    Abstract:
    The diagnostic potential of secondary transthoracic needle biopsy (TNB) following negative fiberoptic bronchoscopy in patients with peripheral circumscribed pulmonary lesions was evaluated in a retrospective study. The records from 224 patients who had TNB performed over a five-year period were reviewed. Of these, 103 patients met the criteria for inclusion in this series. The overall diagnostic yield of TNB in malignancy was 73.8% (54 of 73 patients). TNB allowed cytological classification of the tumour type in 72.2% (39 of 54 patients). Five of the 54 patients (9.3%) presented with small cell anaplastic bronchogenic carcinoma, diagnosed by TNB, and were treated with chemotherapy. Of the 49 patients with a negative TNB, 27 went on to diagnostic surgical procedures; 19 had malignancy, three benign tumour, two infection, and three sequelae after pulmonary infarction. The remaining 22 patients with undiagnosed lesions were followed long term, five showed progression of the pulmonary lesion suggesting malignancy. TNB appeared unsuitable in the diagnosis of benign lesions. Unspecific inflammation was not considered evidence of benignity, and therefore a definitive benign diagnosis was not made by TNB in this series. There were no serious complications to TNB. In 18.1% of the procedures a pneumothorax developed, indicating a chest tube in 8.6% of the procedures. TNB is a suitable diagnostic procedure with a high diagnostic yield in patients with peripheral, malignant pulmonary lesions.
