title: Advances in perioperative nutrition: cancer.
abstract: The role of perioperative nutritional support in the management of cancer patients remains controversial. The benefit of supplemental calories is not the only current issue: in fact, the route of delivery, composition of basic nutrients (carbohydrate, protein, fat), and the role of supplemental additives (arginine, glutamine, omega-3 fatty acids, nucleotides) in improving immune status and ultimate outcome have been the focus of much discussion. Emerging data suggest that the use of supplemental agents is associated with improvement in immune status in these patients, although there is little clear evidence that this improves outcome. Ongoing studies are aimed at defining the group of patients who would most benefit from nutritional interventions during the perioperative period.
