According to the results of a univariate analysis, the progression-free survival showed significant relationships with the density of TAMs (p = 0.002), lymphatic involvement (p = 0.011), lymph node metastasis (p = 0.001), CEA (p = 0.014), and CA19–9 (p < 0.001). This evidence concerns the gene CEACAM5 and metastatic malignant neoplasm in the lymph nodes.
