Abstract:
We report a case of a 43-year-old man who underwent a radical prostatectomy 3 years before the procedure (June 2015) for a locally advanced Gleason 7(4 + 3) prostate adenocarcinoma (pT3aN0), with negative surgical margins, followed by salvage radiotherapy. He also underwent antiandrogen therapy for biochemical relapse (bicalutamide) from October 2016 through May 2017, but prostate-specific antigen continued to rise (2.5 ng/mL [December 2017] and 3.3 ng/mL [February 2018]). At this point, he underwent a Ga-prostate-specific membrane antigen PET/CT, and after multidisciplinary discussion, the therapeutic option chosen was image-guided salvage cryoablation.
