Brief Summary
Approximately one million transrectal prostate biopsies are performed annually in the U.S., and the risk of post- biopsy infection is increasing due to greater antibiotic resistance of rectal flora. Preliminary data demonstrates that a transperineal MRI-targeted biopsy approach under local anesthesia compared to the standard practice transrectal MRI-targeted prostate biopsy has a much lower risk of infection, comparable pain/discomfort and may improve detection of prostate cancer. This randomized controlled trial will be the first prospective study to evaluate in-office transperineal MRI targeted prostate biopsy. The investigators hypothesize that a transperineal MRI-targeted biopsy approach under local anesthesia compared to the standard practice transrectal MRI-targeted prostate biopsy has a much lower risk of infection, comparable pain/discomfort and may improve detection of prostate cancer.

Outcome Measures
Primary Outcomes (1)
Change in infection adverse events, as measured on TRUS-BxQ
TRUS-BxQ is a validated biopsy questionnaire that measures adverse events that have occurred due to infection. Patient questionnaire consists of Yes/No questions about infection complications and duration of infection.
At initiation of biopsy, immediately following biopsy, 7 days post-biopsy
Secondary Outcomes (4)
Change in patient-reported pain and discomfort, as measured on a 0-10 Likert scale
Immediately following biopsy, 7 days post-biopsy
Change in patient-reported anxiety, as measured on a 0-10 Likert scale
Immediately following biopsy, 7 days post-biopsy
Detection of clinically significant disease as measured by Gleason Grade Group ≥ 2
7 days post-biopsy
Change in adverse events, as measured on TRUS-BxQ
At initiation of biopsy, immediately following biopsy, 7 days post-biopsy
Study Arms (2)
Transrectal
ACTIVE COMPARATORPatients will receive a transrectal MRI-guided prostate biopsy.
Transperineal
ACTIVE COMPARATORPatients will receive a transperineal MRI-guided prostate biopsy.
Interventions
Transperineal prostate biopsy will be performed under local anesthesia in the office. This approach avoids transrectal needle tracking.
Transrectal prostate biopsy is currently the most popular approach to evaluate a positive screening test for prostate cancer.
For men undergoing transrectal biopsy, antibiotic prophylaxis will be administered in accordance with guidelines from the American Urological Association (AUA). No antibiotic prophylaxis will be administered for men undergoing transperineal biopsy.
Eligibility Criteria
You may qualify if:
- Active surveillance cohort: History of Grade Group 1 prostate cancer, first diagnosed ≤24 months prior to date of planned confirmatory biopsy and diagnostic biopsy was preceded by a multiparametric MRI of the prostate
- Prior negative cohort: Clinical concern for the presence of prostate cancer as determined by the treating urologist and prior negative prostate biopsy performed ≤36 months prior to date of planned biopsy
- Willingness to sign informed consent and adhere to the study protocol
You may not qualify if:
- Acute prostatitis within the last 6 months
- Current non-urologic bacterial infection requiring active treatment with antibiotics
- Unfit to undergo prostate biopsy under local anesthesia
- Prior definitive therapy for prostate cancer, such as radiation therapy or partial gland ablation
- Contraindication to prostate MRI (claustrophobia, pacemaker, chronic kidney disease)
