N2 - Objectives: The increasing accuracy of large-bore (11- or 8-gauge) vacuum-assisted core needle biopsies (VACNB) has challenged the commonly-accepted practice that surgery is needed for definitive diagnosis when atypical ductal hyperplasia (ADH) is found on VACNB. This study seeks to demonstrate the impact of increased VACNB caliber on the pathologic upgrade rate of ADH. Methods: Patients diagnosed with isolated ADH by VACNB who subsequently underwent surgical excision at our tertiary medical center were retrospectively studied. Demographics, needle gauge, number of needle passes, and pathology results were analyzed. Results: From June 1996 to June 2016, approximately 3740 VACNBs were performed. 139 patients were diagnosed with isolated ADH on VACNB and underwent surgical excision. 30 patients (22%) were upgraded to ductal carcinoma in-situ or invasive cancer; 17 upgrades (21%) from 11-gauge CNB vs. 13 upgrades (23%) from 8-gauge CNB (p = 0.67). Conclusion: Increasing core needle biopsy size from 11 g to 8 g does not decrease the rate of pathologic upstaging at the time of surgical excision. Surgical excision of ADH is still required for complete diagnosis.
