Outcomes

Primary Outcome Measures

Number of Biopsy-proven Cancers (Gleason 6+) That Standard Imaging (mpMRI) Would Have Missed Compared With High Resolution Diffusion-weighted Imaging (DWI) PET-hrMRI on Mapping MRI.

A Gleason score of 6 is low grade, 7 is intermediate grade, and a score of 8 to 10 is high grade cancer. The Prostate Imaging Reporting and Data System (PI-RADS) is used to report how likely it is that a suspicious area is a clinically significant cancer. PI-RADS scores range from 1 (most likely not cancer) to 5 (very suspicious). Difference between sensitivities to identify prostate lesions. This is analyzed by the number of biopsy-proven cancerous zones (Gleason 6+) that mpMRI missed compared to PET or hrMRI (PIRADS) compared as follows: mpMRI vs hrMRI and PET (PIRADS 3-5 & Gleason 7+) mpMRI vs hrMRI or PET (PIRADS 3-5 & Gleason 7+) mpMRI vs hrMRI and PET (PIRADS 4-5 & Gleason 7+) mpMRI vs hrMRI or PET (PIRADS 4-5 & Gleason 7+) mpMRI vs hrMRI and PET (PIRADS 3-5 & Gleason 6+) mpMRI vs hrMRI or PET (PIRADS 3-5 & Gleason 6+) mpMRI vs hrMRI and PET (PIRADS 4-5 & Gleason 6+) mpMRI vs hrMRI or PET (PIRADS 4-5 & Gleason 6+)

Secondary Outcome Measures

Negative Biopsy Rate (Number of Participants With Negative Biopsy)

A Gleason score of 6 is low grade, 7 is intermediate grade, and a score of 8 to 10 is high grade cancer. The Prostate Imaging Reporting and Data System (PI-RADS) is used to report how likely it is that a suspicious area is a clinically significant cancer. PI-RADS scores range from 1 (most likely not cancer) to 5 (very suspicious). Following the tumor mapping study, patients with high grade disease (i.e. Gleason grade 4 or 5) in one lobe undergo hemigland or focal HIFU of that lobe. Patients would then undergo repeat prostate biopsy to assess the negative biopsy rate in the treated region.

5. Study Description

Brief Summary

This prospective trial aims to determine if enhanced prostate imaging using two novel imaging technologies (high resolution DWI and 18F-fluciclovine PET-MRI) will detect prostate cancers not seen on standard multiparametric prostate MRI in patients considered candidates for focal HIFU.

Detailed Description

This is a prospective trial to evaluate the effectiveness of 18F-fluciclovine PET-hrMRI versus standard mpMRI at identifying prostate cancer targets for HIFU therapy. Participants with clinically localized, unilateral high grade prostate cancer (Gleason score 7-10 prostate cancer localized to one lobe on prior biopsies) OR at high risk for having unrecognized high grade prostate cancer (overall Gleason score 6 with > half of systematic biopsy cores positive and > 50% of core involvement in at least one core), interested in HIFU would receive both a standard mpMRI and 18F-fluciclovine PET-hrMRI. Participants would then undergo a mapping biopsy using a standard sextant template plus MRI/US-fusion targeted biopsy of any lesion suspicious lesion on mpMRI or PET-hrMRI.
