Figure 3. Post-NAC expression of BCRP predicts disease-free survival.

Kaplan–Meier survival analyses for disease-free survival in patient groups with tumours with high or low post-NAC expression levels of Pgp (A), MRP1 (B) or BCRP (C). Cut-off used to dichotomise expression into low and high groups (Pgp: 90; MRP1∶21; BCRP: 47) were determined by ROC curve analyses (Fig. S1).
