Figure 7. VWF mRNA expression according to the Prosigna Breast Cancer Prognostic Gene Signature Assay (PAM50) subtype in 840 samples, all histologies. Tukey’s honest significant difference post hoc test showed that VWF mRNA expression of the normal subtype was significantly greater than that of the other subtypes (p<0.001). LumA: Luminal A; LumB: luminal B; HER2: human epidermal growth factor receptor 2.
