High Resolution PET-MRI Before Prostate Cancer HIFU

2021年2月2日 更新者:Timothy J. Daskivich

High-Resolution, 18F-fluciclovine PET-MRI for Mapping Prostate Cancer in Patients Considering Focal High-Intensity Focused Ultrasound (HIFU) Therapy

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.

详细说明

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.

大体时间:At time of post-imaging 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). 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+)

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.
