[Cancer-related fatigue. Psychosocial support].

Cancer-related fatigue is a subjective sensation of uncontrollable physical, emotional and/or cognitive tiredness and weakness, which occurs in the context of cancer or cancer-treatment. Cancer-related fatigue occurs at all stages of cancer treatment and can persist long after medical treatment. It profoundly affects patients' quality of life and limits their personal, social, and occupational lives. Cancer-related fatigue is also associated with significant levels of distress, and it imposes financial burdens by limiting a patient's ability to work. Current psychosocial interventions with strong or sufficient evidence include physical training, cognitive-behavioral training, relaxation techniques, psychoeducation and patient education. This article gives an overview of currently available psychosocial interventions and information on their implementation.
