Possibilities of Cytogenetic Studies in Acute Myeloid Leukemia (Literature Review)
Abstract
The article presents a literature review of the cytogenetic aspects of diagnosis and monitoring of acute myeloid leukemia. It provides a detailed analysis of the nature of acute myeloid leukemia, its prevalence, and the possibilities of studying the morphological, immunological, and molecular genetic characteristics of blast cells. Cytogenetic methods of standard karyotyping and fluorescent in situ hybridization allow for the detection of recurrent and unique chromosomal abnormalities that lead to changes in the structure and expression of oncogenes and tumor suppressor genes, which has diagnostic and prognostic significance. The modern classification of acute myeloid leukemia is based on the morphological, immunophenotypic, and genetic features of blast cells. Identification of genetic markers - recurrent chromosomal rearrangements and gene mutations - allows for the determination of acute myeloid leukemia subtypes with favorable, unfavorable, and intermediate prognoses.
