Fig. 5From: Identifying an early treatment window for predicting breast cancer response to neoadjuvant chemotherapy using immunohistopathology and hemoglobin parametersPartial response in a high-grade ER-positive/HER2-negative tumor in a 72-year-old woman with a locally recurrent invasive ductal carcinoma. She was treated with cyclophosphamide and docetaxel every 3 weeks for four cycles before surgery. Left panel: US images at four time points of pretreatment, at day 7, at the completion of cycle (Cyc) 1, and before surgery. The tumor was ill-defined with an unclear boundary seen by US. Right panel: tHb concentration maps obtained at the corresponding time points. The patient had a partial response with residual invasive carcinoma of 2.8Â cm, Miller-Payne grade 3Back to article page
