Caveolin-1 is the major structural protein in caveolae, implicated in oncogenesis and angiogenesis. The connections between caveolin-1 and progression and angiogenesis of hepatocellular carcinoma (HCC) is still not clear. Thus we investigated the relationship of caveolin-1 expression, vascular endothelial growth factor (VEGF) expression, microvessel density (MVD), and unpaired artery (UA) with the clinicopathologic features of patients with HCC. Formalin-fixed, paraffin-embedded tissue sections of HCC from 75 patients who had undergone an initial hepatectomy were stained immunohistochemically with specific antibodies against caveolin-1, VEGF, CD34 and alpha-SMA. The levels of caveolin-1, VEGF, MVD and UA were correlated with the clinicopathologic variables, and tissue sections were also analyzed by dual-label immunofluorescence. We found that increased expression of caveolin-1 was associated with metastasis and with a worse prognosis of HCC. Caveolin-1 expression correlates positively with VEGF, MVD and UA. These results suggest that caveolin-1 may play an important role in the progression of HCC and angiogenesis.
