AbstractThe suspicion of acute myeloid leukemia (AML) is a haematological emergency that requires a rapid diagnostic workup. Symptoms are usually caused by cytopenias of all blood cell lines. The differentiation of acute promyelocytic leukemia (APL) is important because of the early death rate caused by thrombembolic and bleeding events. Rapid immunophenotypic and genetic characterization is necessary for risk stratification and therapy selection. For this purpose, a center with appropriate expertise should be contacted. Therapy has become more complex due to numerous new approvals. For certain patients, the established intensive induction therapy with cytarabine and anthracycline is now combined with targeted agents, like the antibody conjugate Gemtuzumab-Ozogamicin or the FLT3 inhibitor Midostaurin. Patients with secondary AML benefit from the liposomal chemotherapy combination CPX-351. Therapy with the hypomethylating agent Azacitidine and the BCL2-inhibitor Venetoclax (Aza/Ven) represents the standard for patients who are not fit for intensive therapy. Here, it is important to consider interactions with CYP3A4-effective drugs.In most cases, APL is treated "chemotherapy-free" with all-trans retinoic acid (ATRA) and arsenic trioxide (ATO). In high-risk patients, the combination of chemotherapy and ATRA is still standard.Moreover, maintenance therapies were (re)established as an important therapeutic element of post-remission therapy. For example, Midostaurin is used in patients with FLT3 mutations, as is the multikinase inhibitor sorafenib after allogeneic stem cell transplantation. In addition, oral azacitidine is available for non-allogeneic transplant eligible patients in first complete remission. These new drugs have improved prognosis and resulted in a more individualized therapy mostly driven by genetic aberrations. This development will continue in the next years and will significantly improve treatment options, especially for older patients.Thieme. All rights reserved.
