高频彩色多普勒超声诊断乳腺微小癌的应用价值

Diagnostic value of breast tiny carcinoma by high frequency color doppler ultrasonography

目的探讨高频彩色多普勒超声在诊断乳腺微小癌中的应用价值。方法选取经术后病理证实为乳腺癌且超声检查乳腺结节≤1 cm的42例患者(微小癌组),分析其声像图特征;并选择同期40例乳腺结节≤1 cm的良性病变患者(术后病理证实)作为对照组,比较两组微钙化、血流显示、阻力指数(resistance index,RI)。结果两组微钙化、血流显示、RI比较,差异均有统计学意义(P<0.05)。超声诊断乳腺微小癌的敏感度、特异度、Youden指数、诊断符合率分别为78.57%、92.50%、71.07%、85.37%。结论高频彩色多普勒超声检查对乳腺微小癌的诊断、治疗具有重要临床应用价值。

Objective To study the value of the high frequency color Doppler ultrasound in the diagnosis of breast tiny cancer. Method 42 patients with breast lesions ≤1 cm which were confirmed breast cancer pathologically （the tiny cancer group） were recruited. The sonographic features were analyzed. 40 patients with breast lesions ≤1 cm which were confirmed benign lesions pathologically at the same period were recruited as the control group. Microcalcifications, blood flow and resistance index （RI） in the two groups were compared. Results There were statistically significant differences in microcalcifications, blood flow and resistance index （RI） between the two groups （P〈0.05）. The sensitivity, specificity, Youden index and the diagnostic conformity rates of the ultrasonic diagnosis of breast tiny cancer were 78.57%（33/42）,92.50%（37/40）,71.07%,and 85.37%（70/82）, respectively. Conclusions The high frequency color Doppler ultrasound is simple and non-invasive. It has important clinical value for timely diagnosis and timely treatment of breast tiny cancer.
