Stereotactic Core Needle Biopsy of Nonpalpable Breast Lesions Using a Conventional Mammography Unit with an Add-On Device
2003
OBJECTIVE. The purpose of this prospective study was to assess the accuracy of an add-on stereotactic unit for core needle biopsy of mammographic lesions.SUBJECTS AND METHODS. Between September 1994 and February 2001, 506 stereotactic core needle biopsies of mammographic lesions in 492 patients were performed in our center on a mammography unit with add-on stereotactic equipment. Of the initial 92 patients, 80 underwent stereotactic core needle biopsy and surgical excision simultaneously. In subsequent cases, surgical biopsy was performed after core biopsy in patients who had malignant or atypical histologic results or discordance between mammographic and pathologic findings. Follow-up mammography was advised for all patients whose core biopsy results were diagnosed as benign lesions.RESULTS. Histologic results for 506 lesions undergoing stereotactic core needle biopsy were as follows: 113 (22.3%) were malignant; 369 (72.9%), benign; and 24 (4.7%), atypical. Of 113 malignant lesions identified at stereota...
