Chest:超声内镜在肺癌肿瘤辅助疗法后纵膈再分期中的作用

2018-04-21 xiangting MedSci原创

超声内镜检查在肺癌的纵膈再分期中是安全的,并具有高度特异性。

肺癌肿瘤辅助疗法后纵隔再分期的最佳方式仍不清楚。目前手术方法被认为是参考标准。这项研究评估了超声内镜技术在肺癌的纵膈再分期中的作用。

对PubMed和EmBase数据库进行系统检索,以查找III期肺癌诱导治疗后利用内镜超声(EUS)、支气管内超声(EBUS)或两者组合(CUS)进行纵膈再分期的研究。纳入研究的质量使用QUADAS-2工具进行评估。通过计算每项研究的敏感性、特异性、似然比(LR)和诊断优势比(DOR)分析内镜超声的准确性,并使用双因素模型汇总结果。评估了异质性和发表偏倚。通过敏感性分析和meta回归探讨了异质性的潜在原因。

纳入10项研究(n = 574)。合并的敏感性、特异性、DOR、阳性和阴性LRs分别为67%(95%置信区间[CI],56-77),99%(95%CI,89-100),157,52.0和0.33。没有报道并发症。敏感性结果存在显著异质性。敏感性分析确定了影响异质性的几个因素,其中包括研究设计、偏倚风险等。超声内镜检查的敏感性也与Meta回归中的N2疾病的患病率有关。漏斗图证明存在发表偏倚,但在统计检验中并不明显。

超声内镜检查在肺癌的纵膈再分期中是安全的,并具有高度特异性。
