全数字化俯卧式X 线立体钢丝定位术在乳腺微钙化病灶中的应用价值*

目的:探讨X 线立体定位钢丝引导切取活检术（SWLB）对乳腺微钙化病灶的临床应用价值。方法:回顾性分析2007年5 月至2008年5 月南方医科大学附属深圳妇幼保健院45例行SWLB 活检的乳腺隐匿性病变，所有病例均为临床触诊阴性而乳腺X 线摄影发现微钙化病灶，将活检标本病理结果与X 线表现进行对照。结果:45例SWLB 活检组织标本病理结果中恶性病变13例（28.9%），其中包括导管原位癌3 例（23.1%），导管原位癌伴微浸润4例（30.8%），浸润性导管癌5 例（38.5%），导管内乳头状癌1 例（7.7%）；良性病变32例（71.1%），其中包括导管上皮重度非典型增生2 例（6.3%）。 结论:SWLB 可准确引导切检临床阴性的乳腺微钙化病灶，明确乳腺微钙化的性质，提高早期乳腺癌的检出率。 

Value of Steel Wire Implantation with Prone Table Stereotactic Digital Mammography in the Detection of Microcalcification of the Breast

Objective:To explore the clinical value of stereotactic wire-localized biopsy(SWLB)in digital mammography in the detection of microcalcification of the breast.Methods:A total of 45 patients with nonpalpable breast lesions which were positive for microcalcification by mammography but could not be detected clinically underwent SWLB.Their mammography fndings were analyzed in detail with pathology.Results:Among the 45 cases,13 cases(28.9%)had malignant lesions including ductal carcinoma in situ in 3 cases (20.1%),ductal carcinoma in situ with microinvasion in 4 cases(30.8%),invasive ductal carcinoma in 5 cases (38.5%)and intraductal papillary carcinoma in 1 case(7.7%).Thirty-two cases(71.1%)had benign lesions,2 cases(6.3%)of which were severe atypical hyperplasia.Conclusion:SWLB can accurately guide the surgical excision of nonpalpable breast microcalcification lesions and diagnose microcalcifications exactly,which is helpful for increasing the detection rate of eady-stage breast cancer.
