MUC5AC and neoplasm: For OS, univariate analyses with the Cox proportional hazard model found that older age (p < 0.001), history of smoking (p = 0.059), polymetastases type tumor recurrence (p = 0.002), shorter surgical bronchial margin (p = 0.021), higher T stage (p = 0.001), higher N stage (N1 vs. N0, p = 0.068 and N2 vs. N0, p < 0.001, respectively), poorly differentiated tumor (p = 0.001), presence of mucin (p = 0.039), presence of STAS (p = 0.091), consolidative CT morphology (p = 0.001), and well defined heterogenous GGO on CT (p = 0.048) were associated with worse prognosis.
