乳腺叶状肿瘤的超声图像特征分析

Ultrasonography imaging characteristics analysis of the phyllodes tumor of the breast

目的通过分析乳腺叶状肿瘤超声图像特征,探讨超声在乳腺叶状肿瘤诊断中的应用价值。方法回顾性分析2015年6月~2017年6月来西安交通大学第一附属医院就诊的乳腺叶状肿瘤患者,纳入36例且均有完整的超声及病理资料。结果 36例叶状肿瘤中良性19例,交界性11例,恶性6例。超声图像特征:多呈分叶状、边界较清晰、内部回声欠均匀,钙化少见,血流较丰富,其中良性组边界清晰更为常见(χ~2=6.597,P=0.037);恶性组内部回声不均匀,可见高回声分隔及囊性无回声区(χ~2=6.840、7.049,P=0.033、0.029)。结论乳腺叶状肿瘤的超声图像具有一定特征,肿块边界是否清晰和肿块内部是否存在高回声分隔及小囊性无回声区是鉴别良恶性叶状肿瘤的重要依据。

Objective To analyze the sonographic features of phyllodes tumors of the breast（PTB） and explore the diagnostic value of ultrasonography in the PTB.Methods A retrospective analysis was performed on the patients with PTBs in the First Affiliated Hospital of Xi ＇an Jiaotong University from June 2015 to June 2017,including 36 masses with complete ultrasound and pathological data.Results Among the 36 PTBs,19 PTBs were benign,11 PTBs were borderline and 6 were malignant tumors according to the pathologic diagnosis.The ultrasonic image feature of the masses were commonly observed to have more a clear-cut boundary,and inhomogeneous internal echo,the rarely calcification and more blood flows.The clear boundary was more commonly detected in the benign phyllodes tumors（χ~2=6.597,P =0.037）.The inhomogeneous internal echo was more commonly observed in the malignant,with high echo separation and a cystic echo-free area was more commonly observed in these malignant tumor（χ~2=6.840,P = 0.033;χ~2=7.049,P =0.029）.Conclusion The ultrasonic imaging of PTB exhibits definite characteristics,and the border with high echo separation and cystic areas in the tumors can be used to differentiate between benign and malignant PTBs.
