摘要
目的探讨超声检查对乳腺癌腋窝淋巴结(ALN)转移的诊断价值。方法对经手术病理证实的98例乳腺癌且超声显示有ALN的患者,应用灰阶超声(US)和能量多普勒超声(PDI)进行淋巴结长短比(L/S)、结构及血流分布状态的分析。结果71.7%的转移性淋巴结L/S≤2,23.1%的非转移性淋巴结L/S≤2;转移性淋巴结呈皮质偏心增厚型占60.9%,非转移性淋巴结呈皮质狭窄型占76.9%;转移性淋巴结血流分布呈周边型者65.2%,非转移性淋巴结血流分布呈淋巴门型者76.9%。以L/S≤2、偏心增厚型皮质、周边型血流为综合判断乳腺癌ALN转移的标准,敏感度为91.3%,特异度为88.5%。结论超声检查对乳腺癌ALN转移具有较高的诊断价值。
Objective To evaluate the value of ultrasonography in diagnosis of axillary lymph node（ALN） metastasis in breast cancer. Methods The long-short axis ratio（ L/S）, structure, blood flow pattern of ALN in 98 patients with breast cancer diagnosed by pathology were analyzed by gray-scale ultrasonography（US） and power Doppler imaging（PDI）. Results L/S≤2 was found in 71.7% of metastatic ALN and in 23.1% of non-metastatic ALN. The eccentric thickening of the cortical zone was found in 60.9% of metastatic ALN. The thinning of cortices was found in 76.9% of non-metastatic ALN. The 65.2% of metastatic ALN had peripheral flow, while 76.9% of non-metastatic ALN had hilar flow. The sensitivity and specificity of uhrasonography were 91.3% and 88.5% ,respectively, based on the criteria of L/S≤2, eccentric cortical thickening and peripheral flow. Conclusion Ultrasonography is a valuable method for diagnosing ALN metastasis in breast cancer.
