【摘要】：目的观察三阴性乳腺癌(TNBC)与BI-RADS 4A类纤维腺瘤、腺病的超声表现。方法回顾性分析经病理证实的42例TNBC(TNBC组)、34例超声BI-RADS 4A类的纤维腺瘤(纤维腺瘤组)、36例BI-RADS 4A类的腺病(腺病组)的超声表现,并进行统计学分析。结果 TNBC组与纤维腺瘤组的年龄、病灶大小、形状、内部回声、边缘、BI-RADS分类差异有统计学意义(P均0.016 7);TNBC组与腺病组的年龄、肿块大小、边缘、与周边导管关系、BI-RADS分类差异有统计学意义(P均0.016 7);纤维腺瘤组与腺病组的形状差异有统计学意义(P0.016 7);3组的边界、声晕、后方回声、方位、钙化差异无统计学意义(P均0.05)。结论 TNBC乳腺癌多见于50岁以上女性,病灶多2 cm,表现为极低回声,不规则形,边界清晰,质硬,BI-RADS分类多4B及以上;超声BI-RADS 4A类的纤维腺瘤常呈分叶形或不规则形,边界清晰;超声BI-RADS 4A类的腺病常呈不规则形,垂直位生长时易与乳腺癌混淆。
[Abstract]:Objective to observe the ultrasonographic features of triple negative breast cancer (TNBC) and BI-RADS 4A fibroadenoma and adenopathy. Methods the ultrasonographic findings of 42 cases of TNBC (TNBC group) and 34 cases of BI-RADS type 4A fibroadenoma (fibroadenoma group) confirmed by pathology were retrospectively analyzed and analyzed statistically in 36 cases of BI-RADS type 4A adenopathy (adenopathy group). Results there were significant differences in age, lesion size, shape, internal echo and BI-RADS classification between TNBC group and fibroadenoma group (all P 0.016 7). There were significant differences in BI-RADS classification between fibroadenoma group and adenopathy group (P 0.016), but there was no significant difference in boundary, acoustical halo, posterior echo, azimuth and calcification between fibroadenoma group and adenopathy group (P0.0167). Conclusion TNBC breast cancer is more common in women over 50 years of age, with more than 2 cm of lesions, showing very low echo, irregular shape, clear boundary, more than 4B and more BI-RADS classification of BI-RADS, the fibroadenoma of BI-RADS 4A is usually lobular or irregular, and the boundary is clear. Ultrasound BI-RADS 4A adenopathy is often irregular and is easily confused with breast cancer when growing vertically.
