For the indexes CCL26/CCR3, CXCL5/CEA, log CXCL14/CA 19-9, CCL26/CCL2, log CCL26/CCL2, log CCR3/CCL2, CCL15/CXCL5, CCL4/CXCL16, CCL4/CXCL14, log CCL4/CXCL14, CXCL16/CXCL5, log CXCL16/CXCL5, CXCL5/CXCL14 and log CXCL5/CXCL14, we observed statistically significant differences only in the comparison between the control group and the group with advanced cancer, which proves their relationship with the presence of metastases. The gene discussed is CXCL5; the disease is cancer.
