title: Assessment and maintenance of nutrition in older cancer patients.
abstract: Variables that the clinician can assess to determine the nutritional status of cancer patients include percent and rate of weight loss from usual body weight, current weight compared to calculated ideal body weight, and levels of appetite and food intake. Our studies show that two-thirds of patients with advanced cancer over the age of 65 have had some degree of weight loss, and that more than half are underweight, have loss of appetite, or complain of a decrease in food intake. Ongoing support and education, food supplementation, and attention to activity level may all contribute to preserve the patient's nutritional status and quality of life. Severe, persistent anorexia that does not respond to dietary counseling can be reversed with megestrol acetate. Enteral and parenteral nutrition have specific indications but should not be routinely used in anorectic patients.
