    Abstract:
    PURPOSE: The purpose of this study was to assess the benefits of stereotactic vacuum-assisted breast biopsy in patients with non-palpable microcalcification detected on mammography. METHODS: Between October 2001 and November 2003, stereotactic Mammotome biopsies were performed for 150 microcalcified lesions on mammography using the prone-type stereotactic vacuum-assisted breast biopsy system (Mammotest and Mammovision, Fischer, Denver, USA) . The mammography findings were classified according to the guidelines of The Japan Radiological Society/The Japan Association of Radiological Technologists. Ninety-eight cases were category 3, 38 were category 4, and 14 were category 5. RESULTS: All cases were determined to be cases of microcalcification by specimen radiography or histology. Complications were negligible. One hundred twenty of the cases were mastopathy, and 30 of them were breast cancer (14 were ductal carcinoma in situ, 7 were ductal carcinoma in situ with microinvasion, and 9 were invasive ductal carcinoma). Twenty-seven breast cancers were diagnosed as category 4 or 5 (51.9%) on mammography. The operative stages of 27 cases were as follows: 7 were stage 0, 17 were stage 1, and 3 were stage 2A. Twenty-four of 27 (88.9%) were early breast cancers. CONCLUSION: Mammotome biopsy is a safe and useful modality for the histological diagnosis of non-palpable microcalcifications.
