Abstract：
Nutritional screening and assessment are considered essential steps in nutritional care for cancer patients, malnutrition remains underreported in clinical practice. The aim of this study was to analyse the clinical usefulness of the Patient-Generated Subjective Global Assessment short form (PG-SGA SF©) for nutritional screening in patients with head and neck cancer (HNC). This is a multicentre, cross-sectional study involving patients with HNC. The final score of the PG-SGA SF© was obtained and the nutritional status was diagnosed using the Patient-Generated Subjective Global Assessment (PG-SGA)®, classifying them as well-nourished or malnourished. Receiver operating characteristic curve, ordinal logistic regression, and C-statistic were used. In total, 353 patients with HNC were enrolled and the prevalence of malnutrition, according to the PG-SGA®, was 64.02% and the median final score of PG-SGA SF© was 11 points. The final score of the PG-SGA SF© had high accuracy (area under the curve = 0.915), and scores ≥9 had the best performance in diagnosing malnutrition. PG-SGA SF© final score ≥9 was associated with malnutrition (odds ratio = 28.32, 95% confidence interval= 15.98-50.17), with excellent discriminatory power (C-statistic = 0.872). In conclusion, the PG-SGA SF© demonstrated excellent performance for nutritional screening in patients with HNC. Given that it is a simple instrument that is faster to administer than the PG-SGA®, we recommend its use in clinical practice among such patients.
摘要：
营养筛查和评估被认为是癌症患者营养护理的重要步骤。营养不良在临床实践中仍被低估。这项研究的目的是分析患者生成的主观整体评估简表（PG-SGASF©）用于头颈部癌症（HNC）患者营养筛查的临床实用性。这是一个多中心,涉及HNC患者的横断面研究。获得PG-SGASF©的最终评分，并使用患者生成的主观整体评估（PG-SGA）®诊断营养状况。将它们分类为营养良好或营养不良。接收机工作特性曲线,有序逻辑回归，使用C统计量。总的来说,共纳入353例HNC患者，营养不良患病率，根据PG-SGA®，为64.02%，PG-SGASF©的中位最终得分为11分。PG-SGASF©的最终得分具有很高的准确性（曲线下面积=0.915），评分≥9分在诊断营养不良方面表现最好.PG-SGASF©最终得分≥9与营养不良相关（比值比=28.32，95％置信区间=15.98-50.17），具有良好的鉴别力(C统计量=0.872)。总之,PG-SGASF©在HNC患者的营养筛查中表现优异。鉴于它是一种简单的仪器，比PG-SGA®管理起来更快，我们建议在此类患者的临床实践中使用它。
