PURPOSE: The characteristics of tumor extension determine whether pneumonectomy or lobectomy with bronchoplasty should be performed for central lung cancer. We investigated how the characteristics of tumor extension determined the operative methods and the surgical outcomes. METHODS: We conducted a retrospective chart review of 151 patients with positive bronchoscopic findings who underwent lung cancer operations between January 1995 and March 2002. Twenty-five patients underwent pneumonectomy, 88 underwent lobectomy/segmentectomy (Lob/Seg), and 38 underwent Lob/Seg with bronchoplasty. RESULTS: Pathologic staging was higher in the pneumonectomy group than in the Lob/Seg groups, with or without bronchoplasty (P = 0.002). Interlobar extension and hilar lymph node involvement were more frequent, and mucosal invasion was less frequent, in the pneumonectomy group than in the Lob/Seg with bronchoplasty group. The frequencies of all specific pulmonary complications and 30-day mortality were similar among the three groups. The 5-year overall survival rates were 23.7%, 51.5%, and 72.8% for the pneumonectomy, Lob/Seg, and Lob/Seg with bronchoplasty groups, respectively (P = 0.0004). There was a significant difference in survival between patients with mucosal and those with submucosal types of lung cancer (P = 0.0114). CONCLUSIONS: Lob/Seg with bronchoplasty was feasible without a higher risk of operative complications or poorer long-term survival. The nature of tumor extension was important in the selection of operative methods and in predicting survival.
