Evaluation of percutaneous vacuum assisted intact specimen breast biopsy device for ultrasound visualized breast lesions: Upstage rates and long term follow-up for high risk lesions and DCIS

Percutaneous biopsy of ultrasound visualized lesions was performed accurately using IntactR. Upstaging was much lower with IntactR than with large-gauge core needles. High risk lesions, diagnosed with IntactR, have a very low upstage rate at surgical excision. It may be possible to observe these lesions without surgery when they present as ultrasound findings and undergo IntactR biopsy.
