Purpose Our purpose was to identify the factors in a breast core needle biopsy (CNB) of atypical ductal hyperplasia (ADH) that are predictive for carcinoma in the subsequent excision specimens.
Methods We performed a retrospective pathologic review of 50 cases that were diagnosed as ADH via the CNB and that had the corresponding excision specimens.
Results The size of the largest ADH foci in the CNBs was 0.8±0.6 mm (mean±SD) for benign proliferative disease (BPD, n=12), 1.0±0.5 mm (mean±SD) for ADH (n=9) and 1.3±0.8 mm (mean±SD) for malignant lesions (n=29) in excision specimens (p=0.105). Among the 30 cases showing stromal alterations around the ducts with ADH in the CNBs, 9 cases (30.0%) were BPD or ADH and 21 cases (70.0%) were malignant lesions in the excision specimens (p=0.004).
Conclusion As the stromal alterations around the ADH were noted in the CNB, there was an increased likelihood that more advanced lesions would be identified in the surgical excision specimens.
