208Background: It is estimated that within ten years of primary treatment for prostate cancer up to 40% of patients post radical prostatectomy, and up to 50% of patients post radiotherapy will develop disease recurrence. While monitoring of PSA levels is informative of biochemical recurrence, it may precede radiologically detectable recurrence by months to years, and cannot differentiate local/regional recurrence from systemic disease. This represents a management dilemma for treating physicians. The incorporation of PET probes targeting prostate-specific membrane antigen (PSMA) for prostate cancer shows promise for improving the management of patients with prostate cancer, when used alongside existing imaging techniques, like CT, MRI and bone scans. Methods: Retrospective review of all patients referred from our institution for PSMA imaging was carried out. Baseline clinical features were determined and we analyzed impact of PSMA imaging on management outcomes and survival data. Results: 33 patients refe...
