IL13RA1 and metastasis: This subgrouping for the co-expression patterns of IL4Rα and IL13Rα1 was significantly associated with age (p = 0.007), tumor size (p = 0.029), tumor stage (p = 0.027), and lymph node metastasis (p = 0.017) (Table 1), and significantly associated with CSS (Log-rank, p < 0.001)and RFS (Log-rank, p < 0.001) (Figure 1E).
