AbstractBackground & ObjectivesLow muscle mass, measured using computed tomography (CT), is associated with poor surgical outcomes. We aimed to include CT‐muscle mass in malnutrition diagnosis using the Global Leadership Initiative on Malnutrition (GLIM) criteria, compare it to the International Classification of Diseases 10th Revision (ICD‐10) criteria, and assess the impact on postoperative outcomes after oesophagogastric (OG) cancer surgery.MethodsOne hundred and eight patients who underwent radical OG cancer surgery and had preoperative abdominal CT imaging were included. GLIM and ICD‐10 malnutrition data were assessed against complication and survival outcomes. Low CT‐muscle mass was determined using predefined cut‐points.ResultsGLIM‐defined malnutrition prevalence was significantly higher than ICD‐10‐malnutrition (72.2% vs. 40.7%, p < 0.001). Of the 78 patients with GLIM‐defined malnutrition, low muscle mass (84.6%) was the predominant phenotypic criterion. GLIM‐defined malnutrition was associated with pneumonia (26.9% vs. 6.7%, p = 0.010) and pleural effusions (12.8% vs. 0%, p = 0.029). Postoperative complications did not correlate with ICD‐10 malnutrition. Severe GLIM (HR: 2.51, p = 0.014) and ICD‐10 (HR: 2.15, p = 0.039) malnutrition were independently associated with poorer 5‐year survival.ConclusionsGLIM criteria appear to identify more malnourished patients and more closely relate to surgical risk than ICD‐10 malnutrition, likely due to incorporating objective muscle mass assessment.
