【摘要】 目的探讨乳腺X线立体定位倒钩钢丝置入引导切取活检术(stereotacticmammographyneedlelocalizedbiopsy,SNLB)对乳腺隐匿病灶(nonpalpablebreastlesion,NPBL)的临床应用价值。方法回顾性分析37例行SNLB活检病例,所有病例均为临床触诊阴性,X线片上发现可疑改变但不能定性的病灶,将活检标本病理结果与X线表现进行对照。结果乳腺X线片上表现为细沙样簇状钙化18例;孤立的结节8例:局限性致密或结构紊乱7例;放射状毛刺影4例。SNLB活检组织标本病理结果中良性病变26例、恶性病变11例,其中包括导管原位癌4例。结论SNLB可准确诊断NPBL的性质,提高早期乳腺癌的检出率。更多还原

【Abstract】 Objective discussing the clinical values of the application of SNLB to NPBL.Methods Retrospective analysis of 37 cases with breast lesion,which were nonpalpable clinically but could be detected by mammography,all cases underwent SNLB.We compare the pathologic diagnosis of the biopsy specimen with Mammographic features.Results Among 37 cases various features could be found in their X-ray appearances:Cluster microcalcifications in 18 cases,nodular lesion in 8cases,architecture distortion in 7cases,spicules in 4 cases.Pathologic diagnosis of biopsy specimen were as follows:26 benign lesions,11 malignant lesions including 5 cases of in ductal carcinoma in sltu.Conclusion SNLB can diagnose NPBL exactly and improve the rate of the detection of early-stage breast cancer.
