IL4R and neoplasm: When we performed multivariate analysis with sex, age, tumor stage, histologic nuclear grade, tumor necrosis, and the expression of IL4Rα and IL13Rα1, tumor stage (CSS; p < 0.001, RFS; p < 0.001) and IL4Rα expression (CSS; p = 0.001, RFS; p = 0.004) were the independent prognostic indicators for both CSS and RFS (Table 3, model 1).
