title: E-cadherin expression in prostate adenocarcinomas in Chinese and its pathological correlates.
abstract: BACKGROUND
  We examined the E-cadherin expression in prostate adenocarcinomas in Chinese to correlate this immunohistochemical marker with histopathological features.
  
  
  METHODS
  Primary adenocarcinomas from 122 radical prostatectomy specimens were stained using anti-E-cadherin (HECD-1) antibody. The association of E-cadherin expression with serum prostate-specific antigen (PSA), pathological stage and Gleason score was assessed by Kendall's tau-b test.
  
  
  RESULTS
  Aberrant E-cadherin expression was identified in 79 tumors (64.8%). Abnormal E-cadherin expression did not correlate to serum PSA (p = 0.802), tumor stage (p = 0.684) and Gleason score (p = 0.385).
  
  
  CONCLUSIONS
  The frequency of aberrant E-cadherin expression was higher in prostate adenocarcinomas of Chinese as compared to that reported in Caucasians. No association with pathological stage, Gleason score and serum PSA was identified.
