According to the results of a univariate analysis, the overall survival showed significant relationships with the density of TAMs (p = 0.027), age (p = 0.036), venous involvement (p = 0.010), lymph node metastasis (p = 0.024), CEA (p = 0.021), and CA19–9 (p = 0.017). Here, CEACAM5 is linked to metastatic malignant neoplasm in the lymph nodes.
