SCOUT® radar localization of non-palpable breast carcinomas versus traditional wire-based localization: a single center retrospective comparison

Year: 2025

Type: article

Abstract: PURPOSE: Breast-conserving therapy requires a secure method to localize non-palpable lesions. The traditional and simple metal wire localization (WL) is challenged by more advanced and costly techniques that may have several advantages. We report the first European direct comparison between WL and SCOUT® Radar Localization (RL) comparing oncological and logistical benefits of implementing the new method in the treatment of non-palpable breast carcinomas including in situ lesions. METHODS: We retrospectively analyzed 150 breast cancer surgeries performed immediately before and after WL was replaced by RL in our unit. The last 50 wire-guided surgeries were compared to the initial 50 radar-guided surgeries (cohort I, implementation phase) and to the subsequent 50 radar-guided surgeries (cohort II, routine phase). RESULTS: All lesions and markers were successfully removed in all groups. No procedure-specific complications were registered. Of the 50 patients in the WL group, 8 % needed redo surgery due to positive margins, compared to 4 % in the RL groups (not statistically different). The histological margin was similar between the groups. The median time consumption during surgery was reduced by 26.5 min after establishing the radar localization method (p = 0.022). The resected tissue corresponded better with the marked area in the breast in the RL group (p = 0.026), as evaluated by a more central placement of the marker. CONCLUSIONS: Radar localization of breast carcinomas is safe for women with non-palpable breast carcinomas including in situ lesions. The method reduces time consumption in the operating room and may give better surgical precision.
