A prospective study of the removal rate of imaged breast lesions by an 11-gauge vacuum-assisted biopsy probe system

Am J Surg. 2001 Oct;182(4):335-40. doi: 10.1016/s0002-9610(01)00723-1.


Background: More than 1,000,000 breast biopsies are performed each year as a result of abnormalities identified by imaging techniques. This prospective study was designed to determine whether complete removal of the imaged evidence of an abnormal mammogram or ultrasonogram could be achieved with percutaneous image-guided procedures using an 11-gauge vacuum-assisted biopsy probe.

Methods: Forty-five women over the age of 18 years entered the study; 50 breast lesions were identified by ultrasonography or mammography. Biopsies were obtained using an 11-gauge vacuum-assisted probe. At 6 months after biopsy, ultrasonography or mammography examinations of the biopsy site were performed.

Results: Forty-five lesions (90%) were completely removed. At 6 months after biopsy, 82% of the sites were lesion free. The percentage of nonrecurring lesions at 6 months after surgery was inversely related to the size of the original lesion.

Conclusion: This device allows biopsies to be successfully combined with complete removal of the imaged lesion in a one-step minimally invasive procedure.
