Study Using MarginProbe® Presented at American Society of Clinical Oncology (ASCO) 2014 Breast Cancer Symposium

PAOLI, Pa., Nov. 7, 2014 /PRNewswire/ -- Results of the study Combined experience at three breast centers with routine use of an intraoperative margin assessment device including comparison to historical re-excision rates were presented by Dr. Mary L. Sebastian as part of the general poster session at the recent ASCO Breast Cancer Symposium. The study reports an analysis of re-excision rates in Breast Cancer Surgery (BCS) cases when using MarginProbe compared to historical re-excision rates. Re-excision in breast conserving cancer surgery refers to the event in which a patient is called back for a second operation after the results of her final pathology report are available several days after the initial operation.  The device was routinely used in a series of 165 consecutive BCS cases, by 4 surgeons in 3 centers.  

"The results of this study were significant in that they showed a 62% relative reduction in re-excision rates.  Each of the four surgeons who participated saw a sizeable reduction in their individual re-excision rate," said Dr. Sebastian.  "Another noteworthy finding is that using the recently updated SSO guidelines of positive margin defined as tumor on ink, in 18% (30/165) of the cases the primary (main) lumpectomy specimen, prior to intra-operative assessment, had positive margins. In 73% (22/30) of these cases use of the device led to identification of the positive margins."

Numerous studies have shown a significant reduction in positive margins when using MarginProbe," said Dan Hashimshony PhD, CEO of Dune Medical Devices.  "We are excited that the body of evidence showing the positive effects on patient outcome when using MarginProbe is growing. The findings in this specific study reinforce the fact that routine usage of MarginProbe in BCS procedures directly impacts the clinical outcome and is beneficial to patients."
