Performance of Prostate Cancer Prevention Trial Risk Calculator in a Contemporary Cohort Screened for Prostate Cancer and Diagnosed by Extended Prostate Biopsy

To our knowledge our external validation of the Prostate Cancer Prevention Trial risk calculator was done in the largest cohort of men screened for prostate cancer to date. Results suggest that the current calculator remains predictive but does not maintain initial accuracy in contemporary patients sampled by more extensive biopsy schemes. Data suggest that the predictive ability of the calculator in current clinical practice may be improved by modeling contemporary data and/or incorporating additional prognostic variables.
