Percutaneous needle aspiration biopsies were done in 57 patients with suspected chest tumor. All cases were aspirated with a modified Menghini aspiration biopsy set under the guidance of fluoroscopy (53 cases) and ultrasonography (4 cases). Forty-seven cases (82.5%) were proved by pathologic or cytologic examinations, 5 cases (8.8%) were proved by exploratory thoracotomy and the other 5 cases (8.8%) were unable to be proved due to loss of follow-up. Excluding the 5 cases that were unable to be proved, there were 17 benign tumors (32.7%) and 35 malignant tumors (67.3%). From pathologic specimens, the diagnostic rate of percutaneous needle aspiration biopsy was 76.5% (13/17) in benign chest tumors and 74.3%) (26/35) in malignant chest tumors; by cytologic specimen, the diagnostic rate in benign chest tumor was 0% (0/17) and in malignant chest tumor was 88.6% (31/35). No matter whether by pathologic or cytologic specimen, the diagnostic rate of benign chest tumor was 76.5% (13/17) and that of the malignant chest tumor was 97.1% (34/35). Pneumothorax was found in 7 cases (12.3%) and hemoptysis was also seen in 12.3% (7/57). No particular management was needed except chest tube insertion and drainage in 2 pneumothorax cases. Percutaneous needle aspiration biopsy is a safe, simple, reliable and direct method for establishing a diagnosis in patients with suspected chest tumor.
