In the current study, we aimed to investigate the possible role of MCP-1 -2518 A>G and CC chemokine receptor 2 (CCR2) V64I polymorphisms in patients with lung cancer. Sixty-five patients with lung cancer (57 with NSCLC and 8 with SCLC) and 57 healthy controls were enrolled. Polymerase chain reactionrestriction fragment length polymorphism (PCR-RFLP) method was used. Genotype distribution of monocyte chemoattractant protein 1 (MCP-1) -2518 A>G polymorphism in lung cancer patients was as follows: 30 for AA, 30 for AG and 5 for GG genotype. Frequency of minor G allele in patients and controls were found as 30.8% and 23.7%, respectively. In patients, genotype distribution of CCR2 V64I polymorphism was as follows: 47 for GG, 16 for GA, and 2 for AA. Frequency of minor A allele was found in patients and controls as 15.4% and 19.2%, respectively. Genotype distribution and allele frequencies of MCP-1 and CCR2 polymorphism were not statistically different between patients and controls (p values >0.05 for both polymorphisms). In lung cancer patients, there was no significant association between smoking status and MCP-1 and CCR2 polymorphisms. Similarly, no significant association was found between distant organ metastasis and both gene polymorphisms. Our findings suggest that MCP- 1 -2518 A>G and CCR2 V64I polymorphisms are not associated with genetic susceptibility to lung cancer and lung cancer metastasis.
