Nutrition in the care of patients with cancer cachexia.

Cancer cachexia, a progressive wasting syndrome experienced by approximately 80% of patients, is characterized by loss of adipose tissue and lean body mass. This complex metabolic process reflects both reduced nutrient availability and increased nutritional demand. Though cachexia is most commonly associated with particular tumours, no patient or tumour are excluded. This article provides an overview of cachexia and its pathophysiology and the factors contributing to its development before considering its impact on individuals. Emphasis is placed on the nutritional aspects of its management. [ABSTRACT FROM AUTHOR]
