Routes and molecular mechanisms of central nervous system involvement in acute myeloid leukemia (Review).

Abstract

Acute myeloid leukemia (AML) is a predominant form of leukemia. Central nervous system (CNS) involvement complicates its diagnosis due to limited diagnostic tools, as well as its treatment due to inadequate therapeutic methodologies and poor prognosis. Furthermore, its incidence rate is unclear. The mechanisms of AML cell mobilization from the bone marrow (BM) to the CNS are not fully elucidated, and the molecular factors contributing to CNS infiltration are insufficiently recognized. The present review aimed to enhance the understanding of CNS involvement of AML and its impact on CNS. The latest research on the pathways and mechanisms facilitating AML cells to escape the BM and infiltrate the CNS was reviewed. Additionally, novel therapeutic strategies targeting specific molecules and genes for treating CNS involvement in AML were examined.
