Supportive therapy of elderly cancer patients

Elderly cancer patients often require supportive care due to the physiologic decline of organs and apparatus linked with the aging process per se, and for the effects of tumor or of anticancer treatments. Pain and nutritional deficits are some clinical aspects requiring supportive care. Lack of studies on these latter topics does not allow an in depth analysis of the problem. The present review deals with literature concerning pain and nutritional problems in the general cancer population with emphasis on aspects typical for elderly cancer subjects. Physiologic and cancer–related changes in body composition, physical function and cognitive capacity of the elderly are presented and, when appropriate, linked with pathogenetic factors of pain and malnutrition, as well as their treatment. Pain demographic data, pain intensity evaluation and currently available techniques to provide pain relief such as etiologic treatment, analgesic pharmacotherapy and invasive analgesic procedures, are extensively discussed. Causes and assessment of malnutrition as well as available nutritional approaches such as oral, enteral and parenteral nutrition are also debated.
