Diagnostic Consistency of GLIM and PG-SGA for Malnutrition in Pancreatic Cancer

Malnutrition was diagnosed according to the GLIM consensus criteria. This required at least one phenotypic criterion (non-volitional weight loss, low BMI, or reduced muscle mass) and one etiologic criterion (reduced food intake/assimilation or inflammation/disease burden). Reduced muscle mass was assessed by bioelectrical impedance analysis (BIA). The assessment was performed once for each patient within 24 hours of hospital admission.

A comprehensive nutritional assessment administered by trained clinical staff. The tool comprises patient-reported sections (weight history, food intake, symptoms, activities/function) and clinician-assessed sections (disease, metabolic demand, physical exam). For this study, a total score of ≥2 was considered indicative of malnutrition. The assessment was performed once for each patient within 24 hours of hospital admission.
