Purpose
The purpose of the study was to analyse the development of MRI-guided vacuum-assisted biopsies (VAB) and to compare the procedure with stereotactic and sonographic VAB in Switzerland on the basis of data available the database hosted by the MIBB-groupfrom the years 2009-2011.
The study will also examine whether the MRI-guided procedure results in differences in the technical success rate,
the complication rates and the accuracy of histological results when compared to the stereotactic and sonographic procedures.
Methods and Materials
The working group “Image-guided Minimally Invasive Breast Biopsies” (MIBB) of the Swiss Society of Senology (SGS) recordsall minimally invasive breast biopsies (VAB) performed in Switzerland for the purposes of documentation and quality assurance on behalf of the Federal Office of Public Health [BundesamtesfürGesundheit (BAG)] within the scope of legal specifications.
The MIBB working group has also developed quality guidelines which define minimal standards for the execution of a vacuum biopsy for the physician and the institute.
Stereotactic and sonographic VAB have been recorded since 2008....
Results
Vacuum biopsy developments in Switzerland between 2009 and 2011
Between the years 2009 and 2011,
a total of 9113 vacuum-assisted breast biopsies with specification of the biopsy method were performed in Switzerland and entered in the database. Of these,
557 (6%) were performed on an MRI-guided basis,
5391 (59%) on a stereotactic basis (at a dedicated stereotaxis table),
569 (6%) on a stereotactic “upright” device and 2596 (28%) on a sonographically guided basis.
MRI-guided biopsies displayed a growth rate of 97% over the entire period...
Conclusion
The study showed that the totalnumber of image-guided vacuum biopsies in Switzerland remained mostly constant throughout the study period with an overall growth rate of 2%,
whereby the number of MRI-guided VAB rose significantly by 97%. The growth rate for the procedure using a stereotaxis table was 14%.
The growth rates for the procedures using an “upright” device and sonography declined by 1% and 31% respectively.
The total complication rate for MRI-guided VAB (8%) showed no significant difference from the rates for the procedure using...
