ГЕНЕТИЧЕСКИЕ МАРКЕРЫ РИСКА РАЗВИТИЯ ПОВЕРХНОСТНОГО И ИНВАЗИВНОГО РАКА МОЧЕВОГО ПУЗЫРЯ

To reveal possible associations of the polymorphic variants of the cytochrome P450 and enzymes glutathione-S-transferase genes with the risk for bladder cancer (BC), the authors analyzed the frequency of genotypes and alleles at the polymorphic loci of the CYP1A1 (A2454G), GSTM1 (del), and GSTP1 (A313G) genes in 208 patients diagnosed as having BC (104 patients with invasive BC and 104 with superficial BC) and in 367 patients without identified oncopathology. The *1A*2C (OR = 3.42) and *2C*2С (OR = 6.98) genotypes, *2C (OR = 3.73) allele of the CYP1A1 gene and the GG (OR = 2.53) genotype of the GSTP1 gene were ascertained to be genetic markers for a risk for BC. The presence of the *2C (OR = 1.69) allele of the CYP1A1 gene, the G (OR = 2.40) allele and the AG genotype (OR = 2.40) of the GSTP1 gene was associated with the invasive forms of BC. There were no substantial differences in the distribution of the frequency of genotypes of the GSTM1 gene between the samples of patients and healthy individuals.С целью выявления возможных ассоциаций полиморфных вариантов генов цитохрома P450 и ферментов глутатион-S-трансферазы с риском развития рака мочевого пузыря (РМП) нами проведен анализ частот встречаемости генотипов и аллелей полиморфных локусов генов CYP1A1 (A2454G), GSTM1 (del), GSTP1 (A313G) у 208 больных с диагнозом РМП (104 пациента с инвазивным и 104 – с поверхностным раком) и у 367 пациентов без выявленной онкопатологии. Установлено, что генетическими маркерами риска развития РМП являются генотипы *1A*2C (ОP 3,42) и *2C*2С (ОР 6,98), аллель *2C (ОР 3,73) гена CYP1A1, генотип GG (ОР 2,53) гена GSTP1. Наличие аллеля *2C (ОР 1,69) гена CYP1A1, аллеля G (ОР 2,40) и генотипа AG (ОР 2,40) гена GSTP1 ассоциировано с инвазивными формами РМП. Существенных различий в распределении частот встречаемости генотипов гена GSTM1 между выборками больных и здоровых не выявлено
