Objective To investigate the characteristics of breast image and the factors associated with axillary lymph node metastasis.Methods 80 patients with breast cancer undergoing ultrasonography in our hospital from May 2012 to June 2014 were randomly selected as the object of study.Analyzed characteristics of color ultrasound image,observed the specific circumstance of primary lesions,with pathological diagnosis of patients as the standard,analyzed related factors of axillary lymph node metastasis.Results The largest diameter of primary lesions,blood flow rich degree,the number of tumors,and calcified lesions had great relationship with axillary lymph node metastasis;tumor with calcified lesions,multiple or diffuse tumor,tumor with grade Ⅱ-Ⅲ rich degree of blood flow were prone to the phenomenon of axillary lymph node metastasis,with statistically significant differences (P＜0.05).The multivariate analysis showed that relative risk of calcified lesions for axillary lymph node metastasis was relatively low,only 0.947;but relative risk of blood flow rich degree for axillary lymph node metastasis was relatively high,reaching to 8.211.Conclusion Preoperative ultrasonography for breast cancer patients can accurately understand specific circumstance of lymph node,the diameter of primary lesion,and blood flow imaging,which provides safe and reliable criteria for surgical treatment,helps to improve the treatment effect of breast cancer,has good clinical application value.%目的 探讨超声下乳腺图像的特点与腋淋巴结转移相关因素.方法 随机选取2012年5月至2014年6月在本院就诊的80名乳腺癌患者作为研究对象,对患者进行超声检查,分析患者超声彩色图像的特点,观察患者原发病灶的具体情况,并将患者的病理诊断作为标准,分析患者腋淋巴结转移的相关因素.结果 80名患者原发病灶的最大直径、血流丰富程度、肿瘤数量以及有钙化病灶与腋淋巴转移有很大的关系,钙化病灶、多发或弥漫性,血流丰富度为Ⅱ～Ⅲ级的肿瘤容易出现腋淋巴转移的现象,差异有统计学意义(P＜0.05).经过单因素分析后将有意义的因素进行多因素分析,经过分析后钙化灶对腋淋巴转移的相对危险度比较低,只有0.947,但血流丰富程度对腋淋巴转移的相对危险度比较高,达到8.211.结论 对乳腺癌患者进行术前的超声检查,能够准确的了解患者的淋巴结的具体情况和患者原发病灶的直径和血流显像,为手术治疗提供安全可靠的标准,有助于提高乳腺癌的治疗效果,具有良好的临床应用价值.
