年轻和中老年乳腺癌彩色多谱勒超声图像特征的对比分析

Contrast Analysis of the Different Characteristics of Color Doppler Ultrasound Images between the Young and the Middle or Elder Patients with Breast Cancer

目的:分析年轻和中老年乳腺癌彩色多谱勒超声图像特征的差异。方法:对手术病理证实的253例乳腺癌患者的彩色多谱勒超声图像进行回顾性分析,其按病理改变分为直接征象及间接征象,分析年轻组(≤35岁)和中老年组(>35岁)乳腺癌超声图像特征的差异。结果:年轻组和中老年组在直接征象中肿块形态、边缘毛刺、内部回声、微钙化、后方回声、纵横比、收缩期峰值血流速(Vmax)以及间接征象中肿块周边高回声晕、浅筋膜连续线改变、深筋膜连续线改变、Cooper韧带改变上均没有统计学差异(P>0.05);而在直接征象中的血流分级、穿支血管、阻力指数(RI)和间接征象中的腋窝淋巴结肿大均具有统计学差异(P<0.05)。结论:在彩色多普勒超声图像特征上,年轻乳腺癌和中老年乳腺癌在血流分级、穿支血管、阻力指数和腋窝淋巴结肿大方面有差异,在实际应用中重视这些特征能提高年轻乳腺癌超声诊断的灵敏性和准确性。

Objective： To analyze the differences with color doppler ultrasound between the young and the middle or elder patients with breast cancer. Methods： Color doppler ultrasound images of 253 cases with breast cancer confirmed by operation and pathology were studied retrospectively. Divided them into direct and indirect signs according to the pathology. Analysis of the different characteristics with color doppler ultrasound between the young group（≤ 35yearold）and the middle or elder group（〉35-year-old）with breast cancer. Results： Compared with the young group and the middle or elder group, there was no statistical significance of the direact signs of tumor shape, spiculated margin, internal echo, micro calcification, posterior echo, transverse-longitudinal axis ratio （L/T）, systolic maximum velocity （Vmax） and the indireact signs of hyperechoic halo, changes of superficial fascia, changes of deep fascia and changes of Cooper′s ligament （P〉0.05）;There was statistical significance of the direact signs of blood flow signals scores, perforating blood vessels, resistance index （RI） and the indireact signs of enlarged axillary lymph nodes（P〈0.05）. Conclusion： Attention the different dharacteristics of color doppler ultrasound images between the Young and the Middle or Elder Patients with breast cancer, could further improve the sensitivity and accuracy of young patients with breast cancer.
