MRI-Based Active Surveillance to Avoid the Risks of Serial Biopsies in Men With Low-Risk Prostate Ca
- Conditions
- Prostate CancerMultiparametric MRIProstate AdenocarcinomaGleason's Score 6
- Interventions
- Procedure: TRUS-guided biopsyProcedure: mpMRI with targeted biopsy
- Registration Number
- NCT02564549
- Lead Sponsor
- Virginia Commonwealth University
- Brief Summary
Phase II non-inferiority randomized trial of annual systematic biopsies versus mpMRI and targeted biopsies for men with low risk prostate cancer on active surveillance with any volume Gleason's Score 6, but no prior MRI imaging of the prostate.
- Detailed Description
This is an unblinded, randomized trial of TRUS biopsy-based active surveillance versus mpMRI-based active surveillance. Patients on the TRUS biopsy-based arm will undergo annual systematic biopsies without any MRI staging or guidance. Patients on the mpMRI- based arm will undergo annual mpMRI surveillance imaging, with image-guided targeted biopsies only as indicated by radiographic findings.

Group Intervention Description Group 1 (TRUS-guided biopsy) TRUS-guided biopsy * Baseline and annual systematic TRUS-guided biopsy performed as per standard of care by urologists for a total of one baseline diagnostic biopsy and two active surveillance systematic biopsies. * mpMRI at the end of the 2nd year with targeted biopsy of any Prostate Imaging Reporting and Data System (PI-RADS) 4 or 5 lesion. Patients needing image- guided targeted biopsies will undergo this procedure by interventional radiology, which is a common standard of care at HHM VAMC. * Optional transperineal template biopsy of the prostate performed at end of 2nd year (month 25-30). * Patients will be followed, as per standard of care, for any potential infections from biopsies. * Annual PSA tests performed as per routine standard of care. Group 2 (mpMRI with targeted biopsy) mpMRI with targeted biopsy * Baseline systematic transrectal ultrasound-guided biopsy performed as per standard of care by urologists. * Baseline and annual mpMRI with targeted biopsy of any Prostate Imaging Reporting and Data System (PI-RADS) 4 or 5 lesion. Patients needing image- guided targeted biopsies will undergo this procedure by interventional radiology, which is a common standard of care at HHM VAMC. * Optional transperineal template biopsy of the prostate performed at end of 2nd year (month 25-30). * Patients will be followed, as per standard of care, for any potential infections from biopsies. * Annual PSA tests performed as per routine standard of care.
- Primary Outcome Measures
Name Time Method To asses the detection rate of Gleason score ≥ 4+3 in patients with low-risk prostate cancer who undergo transrectal ultrasound (TRUS) biopsy-based active surveillance (Group 1) versus patients who undergo mpMRI-based active surveillance (Group 2). 3 years
- Secondary Outcome Measures
Name Time Method Percentage of patients in Group 1 versus Group 2 who remain on active surveillance from the time of randomization until the end of study participation. 3 years To compare adherence with active surveillance requirements in Group 1 versus Group 2.
To compare the rate of biopsy-related infections in Group 1 versus Group 2. 3 years To compare the missed rate of occult Gleason score ≥ 4+3 by template biopsy at end of study in Group 1 versus Group 2. 3 years
