MRI/TRUS Fusion Guided Prostate Biopsy- An Improved Way to Detect and Quantify Prostate Cancer
MRI/TRUS Fusion Guided Prostate Biopsy- An Improved Way to Detect and Quantify Prostate Cancer. A Phase III Study

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 with the addition of an endorectal-coil probe and a 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 12-14 core biopsies.
This study will consist of comparison of the standard of care (TRUS guided prostate biopsy) with the protocol biopsy which consists of a TRUS guided prostate biopsy and a MR/US fusion tracked prostate biopsy. Each patient will act as their own control.

Genders Eligible for Study
Description
Inclusion Criteria:
- All patients must have a pre-operative MRI performed in accordance with our NSHSLIJ/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 conscious sedation (if procedure to be performed with conscious sedation, and without general anesthesia).
- 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 2 months of biopsy
- Able to tolerate a TRUS 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.
- Inability to hold breath, if procedure will be performed with conscious sedation, and without general anesthesia.
- Patients with pacemakers or automatic implantable cardiac defibrillators (contraindications to MRI)
- Patients with uncorrectable coagulopathies.

---|---|---|
Number of prostate lesions
Time Frame: Day 1
|
To determine if the number of prostate lesions identified by targeted (MR / US fusion biopsy) plus conventional biopsy is statitically greater than the number of lesions identified conventional biopsy alone.
The number of positive lesions identified by both techniques will be compared.
