摘　　要：目的探讨超声下乳腺癌腋下淋巴结转移的图像特征。方法回顾性分析101例乳腺癌患者临床资料,总结腋下淋巴结转移的超声图像特征。结果单因素分析发现腋下淋巴结转移病理阳性和病理阴性的患者在钙化灶、肿瘤数量、最大径及血流丰富程度等方面差异有统计学意义（P〈0.05）。Logistic回归分析发现肿瘤数量多发或弥散、有钙化灶、血流丰富程度Ⅱ-Ⅲ级以及最大径〉2 cm是腋下淋巴结转移病理阳性的独立危险因素（P〈0.05）。结论对肿瘤数量多发或弥散、有钙化灶、血流丰富程度Ⅱ-Ⅲ级以及最大径〉2 cm乳腺癌患者行超声检查时应综合考虑以提高腋下淋巴结转移的正确率。Objective To analyze the ultrasonographic features of axillary lymph node metastasis in breast cancer. Methods A retrospective analysis was conducted on 101 cases of patients with breast cancer,and the ultrasonographic features of axillary lymph node metastasis in breast cancer were summarized.Results Single factor analysis showed that calcification,tumor number,maximum diameter and richness of blood flow between axillary lymph node metastasis positive or negative patients had significant difference（P〈0.05）.Multiple-factor Logistic regression analysis showed that the number of tumors of multiple or dif-fuse,calcification,rich blood levelⅡtoⅢlevel and the maximum diameter of more than 2 cm were the independent risk factors that lead to axillary lymph node metastasis positive （P〈0.05）.Conclusion The number of tumors of multiple or diffuse,calci-fication,rich blood levelⅡtoⅢlevel and the maximum diameter of more than 2 cm are the high risk factors lead to axillary lymph node metastasis,which should be considered so as to improve the accuracy of the ultrasonic inspection.
