title: [Significance of proliferating cell nuclear antigen (PCNA) index and microvessel density (MVD) in endometrial carcinoma].
abstract: OBJECTIVE
  Incidence of endometrial carcinoma (EC) is ascending, but its pathogenesis and prognosis are unclear. This study was designed to investigate correlation of proliferating cell nuclear antigen (PCNA) index, and microvessel density (MVD) to pathologic stage, and differentiation of endometrial carcinoma.
  
  
  METHODS
  PCNA index and MVD in 62 specimens of endometrial carcinoma, and 22 specimens of normal endometrium were detected by SP immunohistochemistry. Correlation of PCNA index, and MVD to pathologic stage, and differentiation of endometrial carcinoma was statistically analyzed.
  
  
  RESULTS
  PCNA index, and MVD in endometrial carcinoma were significantly higher than those in normal endometrium (54.5+/-9.3 vs. 32.7+/-7.7, and 49.0+/-8.6 vs. 32.4+/-11.0,P<0.05). PCNA index and MVD positively correlated with pathologic stage and differentiation of endometrial carcinoma (P<0.05). PCNA index positively correlated with MVD in endometrial carcinoma.
  
  
  CONCLUSIONS
  The increase of PCNA index and MVD may enhance development of endometrial carcinoma. Angiogenesis might play a role in promoting cell proliferation.
