    Author: Yang M, Chen G, Dang Y, Luo D.
    Journal: Ups J Med Sci; 2010 Nov; 115(4):232-7. PubMed ID: 20977315.
    Abstract:
    OBJECTIVE: Decoy receptor 3 (DcR3), a member of the tumor necrosis factor receptor superfamily, is amplified and over-expressed in various cancers. The objective of the present study was to investigate the concentration of DcR3 in sera of hepatocellular carcinoma (HCC) patients and its clinical significance. METHODS: Serum concentrations of DcR3 were measured by enzyme-linked immunosorbent assay (ELISA) in 67 patients with HCC, 8 with liver cirrhosis, 17 with cholecystitis, and in 28 healthy individuals. Immunohistochemistry was employed to access protein expression of DcR3 in the corresponding HCC tissues. RESULTS: Serum concentrations of DcR3 in patients with HCC or cirrhosis were significantly higher than in healthy individuals (P < 0.01). Moreover, serum concentrations of DcR3 in HCC patients were associated with TNM stage, para-cirrhosis, capsular infiltration, and metastasis or recurrence of disease (P < 0.05). There was a positive correlation between the serum concentration of DcR3 and protein expression in HCC tissues (r = 0.472, P < 0.01). CONCLUSIONS: The high serum concentration of DcR3 might play a certain role in pathogenesis, progress, and metastasis of HCC. Moreover, DcR3 might serve as a valuable molecular indicator in early diagnosis and contribute to predicting the clinical outcome in HCC patients.
