讨论钼靶三维立体钩丝定位对乳腺钙化病灶切除术前的指导意义，以期为隐匿性乳腺癌的早期诊断及病灶精准切除提供帮助。

收集2015年1月—2016年6月期间我院收治的临床触诊阴性、X线钼靶发现不同形态钙化灶的患者32例，行钼靶三维钩丝定位后手术切除病灶，标本再次行X线摄片，确定病灶切除完整性，送病理科，根据快速病理结果选择手术方式。

32例患者中，钩丝头均距离病灶<2 cm，定位准确。恶性11例，其中导管原位癌6例，浸润性导管癌3例，浸润性小叶癌2例；良性病变21例：乳腺增生伴钙化16例，纤维腺瘤伴钙化3例，不典型增生2例。根据病理结果选用不同手术方式。

钼靶三维钩丝定位可有效提高早期乳腺癌的诊断率，指导外科精准切除病灶，减少了正常乳腺组织的误切，提高了患者生活质量。

The significance of the three-dimensional hook wire of molybdenum target in guiding the excision of calcification lesion of the breastis studied. And its clinical role in terms of improving early diagnosis of hard-to-detect breast tumor and locating the accurate resection of the lesion is highly anticipated.

32 cases with negative clinical examination and different forms of calcification founded by X-ray molybdenum target between January 2015—June 2016 in our hospital were collected. These patients immediately received the resection of the lesion after the three-dimensional wire hook line of molybdenum target positioning, followed by the X-ray take to determine the lesion has completely been removed. The specimens were sent for pathological examination to decide the following operation method.

In all of the 32 cases, malignant lesions were detected in 11 cases including:ductal carcinoma in situ 6 cases, infiltrating ductal carcinoma 3 cases, invasive lobular carcinoma 2 cases; benign lesions in 21 cases: hyperplasia of mammary glands with calcification 16 cases, fibroadenoma with calcification 3 cases, dysplasia 2 cases. It is found that the distance between the hook wire and lesions <2 cm, brings out the best positioning.

Molybdenum target three dimension hook wire of localization can significantly improve the diagnosis of early breast cancer, provide guidance for surgical resection of lesions, reduce unnecessary cut of normal breast tissues and improve the life quality of patients.
