Prostate Cancer Clinical Trial
FACBC Outcomes for Post Prostatectomy
Summary
Investigators will perform a study with 162 patients in whom there is a strong suspicion of prostate cancer that has returned to the body after having a prostatectomy. Half of these patients will have radiotherapy decision-making and delivery per the usual routine, and half of these patients will have the radiotherapy decision and volumes guided by the FACBC test (anti-1-amino-3-[18F]fluorocyclobutane-1-carboxylic acid (anti-3- [18F]FACBC). The major goal of the investigation is to see whether the FACBC improves the selection and the cancer control rates of post-surgery patients with a rising PSA who undergo radiotherapy.
Full Description
Prostate cancer is the most common solid tumor, with approximately 200,000 new cases diagnosed per year. Several different local therapies are available for treatment, including surgery and radiotherapy Significant advances have been made in the technical aspects of surgery and of radiotherapy which have improved both the cancer control outcomes as well as the morbidity of treatment. Despite these significant advances, approximately 30% of patients treated with definitive local therapy experience recurrent disease. Recurrent disease after prostatectomy usually manifests with rising PSA (blood test for prostate cancer). The PSA level is often of limited use in differentiating local recurrence (ie. recurrence in the prostate bed) from recurrence outside of the prostate bed ( extra-prostatic recurrence).
One PET radiotracer which has shown promise in the staging and restaging of patients with prostate carcinoma is anti-1-amino-3-[18F]fluorocyclobutane-1-carboxylic acid (anti-3-[18F]FACBC) which is a synthetic amino acid analog. FACBC demonstrated higher accuracy compared with 111Indium-capromab-pendetide in the restaging of patients with suspected recurrent prostate carcinoma.
The major goal in this proposed investigation is to use advanced molecular imaging to better guide post-prostatectomy decision making, in terms of guiding the decision to deliver radiotherapy, and in terms of the exact areas treated with radiotherapy.

Eligibility Criteria
Inclusion Criteria:
Adenocarcinoma of the prostate, post radical-prostatectomy Detectable PSA
ECOG/Zubrod Performance Status of 0-2
Negative technetium 99-m MDP or F-18 PET bone scan for skeletal metastasis
CT or MR scan of abdomen and pelvis which does not suggest presence of metastatic disease outside of the pelvis
Willingness to undergo pelvic radiotherapy.
Exclusion Criteria:
Contraindications to radiotherapy (including active inflammatory bowel disease or prior pelvic XRT)
Inability to undergo anti-3-[18F]FACBC PET-CT
Age under 18
Metastatic disease outside of pelvis on any imaging or biopsy
Prior invasive malignancy (except non-melanomatous skin cancer) unless disease free for a minimum of 3 years
Severe acute co-morbidity, defined as follows:
Unstable angina and/or congestive heart failure requiring hospitalization in the last 3 months
Transmural myocardial infarction within the last 6 months
Acute bacterial or fungal infection requiring intravenous antibiotics at the time of registration
Chronic Obstructive Pulmonary Disease exacerbation or other respiratory illness requiring hospitalization or precluding study therapy at the time of registration
Acquired Immune Deficiency Syndrome (AIDS) based upon current CDC definition; note, however, that HIV testing is not required for entry into this protocol. The need to exclude patients with AIDS from this protocol is necessary because the treatments involved in this protocol may be significantly immunosuppressive. Protocol-specific requirements may also exclude immunocompromised patients
