乳腺实性乳头状癌的超声特征

Ultrasonographic features of breast solid papillary carcinoma

目的:探讨乳腺实性乳头状癌(solid papillary carcinoma,SPC)的声像图特征。方法:回顾性分析23例SPC与45例浸润性导管癌(invasive ductal carcinoma,IDC)的声像图表现,对比分析SPC的声像图特征。结果:SPC平均发病年龄较IDC大(P<0.05)。SPC病灶在生长方位、形态、边界、边缘、后方回声、血供以及阻力指数方面与IDC相比差异有统计学意义(P<0.05)。相较于IDC,SPC更易表现出边界清晰、平行位生长、边缘呈分叶微小分叶状、后方回声增强、血供丰富且阻力指数较高等声像图特征。两者在钙化灶、淋巴结转移率等方面差异无统计学意义(P>0.05)。结论:乳腺SPC的声像图表现具有一定特征性,与乳腺常见恶性肿瘤相比差异有统计学意义。

Objective： This study aimed to investigate the ultrasonographic features of solid papillary carcinoma（SPC） of the breast. Methods： A retrospective analysis was made by collecting the ultrasonographic findings of 23 cases of SPC and 45 cases of invasive ductal carcinoma（IDC）, meanwhile, the sonographic features of SPC were compared and analyzed. Results： The average age of onset was higher in the patients with SPC than those with IDC（P0.05）. Furthermore, there were statistical differences in the comparison of growth orientation, shape, boundaries, margins, posterior acoustic features, blood supply, and resistance index between SPC and IDC（P0.05）. In relative to IDC, SPC showed evident sonographic features of more clear boundaries, parallel growth, microlobulated at the edge of the lesion, enhanced posterior echoes, abundant blood supply and higher resistance index. In addition, no obviously statistical difference was found in calcification and lymph node metastasis rate between them（P0.05）. Conclusion：The sonographic features of SPC of the breast have certain characteristics, which are significantly different from those of common malignant tumors of the breast.
