Study of the Outcomes of Intraoperative Margin Assessment With MarginProbe
Completed · Not applicable
Conditions studied: Breast Cancer
In brief
The combination of breast conserving surgery (lumpectomy) with radiation therapy has been shown to result in equivalent overall survival rates compared to mastectomy for the local treatment of breast cancer. As a result, the majority of patients diagnosed with breast cancer in the United States undergo lumpectomy as their primary surgical therapy. Multiple studies have demonstrated the association between positive lumpectomy margins and an increased risk of ipsilateral breast tumor recurrence, even with postoperative radiation. Studies report 20-40% of lumpectomy procedures result in one or more involved (positive) surgical margins, leading to the need for further surgery, emotional distress, poorer cosmesis, delay to adjuvant treatments, and increased cost. Current available intraoperative margin assessment techniques include specimen Xray, gross pathology, frozen section, and touch prep cytology. To reduce the incidence of positive margins, the MarginProbe (Dune Medical Devices, Caesarea, Israel) was developed to provide real-time, intraoperative assessment of the presence of tumor at the lumpectomy margin. In the current study, the investigators aim to determine the effectiveness of MarginProbe as an adjunctive tool to standard practice for intraoperative identification of tumor at lumpectomy margins, and its ability to reduce positive margins and decrease the need for additional surgical procedures.
