  • This abstract was presented as a poster at the World Congress of Controversies in Urology (CURy) meeting, 31 January -3 February 2008, Barcelona, Spain.
  • The study aimed to determine the diagnostic utility of the PCA3 Assay in 65 men with 1 or 2 negative prostate biopsies who were scheduled for repeat biopsy at the Medical University of Vienna and was part of a prospective, multi-national, multi-centre, European study1.
  • It showed that in men with a serum PSA of 2.5-10 ng/mL, at a PCA3 Score cut-off of 35, the specificity is 74%, the negative predictive value 82% and 33% of repeat biopsies could be avoided.
  • Follow-up of men with a PCA3 Score > 35 and a negative repeat biopsy showed that 60% of these men has high-grade prostate intraepithelial neoplasia (HGPIN; Table).
  • Preliminary data show that the majority of these men has a positive biopsy at further follow-up.
