title: [Significance of sonographically guided percutaneous needle biopsy in the diagnostics of soft tissue tumors].
abstract: BACKGROUND
  The role of percutaneous needle biopsy in the diagnostics of soft tissue tumors is controversially discussed. The specificity of this method has been examined in this study based on the collective of patients treated in our university hospital. Secondly, the influence of the specialization of the treating surgeon has been evaluated.
  
  
  METHODS
  This study included 96 patients who underwent percutaneous needle biopsy and, if necessary, surgical resection. The specificity, logistic requirements and possible complications of percutaneous biopsy were evaluated. Special attention was paid to the influence of specialization of the treating surgical team on the specificity of the method.
  
  
  RESULTS
  The results of the biopsy were able to define the entity of the lesion correctly in 69.7 %, the dignity in 75.0 % and the grading in 72.0 % of the cases. In the group treated by a specialized team, the specificity of the method was 84.6 % concerning the entity of the lesion, 84.6 % concerning the dignity and 80 % concerning the grading. With regard to the entity the specificity was significantly increased (p < 0.05).
  
  
  CONCLUSIONS
  The findings show that percutaneous needle biopsy represents a logistically simple and efficient diagnostic method for soft tissue tumors which is rarely associated with complications. Subsequent treatment should be performed in a specialized centre.
