Univariate Cox regression analysis showed that age (P = 0.007), TNM stage (P < 0.001), lymph node metastasis (P = 0.0011) and GXYLT2 expression (P = 0.048) were significant factors affecting the survival time of patients with GC (Figure 3(b)). Here, GXYLT2 is linked to metastatic malignant neoplasm in the lymph nodes.
