Abstract
PURPOSE: Cancer is a disease of the elderly: 60 % of tumours occur in patients aged 65 years or older. Cancer-related fatigue is a common symptom experienced by cancer patients and cancer survivors that profoundly affects all aspects of the quality of life. Although it has been estimated that up to 70 % of elderly with cancer experience fatigue, this symptom is still largely ignored in ageing population.

METHODS: We performed a systematic review of the literature identified by MEDLINE.

RESULTS: The relationship between ageing process and pathogenesis of cancer-related fatigue is still not fully understood.

CONCLUSIONS: Ageing is associated with an increased prevalence of chronic diseases, decreased functional reserve in multiple organ systems and enhanced susceptibility to stress. Ageing and the concomitant presence of a condition of frailty may predispose to the presence of fatigue. Nevertheless, only few studies have to date specifically assessed the impact of fatigue in the geriatric population. Since cancer-related fatigue is a peculiarly debilitating condition characteristic of elderly cancer patient population, we suggest the early recognition and thorough evaluation of the symptom fatigue, its co-existing causes (i.e. anaemia, mood disorders and sleep disturbances) and co-morbidities (i.e., endocrine disorders, metabolic, cardiovascular and liver diseases).
