  1. Prostate-specific antigen velocity and repeated measures of prostate-specific antigen : Prostate-specific antigen : the best prostatic tumor marker.

    Fascicule - En anglais

    Prostate-specific antigen velocity (PSAV), or rate of change in PSA, is a concept that considers the changes in PSA between measurements adjusted for the elapsed time between the measurements.

    Because there is substantial individual variability between PSA measurements, a simple change in PSA is not useful as a marker for prostate cancer ; however, studies suggest that if PSAV is evaluated during at least 1.5 to 2 years, (1) less than 5% of men without prostate cancer have a PSAV of 0.75 ng/mL per year or more and (2) more than 70% of men with prostate cancer have a PSAV of 0.75 ng/mL per year or more.

    These data suggest that PSAV is a specific marker for prostate cancer that can be used as one method for assessing the risk that prostate cancer is present.
