[Early experience with the advanced breast biopsy instrumentation system in a multicentre study].

Early Experience with the Advanced Breast Biopsy Instrumentation System in a Multicentre Study In an Austrian multicentre trial between September 1998 and December 2001, 474 procedures were performed with the Advanced Breast Biopsy Instrumentation (ABBI), and 389 were entered in the protocol. For reasons of patient comfort, radiological accuracy and low complication rate, the stereotactic excision biopsy with the ABBI system is a useful alternative to 'open' biopsy of non-palpable breast lesions, although there are technical limitations. The question of the therapeutic option in breast cancer cannot be answered yet.
