Abstract:
Objective To study the relationship between monoeyte chemoattractant protein 1 (MCP-1)-2518A/G polymorphism and lung cancer in Han nationality of North China. Methods One hun-dred and thirty-four unrelated consecutive patients with lung cancer(112 with NSCLC, 22 with SCLC)and 82 healthy individuals were studied. The polymorphisms of MCP-1-2518A/G were detected with polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP). Results The distribution of AA, AG and GG genotypes of MCP-1-2518 was significantly different in lung cancer patients compared with controls (X~2=8. 486,P=0. 014). There was a significant increase in the frequency of the AA genotype (OR=2. 645, X~2=6. 532, P=0.011) and a significant decrease in the frequency of the GG genotype (OR=0.519, X~2=4.929, P=0. 026)in the lung cancer patients, compared with controls. In the NSCLC patients the fre-quency of the AA genotype was higher than controls(OR=3. 138, X~2=8. 905, P=0.003) and the frequency of the GG genotype was lower than controls(OR=0. 516 ,X~2=4. 613, P=0. 032). The frequencies of AA, AG and GG genotypes in SCLC patients and controls had no difference. Conclusion This preliminary study showed that MCP-1-2518A/G polymorphism was associated with NSCLC but not SCLC.
