Lobular Neoplasia at 11-Gauge Vacuum-Assisted Stereotactic Biopsy: Correlation with Surgical Excisional Biopsy and Mammographic Follow-Up

Abstract

The known association of lobular neoplasia with high-risk and malignant lesions at surgical biopsy requires careful consideration when lobular neoplasia is diagnosed as the most severe histologic entity at SVAB. The diagnosis of lobular neoplasia at 11-gauge SVAB is not reliable in view of the 19% upgrade rate at the time of surgical excisional biopsy in our study. No predictive mammographic features allowed distinction between the patients with lesions that were upgraded at the time of surgery from those whose lesions were not upgraded.
