【 摘 要 】

Frizzled-related protein (FRZB) was up-regulated in hepatic metastasis samples compared with primary colon cancer samples in our previous work. However, the clinical relevance of FRZB in colon cancer hepatic metastasis remains uncertain. The aim of this study was to assess the prognostic value of FRZB in patients with colon carcinoma hepatic metastasis after hepatic resection. FRZB expression was evaluated by immunohistochemistry in formalin-fixed paraffin embedded (FFPE) primary colon carcinoma and paired hepatic metastasis tissues from 136 patients with liver metastasis from colon carcinoma that underwent hepatic resection. The relation between FRZB expression and clinicopathologic factors and long-term prognosis in these 136 patients was retrospectively examined. The prognostic significance of negative or positive FRZB exspression in colon carcinoma hepatic metastasis was assessed using Kaplan-Meier survival analysis and log-rank tests. Positive expression of FRZB was correlated with liver metastasis of colon cancer. Univariate analysis indicated significantly worse overall survival (OS) for patients with a positive FRZB expression in colon carcinoma hepatic metastasis than for patients with a negative FRZB expression. Multivariate analysis showed positive-FRZB in colon carcinoma hepatic metastasis to be an independent prognostic factor for OS after hepatic resection (P = 0.001). Positive expression of FRZB was statistically significantly associated with poor prognosis of patients with colon carcinoma hepatic metastasis. FRZB could be a novel predictor for poor prognosis of patients with colon carcinoma hepatic metastasis after hepatic resection.
