RAC1 and breast carcinoma: When we associated Rac1 immunoreactivity with disease-free survival and breast-cancer-specific survival, we could not detect any statistically significant difference between Rac1-positive and Rac1-negative cases (p = 0.42 for disease-free survival (Figure 2C) and p = 0.18 for breast-cancer-specific survival (Figure 2D)).
