title: [Preoperative axillary ultrasound in breast carcinoma: value of the method in routine clinical practice].
abstract: OBJECTIVE
  To evaluate the significance of routinely performed preoperative axillary sonography in breast cancer patients.
  
  
  METHODS
  191 patients with surgical treated breast cancer were analysed retrospectively. 74 patients of these had an axillary sonography done by 5 different examiners.
  
  
  RESULTS
  For detecting lymph node metastases sensitivity was 68.2% in all T-stages and 50% in T1-stages with a specificity of 100%. Classification of the axillary status (positive or negative for lymph node metastases) is possible in 90.5% for all T-stages and 94.9% for T1-stages. Microscopic and small lymph node metastases are missed by ultrasound. Compared to axillary palpation, sonography is better.
  
  
  CONCLUSIONS
  Preoperative axillary sonography is an useful diagnostic method even when done routinely. If further criteria are considered, axillary dissection could be avoided in some patients.
