目的:对乳腺癌新辅助化疗(NCT)前后进行二维和彩色多普勒超声检查,观察其声像图特征并加以分析,以评价其疗效。方法:对比分析47例乳腺癌NCT前后超声声像图各主要征象的变化。结果:47例患者新辅助化疗后超声检查显示,化疗后原发灶明显缩小甚至消失,原发灶内血流丰富程度降低或消失,最高流速(Vmax),和阻力指数(R1)降低,相应病例腋窝淋巴结转移灶也呈特征性改变。结论:乳腺癌NCT前后超声声像图变化可以为判断疗效提供可靠依据。
OBJECTIVE: To perform two-dimensional and color Doppler ultrasonography before and after neoadjuvant chemotherapy (NCT) for breast cancer and to observe and analyze the features of sonography to evaluate its curative effect. Methods: The changes of major signs of ultrasound sonography before and after NCT in 47 cases of breast cancer were analyzed. Results: After neoadjuvant chemotherapy in 47 patients, ultrasonography showed that the primary tumor decreased or even disappeared after chemotherapy, the degree of blood flow decreased or disappeared in the primary tumor, and the maximum velocity (Vmax) and resistance index (R1) decreased. Correspondingly, Case axillary lymph node metastases also showed a characteristic change. Conclusion: The changes of ultrasound echocardiography before and after breast cancer NCT can provide a reliable basis for judging the curative effect.
