Abstract: |
The nutritional assessment of cancer patients involves obtaining a comprehensive diet history, a physical exam, and laboratory data to determine nutritional status. Fad diets, as well as cancer diets and alternative approaches to curing disease can impact negatively on nutritional status. Other causes for impaired nutritional status include chewing and swallowing problems (oral cancers), pain, and gastrointestinal illness/malabsorption (stomach, intestinal, or pancreatic cancers). When oral feeding is not feasible secondary to dysphagia or pain, enteral feeding by tube or total parenteral nutrition are alternate modes of nutrient provision. Evidence still evades the fields of medicine and nutrition as to the effects of nutrition support on increasing tolerance to therapy, decreasing complications, and prolonging survival of the cancer patient.
