High VIL2 expression was associated with larger tumour size (χ2 = 8.474, d.f. = 1, p = 0.004), higher tumour grade (χ2 = 10.205, d.f. = 2, p = 0.006), HER2‐positive tumours (χ2 = 9.928, d.f. = 1, p = 0.002), ER‐positive tumours (χ2 = 34.598, d.f. = 1, p < 0.001) and PAM50 subtype (χ2 = 61.481, d.f. = 4, p < 0.001) (Table 3). This evidence concerns the gene EZR and neoplasm.
