Tumour epithelial cell expression of NF-κB p105 (P=0.001) and vimentin (P=0.005), stromal cell expression of NF-κB p105 (P=0.007) and Par6 (P=0.0001), and the clinicopathological variables T stage (P=0.02), N stage (P=0.0001) and performance status (P=0.03) were all independent prognostic factors for survival. This evidence concerns the gene PARD6A and neoplasm.
