摘要
Aim: Plasma fibrinogen and D-dimer have been reported to predict survival in several types of malignancies. The aim of this study is to investigate their predictive value in patients with hepatocellular carcinoma (HCC). @@@ Methods: We retrospectively analyzed plasma fibrinogen and D-dimer levels from 252 subjects: control (n=20), hepatitis (n=20), cirrhosis (n=20), and HCC (n=192) subjects. The clinical involvement and prognostic value of fibrinogen and D-dimer was analyzed in HCC subjects. To confirm the effects of tumor on hypercoagulability and fibrinolysis, fibrinogen and D-dimer levels were measured in nude mice following HCC inoculation. @@@ Results: Fibrinogen decreased and D-dimer increased in cirrhosis subjects relative to other groups. In HCC subjects, elevated fibrinogen and D-dimer levels were significantly associated with adverse tumor features (increased size, stage, and grade) and systemic inflammation. Patients with HCC with either elevated fibrinogen or D-dimer levels had significantly higher 3-year tumor recurrence rates (65% vs. 41%, P<0.001 for fibrinogen; 67% vs. 40%, P=0.011 for D-dimer) and significantly lower 3-year overall survival rates (57% vs. 79%, P<0.001 for fibrinogen; 56% vs. 80%, P=0.001 for D-dimer). After multivariate analysis, elevated fibrinogen levels remained an independent predictor of poor prognosis in HCC patients. Finally, elevated levels of fibrinogen and D-dimer were confirmed in nude mice following tumor inoculation. @@@ Conclusion: The fibrinogen and D-dimer levels, elevating after carcinogenesis, may serve as simple but effective predictors of adverse tumor profiles and outcomes in HCC.
