乳腺微小钙化灶定位切除的临床应用

目的探讨应用乳腺摄片结合立体定位系统对乳腺微小钙化灶进行细针定位外科切除术及B超定位金属“倒钩”选择切口的价值。方法对2000年5月至2006年11月收治的178例乳腺微小钙化灶患者行X线引导下细针定位外科切除活检术,其中62例经B超定位金属“倒钩”选择切口。结果全组178例患者中,发现乳腺癌58例（32．6％）,其中导管内癌32例（55．1％）,导管内癌伴间质浸润11例（19．0％）,浸润性导管癌15例（25．9％）,伴有淋巴结转移者4例。5年生存率100％。经B超定位选择切口患者较沿针道切除选择切口患者对术后乳腺外形的改变满意度高（P=0．022）。结论对乳腺微小钙化灶实施X线立体定位、B超定位选择切口的外科切除术是一种可靠安全的诊断方法。

Clinical application of localized biopsy on breast microcalcification

OBJECTIVE: To evaluate fine needle localized biopsy under mammography-guiding and skin incision selection by hookwire under ultrasound-guiding for patients with breast microcalcification. METHODS: Breast microcalcification of 178 patients treated from May 2000 to November 2006 were resected after localized with fine needle under X-ray mammography-guiding. Among them, 62 patients received the selection of hookwire under ultrasound-guiding. RESULTS: Breast cancer was detected in 58 patients (32.6%). Among them, 32 (55.1%) cases were carcinoma in situ, 11 (19.0%) intraductal carcinoma with early infiltration, 15 (25.9%) infiltrative ductal carcinoma, and 4 infiltrative ductal carcinoma with lymph node metastasis. The overall 5-year survival rate was 100%. Compared with that in needle guided group, the acceptable rate of cosmetic results was higher in hookwire group (P = 0.022). CONCLUSIONS: For breast microcalcification, mammography guided needle biopsy with ultrasound selected skin incision is an effective and accurate diagnostic method.
