BACKGROUND Leukocytes,such as T cells and macrophages,play an important role in *** chemokine ligand(CCL)4,which is produced by lymphocytes and macrophages,has been found to be expressed in the mucosa of the gastrointestinal tract and is a potent chemoattractant for various *** To examine CCL4 expression and its genetic polymorphism rs10491121 in patients with colorectal cancer(CRC)and evaluate their prognostic *** Luminex technology was used to determine CCL4 Levels in CRC tissue(n=98),compared with paired normal tissue,and in plasma from patients with CRC(n=103),compared with healthy controls(n=97).Included patients had undergone surgical resection for primary colorectal adenocarcinomas between 1996 and 2019 at the Department of Surgery,Ryhov County Hospital,Jönköping,*** transcription quantitative PCR was used to investigate the CCL4 gene expression in CRC tissue(n=101).Paired normal tissue and TaqMan single nucleotide polymorphism assays were used for the CCL4 rs10491121 polymorphism in 610 CRC patients and 409 healthy *** The CCL4 protein and messenger RNA expression levels were higher in CRC tissue than in normal paired tissue(90%,P<0.001 and 45%,P<0.05,respectively).CRC tissue from patients with localized disease had 2.8-fold higher protein expression levels than that from patients with disseminated *** CCL4 protein expression levels in CRC tissue were associated with a 30%lower cancer-specific survival rate in patients(P<0.01).The level of plasma CCL4 was 11%higher in CRC patients than in healthy controls(P<0.05)and was positively correlated(r=0.56,P<0.01)with the CCL4 protein level in CRC *** analysis of CCL4 gene polymorphism rs10491121 showed a difference(P<0.05)between localized disease and disseminated disease in the right colon,with a dominance of allele A in localized ***,the rate of the A allele was higher among CRC patients with mucinous cancer than among th
