文摘目的探讨血清尿酸/白蛋白比值(Uric acid/albumin ratio,UAR)与结直肠癌术后患者的预后有无相关性。方法收集2018年9月~2021年9月于我院行根治性结直肠癌手术患者206例的资料,分为存活组(n=188)和死亡组(n=18),比较两组患者临床资料。采用单因素Logistic及多因素分析影响结直肠癌患者术后3年死亡的因素。使用受试者工作特征(Receiver operating characteristic curve,ROC)曲线计算曲线下面积(Area under the curve,AUC),比较术前尿酸、白蛋白、术前与术后UAR对结直肠癌术后患者预后的预测效能。结果多因素分析结果显示,术前UAR(OR=1.82,95%CI:1.16~2.87,P=0.010)、术后UAR(OR=1.25,95%CI:1.05~1.49,P=0.013)是影响结直肠癌术后患者预后的独立危险因素。ROC曲线分析结果显示,术前UAR预测结直肠癌术后患者术后3年死亡的AUC为0.831(95%CI:0.714~0.948);敏感度为72.20%,特异度为90.40%。术后UAR预测患者术后3年死亡的AUC为0.759(95%CI:0.602~0.915);敏感度为66.70%,特异度为97.30%。高UAR组预测术后3年死亡的AUC为0.838(95%CI:0.726~0.951),敏感度为92.90%,特异度为67.30%。低UAR组预测术后3年死亡的AUC为0.571(95%CI:0.319~0.824),敏感度为75.00%,特异度为57.90%。结论术前UAR是预测结直肠癌术后患者预后的独立危险因素。术前高UAR患者预后较差,高UAR对结直肠癌术后患者预后3年死亡风险有一定的预测价值。
