BACKGROUND: Wire-guided localization (WGL) has been the mainstay for localizing non-palpable breast lesions before excision. Due to its limitations, various wireless alternatives have been developed. In this prospective study, we evaluate the role of radiation-free wireless localization using the SAVI SCOUT® localization at a European centre. PATIENTS AND METHODS: This technique was evaluated in a prospective cohort of 20 patients. The evaluation focused on clinical and pathological parameters in addition to patient and physician acceptance. RESULTS: SAVI SCOUT reflectors (n=23) were deployed to localize 22 occult breast lesions and one axillary lymph node in 20 patients. The mean deployment duration was 5.6 min, with a mean distance from the lesion of 0.6 mm. The migration rate was 0% and the mean identification and retrieval time was 25.1 min. In patients undergoing therapeutic excision for malignancy (n=17), only one (5.9%) required reoperation for positive surgical margins. Radiologists and surgeons rated the technique as better than WGL and patient satisfaction was high. CONCLUSION: Our study demonstrates that wireless localization using SAVI SCOUT® is an effective and time-efficient alternative to WGL with excellent physician and patient acceptance. Copyright
