title: [Ultrasound guided breast biopsy--a retrospective study and literature review].
abstract: OBJECTIVE
  The purpose of this study is to determine the accuracy and clinical usefulness of ultrasound guided core biopsy for diagnosing suspicious radiologically detected breast lesions.
  
  
  METHODS
  We retrospectively evaluated the results of percutaneous core biopsy with 14-gauge needles performed over a period of 14 months on 229 suspicious lesions detectable on mammography and/or ultrasound exam (BI-RADS 4 or 5). The imaging-histological concordance was ascertained for each lesion. In cases of discordance, repeat biopsy or surgical excision was performed. Six-month ultrasound control was recommended in cases of benign lesions. For borderline and malignant lesions a surgical excision was done. Concordance between biopsy results and subsequent examinations (surgical excision or follow-up) was also evaluated.
  
  
  RESULTS
  Histological analysis of core biopsy samples showed 143 (62.4%) benign lesions, 21 (9.2%) borderline lesions and 65 (28.4%) malignant lesions. Follow-up, repeated biopsy, or surgical excision showed four false negative cases. Accuracy of ultrasound guided core biopsy was 98.3%.
  
  
  CONCLUSIONS
  Ultrasound guided core biopsy is a safe and reliable method for diagnosing suspicious breast lesions without any significant complications as was reported in previous studies.
