OBJECTIVE: To determine if the breast imaging reporting and data system (BI-RADS) defines a group of patients with mammographic abnormalities in whom stereotactic core needle biopsy (SCNB) is appropriate. DESIGN: A blinded retrospective validation sample. SETTING: A university-affiliated hospital. PATIENTS: One hundred and nine consecutive patients who underwent fine-wire localization breast biopsy (FWLB) between Jan. 1, 1994, and June 1, 1999, with a known final pathological diagnosis. INTERVENTION: Blinded mammographic review and classification using the BI-RADS; review of corresponding pathological findings from FWLBs. OUTCOME MEASURES: Correlation of pathological findings with each BI-RADS category and analysis of the predictive value of clinical and radiologic features. RESULTS: BI-RADS findings were as follows: 0 malignant lesions in 10 category 3 cases, 18 malignant lesions (3 in situ, 15 invasive) in 68 category 4 cases and 24 malignant lesions (8 in situ and 16 invasive) in 31 category 5 cases. There was 1 malignant lesion in 22 category 4 cases in women younger than 50 years. CONCLUSIONS: SCNB should be applied to BI-RADS categories 3 and 4 (< 50 yr of age). FWLB should be reserved for category 4 (> 50 yr of age) and category 5 cases. This algorithm will reduce the morbidity and cost of breast biopsies in patients with nonpalpable mammographic abnormalities.
