三阴性乳腺癌X线特征分析

目的:探讨三阴性乳腺癌的X线特征。方法:收集经手术病理证实为乳腺癌的202例患者资料，根据雌激素受体（ER）、孕激素受体（PR）和人表皮生长因子受体（HER-2）表达情况将其分为三阴性乳腺癌（TNBC）与非三阴性乳腺癌（NTNBC），比较两组病例腺体分型、病灶是否单发、肿块情况及有无钙化。结果:202例乳腺癌TNBC有34例，NTNBC有168例。两组病例肿块边缘及有无钙化差异有统计学意义(P均＜0.05)。腺体分型、是否单发、肿块的大小、肿块的形态、肿块的密度差异无统计学意义。结论:TNBC有一定特征，大多为单发肿块，与NTNBC相比肿块边缘更易表现为清晰光滑，钙化相对少见的征象。

Mammographic features of triple negative breast cancer

To analyze the X - ray findings of triple negative breast cancer. Methods：The results of 202 cases of breast cancer identified by postoperative pathology were collected,which distinguished to triple negative breast cancer（TNBC）and non - triple negative breast cancer（NTNBC）by immunohistochemologic receptor status of estrogen receptor（ER）,progesterone receptor（PR）and human epidermal growth factor receptor 2（HER - 2）. The re-sults of mammary gland type,mass＇s number,margin and calcification on mammograms were compared. Results：Of 202 cases breast cancer included 34 cases TNBC and 168 cases NTNBC,the differences between mass margins and calcification incidence were statistically significant（P ﹤ 0. 05）,and there were no statistically significant differences among mass＇s number,size,shape,density and mammary gland type（P ﹥ 0. 05）. Conclusion：TNBC shows merely a mass with indistinct margins and less calcifications than NTNBC.
