title: [Correlation between expression of matrix metalloproteinase-2 and angiogenesis in esophageal carcinoma].
abstract: OBJECTIVE
  To study expression of MMP-2 in relation to microvessel density (MVD) in esophageal carcinoma.
  
  
  METHODS
  Forty-eight specimens of esophageal carcinoma (Ec) and 17 specimens of grade II + III epithelial dysplasia (Dy) close to the tumor and 12 specimens of normal tissue (Nt) along the incisional margin were examined by S-P immunohistochemical staining with anti-MMP-2 monoclonal antibody. An anti-CD34 monoclonal antibody was used to show MVD.
  
  
  RESULTS
  MMP-2 expression in Ec was remarkably higher than that in Dy, which was higher than that in Nt. MMP-2 expression in Ec and Dy was significantly correlated with MVD in the tumor and nearby tissue. MMP-2 expression and MVD in Ec significantly associated with lymph node metastasis.
  
  
  CONCLUSIONS
  Expression of MMP-2 plays an important role in angiogenesis and lymph node metastasis of esophageal cancer.
