OBJECTIVE: The purpose of this study was to compare the diagnostic performance of computed tomographic (CT) fluoroscopy-guided percutaneous transthoracic needle aspiration biopsy (NAB) and transbronchial lung biopsy (TBLB) after indeterminate bronchoscopy in patients with suspected malignant pulmonary lesions. METHODS: We included 77 patients who underwent CTF-NAB (n = 53) or TBLB (n = 24) as a second biopsy for pulmonary lesions because of inconclusive pathologic results on initial TBLB. Sensitivity, specificity, and diagnostic accuracy were calculated and compared between the 2 groups using the Fisher exact test. Sensitivity and diagnostic accuracy were also compared according to lesion depth (central vs peripheral), lesion location (upper vs lower), and lesion size (<2 vs 2-3 vs >3 cm). RESULTS: There were 50 (65%) malignant and 27 (35%) benign lesions. The overall sensitivity, specificity, and accuracy for diagnosing pulmonary lesions were 84%, 100%, and 91% for NAB and 50%, 100%, and 63% for TBLB. The sensitivity and accuracy for diagnosing pulmonary lesions were significantly different between the 2 groups (P = 0.019, and P = 0.008). The sensitivity and accuracy of TBLB for diagnosing lesions was significantly different according to the lesion size (P = 0.025, and P = 0.048). CONCLUSION: A second biopsy using CT fluoroscopy-guided NAB is a useful diagnostic modality for exact diagnosis of pulmonary lesions in cases of inconclusive pathologic results on initial TBLB.
