Anyone flagged should see a dietitian.","summary":"MUST (UK), NRS-2002 (Europe), MST (Australia) are two-minute screens validated in oncology; the Patient-Generated Subjective Global Assessment (PG-SGA) is the oncology-specific assessment tool that scores weight history, intake, symptoms, function and examination. GLIM (2019) provides consensus diagnostic criteria for malnutrition (phenotypic: weight loss, low BMI, low muscle mass; aetiologic: reduced intake or inflammation). Screening at diagnosis and each treatment cycle is recommended by ESPEN, ASCO and ESMO; audits show it happens in a minority of clinics.","asOf":"2026-09-08","links":[{"label":"NCI Dictionary of Cancer Terms: malnutrition","url":"https://www.cancer.gov/publications/dictionaries/cancer-terms/def/malnutrition"},{"label":"Muscaritoli et al., ESPEN practical guideline: clinical nutrition in cancer (Clinical Nutrition 2021)","url":"https://doi.org/10.1016/j.clnu.2021.02.005"}],"tags":[],"related":[],"cancers":[],"sections":[],"technologies":["nutrition-screening-mnt","oncology-nutrition","geriatric-assessment","eras-perioperative-nutrition"],"targets":[],"drugs":[],"companies":[],"institutions":[],"pathways":[],"terms":["nutrition-impact-symptoms","sarcopenia","cachexia"],"trials":[],"people":[],"bottlenecks":["b-cachexia-supportive","b-care-fragmentation"],"keyPapers":["paper-muscaritoli-clin-nutr"],"journals":[],"dependsOn":[],"notes":[],"category":"Nutrition & lifestyle","wikipediaChecked":"2026-09-22"},"route":"/terms/malnutrition-screening/","neighbours":{"technology":[{"id":"ct-body-composition-sarcopenia","kind":"technology","name":"CT body composition and sarcopenia measurement","route":"/technologies/ct-body-composition-sarcopenia/"},{"id":"eras-perioperative-nutrition","kind":"technology","name":"Enhanced recovery (ERAS) and perioperative nutrition","route":"/technologies/eras-perioperative-nutrition/"},{"id":"enteral-parenteral-nutrition","kind":"technology","name":"Enteral and parenteral nutrition support","route":"/technologies/enteral-parenteral-nutrition/"},{"id":"g8-geriatric-screening","kind":"technology","name":"G8 geriatric screening tool","route":"/technologies/g8-geriatric-screening/"},{"id":"geriatric-assessment","kind":"technology","name":"Geriatric assessment","route":"/technologies/geriatric-assessment/"},{"id":"oncology-nutrition","kind":"technology","name":"Nutrition support and cachexia management","route":"/technologies/oncology-nutrition/"},{"id":"nutrition-screening-mnt","kind":"technology","name":"Oncology nutrition assessment and medical nutrition therapy","route":"/technologies/nutrition-screening-mnt/"}],"term":[{"id":"cachexia","kind":"term","name":"Cancer cachexia","route":"/terms/cachexia/"},{"id":"nutrition-impact-symptoms","kind":"term","name":"Nutrition impact symptoms","route":"/terms/nutrition-impact-symptoms/"},{"id":"pancreatic-palliation-obstruction-pain-nutrition","kind":"term","name":"Palliation in pancreatic cancer: biliary and duodenal stents, coeliac plexus block, enzymes and cachexia","route":"/terms/pancreatic-palliation-obstruction-pain-nutrition/"},{"id":"sarcopenia","kind":"term","name":"Sarcopenia","route":"/terms/sarcopenia/"},{"id":"weight-loss-and-fat-digestion-biliary","kind":"term","name":"Weight loss, fat digestion and enzymes with gallbladder cancer","route":"/terms/weight-loss-and-fat-digestion-biliary/"}],"bottleneck":[{"id":"b-cachexia-supportive","kind":"bottleneck","name":"Cachexia, toxicity and the limits of the patient","route":"/bottlenecks/b-cachexia-supportive/"},{"id":"b-care-fragmentation","kind":"bottleneck","name":"Fragmented care and guideline gaps","route":"/bottlenecks/b-care-fragmentation/"}],"paper":[{"id":"paper-muscaritoli-clin-nutr","kind":"paper","name":"ESPEN practical guideline: Clinical Nutrition in cancer","route":"/key-papers/paper-muscaritoli-clin-nutr/"}],"cancer":[{"id":"colorectal","kind":"cancer","name":"Colorectal cancer","route":"/cancers/colorectal/"},{"id":"pancreatic","kind":"cancer","name":"Pancreatic ductal adenocarcinoma","route":"/cancers/pancreatic/"}],"drug":[{"id":"pancrelipase","kind":"drug","name":"Pancrelipase (pancreatic enzyme replacement therapy)","route":"/drugs/pancrelipase/"}],"trial":[{"id":"prehab-trial","kind":"trial","name":"PREHAB: multimodal prehabilitation before colorectal cancer surgery","route":"/trials/prehab-trial/"}],"idea":[{"id":"idea-nl-dietitian-in-every-mdt","kind":"idea","name":"A dietitian in every gastrointestinal and head and neck tumour board","route":"/ideas/idea-nl-dietitian-in-every-mdt/"}],"roadmap":[{"id":"nutrition-lifestyle-roadmap","kind":"roadmap","name":"Diet, exercise and lifestyle roadmap: causes established → interventions that disappointed → exercise proven as treatment","route":"/roadmaps/nutrition-lifestyle-roadmap/"}]}}
