Clinical and pathological variables such as gender (P = 0.023), age (P = 0.004), tumor size (P < 0.001), unclassified mucin phenotype (P = 0.006), advanced stage (P < 0.001), lymphatic invasion (P < 0.001), vascular invasion (P = 0.003), perineural invasion (P < 0.001), and MSI-H (P = 0.033) significantly affected OS. Here, MUC5AC is linked to neoplasm.
