MVD in relation to Gleason score and COX-2 expression in prostate cancer tissues

MVD*
Mean ± SDP
Gleason score
    ≤75.30 ± 1.52
    >78.02 ± 2.95<0.0001
COX-2 expression
    Negative5.50 ± 2.10
    Positive7.06 ± 2.710.001
  • * MVD means the counting of CD31-marked microvessels under the HPF × 400.

  • COX-2 expression: negative means COX-2 immunohistochemical score (HPF × 400) is less than 1. Positive means COX-2 immunohistochemical score is 1 or >1.
