  • Atypical ductal hyperplasia on vacuum-assisted breast biopsy: suspicion for ductal carcinoma in situ can stratify patients at high risk for upgrade HUMAN PATHOLOGY Allison, K. H., Eby, P. R., Kohr, J., DeMartini, W. B., Lehman, C. D. 2011; 42 (1): 41-50

    Abstract:

    We evaluated 97 cases of review-confirmed atypical ductal hyperplasia found on stereotactic vacuum-assisted breast biopsy of suspicious calcifications. The number and size of foci of atypical ductal hyperplasia and presence of a micropapillary component were noted. In addition, we recorded if a case was considered "atypical ductal hyperplasia suspicious for ductal carcinoma in situ" using specific qualitative criteria. The upgrade rate was 20.6% (20/97) for all cases and 48% (12/25) for cases suspicious for ductal carcinoma in situ. Suspicion for ductal carcinoma in situ was found to be a strong predictor of upgrade with an odds ratio of 7.4 (P = .0003). Suspicious cases with nuclear features bordering on intermediate nuclear grade had the highest upgrade rate of 75% (6/8). Cases with ? 3 foci had significantly higher upgrade rates (28%) than those with less than 3 foci (11%), but focal atypical ductal hyperplasia did upgrade (P = .04). In conclusion, qualitative features of atypical ductal hyperplasia on core biopsy such as suspicion for ductal carcinoma in situ may help stratify patients at the highest risk for upgrade.
