X线立体穿刺钢丝标记定位对无体征乳癌的诊断价值

目的 探讨X线立体穿刺钢丝标记定位在无临床体征的早期乳癌中的诊断价值。方法 对29例钼靶X片上有可疑病灶而无任何临床体征的患者，在X线立体定位下穿刺病灶并用金属导丝标记，标记后根据导丝位置切除病灶，并进行快速冰冻活检，明确诊断。结果 29例中9例（31．0％）为癌，20例（69．0％）良性。冰冻切片病理检查与术后石蜡报告结果一致。结论 X线立体穿刺钢丝标记定位活检技术解决了乳腺微小病灶活检术中精确定位的难题，对无临床体征的早期乳癌诊断准确、可靠、实用。

Diagnostic value of needle stereotaction marking by steel wire unde r mammography for nonpalpable breast carcinoma

Objective To explore the diagnostic value of needle stereotaction marking by steel wire(NSMSW) under mammography for nonpalpable early stage breast carcinoma (BC). Methods 29 patients with nonpalpable breast lesions were performed NSMSW under mammography,and the lesions were removed for biopsy to make the diagnosis. Results Nine patients(31.0%) were definited as early stage BC and twenty(69.0%) benign disease.The pathologic results in freezing sections and in parafin sections were the same. Conclusions NSMSW under mammography can resolve the problem of accurate location of nonpalpable breast lesions during operation .It is a credible, useful and practical method for diagnosis of nonpalpable early stage BC.
