[Association of polymorphic markers Arg72Pro of TP53 and T309g of MDM2 genes with non small cell lung cancer in Russians of Moscow region].

ABSTRACT

State Research Center "GosNIIgenetika", Moscow, 117545 Russia). Association of polymorphic markers Arg72Pro of TP53 gene and T309G of MDM2 gene with risk of non small cell lung cancer has been studied in Russians of Moscow region. We found an association of minor Pro/Pro genotype of polymorphic marker Arg72Pro (OR = 5.46, p = 8 x 10(-6)) and TG genotype of polymorphic marker T309G (OR = 5.57, p = 0.007) with non small cell lung cancer development. We have also showed a strong association of both Pro/Pro and TG genotypes with development of adenocarcinoma (OR = 8.71, p = 3 x 10(-6) and OR = 8.13, p = 0.003) and squamous-cell lung cancer (OR = 4.2, p = 0.001 and OR = 7.02, p = 0.002). We have finally found highly reliable association of combined susceptible genotypes of polymorphic markers Arg72Pro and T309G of TP53 and MDM2 genes with non small cell lung cancer and both its subtypes (OR = 7.9, p = 0.01; OR = 9.12,p = 0.02; OR = 7.31, p = 0.03, respectively).
