ABSTRACT

As oncologists have become more effective in alleviating pain, nausea and depression, fatigue has emerged as the most important symptom suffered by cancer patients. Indeed, the current literature suggests that fatigue is currently the most important untreated symptom in cancer medicine. In recent surveys of patients and their caregivers, fatigue is more important for the quality of life than pain, nausea or depression. Yet these same surveys confirm that oncologists underestimate the importance of cancer related fatigue. This may be partly because patients often do not fully share the full nature of their concerns. When patients do raise the issue of fatigue, the physicians' recommendations are often non specific. However, recent research has shown that fatigue is not inevitable and untreatable, but a symptom amenable to differential diagnosis and specific intervention. Like pain, fatigue is intrinsically a subjective problem where the doctor relies on the patient's reporting. Weakness, exhaustion, lethargy and asthenia are all used as functional descriptions of fatigue. While these are descriptive terms, clinical research in the measurement and alleviation of fatigue requires reproducible measurement tools. Several studies already exist and have begun to explore this important area of symptom management.
