Patient-generated subjective global assessment versus nutritional risk screening 2002 for gastric cancer in Chinese patients

Abstract

Aim: Patient-Generated Subjective Global Assessment (PG-SGA) and Nutritional Risk Screening 2002 (NRS2002) are used to evaluate patients’ nutritional status. Materials & methods: The data of 114 gastric cancer patients with pyloric obstruction treated between July 2016 and July 2017 were assessed retrospectively. Results: Based on clinical evaluation, 70.1% had malnutrition, with 61.4% at nutritional risk by NRS2002 and 66.7% by PG-SGA. The area under the receiver operating characteristic curve was 0.858 for PG-SGA and 0.706 for NRS2002. Sensitivity and specificity were 89 and 85% for PG-SGA and 78 and 76% for NRS2002. In both assessments, patients at risk showed more postoperative complications. Conclusion: PG-SGA was more suitable for evaluating the preoperative nutritional status of gastric cancer patients with pyloric obstruction, with higher diagnostic efficacy.
