Forty-two patients with T2 bronchogenic carcinoma were evaluated with plain radiography, conventional 55/sup 0/ oblique hilar and anteroposterior mediastinal tomography, and computed tomography (CT) to compare their accuracy in assessing mediastinal and hilar nodal metastases. Definitive staging was achieved by thoracotomy and histopathological evaluation of resected specimens. All modalities demonstrated about the same accuracy, however, in the 25 patients with hilar and/or mediastinal lymphadenopathy, CT of the mediastinum was more sensitive but not more specific than the other two and conventional tomography was no more accurate than CT for hilar evaluation. Overall, no technicue was accurate enough for routine staging; their value may lie in directing biopsy or in treatment planning in patients with inoperable disease.
