BACKGROUND: Postoperative mortality rates have been published in relation to operative procedure or preexisting @entity358 . We analyzed our @entity1 for the effect of the @entity86 stage on perioperative mortality. @entity1 AND METHODS: Retrospective study of all thoracotomies for resections ( n=1281) in primary @entity2 from January 1987 to December 1997. Uni- and multivariate analysis was performed for operative procedure, mortality (30 and 90 days), @entity5 stage, sex, age, @entity5 localization, and completeness of resection. Radical resection was achieved in 91.9% of the @entity1 . RESULTS: Overall postoperative deaths occurred in 4% and 7.3% of @entity1 after 30 and 90 days respectively. Depending on the operative procedure the mortality after segmental resection ( n=116) was 0.9% and 1.7%, lobectomy ( n=621) 3.0% and 5.7%, sleeve lobectomy ( n=152) 5.3% and 7.9%, and pneumonectomy ( n=314) 6.7% and 12.5%, respectively. Within 30 and 90 days postoperatively deaths occurred, respectively, in 0.8% and 1.0% of stage I @entity1 ( n=493), 5.4% and 5.4% of stage II ( n=147), 4.9% and 8.8% of stage IIIa ( n=388), 7.2% and 16.6% of stage IIIb ( n=148), 8.9% and 20.5% and of stage IV ( n=114). Multivariate analysis showed @entity86 stage to be the factor most closely related to within the first 90 days. CONCLUSIONS: @entity5 stage but not type of resection is the strongest predictor of postoperative mortality in these subpopulations.
