Univariate analysis showed that clinical stage (HR = 2.8405), lymph node metastasis (HR = 6.0870), differentiation (HR = 3.4393), SNCG expression (HR = 4.1987), Snai1 expression (HR = 3.3610), and SNCG/Snai1 (HR = 3.0648) were risk factors of OS (Figure 8(a)). The gene discussed is SNAI1; the disease is metastatic malignant neoplasm in the lymph nodes.
