Table 1.

Subject and tumor characteristics. Demographic, histological, and immunohistochemical data are provided for all subjects and divided into complete responder (pCR) and noncomplete responder (non-pCR) groups. For histological information, IDC refers to invasive ductal carcinoma, ILC refers to invasive lobular carcinoma, and DCIS is ductal carcinoma in-situ. ER, PR, and Her2 represent estrogen receptor, progesterone receptor, and human epidermal growth factor receptor status, respectively.
