Abstract
Cytologic diagnosis of palpable breast masses is an accepted method for diagnosis. However, the high nondiagnostic rate causes repeat biopsy, unnecessary delays, and increased costs. Our purpose is to evaluate the use of ultrasound (US)-guided large-core needle biopsy as part of the minimally invasive multidisciplinary diagnosis of palpable breast masses. We studied 502 consecutive patients with 510 palpable solid breast masses seen and evaluated by a multidisciplinary team. Patients had US-guided core biopsy. Clinical–imaging–pathologic correlation (CIPC) was done in all cases. Core biopsy was deemed conclusive if CIPC was congruent and was used to guide definitive management. The median age of our patients was 39 years. Median tumor size was 2.2 cm. Of these cases, 463 (91%) had a conclusive diagnosis on CIPC. Core needle findings on 47 masses were nondefinitive to guide therapy (fibroepithelial lesion, atypical ductal hyperplasia, intraductal papilloma, CIPC). Three cancers were detected in this group on excisional biopsy. In conclusion, US-guided large-core needle biopsy is a sensitive method for diagnosis of palpable breast masses. Multidisciplinary correlation of clinical findings, imaging, and pathology is essential for success. This approach improves use of operating room resources and maximizes patient participation in the decision-making process.
