Bronchoscopic tissue forceps biopsy (BBX) is a standard procedure for diagnosis of malignancy in the lung. Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) has proven to be a sensitive alternative to tissue biopsy for the diagnosis and staging of lung tumors. We report our institutional experience with diagnostic yield when combining BBX and EBUS-TBNA in the bronchoscopic evaluation of patients presenting with lung lesion(s). The pathology files at our institution were searched for all patients who underwent combined BBX and EBUS-TBNA procedures between 1/09 and 6/10 for the diagnosis of malignancy. The data points included biopsy site, cytologic, and histopathologic diagnoses and follow-up. We identified 115 patients who underwent BBX combined with EBUS-TBNA. About 107 (93%) of the patients received a definitive pathologic diagnosis; 93 (81%) were malignant. BBX and EBUS-TBNA of the lung lesion only were performed in 21 patients, BBX and EBUS-TBNA of lymph node(s) only in 78 patients with BBX and a combination of EBUS-TBNA of the lung lesion and lymph node(s) in 16 patients. Immunostains were performed for 71 (76%) patients and molecular testing for 11 (12%) patients. Diagnostic yield is increased when bronchoscopic technologies are combined. In a significant number of patients where BBX was negative, EBUS-TBNA provided diagnostic material, increasing diagnostic yield by 18%. In a subset of these patients the EBUS-TBNA assisted in the staging of a primary tumor. By combining these procedures, more tissue was obtained for immunohistochemistry and molecular testing, which facilitated personalized management in a minimally invasive manner.
