Patients undergo multiparametric MRI (including T2WI, DWI and DCE-MRI) at baseline, after 2 courses of neoadjuvant chemotherapy, and prior to the surgery at least 8 weeks after the treatment procedure. Patients undergo biopsy test in one week after the baseline MRI scan to detect the biomarkers including ER, PR, Her-2 and Ki-67, which can be used to select the treatment plan referring to the NCCN clinical guidelines. After the surgery, responses to neoadjuvant chemotherapy are determined according to the histopathologically examination of the surgically resected specimens.
After completion of treatment procedure, patients are followed up for 5 years.
