NELFA and metastatic malignant neoplasm in the lymph nodes: As shown in Table 2, the univariate Cox regression analysis confirmed that the NELFA mRNA‐positive rate (P = 0.010), gender (P < 0.001), lymph node metastasis (P < 0.001), T stage (P = 0.009) and TNM stage (P < 0.001) were vital prognostic factors.
