The purpose of this study is to identify specific chemotherapy-related changes in sleep stages/architecture that may relate to an increase in fatigue in individuals with cancer.
The researchers hypothesize that the fatigue experienced by cancer patients receiving chemotherapy is in part due to changes in restorative sleeping during the non-rapid eye movement cycles of sleep (i.e., delta activity).
Full description
Studies have shown a strong positive correlation between self-reported changes in sleep and cancer patients' fatigue, and also between an objective measure of sleep continuity, [i.e., actigraphy and polysomnography (PSG)] and self-reported fatigue. Chemotherapy disrupts normal sleep patterns, and fatigue, in the later stages of chemotherapy, may occur as a result of disturbed nocturnal sleep continuity. However, the causes of chemotherapy-related fatigue remain unknown, and whether or not abnormal sleep architecture contributes to this debilitating effect has yet to be explored. We believe that fatigue experienced by many cancer patients receiving chemotherapy is due, at least in part, to changes in delta activity [i.e., restorative sleep during the non-rapid eye movement (NREM) cycles of sleep]. A finding that slow wave sleep abnormalities play a significant role in fatigue would prompt further confirmatory studies and support controlled intervention studies.
Comparisons: In a clinical trial of individuals with cancer prior to, during, and after completion of chemotherapy, we will identify and compare specific chemotherapy-related changes in sleep stages/architecture that may relate to an increase in fatigue. These changes will be measured by actigraphy, PSG, and patient self-reporting techniques (e.g., sleep diaries, questionnaires).
The primary objective is to:
Secondary objectives are to:
Answers to these questions will provide information that will be helpful in developing potential targets for interventions to reduce fatigue.
