超声弹性成像联合乳腺影像报告和数据系统(BI-RADS)分类诊断非肿块型乳腺癌

Ultrasonic elastography combined with breast imaging reporting and date system(BI-RADS)classification in diagnosis of nonpalpable breast cancer

目的探讨超声弹性成像(UE)技术联合乳腺影像报告和数据系统(BI-RADS)分类对非肿块型乳腺癌的诊断价值。方法回顾性分析48例经二维超声及UE诊断、并经病理学证实的局灶性非肿块型乳腺病变患者(共53个病灶),以手术或穿刺活检病理结果作为金标准,评价超声弹性技术、BI-RADS分类及二者联合诊断非肿块型乳腺癌的价值。结果53个病灶中,良性21个,恶性32个。UE诊断敏感度、特异度、准确率分别为68.75%、71.43%和69.81%;BI-RADS分类诊断敏感度、特异度和准确率分别为62.50%、66.67%和64.15%(P均>0.05);UE联合BI-RADS分类的诊断敏感度、特异度、准确率分别为81.25%、80.95%和81.13%,均高于单一UE或BI-RADS分类(P均<0.05)。结论UE联合BI-RADS分类能提高诊断非肿块型乳腺癌的敏感度、特异度和准确率。

Objective To explore the value of ultrasonic elastography(UE)combined with breast imaging reporting and date system(BI-RADS)classification in diagnosis of nonpalpable breast cancer.Methods Data of 48 patients with 53 focal non-lump breast lesions diagnosed with two-dimensional ultrasound and UE and proved pathologically were retrospectively analyzed.Taken surgical or biopsy pathologic results as the golden standards,the value of UE,BI-RADS classification and the combination of these 2 methods for diagnosing nonpalpable breast cancer were evaluated.Results Among 53 lesions,21 were benign and 32 were malignant.The sensitivity,specificity and accuracy of UE was 68.75%,71.43%and 69.81%,of BI-RADS classification was 62.50%,66.67%and 64.15%,respectively(all P>0.05).The sensitivity,specificity and accuracy of UE combined with BI-RADS classification was 81.25%,80.95%and 81.13%,all higher than those of UE or BI-RADS classification alone(all P<0.05).Conclusion UE combined with BI-RADS classification could improve the sensitivity,specificity and accuracy of diagnosis of non-lump breast cancer.
