Testosterone Bounce in Degarelix-Treated Prostate Cancer
2026-09-16
A retrospective study of 120 patients identified testosterone bounce, defined by recovery from a nadir below 20 ng/dL to a later value of at least 20 ng/dL, as a marker associated with better overall and cancer-specific survival during degarelix therapy. The finding suggests that longitudinal testosterone behavior may complement PSA-based assessment, although prospective validation is needed before clinical implementation.
