Massive lymphadenopathy and direct mediastinal invasion are well-recognized phenomena in patients with small cell lung cancer (SCLC). The aim of this study was to assess the utility of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) in the diagnosis of SCLC.
We retrospectively reviewed the records of 780 patients who underwent EBUS-TBNA at our institution from March 2004 to June 2012. Of these, 101 had a final diagnosis of SCLC. Excluding 3 patients with known SCLC who underwent EBUS-TBNA for staging purposes and including 2 patients who underwent EBUS-TBNA twice for the diagnosis of recurrence after achieving complete response by chemoradiation therapy during the study period, a total of 100 EBUS-TBNA procedures in 98 patients were analyzed.
Other diagnostic tests prior to the initial EBUS-TBNA had failed to yield a diagnosis in 41 patients. The overall diagnostic yield of EBUS-TBNA for SCLC was 97% (97 of 100). Rapid on-site cytologic evaluation (ROSE) was performed at the operator's discretion in 77 procedures. ROSE did not have any impact on diagnostic yield (99% with ROSE vs. 90% without ROSE, p=0.1), but the use of ROSE was associated with fewer lesions (mean 1.1 with ROSE vs. 1.6 without ROSE, p<0.01) or aspirates (mean 2.3 with ROSE vs. 4.0 without ROSE, p<0.01).
EBUS-TBNA provided a high diagnostic yield in SCLC with or without ROSE. EBUS-TBNA can be recommended for patients suspected to have SCLC, even if other diagnostic tests have failed.
小细胞肺癌(SCLC)患者出现大量淋巴结肿大和纵隔直接侵犯是公认的现象。本研究的目的是评估支气管内超声引导下经支气管针吸活检术(EBUS-TBNA)在SCLC诊断中的效用。
我们回顾性分析了2004年3月至2012年6月在本机构接受EBUS-TBNA的780例患者的记录。其中,101例最终诊断为SCLC。排除3例已知SCLC且因分期目的接受EBUS-TBNA的患者,并纳入2例在研究期间经放化疗达到完全缓解后因诊断复发而接受两次EBUS-TBNA的患者,共分析了98例患者的100次EBUS-TBNA操作。
在最初的EBUS-TBNA之前,其他诊断测试未能在41例患者中得出诊断结果。EBUS-TBNA对SCLC的总体诊断率为97%(100例中的97例)。77例操作中,根据操作者的判断进行了快速现场细胞学评估(ROSE)。ROSE对诊断率没有任何影响(有ROSE时为99%,无ROSE时为90%,p = 0.1),但使用ROSE时病变(有ROSE时平均为1.1个,无ROSE时为1.6个,p < 0.01)或抽吸物(有ROSE时平均为2.3次,无ROSE时为4.0次,p < 0.01)较少。
无论有无ROSE,EBUS-TBNA在SCLC中都具有较高的诊断率。即使其他诊断测试失败,对于疑似SCLC的患者也可推荐使用EBUS-TBNA。
