Prostate Cancer Clinical Trial
Radiolabeled Gallium-68 (68Ga-PSMA) for PET/CT Imaging to Detect Prostate Cancer
Summary
The purpose of the study is to find out whether imaging of the prostate with a new molecule called 68Ga-PSMA can find prostate cancer. 68Ga-PSMA has been shown in a large number of patients to be useful to find recurring prostate cancer following initial cancer treatment. This study is performed to test 68Ga-PSMA whether it can be used to find prostate cancers that would be considered in need for treatment.
Full Description
In this study, two different imaging tests are being compared: a) 68Ga-PSMA Positron Emission Tomography (PET)/Computed Tomography (CT) and b) Magnetic Resonance Imaging (MRI) of the prostate gland. Participants already have received the MRI, and the results were either suspicious of or definitive for prostate cancer. Both tests (MRI and 68Ga-PSMA PET/CT) are expected to show tumor tissue when more aggressive, but one test could be more accurate than the other test.
Another important question is whether these imaging tests will perform as good or better than prostate biopsies in finding all prostate cancer lesions in need for treatment. If imaging would be comparable or better than biopsies, then imaging may be able to replace invasive biopsies for some indications in the future.
To investigate these questions, participants are asked to undergo a 68Ga-PSMA PET/CT before a planned prostate biopsy procedure. After the biopsy procedure is performed, investigators will compare the imaging results from 68Ga-PSMA with those from the MRI and determine which test is more accurate.
Eligibility Criteria
