The management of anorexia by patients with advanced cancer: a critical review of the literature.

This report presents the results of a critical review of the literature on the experience of anorexia (loss of appetite) by patients with advanced cancer. Although several studies have investigated this experience, the adaptive strategies used by patients to compensate for appetite loss remain poorly elucidated. Based on the small body of extant research, it was concluded that, in many instances, a gap exists between the ability of patients and caregivers to come to terms and deal realistically with the emotional and social consequences of patient anorexia. Patients generally appear to suffer greater discord as a result of this disparity, than from the direct psychological impact of anorexia. A greater understanding of the management of anorexia by patients is essential for the development of dietary and psychosocial interventions that would aid both patients and caregivers to cope with this common symptom.
