  • Expression and Significance of VEGF-C in Hepatocellular Carcinoma

    Objective To investigate the expressions of vascular endothelial growth factor-C (VEGF-C) and its receptor Flt-4 in hepatocellular carcinoma (HCC), in order to analyze the relationships among their expressions, angiogenesis, lymph-genesis, and clinicopathologic features of HCC. Methods Sixty-two cases of HCC and 15 cases of normal hepatic tissue were studied with immunohistochemical method in order to inspect the expressions of VEGF-C and Flt-4, and to calculate the microvessel density (MVD) marked by CD34 and the lymphatic vessel density (LVD) marked by Flt-4. Besides their correlations, their relations with clinicopathologic features of HCC were further analyzed. Results The positive rates of VEGF-C and Flt-4 were obviously higher in HCC than those in normal hepatic tissue (Plt;0.05, Plt;0.01). The expression of VEGF-C in HCC was remarkably related with portal vein tumor emboli, histological differentiation of HCC, and postoperative recurrence and metastasis (Plt;0.05, Plt;0.01). The expression of Flt-4 in HCC was also related with histological differentiation and postoperative recurrence (Plt;0.05, Plt;0.01). MVD was related with tumor size, TNM clinical stage, histological differentiation, portal vein tumor emboli, and postoperative recurrence and metastasis (Plt;0.05, Plt;0.01). LVD was related with histological differentiation, postoperative recurrence and metastasis (Plt;0.05, Plt;0.01). Additionally, there was positive correlation between VEGF-C and Flt-4, MVD or LVD, Flt-4 and MVD or LVD, MVD and LVD, respectively (Plt;0.01). Conclusions VEGF-C and Flt-4 are highly expressed in HCC, and are related with postoperative recurrence, are positive correlated with MVD and LVD. It suggests that VEGF-C/Flt-4 might has an effect on progression and prognosis of HCC through promoting angiogenesis and lymph-genesis.

  • Advances of Study on Angiogenesis and Antiangiogenic Therapy in Hepatocellular Carcinoma

    Objective To introduce the possible effects and significances of angiogenesis and antiangiogenic in the development and treatment of hepatocellular carcinoma (HCC). Methods Recently relevant literatures were reviewed. Results Angiogenesis played a significant role in the development and therapy of HCC, and the development and metastasis of HCC could be effectively suppressed by antiangiogenic therapy. This might provide a new approach for the treatment of HCC. Conclusion Comprehending the molecular mechanism of angiogenesis and applying antiangiogenic therapy will contribute a lot for the prevention and treatment of HCC.
