The Kaplan–Meier curves revealed that among CC and CXC chemokines, high mRNA expression of CCL4/5/14/19/21/22 and CXCL9/12/13/14 was notably associated with better OS (P < 0.05), while elevated expression of CCL24 and CXCL8 were associated with shorter OS in BC patients (P < 0.05). This evidence concerns the gene CXCL9 and breast cancer.
