Abstract

The effect of polymorphic variants of the DNMT3B gene on the risk of non-small cell lung cancer (NSCLC) development and its clinical characteristics was assessed. To identify rs1569686 (–579G > T) and rs2424913 (–149C > T) polymorphisms in the promoter region of the DNMT3B gene, a PCR-RFLP method was used. The risk significance of –579GT + TT (OR = 1.73; 95% CI: 1.11–2.71) and –149 CT + TT (OR = 1.59; 95% CI: 1.00–2.50) in the development of a more common tumor process in the case of non-small cell lung cancer was shown. Individuals over 60 years with the –579TT DNMT3B genotype are subjects to an increased risk of non-small cell lung cancer development (OR = 2.49; 95% CI: 1.15–5.40) and squamous cell lung cancer (OR = 4.39; 95% CI: 1.36–14.13). It was found that among smoking patients compared with non-smoking patients, there are significantly more carriers of –149TT (OR = 2.39; 95% CI: 1.16–6.93) and –579TT (OR = 3.05; 95 % CI: 1.36–6.85) genotypes. The same dependence sustained in the case of smoking patients with squamous cell lung cancer.
