The objective of this study was to assess the usefulness of stereotactic large-core needle biopsy (LCNB) in the management of nonpalpable breast lesions (NBL) and compare it with stereotactic fine-needle aspiration biopsy (SFNA) performed simultaneously in a significant number of cases. From November 1993 through June 1997, 510 consecutive patients with NBL underwent 14-gauge LCNB with 354 women undergoing simultaneous 21-gauge SFNA in the same lesson. Mammographic findings lesion size, number of core biopsy specimens, complications and diagnoses of both techniques were analysed. Surgical biopsy, tumorectomy or mastectomy was indicated for malignancy or poor correlation between SFNA or LCNB results and clinical or radiological findings. Values of diagnostic accuracy of both LCNB and SFNA were determined. The ratio benign surgical biopsies/malignant surgical biopsies (BB/CB) of the series was calculated. A total of 171 patients underwent surgical treatment: in 31 (18.1%) a benign process or atypical ductal hyperplasia was the final diagnosis. The ratio BB/CB was 0.22. Sensitivity and specificity were 93.2 and 100%, respectively, for LCNB, and 77.2 and 92.3%, respectively, for SFNA with cytological analysis. Large-core needle biopsy provides more accurate diagnosis than SFNA in the management of nonpalpable breast lesions and obviates a surgical diagnostic procedure in a significant number of cases.
