Abstract

背景与目的纤维支气管镜腔内超声引导针吸活检术(endobronchial ultrasound guided transbronchial needle aspiration, EBUS-TBNA)作为近年来发展的新技术,具有操作简单、创伤小、准确率和安全性高及可重复性等优点,已成为进行肺癌诊断和纵隔分期的新标准。由于小细胞肺癌(small cell lung cancer, SCLC)和非小细胞肺癌(non-small cell lung cancer, NSCLC)的生物学特性以及治疗方案的不同,因此,在早期能诊断并鉴别的病理类型,对于肺癌的分期、治疗及预后均有很重要意义。本文探讨EBUS-TBNA在诊断SCLC和NSCLC中的准确率及敏感性。方法回顾性分析2012年1月-2018年12月首都医科大学宣武医院胸外科进行142例经支气管内超声引导针吸活检术患者的临床资料,选取最终确诊85例SCLC和NSCLC患者,比较两组差异。结果最终经免疫组化病理明确SCLC 45例,其中经EBUS-TBNA明确诊断为SCLC 42例,诊断准确率、敏感度分别为93.3%(42/45)、100.0%(42/42)。经细胞学检查明确诊断22例,诊断准确率为48.9%(22/45);经病理明确诊断NSCLC 40例,其中经EBUS-TBNA明确诊断为NSCLC 35例,诊断准确率、敏感度分别为87.5%(35/40)、100.0%(35/35)。经细胞学检查明确诊断11例,诊断准确率为27.5%(11/40);EBUS-TBNA在SCLC组的诊断准确率明显高于NSCLC组,且有统计学意义(P < 0.05)。结论EBUS-TBNA用于诊断SCLC较NSCLC的准确率高。EBUS-TBNA作为微创技术,可协助SCLC早期诊断,及时治疗。
