Cost-effectiveness of Perioperative Immunonutrition in Gastrointestinal Oncologic Surgery: a Systematic Review
نویسندگان
چکیده
INTRODUCTION Costs, length of hospital staying and morbidity are frequently and significantly increased as a result of infections and other complications following surgical procedure for gastrointestinal tract cancer. 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. INTRODUÇÃO Custos, tempo de hospitalização e morbidade estão frequentemente aumentados na presença de infecções e outras complicações decorrentes de procedimentos cirúrgicos para o câncer gastrointestinal. Recentemente, a melhora de mecanismos de defesa do hospedeiro tem se tornado um alvo de interesse. Nutrição adequada está fortemente relacionada com competência imune e redução de infeções. Imunonutrição objetiva a melhora da imunidade, principalmente para manutenção de linfócitos-T e outras defesas. OBJETIVO Avaliar a imunonutrição em pacientes oncológicos que são operados por doenças do aparelho digestivo e avaliar a relação custo-eficácia desta suplementação. MÉTODOS Revisão sistemática da literatura baseada nas bases de dados PubMed, Lilacs e SciELO. A busca foi realizada com combinação de descritores em inglês e português relacionados ao tema da revisão: [immunonutrition, arginine, omega-3, nucleotides] combinado com [costs, cost-effective, cost-effectiveness] e [gastrointestinal cancer surgery, oesophageal, gastric or pancreatic surgery]. Para análise de custos, moedas usadas nos artigos foram todas convertidas para dólar americano. Seis estudos randomizados prospectivos foram incluídos nesta revisão. CONCLUSÃO O custo-benefício foi positivo na maioria dos estudos, sugerindo que este tipo de dieta reduz significativamente os custos hospitalares nos países do hemisfério norte. Contudo, estudos similares de custo-benefício devem ser realizados para definir o real custo-benefício em nosso meio.
