Interdisciplinary Consensus on the Use and Technique of Vacuum-assisted Stereotactic Breast Biopsy

Purpose: Quality assurance of stereotactic vacuum-assisted breast biopsy (VB).

Method: A consensus was achieved based on the existing literature and the experience of VB users (Ethicon Endosurgery, Norderstedt).

Results: The imaging work-up must be completed according to existing standards before an indication for stereotactic VB is established. Indications include microcalcifications and small non-palpable masses; for the time being lesions very close to the skin and architectural distortions (radial scar) are considered less suitable. Acquisition of >20 cores (11 Gauge) should be routinely attempted (goals: as complete a removal of small lesions as possible, thereby increasing diagnostic confidence and reducing so-called 'underestimates'). The pre/post-fire and post-biopsy stereotactic images and a post-biopsy orthogonal mammogram must be documented. All cases with no or uncertain histopathological correlation require discussion in a regular interdisciplinary conference and a documented consensus concerning further work-up or therapy. Standardised documentation of the primary findings and follow-up mammography after approximately 6 months is requested.

Conclusion: This consensus includes protocols for the establishment of an indication, performance indicators, interdisciplinary interpretation and therapeutic recommendation, documentation and follow-up. It does not replace official recommendations for percutaneous biopsy.
