Abstract

Nutritional status is an important factor affecting a patient's clinical outcomes. Early identification of patients who are at risk of malnutrition is important to improve clinical outcomes and reduce health cost. The Malnutrition Universal Screening Tool (MUST) has been recommended as part of the routine nursing assessment for all patients at hospital admission. The aim of this study was to examine the association between nutritional status (MUST), systemic inflammatory response (SIR), body composition, and clinical outcomes in patients undergoing surgery for colorectal cancer. The malnutrition risk was examined using MUST in patients admitted for surgery for colorectal cancer between March 2013 and June 2016. Preoperative computed tomography scans were used to define the body composition. The presence of SIR was evidenced by the modified Glasgow prognostic score and the neutrophil to lymphocyte ratio. Postoperative complications, severity of complication, length of hospital stay, and mortality were considered as outcome measures. The study included 363 patients (199 males, 164 females); 21% of the patients presented with a medium or high nutritional risk. There were significant associations between MUST and subcutaneous adiposity (P < 0.001), visceral obesity (P < 0.001), and low skeletal muscle index (P < 0.001). No statistically significant association was identified between MUST score and presence of any complication or severity of complication. On multivariate analysis, MUST remained independently associated with the length of hospital stay (OR: 2.17; 95% CI: 1.45, 3.26; P < 0.001). Kaplan-Meier survival curves showed an increased number of deaths for patients at medium or high risk of malnutrition (P < 0.001). This association was found to be independent of other confounding factors (HR: 1.45; 95% CI: 1.06, 1.99; P = 0.020). MUST score is an independent marker of risk in those undergoing surgery for colorectal cancer and should remain a key part of preoperative assessment.
