title: Predictive value of PSA velocity over early clinical and pathological parameters in patients with localized prostate cancer who undergo radical retropubic prostatectomy.
abstract: OBJECTIVE
  To analyze the behavior of the prostate specific antigen velocity (PSAV) in localized prostate adenocarcinoma.
  
  
  METHODS
  We conducted a retrospective study of 500 men who had localized prostate adenocarcinoma, who underwent radical retropubic prostatectomy between January 1986 and December 1999. The PSAV was calculated for each patient and subsequently, the values were correlated with 5 groups: age, initial PSA value, clinical stage, tumor volume and Gleason score.
  
  
  RESULTS
  The behavior of PSAV presented statistic significance with an increment between 1.3 ng/mL and 9.6 ng/mL, ranging from 38.6% and 59.8% when compared with the initial PSA value (p < 0.0001), clinical stage (p = 0.0002), tumor volume (p < 0.0001) and Gleason score (p = 0.0009).
  
  
  CONCLUSIONS
  PSAV up to 2.5 ng/mL/year is associated with factors of good prognosis, such as initial PSA below 10 mg/mL, clinical stage T1, tumor volume below 20% and Gleason score lower than 7.
