RELB and metastatic malignant neoplasm in the lymph nodes: As shown in Table 1, the clinico-pathological association study demonstrated that the expression of RelB was positively correlated with depth of tumor invasion (p = 0.018), lymph node metastasis (p < 0.001), metastasis stage (p = 0.031), and pTNM stage (p = 0.001).
