Lobular carcinoma in situ/atypical lobular hyperplasia on breast needle biopsies: does it warrant surgical excisional biopsy? A study of 27 cases.
Ann Diagn Pathol. 2010 Aug; 14(4):251-5.AD

Abstract

Lobular neoplasia including lobular carcinoma in situ (LCIS) and atypical lobular hyperplasia (ALH) may be identified in breast core needle biopsies as incidental findings or associated with microcalcifications. There are no general consensus guidelines for follow-up management in patients when lobular neoplasia is the only abnormal finding on core needle biopsy. The aim of this study was to evaluate our experience in the follow-up of these patients. A total of 3163 breast core needle biopsies were retrieved from the surgical pathology files between 2003 and 2009; among them, 56 (1.8%) cases were identified with a diagnosis of ALH or LCIS. Eleven cases were excluded because of the presence of a concurrent more severe lesion in the biopsies that mandated excision. The remaining 45 cases contained only ALH or LCIS and otherwise benign breast tissue; 27 had surgical excision follow-up. In the surgical excision specimens, 5 (19%) of 27 cases showed more severe lesions or were "upgraded" (3 invasive ductal carcinomas, 1 invasive lobular carcinoma, and 1 ductal carcinoma in situ). Histologic features of the lobular neoplasia on the cores, including association with microcalcifications, pagetoid involvement of ducts, and extensive lobular involvement, were retrospectively evaluated. These histologic features were found to have no predictive value for a more severe lesion in the subsequent excision. We suggest that patients with LCIS/ALH on core needle biopsy should be considered for surgical excision to rule out a more significant lesion regardless of the histologic features.
