ABSTRACT

OBJECTIVES: To analyze the behavior of the prostate specific antigen velocity (PSAV) in localized prostate adenocarcinoma. MATERIALS AND 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 percent and 59.8 percent 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). CONCLUSION: 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 percent and Gleason score lower than 7.
