Different nutritional assessment tools as predictors of postoperative complications in patients undergoing colorectal cancer resection

摘要

Background & aims: Malnutrition in patients with colorectal cancer contributes to increased postoperative complications. The aim of the study was to evaluate the prognostic value of several nutritional assessment parameters: body mass index versus percentage of weight loss grading system (BMI/%WL); Patient-Generated Subjective Global Assessment (PG-SGA); standardized phase angle (SPA) by BIA; muscle strength by handgrip strength; muscle mass by computerized tomography; and the combination of muscle mass and strength in patients undergoing resection surgery.
