FABP1 and metastatic malignant neoplasm in the lymph nodes: In the analysis of the risk factors in DFS, the univariate analyses showed that lymph node metastasis (HR = 2.09, 95%CI: 1.03-4.25, P = 0.042), hepatic metastatic nodules (HR = 2.62, 95%CI: 1.09-6.30, P = 0.032) and FABP1 expression in DI region (HR = 2.21, 95%CI: 1.17-4.18, P = 0.015) were all associated with DFS in GBC patients (Supplementary Table S8).
