Abstract:
AIM:Toinvestigatetheinteractionofpolymorphismsofintercellularadhesionmolecule-1(ICAM-1) gene K469E and monocyte chemoattractant protein-1 (MCP-1) gene -2518A/G in the invasion and metastasis of gas-tric carcinoma .METHODS:Based on TNM classification , 4 500 patients with confirmed gastric carcinoma from the First Affiliated Hospital of Xinxiang Medical University in China from December 2009 to November 2014 were divided into stageⅠ group, stageⅡgroup, stageⅢgroup, stageⅣgroup, and stage 0 group, with 900 cases in each group.No significant difference among the 5 groups in age, gender, ethnicity, birthplace and living habit was observed .The genetic polymor-phisms of ICAM-1 gene K469E and MCP-1 gene -2518A/G were analyzed by the technique of polymorphism-polymerase chain reaction ( PCR) in peripheral blood leukocytes of above-mentioned cases .RESULTS:Statistical tests showed signi-ficant differences in the frequencies of K469E (EE) and -2518A/G (GG) among each group (P<0.01).The risk of the invasion and metastasis of gastric carcinoma significantly increased in subjects with K 469E ( EE) genotype and in those with -2518A/G (GG) genotype.Combined analysis of the polymorphisms showed that distribution frequency of K 469E (EE)/-2518A/G ( GG) in stage Ⅰ group, stage Ⅱ group, stage Ⅲ group, stage Ⅳ group and stage 0 group was 39.22%, 53.22%, 59.22, 65.44%and 12.11%, respectively (P<0.01).The people who carried with K469E (EE)/-2518A/G ( GG) had a high risk of the invasion and metastasis of gastric carcinoma , and statistical analysis suggested a positive interaction in a super-multiplicative model between K469E (EE) and -2518A/G (GG) in increasing the risk of the invasion and metastasis of gastric carcinoma .CONCLUSION: ICAM-1 gene K469E ( EE) and MCP-1 gene-2518A/G ( GG) are the risk factors in the invasion and metastasis of gastric carcinoma , and significant interactions be-tween genetic polymorphisms of K 469E and -2518A/G added the risk of the invasion and metastasis of gastric carcinoma .
