彩色多普勒超声在乳腺肿物良恶性鉴别诊断和乳腺癌分期中的临床研究

Clinical reasearch on color doppler ultrasound in diagnosis of benign and malignant breast lumps andassessing of TNM staging

目的:探讨分析临床使用彩色多普勒超声鉴别乳腺肿物良恶性和乳腺癌TNM分期的评估价值。方法:选取86例乳腺肿块患者,使用彩超判断肿块良恶性并与病理结果比对,同时对肿块的形态、边界、包膜、回声等彩超影像特征进行分析;恶性肿块应用彩超结合CDFI分级标准,评估TNM分期的准确度。结果:以病理检查结果为依据,彩超在良恶性肿块的检出率分别为90.63%和72.73%,良性肿块检出率高于恶性肿块(P<0.05);良恶性肿块在形态、边界、包膜和回声影像特征上存在统计学差异(P<0.05);恶性肿块的TNM分期越高,血流分级也越高。结论:彩色多普勒超声技术可以准确地鉴定乳腺肿块的良恶性,并且对良性肿块的检出率更高,在恶性肿块的TNM分期评估上也具有一定参考价值。

Objective:To evaluate the clinical value of color Doppler ultrasound(CDU)in diagnosis of benign and malignant breast lumps and TNM staging of breast cancer.Methods:Selected the 86 cases of breast lump patients,used CDU to determine the benign and malignant lumps and compared them with pathological results.Analyze the imaging of lump's shape,boundary,internal echo and diolame.Malignant lumps were given TNM stage to observe the diagnostic value of CDU.Results:Compared with pathological results,the relevance ratio of CDU in benign and malignant breast lumps were 90.63%and 72.73%,which means the rate of benign breast lumps was higher(P<0.05).There were statistical differences between the shape,boundary,internal echo and diolame of benign and malignant breast lumps.The higher the TNM staging of malignant lump,the higher the grade of blood flow.Conclusion:CDU can accurately identify the benign and malignant breast lumps,and the relevance ratio of benign lumps is higher,and it also has some reference value in the evaluation of TNM stage of malignant lumps.
