Abstract Antiandrogen withdrawal response is an increasingly recognized entity in patients with metastatic prostate cancer. To our knowledge there have been no reports describing a durable radiologic improvement along with prostate-specific antigen PSA with discontinuation of the antiandrogen agent bicalutamide. We report a case in which a dramatic decline of serum PSA levels associated with a dramatic improvement in radiologic disease was achieved with bicalutamide discontinuation. Background Cancer of the prostate is the most prevalent cancer of American men 1 . At the time of diagnosis almost 50 of the patients have disease that extends beyond the prostate gland. .
