BACKGROUND: Percutaneous biopsy (BP) is a valid alternative to open surgical biopsy. The aim of our study was to evaluate the results and diagnostic value of vacuum-assisted core biopsy (VACB; Mammotome) and advanced breast biopsy instrumentation (ABBI). METHODS: From June 1999 to December 2001, 360 BPs were performed: all patients had dubious mammography lesions not confirmed by ultrasonography. Indications were as follows 264 (73.3%) microcalcifications, 64 (17.8%) nodular opacities, and 32 (8.8%) parenchymal distortions. RESULTS: All BPs were performed with a digital stereotactic table with a vacuum suction aspiration system for VACB and a cutting cannula for ABBI. All BPs were correctly performed. Seventy-one (19.7%) lesions were malignant, whereas 258 (71.6%) were benign: 31 (8.6%) of the lesions removed with VACB were atypical ductal hyperplasia. CONCLUSIONS: BP is a valid method for the diagnosis of nonpalpable breast lesions. In our experience, VACB is the method of choice because it is easy to perform and has high adaptability.
