Endobronchial ultrasound (EBUS) transbronchial needle aspiration (TBNA) has a high diagnostic yield when evaluating mediastinal and hilar lymphadenopathy (LAD). Having previously demonstrated the safety of EBUS-guided cautery-assisted transbronchial nodal forceps biopsy (ca-TBFB), we report disease-specific improvements in diagnostic yield and tissue acquisition when supplementing the EBUS-TBNA-based standard of care (SOC) with ca-TBFB.
We retrospectively reviewed 213 patients who sequentially underwent SOC and ca-TBFB during the same procedure. We determined 3 clinical scenarios of interest based on preprocedural imaging: isolated mediastinal/hilar LAD, LAD associated with a nodule or mass suspicious for malignancy, and LAD associated with parenchymal findings suggestive of sarcoidosis. Using validated methods, we assessed diagnostic yield on a per-patient basis and specimen quality on a per-node basis on the 136 patients meeting diagnostic criteria.
Administration of disease-specific SOC with ca-TBFB yielded gains that varied by diagnosis. Diagnostic yields of SOC and its supplementation with ca-TBFB were 91.8% and 93.4% (P = .50) of the 61 patients diagnosed with solid-organ malignancy, 62.7% and 94.9% (P < .001) of the 59 patients diagnosed with sarcoidosis, and 62.5% and 93.8% (P = .042) of the 16 patients diagnosed with lymphoma, the. For each disease process, specimens obtained with ca-TBFB exhibited statistically higher quality.
We suggest that relative to SOC, ca-TBFB improves diagnostic yield for sarcoidosis and lymphoma while providing uniformly better tissue quality and cellularity. We propose a protocol for use of this innovative technique.
支气管内超声(EBUS)经支气管针吸活检(TBNA)在评估纵隔和肺门淋巴结病(LAD)时具有较高的诊断率。我们之前已经证明了 EBUS 引导下电灼辅助经支气管淋巴结活检钳(ca-TBFB)的安全性,我们报告了当在 EBUS-TBNA 为基础的标准治疗(SOC)的基础上补充 ca-TBFB 时,诊断率和组织采集的疾病特异性改善。
我们回顾性分析了 213 例在同一程序中先后接受 SOC 和 ca-TBFB 的患者。我们根据术前影像学确定了 3 种感兴趣的临床情况:孤立性纵隔/肺门 LAD、LAD 伴可疑恶性的结节或肿块、LAD 伴提示结节病的实质发现。使用验证方法,我们根据符合诊断标准的 136 例患者,在每位患者的基础上评估诊断率,在每个节点的基础上评估标本质量。
根据疾病特异性 SOC 进行治疗,并结合 ca-TBFB,诊断率因诊断而异。SOC 和 SOC 联合 ca-TBFB 的诊断率分别为 61 例实体器官恶性肿瘤患者的 91.8%和 93.4%(P=0.50),59 例结节病患者的 62.7%和 94.9%(P<0.001),16 例淋巴瘤患者的 62.5%和 93.8%(P=0.042)。对于每种疾病过程,ca-TBFB 获得的标本质量均较高。
我们认为,与 SOC 相比,ca-TBFB 提高了结节病和淋巴瘤的诊断率,同时提供了更均匀的组织质量和细胞性。我们提出了一种使用这种创新技术的方案。
