Many methods have been developed for localizing non-palpable breast lesions. This study investigated the success rate and surgical results of the magnetic seed (Magseed) and radiofrequency identification (RFID) method, which are relatively new compared to standard wire-guided localizations.
20 simulation (10 Magseed, 10 RFID) models were created using turkey breasts and raisins. Raisins containing magnetic seed and RFID tags were placed on the turkey breast. Sentimag® probe was used for the Magseed group, and Faxitron LOCalizer™ System device was used in the RFID group. Both methods were evaluated in terms of accuracy in detecting breast lesion localization, operation times, excised tissue weights, total resection volume, surgical margin negativity, and re-excision rates.
Lesion localization success in both techniques was 100%. While procedure times were statistically significantly shorter in the Magseed group, incision lengths were shorter in the RFID group (P = 0.013, P = 0.007, respectively). No statistically significant difference was found between the groups for the weight of the removed parts, total resection volume, and surgical margin distance (P > 0.05).
In this feasibility study, it was concluded that neither the RFID nor Magseed methods had a significant advantage over each other, in terms of localization detection and surgical margin negativity, and both methods could be used successfully for localization.
已经开发出许多用于定位不可触及的乳腺病变的方法。与标准导丝定位相比，本研究调查了磁性种子（Magseed）和射频识别（RFID）方法的成功率和手术结果，这两种方法相对较新。
使用火鸡胸脯和葡萄干创建了 20 个模拟（10 个 Magseed，10 个 RFID）模型。将含有磁性种子和 RFID 标签的葡萄干放在火鸡胸脯上。Magseed 组使用 Sentimag®探头，RFID 组使用 Faxitron LOCalizer™系统设备。两种方法均评估了检测乳腺病变定位的准确性、手术时间、切除组织重量、总切除体积、手术切缘阴性和再次切除率。
两种技术的病变定位成功率均为 100%。虽然 Magseed 组的手术时间明显缩短，但 RFID 组的切口长度较短（P=0.013，P=0.007）。两组切除部分的重量、总切除体积和手术切缘距离无统计学差异（P>0.05）。
在这项可行性研究中，Magseed 和 RFID 两种方法在定位检测和手术切缘阴性方面均无明显优势，两种方法均可成功用于定位。
