Detaillierte Beschreibung
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.

- PSA </=20 ng/mL
- cT1-cT2c
- Either overall gleason score >/= 7 with Gleason grade 4 or 5 component localized to one lobe (i.e. right or left) OR overall Gleason score 6 with >/= half of systematic biopsy cores positive and >/= 50% of core involvement in at least one core
- Patient considering focal HIFU therapy
Exclusion Criteria:
- Previous local therapy for prostate cancer
- Inability to receive PET tracer
- Inability to receive MRI

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+) |

Negative Biopsy Rate (Number of Participants With Negative Biopsy)
Zeitfenster: 6 months following standard HIFU therapy
|
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.
