Accurate pre-operative localization of nonpalpable lesions plays a pivotal role in guiding breast-conserving surgery (BCS). In this multicenter feasibility study, nonpalpable breast lesions were localized using a handheld magnetic probe (TAKUMI) and a magnetic marker (Guiding-Marker System®). The magnetic marker was preoperatively placed within the target lesion under ultrasound or stereo-guidance. Additionally, a dye was injected subcutaneously to indicate the extent of the tumor excision. Surgeons checked for the marker within the lesion using a magnetic probe. The magnetic probe could detect the guiding marker and accurately localize the target lesion intraoperatively. All patients with breast cancer underwent wide excision with a safety margin of ≥5 mm. The presence of the guiding-marker within the resected specimen was the primary outcome and the pathological margin status and re-excision rate were the secondary outcomes. Eighty-seven patients with nonpalpable lesions who underwent BCS, from January to March of 2019 and from January to July of 2020, were recruited. The magnetic marker was detected in all resected specimens. The surgical margin was positive only in 5/82 (6.1%) patients; these patients underwent re-excision. This feasibility study demonstrated that the magnetic guiding localization system is useful for the detection and excision of nonpalpable breast lesions.

Purpose: To compare the positive margin rates for women with nonpalpable breast tumors whom had wire localization compared to radioactive seed localization in a small community hospital.Introduction: Wire localized (WL) breast biopsies have been performed on patients with nonpalpable breast lesions for many years. Radioactive seed localization (RSL) offers advantages of patient comfort and scheduling convenience.There is an extensive literature from large centers regarding the RSL technique. Little is known whether physicians performing these procedures in smaller community hospitals can achieve comparable negative margin rates as those performed with wire localization.Methods: The thirty-six patients who underwent wire localized breast conserving surgery between September 18, 2013 and December 10, 2014, were compared to the 48 radioactive seed localization patients resected between February 12, 2014 and December 18, 2014. The primary objective was to determine if the introduction of the radioactive seed localization technique significantly changed the positive margin rate.Results: Two of 36 wire localized breast biopsied patients had positive margins, compared to 5 of 48 radioactive seed localization patients, a difference which is not statistically different. The specimen weight was larger for the patients treated with the RSL technique. There was a trend toward a higher positive margin rate with older patients.Conclusion: The positive margin rate was similar between the wire localized and radioactive seed localized patients, and comparable to those in the published literature.
