CEACAM5 and neoplasm: After screening based on the Fine–Gray competitive risk model and multivariate analysis, the results showed that the independent risk factors related to patient CSS were age ≥ 65 years (p < 0.001), black race (p = 0.032), primary tumor site in the right colon (p < 0.001), history (p = 0.021), grade poorly (p < 0.001), tumor size >5 cm (p < 0.001), N1 (p = 0.019) or N2 stage (p < 0.001), CEA elevated (p < 0.001), no surgery at the primary site (p < 0.001), and no surgery at the distant metastasis site (p < 0.001) (Table 2).
