title: Pulmonary Metastasectomy in Adult Patients with Synovial Sarcoma: A Single-Center Experience.
abstract: BACKGROUND
  This study assessed the efficacy of pulmonary metastasectomy for synovial sarcoma in adult patients.
  
  
  METHODS
  Fifty patients, diagnosed with pulmonary metastasis from June 1990 to August 2010, were reviewed retrospectively. Twenty-eight patients underwent complete pulmonary metastasectomy, and their survival was evaluated. Age, sex, time to metastatic progression, laterality, number of tumors, size of largest nodule, and number of metastasectomies were analyzed as potential prognostic factors.
  
  
  RESULTS
  In all, 29 patients underwent at least one pulmonary metastasectomy, and 51 resections were performed. One intraoperative mortality occurred, and the 5-year survival rate was 58.4%. Bilateral metastases and early metastatic progression were associated with poor survival in multivariate analyses.
  
  
  CONCLUSIONS
  Surgical resection can be a good option for treating pulmonary metastasis in patients with synovial sarcoma. Repeated resection was feasible with low mortality and morbidity.
