Chapter 45 • Fatigue affects most patients with cancer, regardless of the stage of disease or the type of anticancer therapy used. • Cancer-related fatigue (CFR) affects an estimated 80% to 90% of outpatients with cancer who receive either chemotherapy or radiation therapy. • CRF can be persistent in cancer survivors. • Determining the exact incidence requires standardized methods to define, diagnose, and measure CRF. • No standardized measurement tools exist except for International Classification of Diseases–10 criteria, which have not been widely adopted. • Using National Comprehensive Cancer Network guidelines, patients report levels of fatigue using a numeric rating scale of 0 to 10. This numeric rating scale is currently used as a screening tool.
