Validation of FACBC for Detection of Metastasis Among High-risk Prostate Cancer Patients With Presumed Localized Disease (EDRN-FACBC)
Validation of FACBC as an Early Indicator of Sub-clinical Metastatic Disease Among High-risk Prostate Cancer Patients With Presumed Localized Disease
Study Overview
Detailed Description
Approximately 50-80% of patients who are considered high-risk after being treated with definitive radical prostatectomy experience recurrent disease, often because of undetected extra-prostatic metastatic disease prior to treatment. There is increasing evidence that performing radical prostatectomy in patients with high-risk disease or locally advanced disease is feasible and has potential benefits in terms of local control, overall survival, and quality of life. Thus, improved imaging approaches for early detection of occult metastatic prostate cancer at the time of presentation could inform a directed treatment approach that would significantly improve patient outcomes, including use of extended lymphadenectomy as well as postoperative radiation therapy planning.
Amino acid transport is up-regulated in prostate and other cancers. Anti-1-amino-3-[18F]fluorocyclobutyl-1-carboxylic acid (FACBC) is a synthetic amino acid analog positron emission tomography (PET) radiotracer that has demonstrated promising results in the staging and restaging of prostate carcinoma, with high positive predictive value (PPV) in the identification of extraprostatic malignancy. Most of the prior studies of FACBC were in post-primary treatment recurrence, and this proposed trial will be the first comprehensive study to evaluate FACBC PET in detecting occult metastatic disease at initial diagnosis in patients with negative or equivocal conventional imaging, with the objective of developing a more effective primary treatment plan.
The goal of this study is to determine if FACBC PET will detect significant occult metastatic disease in patients with high risk primary prostate carcinoma who have negative or equivocal conventional imaging such as CT and/or MRI and bone scan. Participants will have a single scan prior to surgery for this study. Participants will be followed, through medical record reviews, for 10 years but no additional procedures related to this study will be performed.

Intervention / Treatment |
---|---|
Experimental: FACBC PET-CT Imaging
Individuals who have been diagnosed with primary prostate carcinoma and do not have definitive findings of systemic metastasis with conventional imaging will have a whole body FACBC PET-CT scan.
|
Participants will fast for 4 hours to normalize their neutral amino acid levels. One hour prior to the scan, participants will drink up to 450ml of standard oral contrast. Participants will lie on the scanning bed while the bed moves through the PET/CT scanner for the CT portion of the exam. After completion of the CT scan, approximately 10 units of FACBC will be injected for the PET scan portion of the exam. The bed will move through the scanner again and the PET portion of the exam will take 30 minutes. The entire visit will take about two hours. Standard of care procedures include conventional imaging (CT and/or MRI; bone scan and/or NaF PET per institutional standards) and radical prostatectomy with extended pelvic lymph node dissection.
