BACKGROUND: This study investigated the association of mucins and cluster of differentiation (CD) 56 with vascular and perineural invasion and survival in patients with periampullary cancer.
METHODS: Immunohistochemical staining was performed on formalin-fixed pancreatic tissue microarrays (cancer, chronic pancreatitis and normal pancreatic tissue) constructed from 126 pancreatic resections (cancer, 104; chronic pancreatitis, 22). Mucin (MUC) 1, MUC4 and MUC5AC expression was quantified using the immunohistochemical score (range 0-300), MUC3 expression was described as membranous or cytoplasmic, and expression of CD56, MUC2 and MUC6 as present or absent.
RESULTS: In cancers, vascular invasion correlated with overexpression (immunohistochemical score of 100 or more) of MUC1 (P = 0.003) and presence of MUC6 (P = 0.024), and perineural invasion correlated with overexpression of MUC5AC (P = 0.015). Reduced survival was observed with overexpression of MUC4 (P = 0.032) and MUC5AC (P = 0.048), membranous expression of MUC3 (P = 0.048), and presence of CD56 (P = 0.041). Perineural invasion also correlated with CD56 expression (P = 0.001). Overexpression of MUC4 and MUC5AC correlated with tumour recurrence (P = 0.001 and P = 0.034 respectively). Multivariable analysis identified membranous expression of MUC3 (P = 0.023), lymphatic invasion (P = 0.015) and perineural invasion (P = 0.004) as independent predictors of poor survival.
CONCLUSION: Mucins and CD56 may be markers of prognosis in patients with periampullary cancer.
