Official title
Light Therapy to Prevent Frailty in Older Men With Prostate Cancer on Hormonal Therapy: A Pilot RCT
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This pilot trial studies how well systemic light exposure works in preventing frailty in older patients with prostate cancer on hormonal therapy. Hormone therapy causes many symptoms of frailty in older men including fatigue, slower time to walk a specified distance, reduced activity levels, loss of lean muscle, and muscle weakness. It is not yet known if systemic light exposure may reduce frailty in older prostate cancer patients.
