Timing of Post-prostatectomy PSMA Imaging

Official Title

A Phase II Randomized Feasibility Study Comparing Early Salvage Radiation Therapy Versus Surveillance With Delayed Repeat PSMA PET/CT Imaging in Patients Presenting With Early Biochemical Relapse of Prostate Cancer Following Radical Prostatectomy


The investigators will randomize patients presenting with early BCR with a negative baseline PSMA PET/CT, to upfront SRT or surveillance. Early BCR is defined as a PSA relapse of >0.1 to <0.3 ng/mL. Patients in the surveillance arm will be monitored with PSA every 3 months. A repeat PSMA PET/CT will be undertaken when the PSA reaches a target level of >0.5 to <1.0 ng/mL. Both early radiation treatment and surveillance with repeat PSMA PET/CT imaging are within patterns of practice locally; therefore, the investigators believe that there is clinical equipoise on this subject.
