乳腺叶状肿瘤良恶性的超声图像特点分析

Ultrasound Image Analysis of Benign and Malignant Breast Phyllodes Tumors

目的:分析以超声技术检验乳腺叶状肿瘤良恶性的声像图特点差异。方法:此次选择2015年1月-2019年1月笔者所在医院收治乳腺叶状肿瘤患者80例为研究对象,分析肿瘤良恶性的病理学表现差异,对比良恶性叶状肿瘤二维灰阶超声图像,比较彩色多普勒血流图像。结果:80例患者均为单侧单发病灶,其中35例为良性肿瘤,26例为交界性肿瘤,19例为恶性肿瘤。经检验分析发现,三种肿瘤情况在肿瘤形状、大小、边缘、后方回声、钙化水平方面差异无统计学意义(P>0.05),但良性肿瘤边界清晰度、内部均匀回声占比均明显高于恶性肿瘤及交界性肿瘤(P<0.05)。同时交界性肿瘤边界清晰度、内部均匀回声占比又较恶性肿瘤占比更高(P<0.05)。经彩色多普勒超声检验血流情况发现,三者血流信号等级差异无统计学意义(P>0.05)。结论:乳腺叶状肿瘤超声技术检验准确度较高,能够根据肿瘤边界清晰程度、内部回声情况等判定良恶性质,值得临床应用与推广。

Objective:To analyze the difference of sonographic features of benign and malignant tumors in breast phyllodes tumors by ultrasound technique.Method:From January 2015 to January 2019,80 patients with breast phyllodes tumors in our hospital were selected as subjects.The pathological findings of benign and malignant tumors were analyzed.Two-dimensional gray-scale ultrasound images of benign and malignant phyllodes tumors were compared.As well as compared the color Doppler blood flow images.Result:Eighty patients were unilateral single lesions,of which 35 were benign tumors,26 were borderline tumors,and 19 were malignant tumors.According to the test analysis,there was no significant difference in tumor shape,size,margin,posterior echo and calcification level(P>0.05),but the boundary resolution and internal uniform echo ratio of benign tumors were significantly higher than malignant tumors and borderline tumors(P<0.05).At the same time,the boundary definition and internal uniform echo ratio of borderline tumors were higher than those of malignant tumors(P<0.05).Blood flow imaging by color Doppler ultrasound revealed that there was no significant difference in blood flow signal levels among the three groups(P>0.05).Conclusion:The accuracy of ultrasound technique in breast phyllodes tumors is high.It can be judged according to the degree of tumor boundary and internal echo,which is worthy of clinical application and promotion.
