ABSTRACT
AIM:
To investigate the angiogenesis status,the expression of vascular endothelial growth factor(VEGF),angiopoietin-1(ANG-1),angiopoietin-2(ANG-2),thrombospondin-1(TSP-1) in cholangiocellular carcinoma(CCC) and relationship with tumor angiogenesis,differentiation,invasion and metastasis.METHODS:
33 specimen of surgically resected CCC were investigated.Immunohistochemical staining of CD34,VEGF,ANG-1,ANG-2 and TSP-1 was carried out.RESULTS:
The mean MVD was(87.2?52.6)/mm2.VEGF positive expression was found in 75.6% cases;ANG-1 positive expression was observed in 36% cases;ANG-2 positive was detected in 57.6% cases and 45.5% cases exhibited positive TSP-1 expression.VEGF and ANG-2 expressions were found to be associated with significant higher level of MVD(P
