ABSTRACT
OBJECTIVE:
To evaluate the upgrade rate and delayed false-negative results of percutaneous vacuum-assisted removal (VAR) and surgical excision in women with imaging-histologic discordance during ultrasound (US)-guided automated core needle biopsy (CNB) of the breast and to validate the role of VAR as a rebiopsy method for these discordant lesions. MATERIALS ANDMETHODS:
Percutaneous US-guided 14-gauge CNB was performed on 7470 patients between August 2005 and December 2010. Our study population included 161 lesions in 152 patients who underwent subsequent rebiopsy due to imaging-histologic discordance. Rebiopsy was performed using VAR (n = 88) or surgical excision (n = 73). We investigated the upgrade rate immediately after rebiopsy and delayed false-negative results during at least 24 months of follow-up after rebiopsy. We also evaluated the clinicoradiological differences between VAR and surgical excision.RESULTS:
Total upgrade to malignancy occurred in 13.7% (22/161) of lesions at rebiopsy including both VAR and surgical excision 4.6% (4/88) of VAR cases (4/88) and 24.7% (18/73) of surgical excision cases (p < 0.001). Surgical excision was performed significantly more frequently in older patients and for larger-sized lesions than that of VAR, and a significant difference was detected between VAR and surgical excision in the Breast Imaging and Reporting and Data System category (p < 0.007). No delayed false-negative results were observed after VAR or surgical excision during the follow-up period.CONCLUSION:
Long-term follow-up data showed no delayed cancer diagnoses after US-guided VAR in imaging-histologic discordant lesions of the breast, suggesting that VAR might be a rebiopsy method for these lesions.
