Spots Global Cancer Trial Database for FACBC Outcomes for Post Prostatectomy

Study Description

Brief 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.

Detailed 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. 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. 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.
