A newly adapted clip system for intramammary marking during ultrasound-guided core needle biopsy for suspicion of breast cancer is described and evaluated here. Fifty patients with suspicion of breast cancer (cT2) had ultrasound-guided core needle biopsy using a newly adapted clip marker system (HistoCore™ and O-Twist Marker™). Subsequently, ultrasound follow-up and tomosynthesis scans were done to determine the location of the marker clips. No dislocation of the marker clip was detected on ultrasound in 45 of 50 patients (90 %), and 5 patients (10 %) had a maximum dislocation of 5 mm along the x-, y- or z-axis. Tomosynthesis scans demonstrated precise placement without dislocation of the clip markers in 48 patients (96 %); 2 patients (4 %) had a maximum dislocation of 3 mm along the x-, y- or z-axis. The newly developed clip marker system, a combination of a single-use breast biopsy needle and a precise, length-adapted intramammary marker clip, represents a further improvement in oncological therapy. This is of particular importance for patients requiring subsequent neoadjuvant chemotherapy, as in cases with complete tumour remission, there is no target point for preoperative, ultrasound-guided wire marking.
本文介绍并评估了一种新改良的用于在超声引导下对疑似乳腺癌患者进行乳腺内标记的夹钳系统。50例疑似乳腺癌（cT2）患者在超声引导下使用新改良的夹钳标记系统（HistoCore™和O-Twist Marker™）进行了粗针活检。随后，进行超声随访和断层合成扫描以确定标记夹的位置。50例患者中有45例（90%）在超声检查中未检测到标记夹移位，5例患者（10%）在x、y或z轴上的最大移位为5毫米。断层合成扫描显示48例患者（96%）的夹钳标记放置精确且无移位；2例患者（4%）在x、y或z轴上的最大移位为3毫米。新开发的夹钳标记系统是一次性使用的乳腺活检针与精确的、长度适配的乳腺内标记夹的组合，代表了肿瘤治疗的进一步改进。这对于需要后续新辅助化疗的患者尤为重要，因为在肿瘤完全缓解的情况下，术前超声引导下的导丝标记没有靶点。
