Prostate-specific membrane antigen (PSMA) PET-CT imaging in the investigation and management of biochemical recurrence in prostate cancer.

208 Background: 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.
