Predictive factors for complete excision and underestimation of one-pass en bloc excision of non-palpable breast lesions with the Intact(®) breast lesion excision system.

Objective: Image-guided percutaneous biopsy is the recommended initial diagnostic procedure for suspicious mammographic lesions. This study was conducted to determine the accuracy of the Intact(®) breast lesion excision system (BLES) and to identify predictive factors for complete excision and underestimation.

Material And Methods: A prospective study was conducted between January 28, 2008 and April 30, 2009 on 166 biopsy procedures using Intact(®) biopsy device.
