title: Surgical outcome of combined pulmonary and atrial resection for lung cancer.
abstract: OBJECTIVE
  The study was carried out to assess the short and long-term outcome of patients with non-small cell lung cancer infiltrating the left atrium treated by surgery.
  
  
  METHODS
  We retrospectively collected the hospital files of twenty-three consecutive patients operated on between 1982 and 2001 in two units of Thoracic Surgery. Four patients received an induction regimen. Fourteen right pneumonectomies, 8 left pneumonectomies and 1 right inferior lobectomy were performed. No cardiopulmonary bypass was employed.
  
  
  RESULTS
  In all patients the diagnosis of T4 atrial invasion was confirmed by pathological examination. A complete resection was achieved in nineteen patients (83%). With respect to nodal staging, there were 13 N0, 5 N1 and 4 N2 cases, respectively. Two deaths occurred during the one month postoperative period (9%). Three patients had postoperative atrial fibrillation. Two other patients had postpneumonectomy empyema without bronchopleural fistula and recovered, one after thoracoscopic debridement and the second after open window thoracostomy. Follow-up was completed on September 2002; only one patient was lost to follow-up. Median survival, excluding the perioperative mortality, was 20 months (range 4 - 62 months). The survival rate, calculated with the Kaplan-Meier method, was estimated as 63% at 1 year, 2 % at 3 years and 10% at 5 years. Using a Cox model analysis, lymph node stage and completeness of resection were not independent prognostic factors.
  
  
  CONCLUSIONS
  In cases of NSCLC with left atrial invasion complete resection is technically feasible in most instances without cardiopulmonary bypass. The acceptable operative risk and the encouraging long-term survival observed in this series suggest that NSCLC invading the left atrium should not be systematically considered as a definitive contraindication to surgery.
