Concordance of Mammography and Sonography with Pathology Reports in the Size of Breast Tumors

Background and Breast cancer is the most common type of cancer in women and the second cause of cancer death in Iran. Widespread use of mammography and sonography could increase survival in patients with early detection. Sensitivity and specificity of mammography and sonography are different in various sources. This study aimed at assessing the concordance of mammography-sonography reports with pathology reports in tumor size among patients with breast cancer. This research studied 100 women with pathologically proven invasive breast cancer attending Ramsar Imam Sadjad Hospital, 2016-2017. The concordance of mammography-sonography reports with pathology report was studied. Pearson correlation coefficient was applied to investigate the correlations. The mean age of the patients was 48±7.45. Most of them were married with history of labor and breastfeeding. Many patients had BMI>25. In most cases left breast and external upper quadrant were involved and most tumors had ductal pathology. The correlation coefficient between tumor size in mammography and pathology was 0.80 (p<0.0001) and between ultrasonography and pathology was 0.81 (p<0.0001). In most cases, tumor size in mammography and sonography was found to be similar to that reported by pathology. Compared to mammography, sonography was found to be more sensitive in measuring the tumor size which was also more concordant with pathology results.
