Clinical aspects of nutrition in advanced cancer.
Nutritional assessments of our patients with disseminated malignancies have revealed that the incidences of reported anorexia, decreased food intake, and weight loss range between 49 and 64%. It is therefore essential that a planned approach to the nutritional needs of patients with advanced cancer be part of routine oncology care. Our first step is a clinical assessment of the patient's nutritional state and diet, and a determination of caloric and nutrient needs. The potential tools available to the oncologist in the management of the undernourished cancer patient are many and include dietary counseling, food supplements (which contain vitamins and other micronutrients), stimulation of appetite, enteral nutrition, total parenteral nutrition, or a combination of these. The dietitian can be an invaluable component of the cancer care team, both in the inpatient and outpatient settings. An understanding of the role of each intervention will enable the physician to use available resources rationally and efficiently.
