Abstract

The purpose of this study was to determine if early PSA velocity (EPSAV), drawn from PSA values within normal ranges, predicts the later occurrence of abnormally high PSA values or positive prostate biopsy early enough to be clinically beneficial. Early PSAV (ng/ml/y) calculated from two normal PSA readings was tested to predict later PSA exceeding 4 ng/ml (1551 evaluable patients) or 10 ng/ml (1905 evaluable patients) and positive prostate biopsy. The time from EPSAV to develop abnormal PSA was recorded. A post-EPSAV PSA > 4 ng/ml was reached by 367 patients and > 10 by 293. EPSAV was significantly different (P <0.001) between patients whose PSA did or did not reach the PSA cut-off point and also significantly predicted a positive biopsy result (P <0.001). EPSAV predicted abnormal PSA more than 1 y in advance in 68 and 52% of the PSA 4 and 10 ng/ml cut-off point groups, respectively. Early PSAV from normal PSA readings may allow early detection of men at risk for prostate cancer. This may help identify men for earlier prostate biopsy or for less frequent PSA monitoring.
