Prostate‐specific antigen ‘bounce’ after permanent ¹²⁵ I‐implant brachytherapy in Japanese men: a multi‐institutional pooled analysis

Abstract

PSA bounce is a common phenomenon after (125)I-BT and occurred at a rate of 19-51% in the Japanese men who underwent (125)I-BT, depending on the definition used. It is more common in younger patients, and early PSA bounce should be considered when assessing a patient with a rising PSA level after (125)I-BT, before implementing salvage interventions. Furthermore, PSA bounce magnitude might be lower in Japanese than in Caucasian patients.
