超声恶性征像对三阴性乳腺癌的鉴别诊断价值

目的探讨超声恶性征像对三阴性乳腺癌的鉴别诊断价值。方法选取2008年2月至2013年11月在我院进行手术治疗的58例三阴性乳腺癌患者设为三阴性组,另选取同期在我院进行手术治疗的58例非三阴性型的乳腺癌患者设为非三阴性组。比较两组患者的超声征像。结果两组患者的年龄、癌肿大小、病理学类型及组织学分级等情况相比较差异均无统计学意义（P〉0.05）。两组患者的超声恶性征像在边界不清、存在毛刺征或高回声晕征、病灶内有微小钙化、血流分级为2~3级、腋窝淋巴结转移等方面相比较差异均有统计学意义（P〈0.05）。两组患者在后方回声衰减、纵横比≥1、血流阻力指数≥0.7等方面相比较差异均无统计学意义（P〉0.05）。结论肿块边缘不清、存在边缘毛刺征或高回声晕、病灶内发现微小钙化、血流分级为2~3级、腋窝淋巴结转移等超声恶性征像对于诊断三阴性乳腺癌具有极高的临床价值。

Value of ultrasonography in differential diagnosis of malignant features of triple-negative breast cancer

Objective To evaluate the value of ultrasonography in the diagnosing malignant triple negative breast cancer identification. Methods From February 2008 to November 2013 in our hospital for surgical treatment of 58 cases diagnosed as triple-negative breast cancer were Selected to triple-negative groups. Also, the same period in our hospital for surgical treatment of 58 cases diagnosed as non-triple negative type of breast cancer were Selected to a non-triple negative group. Ultrasonic signs of the two groups of patients were compared. Results The age, tumor size, pathological type and histological grading are compared between two groups of patients, The difference was not statistically significant（P〉0.05）. Two groups of patients ultrasonic malignant signs at unclear border,spiculation or hyperechoic halo sign, microcalcifications within the lesions, blood flow signal grade 2~3, axillary lymph node metastases compared with other aspects, the differences were statistically significant（P〈0.05）. Two groups of patients in the rear echo attenuation, aspect ratio≥1, vascular resistanceindex≥0.7, etc. compared the difference was not statistically significant（P〈0.05）.Conclusion The tumor edge is unclear, there is a burr or hyperechoic halo sign was found microcalcifications within the lesions, blood flow signal grade 2~3, axillary lymph node metastasis of malignant ultrasound signs for triple negative breast cancer diagnosis with high clinical value.
