ABSTRACT
Objective To study the interaction of genetic polymorphisms of CYP2E1 and environmental hazard factors in gastric cancer. Methods 1∶1 case-control study was carried out in Nanjing area, using PCR-RFLP technology to determined the genetic polymorphisms of CYP2E1 and epidemiological data about environmental exposure of 121 cases and controls were collected. Interaction indexes (?) were calculated to determine the type of gene-environment interaction. Results After confounding adjusted, the result showed that interaction existed in genetic polymorphisms of CYP2E1 RsaⅠand the family history of digestive system disease, smoking, pickled food, irregular diet habit, interaction indexes (?) value were 1.855, 2.626, 1.736 and 1.714 respectively. A low exposure-gene effect interaction was found in CYP2E1 RsaⅠgenotype and the frequency of pickled food consumed, while a high exposure-gene effect interaction exist in CYP2E1 RsaⅠgenotype and irregular diet habit. Conclusion Genetic and environmental hazard factors co-effect the development of gastric cancer, genetic polymorphisms of CYP2E1 and environmental risk factors show an interaction in gastric cancer.
