What You Need to Know Before You Apply

What is the purpose of this trial?

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.

What Are the Treatments Tested in This Trial?

Interventions

  • Systemic Light Exposure
Trial Overview The study tests if systematic light exposure prevents frailty symptoms caused by hormone therapy in older men with prostate cancer. Frailty includes fatigue, slow walking speed, reduced activity levels, muscle loss and weakness. The trial involves questionnaires and actigraphy (movement monitoring) to assess the effects.
