超声结合数字乳腺三维断层摄影在乳腺癌诊断中的应用

摘要

Objective To compare the diagnostic accuracy of US and DBT plus US in the assessment of breast cancer. Method 102 patients who had breast lesions were selected. US and US plus DBT were used to estimate the breast lesions respectively. Pathological diagnoses were considered as golden standard. Result The AUC of ROC for US alone was 0. 821, while for US plus DBT it was increased to 0. 941, with statistically significant differences (P=0. 001). The diagnostic accuracy was higher in subgroup with age>50, subgroup with size≤2cm and subgroup with ACR3+ACR4 breast density by using US plus DBT than by using US alone, with statistically significant differ-ences, P<0. 05. Conclusion The diagnostic accuracy of breast cancer was improved to some extent by using DBT plus US than by using US alone.%目的：比较超声( ultrasound,US)结合数字乳腺三维断层摄影( digital breast tomosynthesis,DBT)与单独超声诊断乳腺癌的准确度。方法选择有乳腺病变患者102例,分别对US、US结合DBT进行独立诊断,评价两者诊断乳腺癌的准确度。结果 US、US结合DBT诊断乳腺癌的受试者工作特征( receiver operat-ing characteristic curve,ROC)曲线下面积分别为0.821及0.941,差异有显著性(P=0.001)。在年龄>50岁、乳腺密度ACR3+ACR4及病灶长径≤2cm的病例中,US结合DBT的诊断准确度高于US,差异有显著性( P<0.05)。结论 US联合DBT在一定程度上提高了诊断乳腺癌的准确度。
