目的探讨三阴性乳腺癌的超声造影特征。方法回顾分析病理证实乳腺癌患者300例,三阴性45例,非三阴性255例(随机选取51例为对照组)。结果三阴性乳腺癌37.8%圆形或椭圆形,35.6%边缘光整,75.6%后方回声无改变,71.1%无钙化灶,80.0%血流丰富;造影上66.7%边界清晰,73.3%高灌注,肿块整体以及灌注最强区的Peak较大,灌注最强区的Sharpness小,上述指标与非三阴性组间有统计学差异(P<0.05)。结论三阴性乳腺癌超声造影上有一定特征。
Objective To investigate the contrast-enhanced ultrasound features of triple negative breast cancer. Methods Retrospective analysis of pathological confirmed 300 cases of breast cancer patients, 45 cases of triple negative, non-triple negative 255 cases (51 cases were randomly selected as the control group). Results 37.8% of the patients with triple-negative breast cancer were round or oval with 35.6% marginal edification, 75.6% of the posterior echoes unchanged, 71.1% without calcification and 80.0% The whole mass and the peak of the strongest perfusion area were larger and the Sharpness of strongest perfusion area was smaller. There was a significant difference (P <0.05) between the above indexes and the non-triple negative group. Conclusion Triple negative breast cancer has some characteristics on contrast-enhanced ultrasound.
