A combination of nutrition-impact symptoms, reduced oral intake and systemic inflammation lead to poor tolerance to treatment, diminished quality of life and reduced survival. Systemic inflammation is a hallmark of cancer-associated malnutrition and contributes to loss of lean mass and abnormal body composition phenotypes (sarcopenia, cachexia and low muscle density) which may coexist with overweight and obesity. Malnutrition screening tools are widely used to identify patients at risk; however, traditional weight and BMI-based instruments such as the Malnutrition Screening Tool (MST) and Malnutrition Universal Screening Tool (MUST) frequently misclassify patients with cancer as well-nourished. These tools fail to account for nutrition-impact symptoms, inflammation and muscle wasting. Although obesity is an established cancer risk factor, 40\u201360% of patients with metastatic disease remain overweight or obese during treatment. When screening tools are BMI-based, high fat stores mask muscle wasting, leading to misclassification of nutritional risk and delayed dietetic referrals. To improve detection, screening tools should incorporate patient-reported symptoms, inflammatory markers and body composition assessment, enabling earlier, proactive nutritional care. Alternatively, it may be time to acknowledge that all cancer patients are inherently \u2018at-risk\u2019 of malnutrition and to prioritise universal access to dietetic support from diagnosis through treatment. This review summarises current malnutrition screening and assessment practices in oncology and outlines key considerations for future research and clinical practice.<\/jats:p>","DOI":"10.1017\/s0029665126102195","type":"journal-article","created":{"date-parts":[[2026,1,13]],"date-time":"2026-01-13T07:06:59Z","timestamp":1768288019000},"page":"1-10","update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":4,"title":["Appetite for change \u2013 the need to revisit malnutrition screening and assessment in oncology"],"prefix":"10.1017","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7811-8824","authenticated-orcid":false,"given":"Clodagh","family":"Scannell","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/03265fv13","id-type":"ROR","asserted-by":"publisher"}],"name":"University College Cork"},{"id":[{"id":"https:\/\/ror.org\/03265fv13","id-type":"ROR","asserted-by":"publisher"}],"name":"University College Cork"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Erin Stella","family":"Sullivan","sequence":"additional","affiliation":[{"name":"King\u2019s College London"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4330-9705","authenticated-orcid":false,"given":"Aoife","family":"Ryan","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/03265fv13","id-type":"ROR","asserted-by":"publisher"}],"name":"University College Cork"},{"id":[{"id":"https:\/\/ror.org\/03265fv13","id-type":"ROR","asserted-by":"publisher"}],"name":"University College Cork"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2026,1,13]]},"reference":[{"key":"S0029665126102195_ref25","doi-asserted-by":"publisher","DOI":"10.1002\/jcsm.12420"},{"key":"S0029665126102195_ref38","doi-asserted-by":"publisher","DOI":"10.1038\/sj.ejcn.1601412"},{"key":"S0029665126102195_ref31","doi-asserted-by":"publisher","DOI":"10.1017\/S0029665125100761"},{"key":"S0029665126102195_ref36","doi-asserted-by":"publisher","DOI":"10.1007\/s11764-018-0687-7"},{"key":"S0029665126102195_ref2","doi-asserted-by":"publisher","DOI":"10.1016\/j.clnu.2016.07.015"},{"key":"S0029665126102195_ref8","doi-asserted-by":"publisher","DOI":"10.1016\/j.advnut.2024.100282"},{"key":"S0029665126102195_ref35","doi-asserted-by":"publisher","DOI":"10.1016\/j.cmet.2012.06.011"},{"key":"S0029665126102195_ref17","doi-asserted-by":"publisher","DOI":"10.1002\/jpen.1451"},{"key":"S0029665126102195_ref74","first-page":"1152","article-title":"Validity of the malnutrition screening tool as an effective predictor of nutritional risk in oncology outpatients receiving chemotherapy","volume":"14","author":"Isenring","year":"2006","journal-title":"Support Care Cancer"},{"key":"S0029665126102195_ref37","doi-asserted-by":"publisher","DOI":"10.1016\/j.clnu.2018.05.010"},{"key":"S0029665126102195_ref6","first-page":"2625","article-title":"A systematic review of health-related quality of life instruments in patients with cancer cachexia","volume":"21","author":"Wheelwright","year":"2013","journal-title":"Support Care Cancer"},{"key":"S0029665126102195_ref51","doi-asserted-by":"publisher","DOI":"10.1038\/s41392-023-01569-3"},{"key":"S0029665126102195_ref30","doi-asserted-by":"publisher","DOI":"10.1002\/jpen.2688"},{"key":"S0029665126102195_ref63","doi-asserted-by":"publisher","DOI":"10.2196\/resprot.4757"},{"key":"S0029665126102195_ref75","doi-asserted-by":"publisher","DOI":"10.1016\/S0261-5614(03)00098-0"},{"key":"S0029665126102195_ref29","doi-asserted-by":"publisher","DOI":"10.1002\/jpen.2366"},{"key":"S0029665126102195_ref68","doi-asserted-by":"publisher","DOI":"10.48286\/aro.2024.97"},{"key":"S0029665126102195_ref27","doi-asserted-by":"publisher","DOI":"10.1200\/JCO.2014.56.1894"},{"key":"S0029665126102195_ref52","doi-asserted-by":"publisher","DOI":"10.1002\/wsbm.1462"},{"key":"S0029665126102195_ref18","doi-asserted-by":"publisher","DOI":"10.1016\/j.jand.2020.11.007"},{"key":"S0029665126102195_ref42","doi-asserted-by":"publisher","DOI":"10.1017\/S002966511500419X"},{"key":"S0029665126102195_ref21","unstructured":"21.
