68Ga-PSMA-11 PET/MRI in Finding Tumors in Patients With Intermediate or High-Risk Prostate Cancer Undergoing Surgery
Not Recruiting
Trial ID: NCT02678351
Purpose
This phase 2-3 trial studies the utility of 68-gallium (68Ga)-prostate-specific membrane antigen 11 (PSMA-11) positron emission tomography/magnetic resonance imaging (PET/MRI) to find tumors in patients with prostate cancer who are undergoing resection surgery for prostate cancer that is prognostically expected to spread quickly (intermediate-risk) or is likely to come back or spread (high-risk). Diagnostic procedures, such as PET/MRI, may help find and diagnose prostate cancer, and reveal out how far the disease has spread. Radioactive drugs, such as 68Ga-PSMA-11, may bind to tumor cells that have specific receptors, and may allow doctors to see smaller tumors than the standard of care contrast-enhanced computed tomography (CT) or MRI scan.

Eligibility
INCLUSION CRITERIA
* Biopsy-proven prostate adenocarcinoma
* Planned prostatectomy with lymph node dissection
* Intermediate- to high-risk disease (as determined by elevated prostate-specific antigen (PSA) \[PSA \> 10\], T stage \[T2b or greater\], Gleason score \[Gleason score \> 6\] or other risk factors)
* Karnofsky performance status of ≥ 50 \[or Eastern Cooperative Oncology Group (ECOG)/World Health Organization (WHO) equivalent\]
* Diagnostic CT or MRI performed within 90 days of the research PET
* Able to provide written consent
ExCLUSION CRITERIA
* Patients not capable of getting PET study due to weight, claustrophobia, or inability to lay still for the duration of the exam
* Neoadjuvant chemotherapy or radiation therapy prior to prostatectomy, including focal ablation techniques (HiFu)
* Androgen deprivation therapy or other neoadjuvant treatments prior to PET imaging and surgery
* Metallic implants (contraindicated for MRI)
Intervention(s):
drug: 68Ga-PSMA-11
