33例三阴乳腺浸润性导管癌声像图特征分析

Imaging Features of Triple Negative Invasive Ductal Carcinoma of Breast in 33 Cases

目的分析三阴乳腺浸润性导管癌声像图特征,提高术前对此类患者认识水平。方法分析33例经外科术后病理、免疫组化确诊的三阴乳腺浸润性导管癌声像图,并与同期247例非三阴乳腺浸润性导管癌声像图比较分析。结果三阴乳腺浸润性导管癌患者声像图以边缘光滑、后方回声稍增强、内部少见微钙化为主要特征,腋窝常见淋巴结转移。结论三阴乳腺浸润性导管癌大多不具有乳腺癌典型声像图特征,同侧腋窝转移淋巴结较多见,了解这些特征可为临床判断预后及制定治疗方案提供一定参考信息。

Objective To improve the awareness level of patients before surgery by analyzing the sonographic features of triple negative breast invasive ductal carcinoma. Methods The ultrasonogram of 33 patients with triple negative breast invasive ductal carcinoma confirmed by postoperative pathology and immunohistochemical results were analysed and compared with 247 cases without triple negative breast invasive ductal carcinoma in the same period. Results The main imaging features of triple negative invasive ductal carcinoma were as followed： smooth edge, slightly enhanced rear echo and low incidence of inner microcalcification; lymph node metastases were found in fossa axillaris. Conclusions Most triple negative invasive ductal carcinomas do not have the typical imaging features of breast carcinoma, and metastatic lymph nodes located at the ipsilateral levels more frequent. Understanding of those characteristics can provide referenced information for prognosis and treatment programs in clinic.
