计算机定位活检与摄影对早期乳腺癌诊断的比较研究

A comparative study of digital mammography-guided biopsy and mammography in diagnosis of early stage breast cancer

目的评价并比较计算机定位活检与摄影对早期乳腺癌诊断的价值。方法2001年11月至2002年9月乳腺数字化摄影2850例,其中直径≤2.0 cm病灶156处(148例患者)。随机对68处行计算机定位活检,以手术病理结果和随访结果为金标准,比较计算机活检法与摄影法对早期乳腺癌诊断的一致性。结果活检明显优于摄影(P<0.05)。结论计算机活检法对早期乳癌诊断有很大实用价值。

Objective To evaluate and compare the diagnostic value of digital mammography-guided biopsy with mammography for early-stage breast cancer. Methods 68 of 156 foci（from 148 cases） with diameter≤ 2.0 cm from 2850 mammographic cases during Nov. 2001 and Sep. 2002, were urdestaken mammography-guided biopsy and then compared the coherence of the biopsy and mammographic results with the pathology. Results The obviously accuracy of mammography-guided biopsy is obviously superior to the mammography （P 〈 0.05 ）. Conclusions Digital mammography-guided biopsy possesses great clinical practical value to the diagnosis of early stage breast cancer.
