Purpose : Angiogenesis plays an important role in progression, invasion and
metastasis of solid tumors. The Vascular Endothelial Growth Factor (VEGF) is thought
to be a selective mitogen for endothelial cells. Hepatocellular carcinoma is a typical
hypervascular tumor. However, the relationship between angiogenesis and angiogenic
factor in hepatocellular carcinoma has not been evaluated. We investigated the
relationship between microvessel density (MVD) and expression of VEGF in
hepatocellular carcinoma.
Materials and Methods : Immunohistochemical staining, using anti-CD34 and
anti-VEGF antibodies, was applied in 32 cases of hepatocellular carcinoma. Also,
relationship between these neovascvlar factors (MVD and VEGF expression) and
clinicopathologic parameters such as tumor size, histologic grade, alpha-fetoprotein level,
hepatitis B virus surface antigen, presence of cirrhosis and survival was evaluated.
Results : CD34 was reactive throughout the neoplastic tissue, albeit it was confined to
a few periportal sinusoids and vessels in fibrous septa of adjacent cirrhotic liver MVD
was 59.6¡¾22.7 and 44.3¡¾21.5 in hepatocellular carcinoma and cirrhosis, respectively.
VEGF was expressed in 9 cases (28.1%) of hepatocellular carcinoma, which was
localized to the cytoplasm. MVD and VEGF expression was not significantly correlated
(P>0.05). MVD was correlated with presence of cirrhosis and inversely correlated with
alpha-fetoprotein level (P<0.05). MVD was not correlated with tumor size, presence of
HBs antigen, histologic grade and survival (P>0.05). Expression of VEGF was not
correlated with all clinicopathologic parameters (P>0.05).
Conclusion : These results indicate that MVD in hepatocellular carcinoma is not
directly correlated with VEGF expression, and suggest that other angiogenic factor may
be involved in neovascularization of hepatocellular carcinoma. However, CD34 expression
is closely associated with neovascular process in cirrhosis and hepatocelluar carcinoma.
