Cancer-related fatigue is reported by patients to be the most distressing and persistent symptom experienced during and after treatment. Unrelieved fatigue often accompanies other symptoms and leads to decreased physical functioning and lower health-related quality of life. Various factors, including daytime sleepiness and sleep disturbances, have been reported to influence perceptions of fatigue. This article shares current knowledge about the relationships among cancer-related fatigue, sleep disturbances, and daytime sleepiness, and makes recommendations for routine screening, assessment, and interventions to modify fatigue through optimizing sleep quality in adult cancer patients. Evidence is reviewed for nonpharmacologic and pharmacologic interventions for optimizing sleep quality in patients with acute or chronic insomnia secondary to medical illnesses, including cancer. A summary of interventions is presented that focuses on optimizing sleep quality in attempt to lower fatigue. These interventions may be helpful for adult cancer patients experiencing insomnia but will require further testing to establish their efficacy in this population. Recommendations for research are provided, including the need to increase knowledge on the relationships among fatigue, sleep disturbances, daytime sleepiness, and other symptoms in various disease sites, stages, and treatments of cancer and the need for further testing of the measurements used for the evaluation of sleep quality in clinical practice and research.

NCCN convened a committee of experts to make recommendations for future studies of cancer-related fatigue (CRF). The committee reviewed the current data on the incidence, clinical measurement, and treatment of CRF. The assessment of fatigue is largely derived from self-report questionnaires that address the symptom of fatigue, and do not correlate the presence of fatigue with change in physical activity. The committee developed a self-report questionnaire, NCCN Fatigue and Contributing Factors Inventory, which incorporates assessments of fatigue, pain, difficulty sleeping, distress, physical activity, and concurrent medications. A clinical research study using this measure in conjunction with the NCCN Breast Cancer Outcomes Database Project is planned. The committee noted a strong interaction among fatigue, pain, difficulty sleeping, and distress and recommended that future clinical research address these interactions.

Cancer-related fatigue is defined as a distressing, persistent, subjective sense of physical, emotional, and/or cognitive tiredness or exhaustion related to cancer or cancer treatment that is not proportional to recent activity and interferes with usual functioning. It is one of the most common side effects in patients with cancer. Fatigue has been shown to be a consequence of active treatment, but it may also persist into posttreatment periods. Furthermore, difficulties in end-of-life care can be compounded by fatigue. The NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for Cancer-Related Fatigue provide guidance on screening for fatigue and recommendations for interventions based on the stage of treatment. Interventions may include education and counseling, general strategies for the management of fatigue, and specific nonpharmacologic and pharmacologic interventions. Fatigue is a frequently underreported complication in patients with cancer and, when reported, is responsible for reduced quality of life. Therefore, routine screening to identify fatigue is an important component in improving the quality of life for patients living with cancer.
