Abstract

Background: 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. Methods: 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. Results: 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. Conclusions: 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.
