By univariate analysis, we identified three prognostic factors: histological grade (low, middle or high), TNM stage (I/II, III/IV) and TUG1 expression, whereas the other clinical parameters, such as lymph node metastasis (N0, N1 and above), age (≤60 years and >60 years), gender (male and female), tumor size (≤3 cm and >3 cm) and history of smoking were not significant prognosis factors. The gene discussed is TUG1; the disease is metastatic malignant neoplasm in the lymph nodes.
