乳腺早期导管癌高频彩色超声特征的诊断价值

Diagnostic value of high-frequency color Doppler ultrasound on early breast duct carcinoma

目的评价高频彩色超声诊断乳腺早期导管癌的价值。方法高频彩色超声观察30例病理诊断为乳腺早期导管癌(实验组)和50例病理诊断为乳腺小叶增生结节(对照组)的病灶,比较2组病灶超声特征的差异。结果2组患者乳腺病灶超声特征中,除纵横比≥1外,实验组出现周边高回声晕、形态不规则、边缘不清、内见微钙化灶(<0.04 cm)、有穿支血流等特征较对照组多见,2组比较差异有统计学意义(P<0.05)。乳腺早期导管癌超声特征中诊断特异性最高的是周边高回声晕(94%),敏感性最高的是边缘不清(83%)。结论高频彩色超声可以观察乳腺病灶形态学特征,是诊断乳腺早期导管癌的一种重要方法。

Objective To evaluate the diagnostic value of high frequency color Doppler ultrasound on early breast duct carcinoma.Methods Thirty cases of early breast duct carcinoma（experiment group） and fifty cases of nodular hyperplasia of lobuli mammae（control group） were observed by high frequency color Doppler ultrasound.The differences of ultrasonic feature were compared.Results There was no significant difference in the number of patients with length and width ratio≥1 between two groups（P〉0.05）.The number of patients with surrounding hyperechoic halo,irregular shape,obscure boundary,microcalcifications focus（〈0.04 cm） and perforating branch blood flow in experiment group was more than that in control group（P〈0.05）.Among the ultrasonic features of early breast duct carcinoma,surrounding hyperechoic halo had the highest specificity（94%）,and obscure boundary had the highest sensitivity（83%）.Conclusion High frequency color Doppler ultrasound can be used to observe morphological features of breast lesions,and it is an important method for the diagnosis of early breast duct carcinoma.
