Objective:To screen and extract relevant evidence on the management of malnutrition in pediatric cancer patients and provide a best evidence summary.Methods:A systematic search was conducted across multiple websites and databases, including UpToDate, BMJ Best Practice, WHO website, Guidelines International Network, National Institute for Health and Care Excellence, National Guideline Clearinghouse, PubMed, Web of Science Core Collection, Embase, Cochrane Library, China National Knowledge Infrastructure, China Biology Medicine disc, Wanfang Data and others, for evidence on nutritional management of malnutrition in pediatric cancer patients. The search included literature from inception to August 31, 2023. Literature was selected following strict inclusion and exclusion criteria by researchers trained in evidence-based nursing courses. The quality of the selected literature was evaluated, and evidence was extracted and summarized.Results:A total of 11 articles were included, comprising two clinical decision papers, three guidelines, one evidence summary, two systematic reviews, and three expert consensus documents. The evidence was summarized into 24 evidence across five main areas: multidisciplinary team approach, nutritional risk screening and assessment, nutrient intake, dietary and nutritional education, and enteral and parenteral nutrition support.Conclusions:This study provides a best evidence summary for the nutritional management of malnutrition in pediatric cancer patients, offering evidence-based support for clinical practice among healthcare professionals.
