Prospective Validation of Prostate Biomarkers for Repeat Biopsy

ConfirmMDx is a molecular diagnostic assay which utilizes DNA isolated from biopsy tissues to determine if aberrant DNA methylation is occurring in three genes: GSTP1, RASSF1 and APC. ConfirmMDx is currently available to clinicians for use in cancer-negative extended-core biopsies to determine if occult cancer is present in the prostate.

SelectMDx for Prostate Cancer is a reverse-transcription PCR (RT-PCR) assay performed on post-DRE, first-void urine specimens from patients with clinical risk factors for prostate cancer, who are being considered for biopsy. The test measures the mRNA levels of the DLX1 and HOXC6 biomarkers, using KLK3 as internal reference gene, to aid in patient selection for prostate biopsy.
