Abstract:The current recommendation for borderline breast lesions after core needle biopsy is for surgical excision due to a high rate of pathologic underestimation. With the use of vacuum-assisted core needle (VACN) biopsy devices, upgrade rates have improved, but still average 20 per cent. We routinely use larger bore VACNs (7- and 8-gauge) than previously reported (9 to 11-gauge). The aim of this study is to evaluate the upgrade rate to malignancy in patients undergoing VACN using larger bore needles. VACN biopsies … Show more
Upstaging was associated with lesions that were large, palpable or high grade. It was also associated with use of the 14-gauge needle method. Our scoring system might be helpful to identify patients who do not require sentinel lymph node biopsy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
