MUC5AC and neoplasm: In multivariate regression analysis, older age (≥ 76 vs. ≤ 62, OR 1.37, p = 0.04) (where older age was found to be associated with poorer prognosis than younger age), tumor size (≤29mm vs ≥76mm/unknown OR 1.44 p=0.04) (where larger smaller tumor size was found to be associated with better prognosis than the larger tumor size)were determined as independent characteristics associated with OS of mucin group and year of diagnosis (2008–2013 OR 1.36, p=0.05) was determined as independent characteristic associated with CSS of mucin group.
