摘　　要：目的研究年龄联合剪切波弹性成像(SWE)对乳腺影像报告数据系统(BI-RADS)4a类乳腺肿物的诊断价值。方法对82例罹患乳腺肿物的患者共87个分类为BI-RADS 4a类的肿物进行超声SWE检查,测量肿物内部最大杨氏模量值(Emax)以及肿物周边2 mm Emax,并记录患者年龄。以病理结果为“金标准”绘制受试者工作特征(ROC)曲线,分别获取年龄、肿物内部Emax以及肿物周边2 mm Emax的最佳截断值,并在此基础上,分别绘制年龄联合肿物内部Emax与年龄联合肿物周边2 mm Emax的ROC曲线,以分析两项联合指标的诊断效能。结果87个BI-RADS 4a类肿物的病理诊断结果为良性57个、恶性30个。年龄、肿物内部Emax、肿物周边2 mm Emax均对乳腺肿物有一定的预测价值,其中年龄最佳截断值为50.5岁,肿物内部Emax最佳截断值为119.490 kPa,肿物周边2 mm Emax最佳截断值为133.550 kPa。年龄联合肿物内部Emax的曲线下面积(AUC)为0.756,标准误(SE)为0.055(P<0.001),诊断灵敏度为0.575,特异度为0.937,诊断指数最大为0.512;年龄联合肿物周边2 mm Emax的AUC为0.794,SE为0.051(P<0.001),诊断灵敏度为0.650,特异度为0.937,诊断指数最大为0.587。结论年龄联合肿物内部Emax与年龄联合肿物周边2 mm Emax均对BI-RADS 4a类乳腺肿物有一定的诊断价值,且能够减少良性肿物不必要的手术或穿刺活检。Objective To study the diagnostic value of age combined with shear wave elastography(SWE)in breast imaging reporting and data system(BI-RADS)4a breast tumor.Methods A total of 87 BI-RADS 4a breast tumor in 82 patients with breast tumor were examined by ultrasound SWE.The maximum Young's modulus(Emax)inside the tumor and 2 mm Emax around the tumor were measured,and the age of the patients was recorded.The receiver operating characteristic(ROC)curve was drawn with the pathological results as the"gold standard".The optimal cut-off values of age,Emax inside the tumor and 2 mm Emax around the tumor were obtained respectively,on this basis,the ROC curves of age combined with Emax inside the tumor and age combined with 2 mm Emax around the tumor were drawn respectively,the diagnostic efficacy of the two combined indicators were analyzed.Results Among the 87 BI-RADS 4a tumors,57 were benign and 30 were malignant.Age,Emax inside the tumor,and 2 mm Emax around the tumor had certain predictive value of breast tumor,the optimal cut-off value of age was 50.5 years old,the optimal cut-off value of Emax inside the tumor was 119.490 kPa,and the optimal cut-off value of 2 mm Emax around the tumor was 133.550 kPa.The area under the curve(AUC)of age combined with Emax inside the tumor was 0.756,the standard error(SE)was 0.055(P<0.001),the diagnostic sensitivity was 0.575,the specificity was 0.937,and the maximum diagnostic index was 0.512;the AUC of age combined with 2 mm Emax around the tumor was 0.794,SE was 0.051(P<0.001),the diagnostic sensitivity was 0.650,the specificity was 0.937,and the maximum diagnostic index was 0.587.Conclusion Age combined with Emax inside the tumor and age combined with 2 mm Emax around the tumor have certain diagnostic value for BI-RADS 4a breast tumors,and can reduce unnecessary surgery or biopsy of benign tumors.
