Cyto, cytoplasm; Nuc, nucleus.
IHC scores for nuclear factor-κB (NF-κB) (p65 active antibody) and interleukin-8 (IL-8) across histological series.
Staining scored: weak, moderate (Mod) and strong relative to negative (no antibody) and positive (breast for NF-κB and tonsil for IL-8) controls.
*p<0.05 relative to squamous tissue.
†Adenocarcinoma staining is significant relative to both Barrett’s tissue and squamous tissue.
