About

The commercialization of MRI fusion biopsies has resulted in a dramatic increase in the use of MRI imaging for prostate cancer. How best to use MRI in the initial prostate biopsy setting given the availability of validated prostate cancer early detection markers is uncertain.This study will allow investigators to determine if prostate MRI is superior to validated panel of laboratory biomarkers (e.g. PCA3, PSA and TMPRSS2:ERG) in the initial biopsy setting.

Full description

The primary aim of this study is to see if the addition of prostate MRI to a panel consisting of PSA, PCA3, TMPRSS2:ERG will significantly improve specificity for high-grade prostate cancer by 10%. The subsequent exploratory aims will 1) create an optimal panel of urine, blood and tissue biomarkers that will select those cases most likely to benefit from a MRI targeted biopsy, 2) directly compare PSA and urinary biomarkers with MRI to determine which ones are value added in the setting of initial biopsy, 3) evaluate changes in these biomarkers and MRI to determine if longitudinal changes predict subsequent high-grade prostate cancer, and 4) optimize MRI imaging to improve test performance. Importantly, this study will create a unique, prospective, cohort that will become the foundational reference set for of a range of future biomarker studies.

Inclusion criteria

• Men with suspected but undiagnosed prostate cancer

Exclusion criteria

• Inability to obtain blood and urine per SOP or conduct an attentive DRE
• Unable to undergo/tolerate a prostate MRI or failure to conduct the MRI
• Prior diagnosis of prostate cancer

Trial design

950 participants in 1 patient group

Initial prostate biopsy

Description:

Men who have never had a prostate biopsy, but have an elevated risk for prostate cancer such as elevated PSA who are scheduled or considered candidate for an initial prostate biopsy.

Treatment:

Diagnostic Test: MRI prostate
