title: Extended pulmonary resections of advanced thoracic malignancies with support of cardiopulmonary bypass.
abstract: OBJECTIVE
  Complete resection of advanced pulmonary malignancies infiltrating the heart or the great vessels may require the application of cardiopulmonary bypass (CPB). Extracorporal circulation, however, is known to cause lung injury and may be harmful especially in pneumonectomies.
  
  
  METHODS
  Over a period of 10 years extended pulmonary resections requiring cardiopulmonary bypass were analyzed in a retrospective study.
  
  
  RESULTS
  From August 1993 to August 2003, 13 patients underwent an extended pulmonary resection for curative indications, requiring support by CPB. Underlying diseases were sarcomas (n=8), non-small cell lung carcinomas (n=3), and others (n=2). Pneumonectomies were performed in nine and lobectomies in four cases. In the majority of cases, several cardiac structures, predominantly the left atrium (n=9), were affected. In four patients (31%), the indication for a CPB-supported procedure was not electively planned, but made intraoperatively. Complete en-bloc resection (R0) was achieved in 12 of 13 cases (92%). The 30-day mortality rate was 15% (n=2). Major complications observed were acute lung injury (n=4), right heart failure (n=1), and multi-organ failure (n=1). The cumulative survival at 1, 3, and 5 years in patients presenting with sarcomas was 62.5% compared to 33%, 0%, and 0%, respectively, in patients with non-small cell carcinoma (n=3).
  
  
  CONCLUSIONS
  Our results encourage the application of CPB in extended pulmonary resections to achieve complete resections. In carefully selected patients, especially those with sarcomas, the radical surgical procedure associated with increased pulmonary complications allows for significantly prolonged survival and quality of life.
