[Computer tomography for staging of bronchial carcinomas (author's transl)].

Thoracic computer tomography was performed in 135 patients with bronchial carcinoma. 1) In 90% a precise estimate of the extent of the primary tumour was possible. The computer tomogram was markedly superior to traditional radiological methods in showing invasion of the chest wall and mediastinum. 2) Regional lymph node metastases were demonstrated correctly in 82%. Lymph node enlargement must be differentiated from that due to benign causes. 3) In 92%, the extent of distal metastases could be correctly established. The computer tomogram makes it possible to avoid exploratory thoracotomy if there is transpleural invasion, extensive mediastinal lymph node metastasation or distant metastasation. Where there is doubt, computer tomography-guided needle aspiration should be employed.
