OBJECTIVE: Computed tomography has recently been proposed as a useful method for the early detection of @entity2 . In this study we compared the stage distribution of @entity2 detected by a computed tomographic scan with that of @entity2 detected by a routine chest x-ray film. METHODS: Two groups of @entity1 with biopsy-proven @entity1149 were reviewed. In the first group of 32 @entity1 , the @entity5 were detected by a computed tomographic scan. In a second group (n = 101), the @entity2 were detected on routine chest x-ray films. @entity1 with @entity358 or a history of @entity5 were excluded. RESULTS: There was no difference in age, sex, or cell-type distribution between the 2 groups. A significantly greater number of @entity1 undergoing a computed tomographic scan had stage IA disease compared with those having an x-ray film. Of the 32 @entity1 in the group having a scan, 10 had @entity5 1 cm or less in size versus 6 of 101 in the group having a chest radiograph. Additionally, there was a significant reduction in advanced stage disease in the group having a scan. CONCLUSIONS: In this retrospective study, a higher incidence of @entity5 and significantly fewer cases of more advanced disease were observed in @entity1 screened with computed tomography than in those having a chest radiograph. These data suggest that computed tomographic screening may be of value in improving the survival of @entity1 with @entity1149 .
