Stratified treatment of fit and unfit acute myeloid leukemia

Abstract

The etiology and pathogenesis of acute myeloid leukemia (AML) have been elucidated at chromosomal and genetic levels. The classification and prognosis for its treatment has clearly involved specific chromosomal aberrations and genetic mutations. The recent comprehensive genomic analysis represented by next-generation sequencers has led to discovering new genetic mutations in AML. These findings have not only been applied clinically as prognostic factors and MRD markers but also contributed to the development of new molecular-targeting drugs. Many new drugs have already been approved in the USA and Europe, and new stratified treatments have tried to incorporate them. With the advent of venetoclax, treatment strategies, especially for patients with poor prognosis and who are unfit, have been substantially revised, and the maintenance therapy for AML is also being reevaluated in accordance to the National Comprehensive Cancer Network guidelines. This article will review the current status of AML treatment in Japan and according to Western guidelines.
