Methods and materials
B3 lesions identified by NCB (Needle Core Biopsy) and/or VAB (Vaacum-Assisted core biopsy) were classified in different histologic subtypes according to literature [4]: atypical ductal hyperplasia (ADH),
papillary lesions (PL),
lobular intraepithelial neoplasia grade 1 and 2 (LIN 1-2),
flat epithelial atypia (FEA),
radial scar/complex sclerosing lesions (RS/CLS),
fibroepithelial lesions (phyllodes tumor and fibroadenoma) and atypical nonspecific - not classifiable B3 lesions.
Histopathological results from NCB and/or VAB were compared with postsurgical histopathological findings,
calculating the positive predictive value (PPV) for malignancy (relative to all B3 lesions and to every single specific histologic subtype) and possible correlations with mammographic findings (microcalcifications,
architectural distorsions,
asymmetries and opacities).
