Роль определения молекулярно-генетических маркеров в диагностике и прогнозировании течения заболеваний шейки матки

Роль определения молекулярно-генетических маркеров в диагностике и прогнозировании течения заболеваний шейки матки

Abstract

Проведено обследование и лечение 46 пациенток с различной патологией шейки матки (ШМ). Возраст обследованных варьировался от 21 до 72 лет, в среднем составив 37,4 ± 1,1 года. У 16 пациенток определена частота гиперметилирования генов N33, MLHI, p16 в образцах тканей ШМ при различных ее заболеваниях: при лейкоплакии выявлено гиперметилирование генов р16 (83% наблюдений), MLH1 (66%), N33 (33%), при дисплазии ШМ р16 (100%), MLH1 (100%), N33 (62%), при плоскоклеточном раке ШМ р16 (100%), MLH1 (50%), N33 (50%). В ходе наблюдения за больными с установленным гиперметилированием генов развитие рецидива заболевания при лейкоплакии ШМ зафиксировано в 50% случаев, при дисплазиях ШМ в 37,5%. В группе, состоявшей из 30 пациенток, у которых не было определено аномального метилирования генов в тканях ШМ, за время наблюдения рецидивов заболевания не обнаружено.

Forty-six patients with various cervix uteri (CU) diseases were examined and treated. The examinees age was 21 to 72 years (mean age 37.4 ± 1.1 years). In 16 patients, the rate of N33, MLH1, p16 gene hypermethylation was determined in the tissue samples of the CU in its various diseases: there was hypermethylation of the p16 (83%) and MLH1 (66%), and N33 (33%) genes in CU leukoplakia; the p16 (100%) and MLH1 (100%), and N33 (62%) genes in CU dysplasia, and the p16 (100%) and MLH1 (50%), and N33 (50%) genes in squamous cell carcinoma of the CU. A follow-up of patients with established gene hypermethylation revealed a recurrence in 50% of cases of CU leukoplasia and in 37.5% of cases of CU dysplasias. No recurrences were observed in a group of 30 patients without abnormal gene methylation in CU tissues during the follow-up.
