Abstract

A retrospective analysis of the database of patients with histologically verified serrated adenomas of the colon was carried out as part of an observational study. Inclusion criteria: patients with serrated colon adenomas who underwent a molecular genetic study to detect mutations and further sequencing 16 sRNAs of intestinal microbiota from January 2021 to October 2021. The exclusion criteria: patients with a primary tumor of the colon who had previously received complex treatment, who had accompanying pathologies of the other organs and systems, which did not allow for the planned examination. According to the results of the study, BRAF mutations are diagnosed in half of the cases in serrated adenomas and in one-third of cases - KRAS mutations. As a result of a comparative analysis of the intestinal microbiome of young patients with serrated colon adenomas with summary statistical data on the presence of bacteria in the intestines of people from the Russian population; promising markers were found for the development of effective approaches for the early diagnosis of colorectal cancer.
