Abstract
Introduction: Prostate-specific antigen (PSA) kinetics (PSA velocity [PSAV] and PSA doubling time [PSADT]) are predictors of positivity in Choline PET/CT, but this correlation has not been correctly established in PSMA PET/CT. Objective: To evaluate the diagnostic correlation between PSA kinetics and positivity of 18F PSMA PET/CT in patients with relapsed prostate cancer (RPC). Material and methods: We performed an observational cross-sectional study of 54 patients with RPC that were evaluated with 18F-PSMA PET/CT. The concordance between 18F-PSMA PET/CT and PSA kinetics was analyzed. Results: The mean age was 68 ± 8 years. Time to relapse had a median (Q1-Q3) of 29 (8; 48) months. The trigger PSA
