Abstract

In cases of pleural lesion, tissue samples can be obtained through thoracoscopy or closed needle biopsy for histopathological analysis. Cutting needle biopsy is a relatively recent addition to these techniques. The aim of this study was to evaluate the diagnostic accuracy and safety of computed tomography‑guided cutting needle pleural biopsy (CT‑CNPB), as well as the associated complications, in patients with pleural lesion. This study was a retrospective analysis of 92 percutaneous CT‑CNPBs on 90 patients between March 2008 and May 2013. For group comparisons, χ2 tests were used to detect the risk factors for diagnostic accuracy (false‑negative rate). Of the 92 CT‑CNPBs, malignant lesions were diagnosed in 55 cases (mesothelioma in 12, metastatic pleural disease in 36, synoviosarcoma in one, indeterminate‑origin disease in one and false‑negative lesion in five) and benign pleural disease was diagnosed in 37 cases (inflammation in 15, tuberculosis in 10, granuloma in three, solitary fibrous tumor in two, hematoma in one, fungus in one and indeterminate‑origin disease in five). The sensitivity of diagnostic malignant lesion was 90.9%, and the specificity and positive and negative predictive values were 100, 100 and 88.1%, respectively. The overall diagnostic accuracy was 94.6%. A specific diagnosis was achieved in 89.1% of malignant lesions and 86.4% of benign lesions. Univariate analysis of the risk factors affecting accuracy (false‑negative rate) did not reveal any significant differences (all P>0.05). The complication rates were 6.5% for pneumothorax, 8.7% for hemorrhage and 1.1% for hemothorax. In conclusion, CT‑CNPB is a safe and accurate diagnostic technique that can be recommended as the primary method of diagnosis in patients with pleural thickening or lesions observed by CT scan.
