title: [Resection of pulmonary metastases in 148 patients: analysis of prognostic factors].
abstract: OBJECTIVE
  To evaluate the prognostic factors for survival in a series of patients who underwent surgery for pulmonary metastases from primary tumors in distinct organs.
  
  
  METHODS
  This was a retrospective study of 148 patients operated between May 2001 and May 2007. Multivariate analysis was used to evaluate overall survival. Patients scheduled for tumorectomy were included provided their primary tumor was controlled and they had no extrathoracic recurrence and adequate cardiorespiratory function. The influence of the following prognostic factors was analyzed: number and diameter of the metastases, lymph node infiltration, complete resection, and, above all, histological type. A significance level of 95% was used.
  
  
  RESULTS
  A total of 90 men (60.81%) and 58 women (39.19%) were operated. The mean (SD) age was 56.5 (9.7) years. The actuarial survival at 6 years was 30.3% (n=45) and the median survival was 34 months. The factors that affected survival were the number of metastases (P< .05), diameter of the lesions (P< .05), lymph node infiltration (P< .05), complete resection (P< .05), and, above all, histological type (P< .05). Tumorectomy was the most commonly performed operation.
  
  
  CONCLUSIONS
  These results suggest that, in the absence of other therapeutic options and contraindications, we should operate on patients in whom the primary tumor is controlled and in whom complete resection can be performed. Even if factors associated with poor prognosis are present, the outcomes are always better than when surgery is not performed, particularly in view of the relatively low morbidity and mortality associated with this type of surgery.
