Metastatic Prostate Cancer with Charles Ryan, MD and William K. Oh, MD: Case 2 - Episode 7

William Oh, MD: Bone-Targeted Therapy

Would you consider bone-targeted therapy for this patient, and why?

This patient presented with metastatic prostate cancer to the bone. Traditionally we would add bone-targeted treatments in this type of setting. By bone-targeted treatments I mean bisphosphonates or RANK ligand inhibitor, drugs such as zoledronic acid, or denosumab. In hormone-sensitive prostate cancer patients, the evidence of benefit has never really been clearer, and, in fact, two large studies have not suggested that there’s a significant benefit to starting these treatments in the hormone-sensitive state. However, I do evaluate these patients in various ways.
