[Guidelines on nutritional support in patients with tumor].

Nutritional support for patients with tumor has been considered an important part of multidisciplinary treatment of tumor. It could improve the prognosis and quality of life for tumor patients when performed in a reasonable and effective way. Chinese Society for Parenteral and Enteral Nutrition (CSPEN) convened experts to develop these guidelines after many discussions and revisions according to standard procedures of guideline's development which were used worldwide. In order to develop these guidelines, we systematically reviewed the related global literature published in recent years, referred to other guidelines of national and international nutrition society, considered on expert opinion and their clinical experience in our country, and widely consulted the members of CSPEN and other related professionals. In the guideline, we firstly expounded metabolic characteristics and nutritional requirements in patients with tumor, and then raised 13 common questions existed in the practice of clinical nutrition, and provided 33 recommendations followed by systematic discussion. The guideline will help to standardize the clinical nutrition practice, provide reasonable and effective nutrition support, and further improve the prognosis and quality of life for tumor patients. We hope that the guideline release could provide theoretical guidance for nutritional support in patients with tumor in our country, and also make great contributions to much progress of clinical nutrition and tumor treatment in our country, and strengthen the multidisciplinary cooperation.肿瘤患者的营养支持已成为肿瘤多学科综合治疗的重要组成部分。合理、有效地提供营养支持对改善肿瘤患者的预后及生活质量具有积极作用。中华医学会肠外肠内营养学分会组织专家，按照当今国际上指南制定的标准流程，系统回顾近年来国内外发表的相关文献，参考各国和国际性营养学会的相关指南，综合我国专家意见和临床经验，并广泛征求本学会委员及相关专业人士的意见，多次组织讨论和修改，最终形成本指南。本指南首先系统阐述了肿瘤患者的机体代谢特点及营养需求，然后提出了肿瘤临床营养实践中常见的13个问题，给出了33条推荐意见，并进行了系统论述。本指南有助于规范肿瘤临床营养实践，为肿瘤患者提供合理、有效的营养支持，改善患者的预后及生活质量。希望本指南的发布能够为我国肿瘤患者的营养支持提供理论指导，为提高我国临床营养及肿瘤的综合诊治水平、加强多学科合作贡献力量。.
