title: Sleeve lobectomy versus pneumonectomy: tumor characteristics and comparative analysis of feasibility and results.
abstract: BACKGROUND
  Sleeve lobectomy (SL) seems to have better results than pneumonectomy. Some authors propose to extend its indications. The aim of this study was to compare postoperative results, locoregional recurrence, and survival after sleeve lobectomy and pneumonectomy in focusing on right upper lobe cancer.
  
  
  METHODS
  From 1984 to 2002, 973 lung resections were performed for T1, T2, and bronchial T3 right upper lobe non-small cell lung cancer. There were 756 lobectomies (L group), 151 pneumonectomies (RP group), and 66 sleeve lobectomies (SL group). The RP group was further divided with regard to intrapulmonary lymph node involvement. Pneumonectomy 1 (RP1) was a group of N0, intralobar N1, and skip metastasis involvement (N0-N2). Pneumonectomy 2 (RP2) was a group of extralobar N1 and nonskip metastasis involvement (N1-N2). Postoperative results were compared among SL, L, and RP groups. Survival was compared between the two homogeneous groups for oncologic characteristics (SL, RP1).
  
  
  RESULTS
  Statistical comparison of 5-year actuarial survival showed a significant difference favoring SL (SL: 72.5%/ RP1: 53.2%; p = 0.0025). Postoperative mortality was higher after RP (L: 2.9% / SL: 4.5%/ RP: 12.6 %). Significant factors limiting SL were tumor size, extralobar N1, and main bronchus involvement (p = 0.000026, 0.0002, and 0.005, respectively).
  
  
  CONCLUSIONS
  Immediate and long-term survival appears better after sleeve lobectomy than right pneumonectomy for comparable stages of right upper lobe cancer. For frequency to increase by systematic attempt at SL, limited by large tumors and extralobar N1 involvement, the only way should be after favorable response to induction chemotherapy.
