Reflector-guided Localization of Non-palpable Breast Lesions: The First Reported European Evaluation of the SAVI SCOUT® System

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.
