None of the above-the role of nutritional support in the cancer patient remains an important component of overall therapy. preoperative nutritional support should be given only to those patients who do not require an emergency operation and who have severe weight loss (> 15% of pre-illness body weight) and a serum albumen < 2.9 mg%. preoperative nutrition (enteral or parenteral) should not be given for longer than 7 to 10 days. enteral nutrition is always the preferred route of feeding cancer patients if the gi tract is functional. there are several benefits of using the bowel lumen for nutrient delivery. the trophic effects of enteral feeding on small bowel mucosa have been well described. the integrity of the mucosal lining is maintained and it may provide an effective barrier to intraluminal enteric organisms which might otherwise translocate into the systemic circulation. atrophic changes may be seen in the intestinal epithelium after several days of bowel rest; this atrophy is not reversed by currently available total parenteral nutrition solutions.
