Transthoracic fine-needle aspiration vs concurrent core needle biopsy in diagnosis of intrathoracic lesions: a retrospective comparison of diagnostic accuracy.

摘要: To assess the value and limitations of fine-needle aspiration (FNA) core needle biopsy (CNB) in diagnosis intrathoracic lesions, we retrospectively compared diagnostic accuracy 362 FNA concurrent CNB procedures performed on 350 patients. Based final diagnoses that were determined based combined information from biopsy, resection, clinical, radiologic, microbiologic findings, study cases grouped into 188 malignant, 161 benign, 13 inconclusive lesions. yielded similar for malignant tumors (85.1% vs 86.7%) epithelial neoplasms (86.4% 85.2%), whereas better (96%) than (77%) nonepithelial neoplasms. Combined substantially improved rate malignancy (95.2%). Of benign cases, 50 proven to be benign-specific lesions; provided specific 20 (40%) 46 (92%). The remaining 111 lesions benign-nonspecific findings both specimens. These results indicate should obtained when clinical or radiologic do not match cytologic are considered likely.
