Q

38
What is the treatment for high grade/metastatic prostate cancer?
- GnRH/LHRH agonists (Leuprolide and Goserelin) - bicalutamide/flutamide (Anti-androgen therapy) given 3 days before LHRH agonists and continued for a week after. -GnRH/LHRH antagonist (Degarelix) - reduction in circulating LH and ↓ synthesis of testosterone.
