In this issue of Cancer Cell, Pan et al. show that a combination therapy designed to reactivate the p53 tumor suppressor while antagonizing the anti-apoptotic function of Bcl-2 is highly active in preclinical models of refractory acute myeloid leukemia (AML). The results may move the needle in this hard-to-treat malignancy.

Outcome for acute myeloid leukemia (AML) patients aged >60 years is poor. Targeting the proteasome in AML is attractive, since leukemia stem cells demonstrate sensitivity to proteasome inhibition in preclinical models. Adults >60 years of age with newly diagnosed AML were enrolled.

Introduction: Antibody-based immunotherapies are a class of therapeutics under active investigation in clinical trials for the treatment of acute myeloid leukemia (AML). Our review provides a comprehensive examination of trials published to date, focusing on recurrent challenges and promising aspects of antibody-based therapeutics.
Areas Covered: We described antibody-based immunotherapies for AML, specifically, an overview of the most prominent antigen targets in published clinical trials investigating monoclonal antibodies, antibody-drug conjugates, bispecific antibodies, and chimeric antigen receptor therapies.
Donor Lymphocyte Infusion (DLI) is a crucial therapeutic strategy for relapsed myeloid malignancies post-allogeneic hematopoietic cell transplantation (allo-HCT), leveraging the graft-versus-leukemia (GvL) effect to restore immune control. While highly effective in chronic myeloid leukemia (CML), its efficacy in acute myeloid leukemia (AML) remains limited, with underlying mechanisms not fully understood. Recent research by Maurer and colleagues utilized cutting-edge technologies to dissect immune-leukemia interactions within the bone marrow niche, identifying a cytotoxic CD8+ T cell population as a key mediator of the anti-leukemic response.

Alterations in the tumor suppressor gene TP53 are common in human cancers and are associated with an aggressive nature. Approximately 8%-12% of myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML) harbor TP53 mutations (TP53) and present immense challenges due to inherent chemoresistance and poor outcomes. As TP53 are more common in older individuals and those with secondary/therapy-related myeloid neoplasms (MN), their incidence is expected to increase with an aging population and rising proportion of cancer survivors.

We present a case of acute clonal bone marrow 98% infiltration of atypical myeloid cells with borderline hypogranular/agranular promyelocytes/myelocytes and occasional blast cells maturity, which also formed extramedullary tumours in the chest wall, with isolated trisomy of chromosome 6 and pathogenic variant U2AF1 (S34F) that escapes established acute myeloid leukaemia (AML) diagnostic criteria according to the World Health Organization (WHO) classification. Following standard daunorubicin and cytarabine induction therapy, the disease progressed with the appearance of a previously undetected clone of leukaemic cells with a distinct immunophenotype demonstrating monocytoid differentiation and clonal evolution to a hypo-tetraploid karyotype with an average number of 84 chromosomes and new pathogenic NRAS and ZRSR2 mutations. The patient reactivated refractory disseminated intravascular coagulation (DIC) leading to a progressive supratentorial hematoma and finally cardiac arrest.
