title: [The role of surgery in bone metastases of renal cell carcinoma: 13 case reports].
abstract: BACKGROUND
  Surgery for osseous metastases seems to improve the patients with renal cell carcinoma. The goal of this study is to evaluate the efficacy and safety of surgery for osseous metastases from renal cell carcinoma.
  
  
  METHODS
  We performed 21 surgery for osseous metastases in 13 patients who have been treated for metastatic renal cell carcinoma at one institution between 2001 and 2007. The surgical procedure included curetage with cementing and or internal fixation, in bloc resection or surgical decompressive procedure. Disease-free and overall survival was calculated using Kaplan-Meïer analysis.
  
  
  RESULTS
  The overall patient survival rate at one year was 84%. The overall median survival time was 23months (IC95%; 16,9-78,1%). The disease-free survival was 19 months (IC95%: 26,7%-80,9%) after surgery. Positive margins were observed in 9 patients (R2) and negative margins in 8 patients (R0). R0 and R2 resections have no impact on local relapse. Minor complications occurred in two patients. There was no intra- or postoperative hemorrhage.
  
  
  CONCLUSIONS
  Surgery of osseous metastases is safe and effective and seems to improve outcomes of metastatic renal cell carcinoma.
