CEACAM5 and neoplasm: Supplementary Table 2 shows the results of Cox univariate analysis for DFS in 137 EBVaGC patients, indicating that tumor location, tumor size, lymphovascular invasion, and pTNM stage were potentially associated with DFS. In Table 4, further Cox multivariate analysis revealed that elevated CEA levels and pTNM stage III were independent risk factors for OS and DFS in EBVaGC patients.
