Image-Guided (68Ga-PSMA-11 PET/CT) Prostate Biopsy for the Diagnosis of Prostate Cancer in Men With Prior Negative/Inconclusive Biopsy
About
This early phase I trial studies how well an image-guided prostate biopsy using the imaging agent 68Ga-prostate-specific membrane antigen (PSMA)-11 with a positron emission tomography/computed tomography (PET/CT) scan works in diagnosing prostate cancer in men with a prior negative or inconclusive prostate biopsy. PSMA is a protein that is found on the surface of prostate cancer cells. 68Ga-PSMA-11 is made up of a substance that binds to PSMA on tumor cells, linked with a radioactive substance that can then be seen on imaging scans such as PET/CT. 68Ga-PSMA-11 PET/CT-guided biopsy may help improve the detection rate of prostate cancer. This may help reduce over-diagnosis and over-treatment in men with low-risk prostate cancer and under-treatment in men with high-risk prostate cancer.
Eligibility
Inclusion Criteria:
- Men with suspicion of clinically significant prostate cancer with prior inconclusive, discordant or negative magnetic resonance imaging/ultrasound (MRI/US) fusion prostate biopsy
- Scheduled for a repeat transrectal ultrasound (TRUS) prostate biopsy by standard of care
- Focal 68Ga-PSMA-11 uptake within the prostate
Exclusion Criteria:
- Negative 68Ga-PSMA-11 uptake within the prostate (screening failure)
- Age < 18 and > 90 years
- Recurrent prostate cancer
- Inability to provide written informed consent
- Known inability to remain still and lie flat for the duration of the PET/CT (about 30 minutes)
