J Thorac Dis:c-TBNA和EBUS-TBNA在肺癌诊断检出率上无显著差异

2014-07-21 jennifer_jjy 丁香园

经支气管针吸活检术(TBNA)已问世超过30年,可从胸部淋巴结获取组织和细胞学标本,诊断敏感性接近80-90%。最近部分专家指出超声内镜引导下的经支气管针吸活检术(EBUS-TBNA)诊断敏感性更高。但EBUS-TBNA操作复杂,对操作者需额外培训,患者耐受度差,比传统TBNA(c-TBNA)花费更多。中国苏州大学第一附属医院及美国约翰霍普金斯大学学者进行了一项研究,提示c-TBNA和EBUS-T

经支气管针吸活检术(TBNA)已问世超过30年,可从胸部淋巴结获取组织和细胞学标本,诊断敏感性接近80-90%。最近部分专家指出超声内镜引导下的经支气管针吸活检术(EBUS-TBNA)诊断敏感性更高。但EBUS-TBNA操作复杂,对操作者需额外培训,患者耐受度差,比传统TBNA(c-TBNA)花费更多。

中国苏州大学第一附属医院及美国约翰霍普金斯大学学者进行了一项研究,提示c-TBNA和EBUS-TBNA在肺癌诊断检出率及分期准确率上无显著差异。文章最近发表在J Thorac Dis杂志上。

该前瞻对照研究共纳入了287名有纵隔及肺门淋巴结肿大患者,这些患者需通过TBNA以明确肺癌诊断及分期。研究从2006年11月27日开始到2013年4月26日结束。所有患者在目标淋巴结区域行同等次数(每个淋巴结穿刺1-3次)的c-TBNA和EBUS-TBNA操作,c-TBNA先于EBUS-TBNA进行。穿刺涂片及标本通过细胞学筛查和免疫组化分子生物标记进行病理诊断。

研究结果显示,有253名患者取得了至少一组的c-TBNA和EBUS-TBNA标本。83名患者诊断为恶性肿瘤。其中经c-TBNA确诊64例,经EBUS-TBNA确诊62例。c-TBNA和EBUS-TBNA同时确诊的有50例。对这83名患者,c-EBUS和EBUS-TBNA在肿瘤检出率上无显著性差异。但在肿瘤穿刺阳性率上c-TBNA和EBUS-TBNA有显著差异,EBUS-TBNA明显优于c-TBNA。

上述结果显示,c-TBNA和EBUS-TBNA在肺癌诊断检出率及分期准确率上无显著差异。临床实践中选择应用何种TBNA,应充分考虑操作者TBNA(c-TBNA或EBUS-TBNA)的掌握熟练程度及患者病情后权衡利弊后加以个体化应用。
