Long-Term Follow-up of Lobular Neoplasia (Atypical Lobular Hyperplasia/Lobular Carcinoma In Situ) Diagnosed on Core Needle Biopsy

摘要

Background Lobular neoplasia (LN) includes atypical lobular hyperplasia (ALH) and lobular carcinoma in situ (LCIS). LN often is an incidental finding on breast core needle biopsy (CNBx) and management remains controversial. Our objective was to define the incidence of malignancy in women diagnosed with pure LN on CNBx, and identify a subset of patients that may be observed.
