The primary aim of the study was to compare two nutritional status evaluation tools: the Patient-Generated Subjective Global Assessment (PG-SGA) and Nutritional Risk Screening (NRS-2002). Using the European Organization for Research and Treatment of Cancer Quality of Life Core Questionnaire 30 (EORTC QLQ-C30), the second aim was to provide constructive advice regarding the quality of life of patients with malignancy.
This study enrolled 312 oncology patients and assessed their nutritional status and quality of life using the PG-SGA, NRS-2002, and EORTC QLQ-C30.
The data indicate that 6% of the cancer patients were well nourished. The SGA-A had a higher sensitivity (93.73%) but a poorer specificity (2.30%) than the NRS-2002 (69.30% and 25.00%, respectively) after comparison with albumin. There was a low negative correlation and a high similarity between the PG-SGA and NRS-2002 for evaluating nutritional status, and there was a significant difference in the median PG-SGA scores for each of the SGA classifications (P < 0.001). The SGA-C group showed the highest PG-SGA scores and lowest body mass index. The majority of the target population received 2 points for each item in our 11-item questionnaire from the EORTC QLQ-C30.
The data indicate that the PG-SGA is more useful and suitable for evaluating nutritional status than the NRS-2002. Additionally, early nutrition monitoring can prevent malnutrition and improve the quality of life of cancer patients.
本研究的主要目的是比较两种营养状况评估工具：患者主观整体评估（PG-SGA）和营养风险筛查（NRS-2002）。使用欧洲癌症研究与治疗组织生活质量核心问卷 30 项（EORTC QLQ-C30），第二个目的是就恶性肿瘤患者的生活质量提供建设性意见。
本研究纳入 312 名肿瘤患者，使用 PG-SGA、NRS-2002 和 EORTC QLQ-C30 评估其营养状况和生活质量。
数据显示，6%的癌症患者营养状况良好。SGA-A 的敏感性（93.73%）高于 NRS-2002（69.30%），但特异性（2.30%）低于 NRS-2002（25.00%），与白蛋白相比。PG-SGA 和 NRS-2002 评估营养状况的相关性较低，相似性较高，SGA 各分类的 PG-SGA 评分中位数存在显著差异（P < 0.001）。SGA-C 组的 PG-SGA 评分最高，体重指数最低。EORTC QLQ-C30 的 11 项问卷中，目标人群的大部分项目得分为 2 分。
数据表明，PG-SGA 比 NRS-2002 更有用、更适合评估营养状况。此外，早期营养监测可以预防营养不良，提高癌症患者的生活质量。
