TUG1 and metastatic malignant neoplasm in the lymph nodes: The results indicated that patients with evaluated TUG1 expression progress to lymph node metastasis and distant metastasis by comparing the incidence of lymph node metastasis (HR = 2.96, 95% CI: 2.23-3.92, p < 0.001) and distant metastasis (HR = 3.56, 95% CI: 1.97-6.41, p < 0.001) between the high and low TUG1 expression groups.
