Abstract:
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.
