As shown in Table 2, univariate analysis displayed that a few prognosis factors (distant metastasis, depth of invasion, lymph node metastasis, venous invasion, nervous invasion, obstruction, TNM stage, tumor diameter and SNHG1 expression) were statistically significant risk factors influencing OS and PFS of patients. The gene discussed is SNHG1; the disease is metastatic malignant neoplasm in the lymph nodes.
