One ELR+ CXC chemokine, one ELR− CXC chemokine, and the corresponding receptors among those with the highest area under the curve (AUC) values by univariate analysis (CXCL5/CXCR1 and CXCL10/CXCR3; Model 2) were also included to determine if CXC chemokine expression affects the prediction of lymph node metastasis. This evidence concerns the gene CXCL5 and metastatic malignant neoplasm in the lymph nodes.
