Figure 2. Prevalence of EpCAM^-/CD49f⁺ with histopathologic characteristics. Analyzing of 150 breast cancer samples stratified to tumor size (A), node status (B), tumor grade (C; low=grade I and II, high=grade III), recurrence (D), distant metastasis (E), and estrogen receptor (ER) expression (F). Tumor containing EpCAM^-/CD49f⁺ are associated with higher tumor grade (C; p=0.031) and distant metastasis (E; p=0.048). Chi-square exact and Fisher exact test were performed.
