Available in PDF, EPUB and Kindle. Book excerpt: Advanced breast biopsy instrumentation (ABBI) is a device for biopsy of suspicious small lesions of the breast for diagnosis. The procedure involved utilises a stereotactic imaging system and is minimally invasive. From the literature available on ABBI, the sensitivity and specificity of the procedure from the studies retrieved was unclear, most of the studies being quasi-experimental in design, and providing limited detail on patient selection, blinding and randomisation. There is a need for women who are found, via mammography, to have suspicious small breast lesions investigated, to determine whether the lesion is invasive, in-situ, or benign. The limited safety data available suggests that the procedure is safe. Currently there is insufficient evidence to conclude that ABBI is superior to the standard diagnostic tests for breast lesions of less than 10 mm, which are core biopsy or hookwire breast localisation needle for open surgical biopsy. Since there is insufficient evidence to conclude that ABBI is superior to the standard diagnostic tests, no cost-effectiveness analysis has been undertaken.
