Abstract

The purpose of this study is to evaluate the clinical usefulness of ultrasonography (US)-guided Mammotome biopsy by a new large 8-gauge biopsy probe. Seventeen cases were included in this study: 14 cases of ultrasonically benign-looking nodules of breasts and three cases of entensive m icrocalci fications by film mammography. We analyzed the safety and patient acceptance of Mammotome biopsy and the results of short-term follow-up US study. Pathological results of breast nodules revealed 12 cases of fibroadenoma and two cases of fibrocystic change; and the results of microcalcifications showed two cases of invasive ductal carcinoma and one case of ductal carcinoma in situ. We removed the targeted nodule completely in 9 cases (64%). Adverse events included mild-to-moderate pain during or after biopsy; ecchymosis; and some bleeding. Patient satisfaction and acceptance were high. Concerning short-term follow-up US study; there were four cases of hematoma (24%). We conclude that US- guided Mammotome biopsy using a large 8-gauge biopsy probe is feasible and safe diagnostic modality. This procedure would be diagnostic as well as therapeutic in the management of breast nodules and in the evaluation of mammographically visible extensive microcalcifications.
