FOXA1 and neoplasm: Univariate analysis showed a significant association between RFS and tumour size (p < 0.001), nodal involvement (p < 0.001), adjuvant chemotherapy (p = 0.005), AR status (p = 0.034), AR/FOXA1 co-expression (p = 0.020), TILs density (p = 0.002) and PD-L1 expression by TILs (p = 0.018) (Supplemental table 4).
