摘　　要：目的：比较乳腺 X 线和超声检查对于乳腺导管原位癌病变范围的术前诊断价值。方法回顾性分析经手术病理证实的乳腺导管原位癌患者87例,所有患者具有完整的乳腺 X 线和超声检查资料,分别将2种方法所测量的病变最大径与病理所测量的病变最大径进行比较,将 X 线和超声检查测量病变最大径界于病理测量病变最大径±0.5 cm 之间的病例定义为与病理结果一致。用 Pearson 相关分析比较2种方法所测量的病变最大径与病理测量的病变最大径的相关性。结果87例乳腺导管原位癌病理测量的病变最大径范围为0.4～7.0 cm,平均（2.4±1.3）cm。X 线测量的病变最大径范围为0.8～6.9 cm,平均（2.6±1.2）cm。超声测量的病变最大径范围为0.5～4.8 cm,平均（2.3±1.0）cm。X 线与病理测量病变最大径的相关系数为0.724,P 〈0.001。超声检查与病理测量病变最大径的相关系数为0.532,P 〈0.001。结论对于乳腺导管原位癌术前病变范围的评估,乳腺 X 线的诊断价值高于超声检查。Objective To compare the accuracy of mammography and ultrasonography in evaluating the tumor size of breast ductal carcinoma in situ before operation.Methods Eighty-seven patients with breast ductal carcinoma in situ confirmed by surgery pathology were retrospectively analyzed.All of the mammography and ultrasonography data were well-documented.The maximum diameter of the tumor was measured by mammography,ultrasonography and pathology,respectively.It was considered concordant if the difference between the imaging size and pathologic size was less than 0.5 cm.Pearson correlation analysis was used to determine the relation of imaging size with pathologic size.Results The range of the maximum diameter of the tumors measured by pathology,mammography and ultrasonography was 0.4-7.0 cm,0.8-6.9 cm and 0.5-4.8 cm,respectively.The mean value was （2.4±1.3）cm,（2.6±1.2）cm and （2.3±1.0）cm,respectively.The coefficient correlation between mammographic and pathologic size was 0.724,and between ultra-sonographic and pathologic size was 0.532.Conclusion Mammography is more accurate than ultrasonography in size assessment of breast ductal carcinoma in situ.
