Moreover, the overall and cancer-related survival was significantly increased in patients with normal CEA concentrations compared to elevated CEA concentrations (overall: CEA normal 82.3% vs. CEA elevated 40.5%; p < 0.001; cancer-related: CEA normal 90.8% vs. CEA elevated 52.1%; p < 0.001; Table 3). The gene discussed is CEACAM5; the disease is cancer.
