MRI in Diagnosing Prostate Cancer
PROMIS - Prostate MRI Imaging Study - Evaluation of Multi-Parametric Magnetic Resonance Imaging in the Diagnosis and Characterization of Prostate Cancer
RATIONALE: Diagnostic procedures, such as magnetic resonance imaging (MRI), may help find prostate cancer and learn the extent of disease.
PURPOSE: This clinical trial is studying the safety of MRI and to see how well it works in diagnosing prostate cancer.

Gedetailleerde beschrijving
OBJECTIVES:
- To determine the ability of multiparametric magnetic resonance imaging (MP-MRI) to identify men who can safely avoid unnecessary biopsy.
- To assess the ability of the MP-MRI-based diagnostic pathway to improve the rate of detection of clinically significant cancer as compared to transrectal ultrasound (TRUS) biopsy.
- To estimate the cost-effectiveness of an MP-MRI based diagnostic pathway.
OUTLINE: This is a multicenter study.
Patients undergo multiparametric magnetic resonance imaging (MRI) (T2-weighted imaging, diffusion-weighted MRI, and dynamic contrast-enhanced MRI) followed by template prostate mapping and transrectal ultrasound biopsy.
Some patients may undergo blood, urine, and tissue sample collection periodically for biomarker studies. Samples are banked for future research analysis.
Patients complete a quality-of-life questionnaire (EQ-5D) at baseline, during, and after completion of study. An economic analysis will be performed for cost-effectiveness.
After completion of study intervention, patients are followed up periodically.

Beschrijving
DISEASE CHARACTERISTICS:
- Men at risk of prostate cancer who have been advised to have a prostate biopsy
- Suspected stage ≤ T2 on rectal examination (organ confined)
- Serum PSA ≤ 15 ng/mL within the past 3 months
PATIENT CHARACTERISTICS:
- Fit for general/spinal anesthesia
- Fit to undergo all protocol procedures including a transrectal ultrasound
- No evidence of a urinary tract infection or history of acute prostatitis within the past 3 months
- No contraindication to MRI (e.g., claustrophobia, pacemaker, or estimated GFR ≤ 50)
- No other medical condition precluding procedures described in the protocol
PRIOR CONCURRENT THERAPY:
- No prior prostate biopsy, prostate surgery, or treatment for prostate cancer (interventions for benign prostatic hyperplasia/bladder outflow obstruction are acceptable)
