Similarly, the univariate analysis showed that a worse DFS was associated with high CEA (HR: 2.412; 95% CI: 1.452–4.007; P = 0.001) and CA15-3 (HR: 2.586; 95% CI: 1.738–3.847; P < 0.001) levels along with other parameters, including tumor status, N status, TNM staging, and histological grade (Table 2). The gene discussed is CEACAM5; the disease is neoplasm.
