Abstract
We evaluated the mammographic and histopathologic features of screening mammography-detected ductal carcinoma in situ (DCIS) based on the breast cancer subtypes determined by immunohistochemistry. A total of 94 patients with 94 screening mammography-detected DCIS were included in this study. Mammographically, human epidermal growth factor receptor 2 (HER2)-positive DCIS was more commonly associated with calcifications than estrogen receptor (ER)-positive and triple-negative DCIS (P=.003). Histopathologically, HER2-positive DCIS and triple-negative DCIS were associated with high nuclear grade (P≤.001) and comedo necrosis (P≤.001) than ER-positive DCIS.
