超声诊断分级系统在非触摸性乳腺疾病中应用的评价

Evaluation of diagnostic classification of ultrasonography in nonpalpable breast lesions

目的:评价非触摸性乳腺疾病(NPBLs)超声诊断分级的应用。方法:选取158例临床触诊阴性并接受超声体表定位患者的影像学资料,采用欧洲分级系统进行分级,并与切取活检后的病理结果进行比较。结果:158例患者病理确诊为良性124例,恶性34例。病理确诊为乳腺癌的34例患者中,超声诊断为正常/良性的3例(8.8%),交界性病变2例(5.9%),可疑/符合恶性29例(85.3%),乳腺X线诊断为正常/良性12例(35.3%),交界性9例(26.5%),可疑/符合恶性13例(38.2%)。超声的敏感性显著高于乳腺X线的敏感性(94.1%vs38.2%,P=0.000)。超声诊断的特异性和乳腺X线差异无统计学意义(96.0%vs91.1%,P=0.118)。结论:对于NPBLs的影像学诊断,超声起到较好的诊断作用。

OBJECTIVE： To evaluate the value of diagnostic classification and skin-marker localization of ultrasonography in no- palpable breast lesions（NPBLs）. METHODS： A total of 158 patients with NPBLs were classified by european system for breast imaging and localized to surgical excision with skin-marker by ul trasonography. Clinical data were compared with pathological findings. RESULTS： There were 124 benign lesions and 34 malignant lesions in the final pathological diagnosis. In 34 malignant lesions, there was benign lesions 3 （ 8. 8 % ）, broderline lesions 2 （ 5.9 % ） diagnosed by ultra sonography, which were 12 （35.3%）, 9 （26.5%） and 13（38.2%） respectively, diagnosed by x-ray, malignant lesions 29 dUltrasonograph appeared to be more sensitive than mammography （94.1% vs 38.2% ,P=0. 000）. There was no significant difference in specificity between them （96. 0% 91.1%, P= 0. 118）. CONCLUSIONS： Ultrasound assessment improves breast cancer detection in women with NPBLs.
