Abstract: OBJECTIVE:To review the concordance between pathologists in the diagnosis of atypical ductal hyperplasia of the breast. METHODS:Systematic review of articles registered in the PubMed database with the terms “pathologists” and “atypical ductal hyperplasia”, “atypical ductal hyperplasia” and “interobserver variability”, in Embase with “interobserver agreement in atypical ductal hyperplasia” and Lilacs with the terms in Spanish “patólogos” and “hiperplasia ductal atípica”, without the use of filters, between 03/16/2022 and 03/26/2022 searching for articles that assess inter-observer agreement in the diagnosis of atypical ductal hyperplasia by using the kappa statistic. Review articles, conference proceedings, and commentaries were excluded. RESULTS:With the search terms, 507 publications were found. Of these, 491 were excluded from the screening by title and abstract. Of the full reading of the remaining articles, 6 were selected for qualitative analysis. The kappa values ranged from slight agreement, kappa = 0.17, to substantial agreement, 0.69 obtained from pathologists dedicated or experienced in breast pathology and who received a prior tutorial session to review the general criteria for atypia. CONCLUSIONS:This study reviews the reproducibility in the diagnosis of atypical ductal hyperplasia. A better concordance was obtained with a previous teaching process offered to pathologists dedicated or experienced in breast pathology.
