Recently, improving host defence mechanisms have become a target of interest. Immunonutrition aims at improving immunity, most likely providing key nutrients to maintain T-lymphocyte and other host defence. Aim : To evaluate the immunonutrition in cancer patients who are operated by digestive diseases and assess the cost-effectiveness of this supplementation. Methods: This study consisted of a systematic review of the literature based on reference analyses retrieved from current databases such as PubMed, Lilacs and SciELO. The search strategy was defined by terms related to immunonutrition [immunonutrition, arginine, omega-3 and nucleotides] in combination with [costs, cost-effective and cost-effectiveness] as well as [gastrointestinal cancer surgery, oesophageal, gastric or pancreatic surgery] in English, Portuguese or Spanish language. For cost analyses, currencies used in the manuscripts were all converted to American dollars (US$) in order to uniform and facilitate comparison. Six prospective randomized studies were included in this review. Conclusion: The cost-effectiveness was positive in most of studies, demonstrating that this diet can significantly reduce hospital costs in the North hemisphere. However, similar studies needed to be carried to determine such results among us.<\/jats:p>","DOI":"10.1590\/0102-6720201600020014","type":"journal-article","created":{"date-parts":[[2016,7,16]],"date-time":"2016-07-16T13:30:53Z","timestamp":1468675853000},"page":"121-125","source":"Crossref","is-referenced-by-count":15,"title":["COST-EFFECTIVENESS
