常规超声和CEUS评价乳腺癌病灶大小

目的探讨常规超声及CEUS评估乳腺癌病灶大小的准确性及其与病理结果的相关性。方法对39例乳腺癌患者于手术切除前行常规超声及CEUS检查,分别测量病灶最大径,并与病理结果对照。按病灶大小分为≤20mm和20mm两组,分别比较两组乳腺癌常规超声与病理测量结果的差异。结果 CEUS和病理测量的病灶最大径均大于常规超声(t=8.640、8.142,P均0.01),而CEUS与病理测量结果差异无统计学意义(t=2.381,P=0.022)。CEUS测值与病理所见最大径呈线性相关(r=0.990,P0.01)。常规超声与病理测量的最大径的差异与乳腺癌病灶大小无关。结论CEUS显示乳腺癌病灶范围较常规二维超声明显增大;CEUS能较准确地评估病灶大小,且与病理结果存在良好相关性。

Conventional ultrasound and contrast enhanced ultrasoundin measuring size of breast cancer

Objective To assess the accuracy and the correlation of conventional ultrasound and CEUS with pathology in measuring size of breast cancer. Methods Conventional ultrasound and CEUS were performed in 39 breast cancer patients before surgical operation. The maximum diameter of the tumor was measured with conventional ultrasound and CEUS, and was compared with pathology. The lesions were divided into ≤20 mm and 〉20 mm group according to the diameter, and the discrepancy of the maximum diameter in the two groups were compared between conventional ultrasound and pathology. Results The maximum diameters of all lesions displayed with CEUS and pathology were larger than conventional ultra- sound （t=8. 640, 8. 142, both P〈0. 01）, but no statistical difference was found between CEUS and pathology （t=2. 381, P=0. 022）. There was linear correlation between CEUS and pathology in maximum diameter （r=0. 990, P〈0.01）. The difference of diameter obtained with conventional ultrasound and pathology was not correlated with lesions＇ size. Conclusion Breast cancers displayed with CEUS are larger than that with conventional ultrasound. CEUS can assess the tumor size accurately, which has good correlation with pathology.
