    HSPA9/mortalin inhibition disrupts erythroid maturation through a TP53-dependent mechanism in human CD34+ hematopoietic progenitor cells. (PubMed, Cell Stress Chaperones)
    We showed that inhibition of HSPA9 disrupts erythroid maturation in human CD34+ hematopoietic progenitor cells, through a TP53-dependent mechanism. Our findings not only indicate that reduced levels of HSPA9 may contribute to anemia observed in del(5q)-associated MDS patients, but also provide new insights into potential mechanisms of anemia.

    Myelodysplasia-related gene mutations are associated with favorable prognosis in patients with TP53-mutant acute myeloid leukemia. (PubMed, Ann Hematol)
    The complete response rates for intensive chemotherapy (IC), hypomethylating agent (HMAs)-based therapies, and azacitidine plus venetoclax were 35.7%, 22.2%, and 37.5%, respectively. In conclusion, patients with TP53-mutant AML have poor prognoses under current treatment strategies and MR gene mutations are associated with a more favorable survival. Therefore, further studies are needed to improve the survival rates in this population.

    DELE1 haploinsufficiency causes resistance to mitochondrial stress-induced apoptosis in monosomy 5/del(5q) AML. (PubMed, Leukemia)
    Here, we showed that the partial loss of DELE1 expression observed in -5/del(5q) patients was sufficient to significantly reduce the sensitivity to mitochondrial stress in AML cells. Overall, our results suggest that DELE1 haploinsufficiency could represent a new driver mechanism in -5/del(5q) AML.

    Pulmonary infection associated with immune dysfunction is associated with poor prognosis in patients with myelodysplastic syndrome accompanied by TP53 abnormalities. (PubMed, Front Oncol)
    The complete response rates for azacitidine monotherapy, venetoclax combined with azacitidine, decitabine monotherapy, and decitabine combined with low-dose chemotherapy were 9.1%, 41.7%, 37.5%, and 33.3%, respectively. In conclusion, TP53 abnormalities in patients with MDS were frequently accompanied by complex karyotypes, and treatments based on hypomethylating agents or venetoclax have limited efficacy. Pulmonary infections associated with immune dysfunction is associated with poor prognosis.

    A karyotype on bone marrow remains mandatory at diagnosis of MDS with complementary molecular analyses now required. Analyses with FISH or other technologies providing similar information can be necessary to complete and help in case of karyotype failure, for doubtful CA, for clonality assessment, and for detection of TP53 deletion to assess TP53 biallelic alterations.

    Identification of Vulnerabilities for Pharmacological Inhibition of PIP4K2s in Acute Myeloid Leukemia (ASH 2023)
    Kasumi-1, NB4 and U-937 cells were treated with vehicle or increasing concentrations of THZ-P1-2 and/or venetoclax for 48h... Our study characterized the expression of PIP4K2s in the myeloid compartment of hematopoietic cells, as well as in different molecular subsets of AML. The identification of the correlation between the expression of PIP4K2s and the response to antineoplastic agents in ex vivo assays in AML exposed vulnerabilities that can be exploited in combined therapies, which could result in better therapeutic responses.

    Recent findings in myelodysplastic syndrome (PubMed, Dtsch Med Wochenschr)
    The IPSS-M also represents an important extension with regard to prognosis estimation for patients with therapy-related MDS.In 2020 Luspatercept has been approved for transfusion-dependent lower risk MDS patients harboring ring sideroblasts ± an SF3B1 mutation after failure of an erythropoiesis stimulating agent. In addition, data from the phase III trial with Imeltelstat give reason to hope that we will be able to offer a new second-line therapy to LR-MDS patients. For higher risk MDS patients azacitidine therapy remains the standard of care, results of phase III trials of combination therapies must be awaited.

    Comparison of the Revised 4 Th (2016) and 5 Th (2022) Editions of the World Health Organization (WHO) Classification in a Cohort of Patients with Lower-Risk Myelodysplastic Syndromes/Neoplasms (MDS) – a Glam Registry (REGLAM) Analysis (ASH 2023)
    Our study, to our knowledge, provides one of the first, if not the first, datasets from LMIC to describe characteristics of IPSS-R lower-risk MDS pts and their re-classification and corresponding survival according to the WHO 2016 and 2022 classifications. Limited availability of molecular analysis in real-life settings (e.g., TP53 mutations) highlights some of the challenges of using the 2022 WHO classification (as well as IPSS-M) LMIC. Understanding the epidemiology of MDS pts in LMIC is important especially as some of the newly approved agents for lower risk MDS are starting to be used in these countries.

    Outcomes for Children with High Risk Acute Myeloid Leukemia on the Myechild 01 International Phase III Clinical Trial (ASH 2023)
    The MyeChild 01 international phase III trial (NCT02724163) in children with de novo AML allocated patients up to 3 doses of gemtuzumab ozogamicin (GO 3mg/m2/dose) during the first course of induction chemotherapy (mitoxantrone 12 mg/m2/dose x4; cytarabine 100 mg/m2/dose x20). Two intensive courses of induction chemotherapy, including GO and mitoxantrone in course 1 and FLA-Ida in course 2, consolidated with allogeneic HSCT, appears to be an effective approach for most HR patients. 2 year estimated outcomes for HR patients compare favourably to recent trials of GO in pediatric AML, with particularly encouraging data for patients with KMT2A-r and FLT3-ITD.

    Clinical and Molecular Characterization of Patients with Therapy Related Myeloid Neoplasms (TRMN) (ASH 2023)
    Our results highlight the role of mutations in cancer predisposition genes in the development of TRMN. Similar latency associations were found for TRMN and nTMN patients, which suggest that other risk factors different than treatment might contribute to the TRMN development. Altered karyotypes in TRMN patients are associated with acquired mutations in myeloid genes but not with germline mutations, which suggests two different entities with different prognosis.

In sum, genotyping with nanoranger substantially augmented scRNA-seq analyses of ipilimumab-based therapy in bone marrow AML. This exemplifies the great potential that long-read sequencing-based single cell studies hold to better define response and resistance mechanisms of novel immunotherapies.

    Modification of the ELN Classification 2022 Refines Risk Assessment in MDS/AML Patients (ASH 2023)
    For MDS/AML patients, AML-based risk classification according to ELN 2022 guidelines is not applicable as the vast majority of cases are categorized into the adverse risk group based on mutations in splicing factor genes and other secondary-type mutations. Modification of the ELN risk categories reflects the partly MDS-based biology of the disease and substantially improves the prognostic stratification. Most importantly, patients with adverse outcome potentially benefitting from inclusion into clinical trials for novel substances are identified.

    A Case of Acute Myeloid Leukemia with EWSR1::FLI1 Fusion (AMP 2023)
    He started therapy with azacitidine and venetoclax and achieved morphologic remission, measurable residual disease positive (<0.01%). Deletion of chromosome 11q is a rare chromosomal lesion in myeloid malignancies. As the mixed lineage leukemia (MLL) gene is located at the long arm of chromosome 11, it is commonly associated with poor prognosis, especially in therapy-related settings. Although no MLL rearrangement was detected in our case, the multiple relapses and persistent disease despite chemotherapy might be potentially due to having additional EWSR1::FLI1 fusion.
