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

Table 4

Analysis of immunohistochemical data of various indicators in nonluminal breast cancer tissue ().

Groups	CD24	CD44	E-cadherin	N-cadherin	β-Catenin	Vimentin
Control
Precancer tissue before NAC	^△	^△	^△		^△	^△
Tumor tissue before NAC	^△	^△		^△	^△	^△
Precancer tissue after NAC	^△	^△▲	^▲
Tumor tissue after NAC		^▽		^△▽	^▽	^△▽

Note: ^△: compared with the control group, ; ^▲: compared with paracancer tissue before NAC, ; ^▽: compared tumor tissue before NAC, . Because the data do not conform to the normal distribution, a rank-sum test was used for analysis.
