The aim of the study was to assess which factors may influence (11)C-choline PET/CT detection rate in a population of recurrent prostate cancer (PCa) patients listed for salvage radiation therapy (S-RT) in an early phase of biochemical relapse, to select which patients could obtain the most benefit by performing restaging (11)C-choline PET/CT before S-RT. ⋯ (11)C-choline PET/CT may be suggested before S-RT during the early phase of biochemical relapse, to select patients who may benefit from this aggressive treatment. Particularly, patients showing fast PSA kinetics or PSA increasing levels despite ongoing ADT should be studied with (11)C-choline PET/CT before S-RT, considering the higher probability to detect positive findings outside the pelvis.
