常规超声阴性乳腺癌的腋窝淋巴结超声影像分析

目的总结并分析常规超声在阴性乳腺癌腋窝淋巴结评估中的作用。方法对在我院常规超声阴性的73例乳腺癌患者的术前腋窝磁共振、钼靶、超声检查结果进行分析,并与病理结果进行对照。结果73例病例中,导管原位癌20例,浸润性导管癌43例,浸润性小叶癌2例,其他8例。腋窝淋巴结有转移病例15例,无转移58例。磁共振诊断腋窝转移性淋巴结灵敏度60.0%、特异度63.8%、准确率63.0%。钼靶分别为46.7%、94.8%、84.9%。常规超声分别为60.0%、98.3%、90.4%。结论常规超声阴性乳腺癌中,腋窝淋巴结具有一定的转移比例,在灵敏度上常规超声与磁共振相当,优于钼靶;在特异度和准确率上常规超声均优于磁共振和钼靶。

The Value of the Conventional Ultrasound for the Assessment of Axillaries of Ultrasonographic Negative Breast Cancer

Objective To summarize and analyze the role of conventional ultrasound in axillary lymph node assessment of ultrasonographic negative breast cancer.Methods A retrospective study was performed on 73cases of ultrasonographic negative breast cancer between.According to the pathology results,the sensitivities,specificities and accuracies were compared among the three diagnostic methods.Results Of the 73cases,20were ductal carcinoma in situ,43were invasive ductal carcinoma,2were invasive lobular carcinoma,and 8were others.There were 15cases with axillary lymph node metastasis and 58cases without.The sensitivity,specificity and accuracy of MRI in diagnosing axillary metastatic lymph nodes were 60.0%,63.8%and 63.0%respectively.The MG are 46.7%,94.8%and 84.9%respectively.Conventional ultrasound was 60.0%,98.3%and 90.4%respectively.Conclusions Conventional ultrasound has a certain value for the assessment of axillary lymph node of ultrasonographic negative breast cancer.The sensitivity of conventional ultrasound is equivalent to MRI and superior to MG,the specificity and accuracy of conventional ultrasound is is superior MRI and MG.
