In addition, we analyzed the correlation between basic characteristics and survival in GC patients and found that GC patients with T1/T2 invasion depth and no lymph node metastasis had a better prognosis, but both the univariate analysis and the multivariate analysis showed that TNFAIP2 protein expression was not significantly correlated with GC prognosis, suggesting that serum TNFAIP2 protein expression was not associated with GC prognosis. This evidence concerns the gene TNFAIP2 and metastatic malignant neoplasm in the lymph nodes.
