Intraoperative Ultrasound Can Facilitate the Wire Guided Breast Procedure for Mammographic Abnormalities

Abstract

Wire guided breast procedures are the most commonly used breast conserving operation for nonpalpable cancers. We did a retrospective review of all patients who underwent the wire guided breast procedure at a county hospital with an associated surgical residency program. Twenty-eight patients underwent the procedure with intraoperative ultrasound from June 2009 to March 2010. Breast cancer patients who underwent a wire-guided lumpectomy with intraoperative ultrasound had a lower rate of positive margins (9% vs 26%, P = 0.28) and a smaller volume of tissue removed (126 cm3 vs 146 cm3, P = 0.57). For wire guided excisional biopsy, the volume of tissue removed was smaller in the intraoperative ultrasound group (30 cm3 vs 44 cm3, P = 0.17) and the targeted area was more likely to be removed in one specimen (1.1 vs 1.5, P = 0.03). Intraoperative ultrasound can improve surgical outcomes of the wire guided breast procedure.
