Abstract
Computed tomography (CT) examinations of the brain, liver and upper abdomen were obtained in 60 previously untreated patients with histologically proven small cell carcinoma of the lung (SCCL). These results, together with clinical findings and laboratory investigations including radionuclide scans, determined the final staging of the patients. CT changed the stage from limited to extensive disease in 3 patients and from extensive to limited disease in seven patients. Overall, 10 of 60 patients (16%) had their final stage altered by CT. CT examinations may yield valuable information in some cases of small cell lung cancer but it is of limited value in the routine staging of these patients.
