MR/TRUS Fusion Guided Prostate Biopsy
MR/TRUS Fusion Guided Prostate Biopsy- An Improved Way To Detect And Quantify Prostate Cancer
Study Overview
Status
Conditions
Detailed Description
The efficacy of targeting lesions for surgery may be limited by the visibility of a target during the procedure. The successful outcome of surgical intervention depends upon accurate device placement, which may be very challenging in certain settings, such as when a kidney tumor only is visible for a brief moment during the transient arterial phase of a contrast injection, and soon disappearing on dynamic imaging.
Historically, prostate cancer was diagnosed by digitally guided trans-rectal prostate biopsies. With PSA (Prostate Specific Antigen) screening and improvements in ultrasonography, trans-rectal ultrasound (TRUS) guided prostate biopsy have become the standard of care to screen and diagnose localized prostate cancer. Standard US 12-14 core prostate biopsy is now common practice, detecting cancer in 27% to 44% of patients.
Prostate MR imaging at 3 Tesla magnet dramatically improves diagnostic utility dramatically but biopsies are difficult, time-consuming, and require specialized equipment, which increases the cost significantly.
To meet this challenge TRUS images are overlaid on a previously obtained prostate MRI, combined with an electromagnetic tracking system. The urologist then performs directed prostate biopsies at MR-identified targets in addition to the standard prostate biopsies.
This study will consist of comparison of the standard of care prostate biopsy with the protocol biopsy which consists of a US guided prostate biopsy and a MR/US fusion tracked prostate biopsy. Each patient will act as their own control.

Participation Criteria
Eligibility Criteria
Ages Eligible for Study
Accepts Healthy Volunteers
Genders Eligible for Study
Description
Inclusion Criteria:
- All patients must have a pre-operative MRI performed in accordance with the MT Sinai/NIH MR prostate imaging guidelines.
- Age greater than 18 years.
- No serious concurrent medical illness that would preclude the patient from making a rational informed decision on participation.
- The ability to understand and willingness to sign a written informed consent form, and to comply with the protocol. If in question, an ethics consult will be obtained.
- Ability to tolerate sedation and or general anesthesia if required.
- PSA >2.5 or Abnormal digital rectal exam or current recommendations for biopsy from the American Urological Association
- Pre-biopsy prostate MRI as described above, showing targetable lesions within 4 months of biopsy
- Able to tolerate a ultrasound guided biopsy
Exclusion Criteria:
- Patients with an altered mental status that precludes understanding or consenting for the biopsy procedure will be excluded from this study.
- Patients unlikely able to hold reasonably still on a procedure table for the length of the procedure.
- Patients with pacemakers or automatic implantable cardiac defibrillators (contraindications to MRI)
- Patients with uncorrectable coagulopathies.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Incidence of Prostate Cancer
Time Frame: Day 0 - day of procedure
|
Incidence of diagnosing subjects with prostate cancer with MR visible lesions
|
Day 0 - day of procedure
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Incidence of adverse events
Time Frame: 1 month
|
the incidence of adverse events occurring after a targeted and ultrasound guided prostate biopsy
|
1 month
|
Pirads score
Time Frame: 1 month
|
The Prostate Imaging Reporting and Data System (PIRADS) score classifies MRI lesions on a scale from 1 to 5, which reflects their level of suspicion from least to most.
Higher score indicates more suspicion.
|
1 month
|
Gleason score
Time Frame: 1 month
|
The Gleason Score ranges from 1-5 and describes how much the cancer from a biopsy looks like healthy tissue (lower score) or abnormal tissue (higher score).
Sum of the gleason grade of the most predominant tumor pattern and a second gleason grade of the second most predominant pattern.
Full score from 2 to 10, with higher score indicating more clinically significance.
