In the multivariate analysis, lymph node metastasis (HR = 0.553, 95%CI: 1.684–14.690, P = 0.004) were independent factors associated with OS, but the influence of CCAT2 (HR = 0.654, 95%CI: 0.737–9.575, P = 0.135) on OS was lost (Table 4). The gene discussed is CCAT2; the disease is metastatic malignant neoplasm in the lymph nodes.
