The nutritional effects of cancer and its therapy
1980
Costa, G (Giovanni) | Donaldson, Sarah
Cancer induces metabolic and physiologic changes collectively known as cachexia which affect the nutritional status of the patient. Cachectic manifestations--weight loss, anorexia, altered taste perception, metabolic abnormalities, nutrient malabsorption, massive protein loss, anemia, and immunodeficiency--often resemble malnutrition. Cancer treatments, including surgery and radiation or chemotherapy, may also damage the patient's nutritional status by bringing about marked declines in oral food intake. These considerations emphasize the need for nutritional assessment in every patient with cancer, and reversal of cachexia by nutritional support whenever possible. Although there is a risk that hyperalimentation favors the tumor rather than the patient, most studies clearly demonstrate the benefits of increased delivery of nutrients to the malnourished cancer patient.
