目的分析食管胃结合部腺癌(adenocarcinoma of the esophagogastric junction,AEJ)患者不同Siewert分型中RBC、NLR及临床特征。方法采用回顾性分析方法收集延安大学附属医院2017年1月1日至2018年12月31日消化内科及胃肠外科进行手术治疗...目的分析食管胃结合部腺癌(adenocarcinoma of the esophagogastric junction,AEJ)患者不同Siewert分型中RBC、NLR及临床特征。方法采用回顾性分析方法收集延安大学附属医院2017年1月1日至2018年12月31日消化内科及胃肠外科进行手术治疗的55例AEJ患者的临床病理资料,分析AEJ患者不同Siewert分型中各项指标及临床特征的变化。结果在不同Siewert分型中,RBC、NLR、肿瘤大小、淋巴结转移比较,差异有统计学意义(P<0.05)。对RBC、NLR、肿瘤大小、淋巴结转移分别进行组内两两比较,发现SiewertⅢ型中RBC值高于SiewertⅡ型,且差异有统计学意义(P<0.05);SiewertⅢ型中NLR值低于SiewertⅡ型,差异有统计学意义(P<0.05);从SiewertⅠ型到SiewertⅢ型,肿瘤的长径逐渐增大且3种Siewert分型相互之间两两比较,差异均有统计学意义(P<0.05);SiewertⅠ型到SiewertⅢ型淋巴结转移率越来越大,差异有统计学意义(P<0.05)。结论不同Siewert分型的AEJ患者具有不同的临床病理特征,SiewertⅢ型与SiewertⅡ型相比RBC水平较高,而NLR却较低;相比于另外两型,SiewertⅢ型肿瘤可能相对较大,淋巴结转移率相对较高,生物学行为可能较差。展开更多
目的探讨白蛋白与纤维蛋白原比值(albumin to fibrinogen ratio,AFR)对食管胃结合部腺癌(adenocarcinoma of esophagogastric junction,AEG)的诊断价值。方法选取2016年1月至2021年12月延安大学附属医院收住的234例AEG患者的临床病理资...目的探讨白蛋白与纤维蛋白原比值(albumin to fibrinogen ratio,AFR)对食管胃结合部腺癌(adenocarcinoma of esophagogastric junction,AEG)的诊断价值。方法选取2016年1月至2021年12月延安大学附属医院收住的234例AEG患者的临床病理资料,另选取同时期健康对照者35名,Kruskal-Wallis H检验AFR与AEG患者临床病理特征的相关性。Logistic回归对AEG危险因素进行分析。采用ROC曲线分析各指标单项及三者联合检测诊断AEG的效能。结果AEG患者AFR显著低于健康对照组,AFR与肿瘤大小、组织学分级、肿瘤分期、淋巴结转移、浸润深度显著相关,与性别、Siewert分型、内镜分型无关。Logistic回归分析显示,AFR、CEA、CA19-9是AEG的独立危险因素。AFR、CEA、CA19-9三者联合检测具有更大的诊断价值(AUC=0.785)。结论AFR、CEA、CA19-9三者联合检测可提高AEG的诊断效能。展开更多
