Abstract：
OBJECTIVE: Nutrition impact symptoms (NIS) are associated with weight loss (WL), and decreased energy intake in cross-sectional studies. We aimed to ascertain associations between changes in NIS burden, energy intake and WL over time in patients with advanced cancer.
METHODS: Adult patients from an observational radiotherapy study for painful bone metastases self-reported NIS and WL using the Patient-Generated Subjective Global Assessment tool (PG-SGA) at baseline and week eight (W8). NIS burden, the sum of NIS per patient, categorised as 0, 1-2 and ≥3 with changes defined as 2-point differences from baseline to W8 were used. Energy intake was assessed by 24-hour recall interviews.
RESULTS: 111 patients (72.1%) were analysed and grouped by NIS burden; 0 NIS (44.1%), 1-2 NIS (30.6%) and ≥3 NIS (25.2%). Patients with NIS burden of ≥3 reported higher baseline WL compared with those with 1-2 or 0 NIS (46.4% vs 18.2% vs 10.2%, respectively, p=0.002). At W8, 21 patients (19%) reported improved NIS burden, accompanied by a lower proportion of severe (≥5%) new-onset WL (19% vs 42.1%) and higher energy intake (median 29.6 vs 21.2 kcal/kg) than those with worsened NIS burden (17.1%).
CONCLUSIONS: NIS management may improve energy intake and prevent WL, emphasising the importance of systematic follow-up and interventions.

摘要：
目的：营养影响症状（NIS）与体重减轻（WL）有关，横断面研究中的能量摄入减少。我们的目标是确定NIS负担变化之间的关联，晚期癌症患者的能量摄入和WL随时间的变化。
方法：在基线和第8周（W8）使用患者生成的主观整体评估工具（PG-SGA），对疼痛性骨转移进行观察性放疗研究的成年患者自我报告NIS和WL。NIS负担，每位患者的NIS总和，使用分类为0,1-2和≥3的变化定义为从基线到W8的2点差异.通过24小时召回访谈评估能量摄入。
结果：111例患者（72.1％）进行了分析，并按NIS负荷进行了分组；0NIS（44.1％），1-2NIS（30.6%）和≥3NIS（25.2%）。NIS负荷≥3的患者报告的基线WL高于NIS1-2或0的患者（46.4％vs18.2％vs10.2％，分别,p=0.002)。在W8，21名患者（19%）报告NIS负担改善，与NIS负担恶化的患者(17.1%)相比,严重(≥5%)新发WL的比例(19%vs42.1%)和较高的能量摄入(中位数29.6vs21.2kcal/kg)。
结论：NIS管理可以改善能量摄入并预防WL，强调有系统的后续行动和干预措施的重要性。
