocellular carcinoma (HCC) and relationship with clinicopathological index and prognosis. METHODS:Immunohistochemical methods were used to detect the expression of sFRP4 protein in 95 surgically resected HCC tissues and paracancerous tissues; patients clinicopathological indexes were used to analyze relationships with expression levels of the sFRP4 protein; the Kaplan-Meier survival curves were used to analyze relationships between expression of the sFRP4 protein and prognosis of the patients based on their clinicopathological index; and proportional hazards model (COX) was used to analyze factors affecting the prognosis of HCC patients. RESULTS:The positivity rate of sFRP4 protein was 48.42% (46/95) in HCC tissues and 85.26% (81/95) in paracancerous tissues. sFRP4 protein was therefore less positive in HCC tissues than in paracancerous tissues (χ2=24.596,P<0.01). Its expression in HCC tissues were significant for different histological grade (χ2=11.877,P<0.05),histological subtype (χ2=3.873,P<0.05) and microvascular invasion (χ2=6.493,P<0.05). Patients with the sFRP4 protein-negativity had significantly worse cumulative overall survival (OS) and cumulative disease-free survival (PFS) than that of the positive group (both P<0.01). Cox multivariate analysis showed that sFRP4 protein [HR=0.238,95%CI(0.138,0.412),P<0.01],clinical stage of hepatocellular carcinoma in China [HR=2.438,95%CI(1.256,4.730),P<0.01] were independent risk factors affecting the PFS after surgical resection of HCC. In addition,the sFRP4 protein [HR=0.226,95%CI(0.109,0.467),P<0.01] and histological grade [HR=2.236,95%CI(1.199,4.170),P<0.05] were independent risk factors affecting the OS after surgical resection of HCC. CONCLUSION:Expression levels of the sFRP4 protein were differentially significant between the HCC and paracancerous tissues,as well as with histological grade,histological subtype and microvascular invasion in HCC tissues. The sFRP4 protein-negative group of patients had a poorer prognosis. In addition,its expression level was an independent risk factor for the prognosis of these patients after surgical resection.
