Bright White Light Therapy in Reducing Cancer-Related Fatigue and Depression in Advanced Prostate Cancer Patients Undergoing Treatment With ADT Combination Therapy

This phase II trial tests how well bright white light (BWL) therapy works in reducing cancer-related fatigue and depression in patients with prostate cancer that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced) and who are undergoing treatment with antiandrogen therapy (ADT) combination therapy. Combination treatment including ADT plus chemotherapy and androgen receptor (AR) targeted therapy or ADT plus AR targeted therapies work by reducing testosterone. Most prostate tumor cells rely on testosterone to help them grow; therefore, ADT combination therapy causes prostate tumor cells to die or to grow more slowly leading to improved overall survival in men with advanced prostate cancer when compared with ADT alone. However, lower levels of testosterone is also commonly associated with worsening fatigue and depression. If prolonged and severe, these complications can alter patient treatment plans, impacting not just quality of life, but leading to inadequate cancer control. BWL therapy is a type of phototherapy that utilizes bright white full-spectrum light, either through a light box or light therapy glasses to help regulate circadian rhythms. Circadian rhythms are physical, mental, and behavioral changes that follow a 24-hour cycle, including the sleep-wake cycle which can become disrupted in cancer patients undergoing treatment, leading to increased fatigue. Additionally, exposure to bright light may increase the production of serotonin, a neurotransmitter that is associated with mood regulation. BWL therapy with AYOpro light therapy glasses may serve as a supportive care measure for men with advanced prostate to help reduce fatigue, as well as improve mood and overall quality of life during ADT combination therapy to maintain cancer care without suffering complications of therapy.
