(A) Heat map of TWIST1, CD24, CD44, and ALDH1-mRNA quantification in the EpCAM+ CTC fraction from early stage breast cancer patients (n = 100). Red color represents overexpression, while green color indicates underexpression or lack of expression. Concerning the relapse or death, red color represents the relapse or death, while green color indicates no relapse or alive status. (B) Univariate Cox-regression hazard models for TWIST1 overexpression, CD44high/CD24−/low, and ALDH1high/CD24−/low and the co-expression of the mesenchymal profile, TWIST1, and the stem cell profile, CD44high/CD24−/low, and ALDH1high/CD24−/low.
