Official title
A Randomized Trial Of The SYNC APP
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Fatigue is a major problem for cancer patients, and one that can persist long after treatment ends. Recent work has demonstrated that light therapy may mitigate or reduce fatigue levels in both cancer patients and cancer survivors. This protocol seeks to assess how lighting interventions distributed through a mobile app affect fatigue, sleep, and quality of life across three populations of cancer patients: breast cancer and prostate cancer, and patients who have undergone autologous hematopoietic stem cell transplant (HSCT). Participants will be randomized 1:1 to either the interventional SYNC app or to a control app.
