Abstract

The purpose of our study was to retrospectively compare the sonographic and pathologic features of screening-detected and symptomatic ductal carcinoma in situ (DCIS). Of 5,790 cases diagnosed as breast cancer at our institution between January 1998 and December 2005, 528 (9.1%) cases were DCIS. We found 106 screening-detected and 125 symptomatic DCIS lesions in 226 patients (age range, 20-77 years; mean age, 47.8 years) who underwent preoperative whole-breast sonography and mammography. Three radiologists reviewed the sonographic features of these 231 cases of DCIS by consensus according to Breast Imaging Reporting and Data System (BI-RADS). The pathologic features were also reviewed. Statistical comparisons were performed using the chi-square test, the Fisher's exact test, and the Mann-Whitney U test. On sonography, masses (p < 0.001) and associated ductal change (p = 0.019) were more common in symptomatic than in asymptomatic patients. Associated microcalcifications and posterior shadowing were more frequently found in screening-detected than in symptomatic DCIS (p < 0.001). On mammography, microcalcifications were more common in screening-detected than in symptomatic DCIS, and masses were more common in symptomatic than in s...Continue Reading
