Clinical Trial Summary

1. Using multiparametric MRI Ultrasound-guided or MRI-guided biopsies will allow more accurate sampling of the tumors and therefore will increase the rate of "progression" on early (first and second) surveillance biopsies and decrease the rate of "progression" on late (third and further) surveillance biopsies compared to Transrectal Ultrasound-guided biopsies.

2. Quality of life (QoL) will be similar in patients undergoing MRI Ultrasound or MRI-guided and Transrectal Ultrasound-guided biopsies.

3. Biomarker expression levels will correlate with biopsy progression.


Clinical Trial Description

Favorable risk patients will be randomized to one of two active surveillance arms. Stratification will be based on Prostate-specific antigen density (PSAD) (=< 0.15 vs > 0.15 ng/mL per mL), and number of positive cores in the diagnostic biopsy (1 vs 2):

- Arm I: Active Surveillance Alone (AS). TRUS guided biopsies at start (within 6 months of enrollment) and at yearly intervals thereafter up to 36 months after the initial biopsy (maximum four biopsies).

- Arm II: MRI-Managed Active Surveillance (MRI-AS). MRIus or MRI-guided biopsies at start (within 6 months of enrollment) and at yearly intervals thereafter up to 36 months after the initial biopsy (maximum four biopsies).

Patients will also complete Quality of Life (QoL) assessments to provide unique data on the effects of MRI monitoring for patients undergoing active surveillance on QOL. The investigators have selected a group of measures that have been used extensively in prostate cancer populations. ;
