The univariate Cox analysis revealed that age (HR = 1.027, p = 0.033), differentiation (HR = 0.378, p = 0.019), TNM stage (HR = 2.377, p = 0.006), lymph node metastasis (HR = 3.122, p < 0.001), and PDLIM3 expression (HR = 0.419, p = 0.005) may be prognostic factors (Table 2). The gene discussed is PDLIM3; the disease is metastatic malignant neoplasm in the lymph nodes.
