title: [Complete resection of urothelial cancer metastases with curative intent].
abstract: BACKGROUND
  Recent publications suggest that a subgroup of patients can benefit from surgical removal of transitional cell carcinoma (TCC) metastases in addition to systemic chemotherapy. We report the combined experience and outcome of patients undergoing resection of TCC metastases at 15 uro-oncologic centers in Germany.
  
  
  METHODS
  Forty-four patients with distant metastatic TCC of the bladder or upper urinary tract underwent resection of all detectable metastases in 15 different German uro-oncological centers between 1991 and 2008 in an attempt to be rendered free of disease.
  
  
  RESULTS
  The resected metastatic sites consisted of retroperitoneal lymph nodes (56.8%), distant lymph nodes (11.3%), lung (18.2%), bone (4.5%), adrenal gland (2.3%), brain (2.3%), small intestine (2.3%), and skin (2.3%). The treatment sequence included systemic chemotherapy in 35/44 (79.5%) patients before and/or after surgery. Median survival times from initial diagnosis of metastatic TCC and subsequent resection were as follows: overall survival, 35 and 27 months, respectively; cancer-specific survival, 38 and 34 months, respectively; and progression-free survival, 19 and 15 months, respectively. Overall 5-year survival from metastasectomy for the entire cohort was 28%. Seventeen patients were still alive without progression at a median follow-up time of 8 months. Seven patients without disease progression survived for more than 2 years and remain free from tumor progression at a median of 63 months.
  
  
  CONCLUSIONS
  The results in this selected cohort confirm that long-term cancer control and possibly cure can be achieved in a subgroup of patients following surgical removal of TCC metastases. However, prospective data to identify patients most likely to benefit from this aggressive therapeutic approach are lacking. Therefore, metastasectomy in patients with disseminated TCC remains investigational and should be offered only to those with limited disease as a combined-modality approach with systemic chemotherapy.
