Medical Economics of Urinary PCA3 Test for Prostate Cancer Diagnosis

urinary PCA3 test will be performed in patients before they undergo prostate biopsy for increased serum PSA and/or abnormal digital rectal examination. Patients with negative biopsies will be definitively enrolled in the study. The physician in charge will have knowledge of PCA3 test results and will be asked to determine the subsequent follow-up taking these results into account.
