High-dose Vitamin D to prevent bone loss in older prostate cancer patients on hormone therapy

High-dose Vitamin D Supplementation for ADT-Induced Bone Loss in Older Prostate Cancer Patients

NIH-funded research University of Rochester · NIH-10983309

This study is looking at whether taking high doses of vitamin D can help older men with prostate cancer who are on hormone therapy keep their bones strong and improve their strength and balance, making it less likely for them to have fractures or falls.

What this research studies

This research investigates the effects of high-dose vitamin D supplementation on bone health in older prostate cancer patients undergoing androgen deprivation therapy (ADT). ADT can lead to significant bone mineral density loss and muscle mass reduction, increasing the risk of fractures and falls. The study aims to determine if administering high doses of vitamin D can mitigate these adverse effects, improve bone density, and enhance overall physical strength and balance. Participants will receive vitamin D supplementation and be monitored for changes in bone health and muscle function.

Who could benefit from this research

Good fit: Ideal candidates for this research are older prostate cancer patients aged 65 and above who are currently undergoing androgen deprivation therapy.

Not a fit: Patients who are not undergoing androgen deprivation therapy or are younger than 65 years old may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could help prevent bone loss and improve the quality of life for older prostate cancer patients receiving hormone therapy.

How similar studies have performed: Previous research has shown that high-dose vitamin D can effectively improve bone density in other populations, suggesting potential success for this approach in prostate cancer patients.
