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 of color Doppler ultrasonographic features in young and middle-aged patients with breast cancer. Methods: The color Doppler ultrasound images of 253 cases of breast cancer confirmed by surgery and pathology were retrospectively analyzed. According to the pathological changes, they were divided into direct signs and indirect signs, and the clinical features of young patients (≤35 years old) 35 years old) breast ultrasound differences in the characteristics of the image. Results: In the young group and the middle-aged group, there were significant differences in tumor appearance, edge burr, internal echo, microcalcification, posterior echo, aspect ratio, peak systolic blood flow velocity There was no significant difference in the change of continuous fascia line, continuous fascia line and Cooper ligament change (P> 0.05), while in the direct signs of blood flow classification, perforating branches, resistance index (RI) and indirect signs In axillary lymph nodes were statistically significant differences (P <0.05). Conclusion: There are differences in color Doppler flow imaging, grading of blood vessels, resistance index and axillary lymph node enlargement between young breast cancer and middle-aged and elderly breast cancer in color Doppler ultrasound imaging. Emphasis on these characteristics in practical application can improve young Sensitivity and accuracy of ultrasonic diagnosis of breast cancer.
