We found that CXCL11 was positively correlated with CCL4, CCL5, CXCL9, and CXCL10 in COAD, which are associated with DC, NK, and T cell recruitment and play important roles in inhibiting tumor growth and improving prognosis (Böttcher et al., 2018; Cabrero-de, Las Heras and Martínez-Balibrea, 2018). This evidence concerns the gene CCL5 and colon adenocarcinoma.
