三阴性乳腺癌超声特征

Sonographic feathers of triple-negative breast cancer

目的：探讨三阴性乳腺癌超声声像图特征。方法回顾性分析129例女性浸润性乳腺癌患者的超声及病理资料，根据免疫组化结果分为43例三阴性乳腺癌（TNBC）和86例非三阴性乳腺癌（non-TNBC），比较两组超声图像的差别。结果 TNBC 与 non-TNBC 比较，肿瘤形态规整、周边高回声晕、钙化、肿块后方回声衰减、2~3级血流和阻力指数≥0.7比较差异有统计学意义（P 〈0.05）；边界清晰、纵横比≤1、毛刺征、腋窝淋巴结转移率比较差异未见统计学意义（P 〉0.05）。结论 TNBC 肿瘤形态规整，缺少周边高回声晕及实质钙化，后方回声增强，血流不丰富。

Objective To investigate the sonographic features of triple-negative breast cancer （TNBC）. Methods One hundred and twenty-nine famale invasive breast cancer were divided into triple-negative breast cancer（ TNBC） group（ n = 43） and non-triple-negative breast cancer（ non-TNBC） group （n = 86）according to immunohistochemistry. Ultrasonic and pathological characteristics were studied and compared. Results There were significant differences between TNBC group and non-TNBC group in regular morphology, hyper halo echo, calcification, posterior echo attenuation, blood stream grade 2 - 3 and RI≥0. 7（P 〈 0. 05）. There were no significant differences in distinct boundary,D / W≤1, burrs margin and lymph node metastasis rate（ P 〉 0. 05） . Conclusions TNBC mass are regular, lack of hyper halo echo, calcification and posterior echo attenuation. Blood stream grade 2 - 3 and RI≥0. 7 are fewer too.
