However, the clinical significance of SFRP1 expression in patients with hepatocellular carcinoma (HCC) remains unknown. Materials and Methods: A total of 63 patients with HCC who underwent hepatectomy at our Institution were enrolled in this study. A quantitative real-time polymerase chain reaction (RT-PCR) was performed to determine the SFRP1 mRNA expression level in both the tumorous and non-tumorous tissues of HCC. The patients were divided into low and high gene-expression groups based on the SFRP1 gene expression level in their tumor tissues. We analyzed the differences in clinicopathological characteristics between these two groups of patients. Result: The expression level of SFRP1 was significantly lower in tumor tissue than in non-tumor tissue (p<0.0001). Significant correlations were observed between a high expression of SFRP1 in tumor tissue and older than 65 years (p=0.030), tumor size less than 5 cm (p=0.011); and no vascular invasion (p=0.004). Patients with high SFRP1 expression in tumor tissue had a significantly better overall survival rate (p=0.040). However, the SFRP1 expression level was not defined as an independent risk factor for patient survival based on results of multivariate analysis. Conclusion: SFRP1 may play a role in the development and progression of HCC. Therefore, more studies are required to investigate a potential role of SFRP1 in HCC prognosis.
