OBJECTIVE: To retrospectively investigate and compare the usefulness of transthoracic fine needle aspiration (FNA), core biopsy and a combination of the two in the diagnosis of pulmonary lesions.
STUDY DESIGN: Two hundred ninety-six patients who had undergone FNA, core biopsy or both for lung lesions were divided into malignant and benign groups according to the final diagnoses, which were based on the cytologic and histopathologic findings combined with clinical features. In each group, the diagnostic usefulness of FNA, core biopsy and a combination of the two were evaluated by comparing the results of each with the final diagnoses.
RESULTS: In the malignant group, FNA was diagnostically helpful in 188 of 205 patients (91.7%) and core biopsy in 158 of 180 patients (87.8%). The combination of the two methods improved the result to 172 of 178 patients (96.6%). The sensitivities were 94.6%, 88.3% and 97.2%, respectively, for each result. In the benign group, 71.1% (64/90), 70.1% (47/67) and 74.2% (49/66) of cases received specific or nonspecific diagnoses by FNA, core biopsy and their combination, respectively. The rates of specific diagnoses were 20.1%, 21.0% and 31.8%, respectively.
CONCLUSION: The combination of FNA and core biopsy markedly improved the diagnostic yields in the malignant group and, to a lesser degree, also in the benign group.
