纵隔镜与EBUS-TBNA对肺癌诊断和分期价值的比较研究

A Comparative Study on the Diagnosis and Staging of Lung Cancer between Mediastinoscopy and EBUS-TBNA

背景与目的支气管镜超声引导针吸活检术(endobronchial ultrasound-guided transbronchial needle aspira-tion,EBUS-TBNA)逐渐普及,但其对肺癌的术前分期和纵隔肿物的诊断价值尚待探讨。本研究拟对比研究EBUS-TBNA和纵隔镜的诊断效能,期望为理性的选择应用提供客观依据。方法收集2009年7月-2012年12月纵隔镜检查术患者361例,其中肺癌199例,纵隔肿物162例;EBUS-TBNA患者348例,其中肺癌216例,纵隔肿物132例。比较两种方法的诊断结果和相关指标,分析二者对肺癌术前分期和纵隔肿物诊断的临床应用价值。结果以石蜡病理学诊断为金标准,纵隔镜检查术的诊断准确性为98.33%,敏感性98.17%,特异性100%;EBUS-TBNA的准确性为90.80%,敏感性90.00%,特异性100%。两者对肺癌的诊断和分期效能无明显差异(P>0.05),纵隔镜对纵隔肿物的诊断效能较高(P<0.05)。结论纵隔镜和EBUS-TBNA对肺癌具有相似的的术前诊断和分期作用,但对纵隔肿物的诊断效能则以纵隔镜检查术为高。

Background and objective Endobronchial ultrasound-guided transbronchial needle aspiration（EBUS-TBNA） has been gradually universal application, but its value in the preoperative staging of lung cancer and mediastinal mass biopsy remains to be explored. The aim of this study is to evaluate the value of clinical application between mediastinoscopy and EBUS-TBNA, desiring to provide an objective basis for the rational choice applications. Methods Between July 2009 and December 2012, mediastinoscopy patients with 361 cases accepted biopsy, including 199 cases of lung cancer and 162 cases of mediastinal mass of unknown origin, EBUS-TBNA patients with 348 cases accepted biopsy, including 216 cases of lung cancer and 132 cases of mediastinal mass. Comparing the diagnostic results and related indicators of two methods, this article analyzed the clinical value both the preoperative staging of lung cancer and the diagnosis of mediastinal mass. Results Taking pathology diagnosis as the gold standard, the accuracy, sensitivity and specificity of mediastinoscopy and EBUS-TBNA are 98.33%, 98.17%, 100% and 90.80%, 90.00%, 100%. Two techniques in the diagnosis and staging of lung cancer have not statistically significant （P〈0.05）, but in the diagnosis of mediastinal mass have statistical significance （P〈0.05）. Conclusion Mediastinoscopy and EBUS-TBNA have a similar role in the diagnosis and staging of lung cancer; but mediastinoscopy for mediastinal mass is superior to EBUS-TBNA.
