Univariate analysis results showed that high RBP‐Jκ expression (p < 0.001), high CD163 expression (p < 0.001) along with poor tumour differentiation (p < 0.001), invasion beyond the propria muscularis (p = 0.032), lymph node metastasis (p < 0.001), distance metastasis (p < 0.001) and advanced TNM stage (p < 0.001) were associated with shorter OS (Table 2). Here, CD163 is linked to neoplasm.
