Operative risk and prognostic factors of typical XXXX .

@entity5 @entity1 @entity2558 @entity3
BACKGROUND: This study estimated operative risk and examined factors determining long-term survival after resection of typical @entity5 . METHODS: From 1976 to 1996, 139 consecutive @entity1 (66 male and 73 female @entity1 with a mean age of 47 +/- 15 years) underwent thoracotomy for typical @entity5 . The @entity5 were centrally located in 102 @entity1 (73.4%). RESULTS: Radical resection was performed in 106 @entity1 (7 pneumonectomies, 13 bilobectomies, and 86 lobectomies) and conservative resection in 33 (3 segmentectomies, 3 wedge resections, 20 sleeve lobectomies, and 7 sleeve bronchectomies). There were no postoperative deaths. Complications occurred in 19 @entity1 (13.7%). The morbidity rate was not increased after bronchoplastic procedures (chi 2 = 0.033, not significant). Staging was @entity2558 in 107 @entity1 (77.0%) and pT2 in 32 (23.0%); 13 @entity1 (9.4%) had nodal @entity3 . Seventeen @entity1 have died (12.2%), during follow-up, but only three deaths were related to the disease. The overall survival rate at 5, 10, and 15 years was estimated to be 92.4%, 88.3%, and 76.4%, respectively; estimated disease-free survival was 100% at 5 years and 91.4% at 10 and 15 years. Estimated survival of @entity1 with lymph node @entity3 was 100% at 5, 10, and 15 years. Univariate analysis failed to demonstrate any prognostic significance for sex, @entity5 size (T1 versus T2), @entity5 location (central versus peripheral), and type of resection. CONCLUSIONS: These data confirm an excellent prognosis after complete resection of typical @entity5 , including those with lymph node @entity3 . Parenchyma-saving resections should be preferred.
