|Prostate Cancer||Drug: 18F-Fluciclovine||Phase 2|
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.

Imaging (comparing standard and experimental high resolution diffusion-weighted imaging [DWI] MRI with 18F-Fluciclovine)
- Number of biopsy-proven cancers that standard imaging (mpMRI) would have missed compared with high resolution diffusion-weighted imaging (DWI) PET-hrMRI on mapping MRI. [ Time Frame: At time of post-imaging biopsy ]Difference between sensitivities to identify prostate lesions.
- Negative biopsy rate [ Time Frame: 6 months following standard HIFU therapy ]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.
- Rate of high grade cancer [ Time Frame: 6 months following standard HIFU therapy ]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 absence of Gleason grade 4 or 5 in the untreated region.
