TUG1 and metastatic malignant neoplasm in the lymph nodes: Through comparing the incidence of lymph node metastasis and tumor progression between high and low lncRNA TUG1 expression group by random model, we found that patients with increased lncRNA TUG1 levels failed to show incline to lymph node metastasis (HR: 1.16, 95% CI: 0.82–1.62, P = 0.40) and tumor progression (III/IV vs. I/II: HR 1.16, 95% CI: 0.74–1.81, P = 0.52).
