Stratifying the cases based on histology revealed that the significance of better survival for high tumour epithelial NF-κB p105 and vimentin expression was limited to ACs (P=0.03 and P=0.0004, respectively) and stromal NF-κB p105 and Par6 expression to SCCs (P=0.001 and P=0.0009, respectively). Here, PARD6A is linked to neoplasm.
