Similar to the protein results, high MX1 mRNA expression was significantly correlated with hormonal status negativity and a high tumour grade (both p < 0.0001), positive axillary lymph node (p = 0.018), basal-like phenotype (p < 0.0001), premenopausal status, younger age (both p = 0.001) and LVI positivity (p = 0.022, Table 6). This evidence concerns the gene MX1 and neoplasm.
