title: [Evaluation of stereotactic core biopsies of the breast with the 10-gauge Vacora® biopsy device: a review of 541 procedures].
abstract: OBJECTIVE
  To evaluate stereotactic core biopsies of the breast with the 10-gauge Vacora(®) biopsy device.
  
  
  METHODS
  Retrospective study of 541 procedures in 502 patients performed between 2007 and 2009.
  
  
  RESULTS
  The procedure failed in 2% of cases, non-complicated hematomas occurred in 5% of cases and unsightly scars in two cases. A clip was deployed in 70% of cases, successfully in 99% of cases. The procedure was well tolerated in 88% of cases. Core biopsies confirmed a benign lesion in 55% of cases, borderline lesions in 19% of cases and malignant lesions in 26% of cases with complementary surgery performed in 40% of cases. For surgical lesions, sensitivity, specificity, PPV and NPV were 89%, 100%, 100% and 84% respectively. Atypical ductal dysplasia was under-estimated in 8% of cases while DCIS was under-estimated in 14% of cases. After review of the mammograms, 3% of Bi-Rads 4 lesions were reclassified as Bi-Rads 3 lesions, all benign at core biopsy. Half of these results were from screening mammography programs.
  
  
  CONCLUSIONS
  Results with the 10-gauge Vacora(®) biopsy device are similar to reports from the literature, mainly using the Mammotome system, with regards to tolerability and reliability for a lesser cost.
