An Empirical Evaluation of Guidelines on Prostate-specific Antigen Velocity in Prostate... - 0 views
-
men with a high PSA velocity (rate of change of PSA level)—greater than 0.35 ng mL−1 y−1—should consider biopsy even if absolute level of PSA is very low.
-
like other authors, we found strong evidence for a univariate association between PSA velocity and positive biopsy
-
we also found that PSA velocity does not add important predictive value to PSA and other standard predictors; in other words, we did not find that the use of a PSA velocity criterion for biopsy would improve clinical decision making
