The results indicated a significant correlation between IL-2 (P ═ 0.025), IL-4 (P ═ 0.005), IL-8 (P ═ 0.009), IL-10 (P ═ 0.017), IL-12p70 (P ═ 0.002), IL-17 (P < 0.001), TNF-α (P < 0.001), and IFN-γ (P ═ 0.026) and lymph node metastasis (Figure 1C). Here, IL2 is linked to metastatic malignant neoplasm in the lymph nodes.
