Abstract

BACKGROUND: The standard localization of non-palpable breast masses is wire/needle localization (WL). Newer technologies have evolved, allowing more efficient scheduling and improving surgeon and patient experiences. These include Radioactive Seed, MagSeed®, and SAVI Scout® (SS). We adopted SS at our program in July of 2017. We are reporting our experience comparing SAVI Scout® with needle localization.

STUDY DESIGN: This is a retrospective study comparing SS and wire localization techniques for the excision of both benign and malignant lesions. Chart reviews of localized patients between 7/1/2017 and 6/30/2019, recording the age of the patient, date of procedure, localization method, pathology of lesion postexcision, number and status of margins, guidance method (mammogram vs. ultrasound), specimen size, and distance of reflector from biopsy clip, were completed to compare these localization methods with the aim of asserting their equality.

RESULTS: There were 48 wire and 64 SS localized excisions. Successful lesion excision was achieved in 100% of cases for both techniques. There were 1 SS and 4 WL re-excisions for margin clearance not reaching statistical significance. 51 additional margins were obtained in the SS cases compared to 36 margins in the WL cases without a statistically significant difference.

CONCLUSIONS: 1- Both SS and WL achieved 100% excision of targeted lesions 2- SS localization was successfully implemented, offering more convenience for patients and providers 3- More re-excisions in the WL group as compared to the SS group did not reach statistical significance and requires further investigation 4- A prospective controlled trial comparing the different localization techniques can address questions related to effectiveness, cost, patient and provider experiences.
