Mediastinal evaluation in lung cancer

Findings of mediastinal imaging were compared with pathologic findings following thoracotomy and full nodal sampling in 50 patients with bronchogenic carcinoma. All patients underwent full nodal sampling and chest radiography, conventional tomography, CT, and Ga-67 radionuclide scanning. The highest sensitivity for mediastinal metastases noted was 54%, considering nodes greater than or equal to 1.0 cm abnormal at CT. The small size of some involved nodes precluded sensitivity from reaching 100%. Ga-67 scanning did not offer additional information when compared with that of other studies. The predictive value of considering mediastinal lymph nodes greater than or equal to 1.0 cm abnormal at CT was 35%. Reasons for this include reactive nodes proximal to obstruction and prior granulomatous disease. The utility of CT in peripheral T/sub 2/ cancers and central cancers is not clear.
