New data demonstrating significantly lower re-excision rates with the
radar localization system compared to wire localization (WL) was presented recently at the 12th Annual Academic Surgical Congress by Quyen Chu. MD, from
Louisiana State University (LSU) Health Sciences Center-Shreveport, LA. LSU was an early adopter of SCOUT utilizing the technology since November 2015.
The study evaluated 26 SCOUT cases, 17 of which were malignant, and an IRB-approved retrospective chart review of 116 WL patients for comparison.
The average re-excision rate for SCOUT was 11.8% compared with 37% for WL, translating to 68% reduction in re-excision rates with SCOUT. The average specimen weight was 55g for the SCOUT cohort versus 63g for WL cohort, with an average margin width of 3.0mm for SCOUT versus 2.7mm for WL.
As part of this study, investigators also assessed surgical trainees’ ability to perform the SCOUT radar localization procedure. Residents were successfully able to localize the lesion in 25/26 cases (96%), demonstrating ease of use with the device.
Dr. Chu shares his perspectives on the radar localization system.
What prompted you to adopt SCOUT?
I learned about SCOUT from our SAVI Brachy account manager and it just clicked with me right away. We were using wire localization, a very old procedure, and it was time for a change. We were not interested in radioactive seed localization due to the stringent regulatory requirements. This was exactly what we needed.
What do you believe are the key clinical benefits of SCOUT?
The first key benefit is the reduction in re-excision rates and now we have the data to demonstrate it. Secondly, I can perform a better oncoplastic procedure. With a WL you are limited to following the path of the wire, with SCOUT I can use the guide to find the reflector signal and then plan my incision accordingly. I have so much more control. This leads to a much better cosmetic outcome for my patients.
