Cancer anorexia-cachexia syndrome: psychological effect on the patient and family.

The majority of patients with advanced cancer experience weight loss, reduced appetite, fatigue, and weakness. Chronic nausea and early satiety may also occur. This constellation of symptoms is known as the cancer anorexia-cachexia syndrome. Together with cancer pain, cancer anorexia-cachexia syndrome has been identified as 1 of the 2 most frequent and devastating problems affecting individuals with advanced malignancies. Research examining the issue of cancer anorexia-cachexia syndrome has been conducted; however, such work is largely biomedical in orientation. In contrast, the psychologic dimensions of the cancer anorexia-cachexia syndrome experience from the perspective of terminally ill patients and their family members is less well explored or described. The ability to provide psychosocial support to patients and families requires that caregivers appreciate the psychologic effect of cancer anorexia and cachexia on these individuals. This article examines that effect in light of existing knowledge and discusses the clinical implications arising from this work.
