- Abstract
<bold>Background: </bold>Breast cancer is the most commonly diagnosed noncutaneous malignancy and remains the second leading cause of cancer deaths in women. The Savi Scout (Cianna Medical, Merit Medical Systems, Inc. South Jordan, UT) is a wireless, nonradioactive, wave reflection implant system that enables surgeons to remove targeted breast lesions. Our study aims to be the largest comparison of wire and Savi Scout localization techniques for positive margin, complication, and reoperation rates.<bold>Methods: </bold>Single-institution retrospective review of 512 patients that had Savi Scout Surgical Guidance System breast lesion biopsy or wire localized breast biopsy from May 2017 to December 2018. A RedCaps database was created and reviewed for outcomes.<bold>Results: </bold>For 320 Savi scout patients, margins were positive or less than 1 mm in 18 cases (5.6%). 17 (5.3%) patients required reoperation. Surgical site occurrence was found in 7 (2.1%) patients, and 2 patients required intervention (0.6%). For 175 wire localization patients, margins were positive or less than 1 mm in 24 patients, and all required reoperation (13.7%). A surgical site occurrence was found in 13 (7.4%) patients and 5 patients required intervention (2.8%).<bold>Discussion: </bold>In our series, the Savi Scout localization system resulted in a lower rate of positive margins, reoperation, and surgical site occurrence. These data suggest that Savi Scout localization is a reasonable replacement to wire localization for breast lesions and might produce superior results.
