Changes in Tumor Stem Cell Markers and Epithelial-Mesenchymal Transition Markers in Nonluminal Breast Cancer after Neoadjuvant Chemotherapy and Their Correlation with Contrast-Enhanced Ultrasound

Figure 2

Contrast-enhanced ultrasound before and after NAC in nonluminal breast cancer patients. (a) Contrast-enhanced ultrasound image before NAC showing high enhancement. (b) Time-intensity curve before NAC showing fast-in and high-enhancement relative to adjacent cancer tissue. (c) Contrast-enhanced ultrasound image after NAC. The lesions shrank, showing slightly lower enhancement without enlargement. (d) Time-intensity curve after NAC, showing equal-in and the same enhancement as the adjacent tissues.
