Predicting Pathologic Complete Response Using Breast MRI After Completion of Neoadjuvant Chemotherapy in Breast Cancer Patients WithResidual Calcifications on Mammography.Kim SH, et al.This study evaluated predictors of pathologic complete response (pCR) and surgical strategies for breast cancer patients with residual suspicious calcifications after neoadjuvant chemotherapy.Among 243 patients, the overall pCR rate was 33.7%, highest in HR-/HER2+ (59.1%) and lowest in HR+/HER2-(3.8%).MRI partial response predicted lower pCR,
