Abstract:
Objective To compare the sonographic and pathologic features of calcified and non-calcified ductal carcinoma in situ DCIS Methods A total of 83 lesions in 82 consecutive patients with pathologically confirmed pure DCIS were recruited One patient had bilateral lesions All lesions were divided into calcified DCIS and non-calcified DCIS according to the presence of calcifications on mammography Their sonographic features and pathologic reports for all patients with DCIS were retrospectively reviewed Statistical comparisons were performed using the chi-square test Results 1 Calcified DCIS showed positive ultrasound US findings in 80% 44 55 of cases The most common US finding was nonmass lesions 43 6% 24 55 Nine cases had pure ductal dilatations 16 4% 9 55 Non-calcified DCIS showed positive US findings in 96 4% 27 28 of cases The most common US finding was mass 89 2% 25 28 Two cases had pure ductal dilatations 7 1 % 2 28 No significant difference was found in the shape margin orientation posterior feature of a mass between the calcified and non-calcified groups P >0 05 Significant difference was observed in the size boundary echogenicity on ultrasound of the two groups P <0 05 2 At histopathology the pathological scores high nuclear grade positive ER status positive PR status positive Ki67 status and the presence of Her-2 neu oncogene were more common in the calcified group than in the non-calcified group Conclusions Calcified and non-calcified pure DCIS have different pathologic and sonographic features Calcified DCIS has more aggressive histological features than non-calcified DCIS.
