title: Comparison of morbidity, 30-day mortality, and long-term survival after pneumonectomy and sleeve lobectomy for non-small cell lung carcinoma.
abstract: BACKGROUND
  The advantage of sleeve lobectomy as an alternative to pneumonectomy for preserving lung function is obvious and among other arguments allows operating on patients with lung cancer who would not tolerate pneumonectomy. The purpose of this retrospective, nonrandomized study is to compare the early (30-day mortality) and late (5-year survival) outcomes of both procedures.
  
  
  METHODS
  The charts of 310 patients who underwent either pneumonectomy or sleeve lobectomy for lung cancer stages I to IIIA from 1987 to 1997 were reviewed. One hundred ninety-four patients underwent pneumonectomy, and 116 patients underwent sleeve lobectomy. Specific operative complications, i.e., anastomotic leakage versus stump dehiscence, perioperative complications, 30-day or in-hospital mortality, and 5-year survival were registered for comparison of the immediate risk of the respective procedures.
  
  
  RESULTS
  In the bronchial sleeve lobectomy group, the incidence of anastomotic leakage was 6.9% (8 of 116 patients) and the operative mortality was 4.3%. The incidence of bronchial stump fistulas after pneumonectomy was 3.6% (7 of 194 patients), and early mortality was 4.6%. All but 6 patients (98%) had a complete resection. Overall 5-year survival after sleeve lobectomy was 39% and after pneumonectomy, 27%. The distribution of 5-year survival stage by stage in either group is presented. Sleeve lobectomy, age younger than 65 years, pN0, and stage I are positive prognostic factors for long-term survival. In the multivariate analysis, pneumonectomy is a negative prognostic factor.
  
  
  CONCLUSIONS
  The indication for pneumonectomy versus sleeve lobectomy depends on the localization of the primary tumor on the one hand, and on cardiorespiratory function, which might be more often distinctly impaired in the sleeve group, on the other hand. This could explain why the mortality in the sleeve lobectomy group was identical with that in the pneumonectomy group. However, both techniques are appropriate treatment modalities of advanced lung cancer or patients with critical functional reserve. Therefore, whenever possible, sleeve lobectomy should be performed.
