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(P<0.016 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。
Objective To compare ultrasonic manifestations of triple-negative breast cancer （TNBC）, BI-RADS category 4A atypical fibroadenoma and adenosis. Methods Ultrasonic findings of TNBC group （n=42）, BI-RADS 4A atypical fibroadenoma group （n=34） and adenosis group （n=36） were analyzed retrospectively, and statistical analysis was performed. Results There were statistically significant differences of age, tumor size, shape, echo, margin and BI-RADS category between TNBC group and fibroadenoma group （all P〈0.016 7）. There were statistically significant differences （all P〈0.016 7） of age, size, margin, peripheral duct changes, and BI-RADS category between TNBC group and adenosis group. There were statistically significant differences of shape between fibroadenoma group and adenosis group （P〈0.016 7）. There was no statistically significant difference of boundary, halo, posterior acoustic features, orientation, nor calcification among three groups （all P〉0.05）. Conclusion TNBC often occurs in women older than 50 years old, and the lesions usually demonstrate larger than 2 cm, very lower echo, and irregular shape with distinct margin. TNBC is usually associated with harder elastography feature, and is classified as more than BI-RADS 4B. Fibroadenoma classified as BI-RADS 4A is most likely to be a mass with lobulated or irregular shape with distinct margin. Adenosis classified as BI-RADS 4A often appears irregular and vertical orientation, which may be confused with breast cancer.
