Brief Summary
This high resolution MRI (hrMRI), along with stand MRI (sMRI) will be obtained at baseline and again in approximately 1 year in patients on prostate cancer active surveillance. Changes in lesion size and ADC values will be assessed on the serial studies. This study evaluates the hypothesis that hrMRI will detect changes that sMRI cannot detect and that these changes will correlate with prostate cancer progression as determined on prostate biopsy.

Outcome Measures
Primary Outcomes (2)
Sensitivity and Specificity of High Resolution Versus Standard MRI in Identifying Adverse Histology
The primary endpoint of the clinical trial was the presence of adverse histology (AH) on prostate biopsy. We defined adverse histology (AH) as either overall Gleason score of 7 or more on any biopsy, or an increase of 3 or more positive cores on serial systematic biopsies. The primary hypothesis was that change in tumor size or apparent diffusion coefficient (ADC) as detected by high resolution MRI (hrMRI) would better predict AH than standard MRI (sMRI). AH histology was a measure intended to capture patients with high Gleason grade component (i.e. Gleason Grade 4 or 5) and patients progressing (e.g. from Gleason Group 1 to Gleason Group 2 or from Gleason Group 2 to Gleason Group 3). The sample size was too small and the followup duration of approximately 12 months was too short to assess only true cancer progression as the endpoint. The presence of AH alone is clinically important since these patients may need close followup and may consider definitive local therapy.

Limitations and Caveats
The number of patients in our study was relatively small. The reference standard was prostate biopsies, which is subject to sampling error. However, this was necessary when investigating a low-risk, small-volume cancer that is managed nonoperatively. Our study was performed at a single center and the imaging protocol was developed by our team.
