EIF1AX and metastatic malignant neoplasm in the lymph nodes: Based on the univariate Cox analysis, predictors of shorter DFS were lymph node metastasis (95% confidence interval (CI) 1.929–39.145, p = 0.005) advanced disease (95% CI 1.646–152.169; p = 0.017), widely invasive histologic subtype (95% CI 1.084–21.761, p = 0.039), EIF1AX mutations (95% CI 1.887–52.892; p = 0.007), and TERTp mutations (95% CI 1.254–25.298; p = 0.024).
