Summary: Acute myeloid leukemia (AML) is a blood cancer caused by genetic mutations, chromosomal translocations, or molecular changes. These alterations accumulate in stem cells and progenitor cells, leading to the development of AML, which is prevalent in 80% of adult acute leukemias. Recurrent cytogenetic abnormalities serve as diagnostic and prognostic markers and also confer resistance to traditional treatments. Immunophenotyping can help characterize the surface antigens of AML cells, aiding in the understanding of their molecular and immunophenotypic alterations.

Summary: Targeting the interaction between leukemic cells and the microenvironment by inhibiting CD38 has the potential to enhance therapeutic efficacy in AML. However, while the anti-CD38 antibody daratumumab showed significant cytostatic efficacy in an in vitro model, it ultimately lacked robust anti-leukemic effects in vivo in a xenograft transplantation model.

Summary: This article summarizes the recent updates on molecular targeting agents and emerging gene-specific strategies. FLT3 and IDH inhibitors are being tested together with conventional chemotherapy in patients who are fit for treatment and those who are not eligible for intensive therapy. Other potential therapeutic strategies include targeting the menin-MLL complex pathway, downstream signaling molecule SYK, and developing next-generation p53 stabilizers. The TP53 mutation remains a challenge, but promising results have been observed with the anti-CD47 antibody magrolimab in combination with azacitidine in patients carrying the TP53 mutation.

Summary: Although most AML patients achieve CR after initial induction chemotherapy, residual leukemic cells may lead to relapse, with MRD serving as a prognostic marker. Molecular techniques like NGS offer a sensitive assessment of MRD markers, but face challenges such as limited sensitivity/specificity and difficulty in distinguishing mutations. Multiple studies have explored the association between MRD detection by molecular assays and AML relapse, highlighting limitations, challenges, and opportunities.

Summary: Secondary acute myeloid leukemia (s-AML) patients who undergo allogeneic stem-cell transplant (HSCT) have worse survival compared to de novo AML patients, particularly in those who achieve complete remission (CR) before transplant. Factors contributing to the poorer prognosis include an increased risk of relapse and non-relapse mortality. However, patients receiving MAC conditioning had comparable outcomes, regardless of leukemia ontogeny.

Summary: The MDS/MPN category includes diseases with both myelodysplastic and myeloproliferative features. The revised International Consensus Classification now requires the presence of increased peripheral blood cell counts and concomitant cytopenia for diagnosis. The use of modern gene sequencing has improved understanding of the biological characteristics and specific mutations of these diseases, which are now included in the diagnostic criteria for some MDS/MPN entities. This review highlights the changes in diagnostic criteria and provides practical guidance for diagnosis.

Summary: This retrospective study evaluated the clinicopathologic and immunohistochemical features of non-AML MN patients with NPM1 mutations. The study found that NPM1 mutated non-AML MN patients commonly had cytopenias, dysplasia, normal karyotype, mutations in multiple genes, and an unfavorable clinical outcome, including progression to AML. Immunohistochemistry can be a useful tool to predict NPM1 mutation, but genetic testing cannot be replaced by it.
