An Alternative to Stereotactic Breast Biopsy: Wire Localization Followed by Sonography-Guided Vacuum-Assisted Biopsy, Our Experience With 125 Cases
摘要
PURPOSE. To assess the performance and clinical value of mammographicallyguided hookwire localization and sonographically guided vacuum-assisted biopsy (VAB) of non-palpable breast lesions. MATERIALS AND METHODS. From 2014 January to 2016 October, 126 patients underwent mammography and were found to have cluster microcalcifications. These were subsequently determined to be category 3 and 4 according to Breast Imaging-Reporting and Data System and underwent mammography-guided hookwire localization and then ultrasound-guided VAB. Specimen mammography was taken to ensure microcalcifications were obtained. RESULTS. A total of 125 patients had VABs performed after hookwire localization. The mean procedural time was 24 minutes and microcalcification retrieval rate was 98.4% (123/125). Fifteen were found to be malignant, which included 5 invasive ductal carcinomas, and 10 ductal carcinomas in situ. Eleven high risk lesions were found, and these included 6 atypical ductal hyperplasia, 4 flat atypia, and 1 lobular carcinoma in situ. The other 99 biopsies yielded a mixed group of benign lesions which included 81 fibrocystic disease, 10 adenosis, 5 ductal hyperplasia, 2 apocrine metaplasia, and 1 papilloma. Complications included two cases of hematomas and one case of mastalgia, none were serious and required no further intervention. CONCLUSION. While unorthodox, mammographic hookwire localization and sonographically guided VAB seem to offer nearly comparable performance with stereotactic vacuum assisted biopsy, and may be a valid substitute in certain situations.
