Diagnostic Accuracy of 68Ga-PSMA-11 PET for Pelvic Nodal Metastasis Detection Prior to Radical Prostatectomy and Pelvic Lymph Node Dissection: A Multicenter Prospective Phase 3 Imaging Trial.
Summary
The investigators are imaging patients with prostate cancer using a new PET imaging agent (Ga-68-PSMA-11) in order to evaluate it's ability to detection prostate cancer in patients with high risk disease prior to prostatectomy.

Eligibility Criteria
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).
- Diagnostic CT or MRI as part of the PET study or performed within one month of PSMA PET.
- Karnofsky performance status of greater than 50 (or Eastern Cooperative Oncology Group (ECOG) /World Health Organization (WHO) equivalent).
- Age > 18.
- Ability to understand a written informed consent document, and the willingness to sign it.
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.
