乳腺癌及其淋巴结转移的超声声像特征分析

Ultrasonographic Features of Breast Cancer and Related Lymph Node Metastasis

目的回顾性总结乳腺癌及其淋巴结转移的超声声像特征。方法回顾性分析2014—2018年到本溪市中心医院体检或者就诊,并且经手术切除的女性乳腺癌患者89例的超声检查资料,对其肿块、淋巴结和血流情况进行分析。结果超声对乳腺肿块的诊断准确率为93.26%;对淋巴结转移的诊断准确率为82.69%。乳腺癌肿块形态不规则,与正常组织分界不清,呈毛刺征,纵横比多>1(59.04%);肿块内部多见强回声,回声分布不均匀,部分患者可见钙化灶(32.53%)或囊性灶(22.89%);肿块后方回声多呈衰减表现(68.67%)。肿块内部血流异常者较多,0级血流占13.25%;Ⅰ级血流占28.92%;Ⅱ级血流占37.35%;Ⅲ级血流占20.48%。结论超声对乳腺癌及其淋巴结转移诊断准确率高,成像清晰,但仍存在着一定的漏诊情况,临床上应予以注意。

Objective To retrospectively summarize the ultrasonographic features of breast cancer and related lymph node metastasis. Methods The ultrasonographic data of 89 female patients with breast cancer who underwent physical examination or surgical resection in our hospital from 2014 to 2018 were retrospectively analyzed, and tumor mass, lymph nodes and blood ow were analyzed. Results The diagnostic accuracy of ultrasound for breast masses and lymph node metastasis was 93.26% and 82.69%, respectively. The shape of breast cancer mass is irregular, and the demarcation between breast cancer and normal tissues is not clear, showing burr sign, the aspect ratio is more than 1 (59.04%). Strong echoes are found in the mass, and the echo distribution is uneven. Some patients can see calcifed lesions (32.53%) or cystic lesions (22.89%). The echo behind the mass is attenuated (68.67%). There were more abnormal blood ows in the tumors, with grade 0 blood flow accounting for 13.25%, grade blood flow accounting for 28.92%, grade blood flow accounting for 37.35%, and grade blood flow accounting for 20.48%. Conclusion Ultrasound has high diagnostic accuracy and clear imaging for breast cancer and related lymph node metastasis, but there are still some cases of missed diagnosis, which should be paid attention to clinically.
