Contributors:  Liwei Jia


A man in his mid 60s had a prior history of prostatic adenocarcinoma (Gleason score 5+5=10, involving 12 cores). His PSA level initially declined to undetectable after introducing treatment with abiraterone + prednisone 1.5 years ago. He now presents with rising PSA level and has evidence of new bone metastases identifiable on CT imaging. A TURP was performed to relieve his urinary symptoms.
