J Urol:老年营养风险指数(GNRI)是否能够预测膀胱癌术后并发症?

2021-12-12 AlexYang MedSci原创

评估了术前GNRI是否与根治性膀胱切除术(RC)后30天的并发症有关。

营养不良在老年人群中普遍存在,并且经常在癌症患者中诊断。在接受根治性膀胱切除术(RC)的患者中,约有三分之一的人营养不良。已证明营养不良会影响接受根治性膀胱切除术患者的短期和长期结果。根治性膀胱切除术是局部非转移性肌层浸润性膀胱癌的标准疗法。然而,尽管手术技术不断进步,RC仍与术后30天39%的总并发症有关。

老年营养风险指数(GNRI)是一个简单的筛选工具,可用于预测老年患者与营养有关的发病和死亡风险

近期,来自美国的研究人员在《J Urol》上发表文章,评估了术前GNRI是否与根治性膀胱切除术(RC)后30天的并发症有关

研究人员使用了美国外科医师学会国家外科质量改进计划数据库中的数据,纳入了2007年至2019年期间,接受膀胱癌治疗的65岁及以上的患者。患者分为有风险(GNRI≤98)或无风险(GNRI>98)组。使用了倾向性得分匹配(PSM)来比较两组之间的基线差异和30天的结果。还使用了多变量逻辑回归分析(MLRA)评估了GNRI作为术后并发症独立预测因素的效果。

研究共确定了2926名符合分析条件的患者,有风险GNRI组有814人(28%),无风险GNRI组有2112人(72%)。研究结果发现,PSM之后,GNRI风险组患者的并发症(P=0.017)、输血(P=0.002)、延长住院时间(LOS)(P=0.004)和非家庭式出院(P<0.001)的比例显著更高。MLRA显示,GNRI降低是死亡率(几率(OR)1.05,95%置信区间(CI):1.01-1.08,p=0.009)、输血(OR 1. 03,95% CI 1.02-1.04,p<0.001),肺炎(OR 1.04,95% CI 1.01-1.07,p=0.013),LOS(OR 1.03,95% CI 1.02-1.05,p<0.001)和非家庭式出院(OR 1.04,95% CI 1.03-1.06,p<0.001)的独立预后因素。

患者选择流程图

综上所述,GNRI是一种标准化的营养状况筛查工具,可用于术前评估接受RC手术老年患者的术后并发症风险,也是死亡率、肺炎、输血、延长住院时间和非家庭出院的独立预测因素。总之,GNRI是一个客观和方便的工具,可直接用于评估接受RC老年膀胱癌患者的营养状况和并发症的风险。
