Brief Summary
The main purpose of this study is to determine if Magnetic Resonance Imaging (MRI), along with MRI targeted biopsy of suspicious lesions, is of value in detecting patients who would be likely to require treatment earlier.

Outcome Measures
Primary Outcomes (1)
Rate of Disease Progression Within the First Two Surveillance Biopsies
The rate of disease progression among participants within the first two surveillance biopsies will be reported. Progression refers to a repeat surveillance biopsy indicating any one of the following: 1. More than 4 positive cores involving any grade of cancer, 2. At least two core with Gleason 3+4 cancer, 3. Any single core with Gleason 4+3 cancer or higher, 4. A Gleason 3+3 at diagnosis that is upgraded to Gleason 3+4, or 5. Undergoing treatment, regardless of histological progression.
24 months
Secondary Outcomes (4)
Time-to-Biochemical Recurrence (BCR)
Up to 36 months
Health-Related Quality of Life Scores: EPIC SF-12
Up to 36 months
Health-Related Quality of Life Scores: MAX-PC
Up to 36 months
Discriminative Performance of NCCN Risk and Clinical Markers for Predicting Progression on Active Surveillance
Up to 36 months
Study Arms (1)
Active Surveillance
EXPERIMENTALParticipants in this group will receive a Multi-Parametric Magnetic Resonance Imaging (MP-MRI) of the prostate/pelvis and MRI-guided prostate biopsy at baseline (0-3 months from enrollment) and at the 12th, 24th and 36th month follow up.

Eligibility Criteria
You may qualify if:
- Biopsy confirmed adenocarcinoma of the prostate within 18 months prior to enrollment;
- Pre-enrollment prostate biopsy must consist of at least 8 cores;
- Biopsy reviewed by a University of Miami Pathologist;
- Serum Prostate-Specific Antigen (PSA) ≤ 20 ng/ml within 3 months of study enrollment;
- Age ≥ 35 and ≤ 85 years;
- Ability to understand and willingness to sign a written informed consent document;
- Patients must agree to undergo serial multiparametric MRI and MRI-guided biopsy;
- Patients must agree to fill out the longitudinal psychosocial questionnaires assessing health related quality of life.
You may not qualify if:
- Greater than 4 cores positive, of any Gleason score, on the University of Miami (UM) review,
- Greater than 2 cores positive for Gleason 3+4 cancer,
- Gleason 4+3 or higher cancer in any single biopsy core.
- Subject is not a candidate for multiparametric MRI with contrast. Some reasons may include (but are not limited to): renal insufficiency, foreign body or pacemakers.
- No prior pelvic radiotherapy.
- No prior surgery to the prostate, other than transurethral procedures for benign prostatic hyperplasia (e.g., transurethral resection, green light laser treatment).
- No concurrent, active malignancy, other than non-metastatic skin cancer of any type, superficial bladder cancer, or early stage chronic lymphocytic leukemia (well-differentiated small cell lymphocytic lymphoma) or \<stage IV follicular lymphoma. If a prior malignancy is in remission for ≥ 3 years then the patient is eligible.
- Bilateral hip replacement.
