Quality of life and nutritional support in patients with cancer.

Nutritional support is often initiated in patients with cancer who are unable to meet their nutritional needs by the oral route. Much has been written about the effect of nutritional support on physiological outcomes in patients with cancer. However, less is known about the relationship between improvement of nutritional status and quality of life. Trends in the treatment of cancer highlight the need for an examination of home nutrition support and quality of life. The purpose of this article is to describe the state of knowledge about the relationship of home enteral and parenteral nutrition support and quality of life. Research exploring the dimensions of quality of life (physical functioning, psychological status, interpersonal relationships and social functioning, financial concerns, and symptoms, and complications of nutritional support) is presented. Implications for clinical practice and research are identified. The trend for increased numbers of patients on home nutrition support emphasizes the need to understand the patient's and family's experience in managing this treatment in the home.
