Atypical ductal hyperplasia: Can some lesions be defined as probably benign after stereotactic 11-gauge vacuum-assisted biopsy, eliminating the recommendation for surgical excision? 87th Scientific Assembly and Annual Meeting of the Radiological-Society-of-North-America Jackman, R. J., Birdwell, R. L., Ikeda, D. M. RADIOLOGICAL SOC NORTH AMERICA. 2002: 548–54

Abstract

To determine if a subset of atypical ductal hyperplasia (ADH) lesions diagnosed at 11-gauge, directional, vacuum-assisted, prone, stereotactic biopsy fit the "probably benign" definition of a less than 2% chance of being carcinoma at subsequent surgical excision.Clinical, mammographic, and stereotactic biopsy features in 104 consecutive nonpalpable ADH lesions were correlated with the presence of carcinoma at lumpectomy. The results were analyzed with chi(2) statistic, with P <.05 indicative of significant difference.Surgical excision revealed carcinoma in 22 (21%) of 104 ADH lesions. The lowest incidences of carcinoma (each P <.02) were 16% (15 of 92) in patients with no personal history of breast carcinoma, 13% (nine of 67) when maximum lesion diameter was less than 10 mm, and 8% (three of 36) when 100% of the mammographic lesion was removed at stereotactic biopsy.No clinical, mammographic, or biopsy features alone or in combination could be used to define a substantial subset of probably benign lesions with a less than 2% chance of carcinoma at lumpectomy.
