2016年7月16日，營養(yǎng)飲食學會官方期刊《營養(yǎng)飲食學會雜志》在線發(fā)表阿巴拉契亞州立大學、瑪麗·格里利醫(yī)學中心、墨西哥總醫(yī)院（墨西哥城綜合醫(yī)院）、戴爾兒童血液與癌癥中心、營養(yǎng)飲食學會起草的《成人腫瘤循證營養(yǎng)實踐指南》，全文共61頁。

　　2012年，成立于1917年的美國營養(yǎng)師協(xié)會（American Dietitian Association，ADA）正式更名為營養(yǎng)飲食學會（Academy of Nutrition and Dietetics）, 新名稱的縮寫為：A.N.D.（請記得在字母之間加點，而不要寫成：AND）。官方網(wǎng)站地址仍為：www.eatright.org

　　該學會下屬的飲食教育認證委員會（Commission on Accreditation for Dietetics Education，CADE）是營養(yǎng)專業(yè)教育項目的認證機構(gòu)，主要負責注冊營養(yǎng)師（Registered Dietitian，RD）和注冊飲食技師（Dietetic Technician Registered，DTR）的認證。2011年更名為營養(yǎng)飲食教育認證委員會（Accreditation Council for Education in Nutrition and Dietetics，ACEND），主要負責注冊飲食營養(yǎng)師（Registered Dietitian Nutritionist，RDN）和注冊營養(yǎng)飲食技師（Nutrition and Dietetic Technician Registered，NDTR）的認證。該委員會受美國教育部認可，且是專業(yè)與職業(yè)認證委員會的一員，凡通過該機構(gòu)認證的營養(yǎng)學項目均為正規(guī)項目。

　　此外，美國還有：成立于1959年的美國營養(yǎng)學院（American College of Nutrition，ACN），2005年由美國臨床營養(yǎng)學會（American Society for Clinical Nutrition）美國營養(yǎng)科學學會（American Society for Nutritional Sciences）國際營養(yǎng)學會（Society for International Nutrition）合并而成的美國營養(yǎng)學會（American Society for Nutrition，ASN），成立于1975年的美國腸外腸內(nèi)營養(yǎng)學會（American Society for Parenteral and Enteral Nutrition，ASPEN），需要注意區(qū)別。

　　癌癥是用于描述一組100多種多因素疾病的術語，其中的異常細胞不受控制地增殖，而且能夠轉(zhuǎn)移到機體其他部位并侵襲健康組織【1】。癌癥死亡數(shù)量自20世紀90年代逐漸下降，癌癥幸存者數(shù)量上升【2】。據(jù)美國國家癌癥研究所（NCI）估計，2016年將有168.521萬例新診斷病例和59.569萬例死亡。基因和環(huán)境之間復雜的相互作用促進了癌癥的發(fā)生【3】。盡管營養(yǎng)狀況影響癌癥的許多具體途徑仍不清楚【4】，但是人們已認識到營養(yǎng)在癌癥預防和治療中起重要作用【4-8】。

　　2007年，營養(yǎng)飲食學會在證據(jù)分析庫（EAL）上發(fā)布了針對特定類型癌癥及其治療的營養(yǎng)干預相關指南建議。2010年，新的證據(jù)分析工作組建立，對原指南進行補充，2013年11月發(fā)布于EAL。當前的指南主要關注成人腫瘤患者廣泛的腫瘤營養(yǎng)實踐。雖然這些建議是為注冊飲食營養(yǎng)師（RDN）而寫，但是其他人可能發(fā)現(xiàn)有幫助。

　　由工作組制定的指南，首先根據(jù)EAL相關系統(tǒng)回顧作出建議，然后概述本學會以外組織的指南作出的建議【9-11】。后者被列入以進一步拓展循證建議的范圍。最后，對基于共識建議的簡要回顧，將進一步指導在該領域中營養(yǎng)研究較少或研究難以闡明的RDN。

　　結(jié)論聲明和建議的制定

　　整個項目遵循本學會的5步系統(tǒng)回顧流程【12】。腫瘤工作組主要針對成人腫瘤營養(yǎng)有足夠營養(yǎng)狀況和營養(yǎng)干預相關證據(jù)的4個領域：

• 營養(yǎng)不良篩查和營養(yǎng)評定工具的有效性；

• 營養(yǎng)狀況與發(fā)病率和死亡率的相關性；

• 醫(yī)學營養(yǎng)療法（MNT）對化療（CT）和放療（RT）患者的影響【13】；

• 癌癥惡病質(zhì)、包含魚油（特別是二十碳五烯酸[EPA]）的醫(yī)學食品補充劑（MFS）和飲食補充劑對體重和瘦體重（LBM）的影響。

Cancer is a term used to describe a group of more than 100 multifactorial diseases in which abnormal cells reproduce in an uncontrolled manner and are able to spread to other parts of the body and invade healthy tissues.【1】Numbers of cancer-related deaths have fallen steadily since the 1990s, and the number of cancer survivors has increased.【2】The National Cancer Institute has estimated that 1,685,210 new cases will be diagnosed and 595,690 deaths will occur in 2016.2 Cancers develop from complex interactions between genes and the environment.【3】Although many of the specific pathways by which nutritional status can impact cancer remain poorly understood,【4】it is well recognized that nutrition plays important roles in cancer prevention and treatment.【4-8】

In 2007, the Academy of Nutrition and Dietetics (Academy) published guideline recommendations on the Evidence Analysis Library (EAL) related to nutrition interventions for specific types of cancer and cancer treatments. In 2010, a new evidence analysis workgroup was formed to supplement the original guideline, which was subsequently published on the EAL during November 2013. The current guideline focuses on comprehensive oncology nutrition practice for the care of adult patients with cancer. Although the recommendations are written for registered dietitian nutritionists (RDNs), others may find them helpful.

The guideline developed by the workgroup will be reviewed, beginning with the recommendations that are based on the related EAL systematic review, followed by a brief review of recommendations based on organization guidelines outside of the Academy.【9-11】The latter were included to further expand the scope of the evidence-based recommendations. Finally, a brief review of the consensus-based recommendations will be provided to further guide the RDN, where there is less nutrition research or the research is difficult to elucidate.

Development of Conclusion Statements and Recommendations

The Academy's 5-step systematic review process【12】was followed throughout the project. The Oncology Workgroup chose to principally target four areas of oncology nutrition in adults where there was an adequate pool of evidence related to nutritional status and nutrition interventions:

• validity of malnutrition screening and nutrition assessment tools;

• the association among nutritional status and morbidity and mortality outcomes;

• the effect of medical nutrition therapy (MNT)【13】on patients undergoing chemotherapy (CT) and radiation treatment (RT); and

• cancer cachexia and the effect of dietary supplements and medical food supplements (MFS) containing fish oil (specifically eicosapentaenoic acid [EPA]), on body weight and lean body mass (LBM).
