Treatment of minimal residual disease in myeloid malignancies after allo-HSCT with venetoclax-based regimens in patients ineligible for or failed in the immunotherapy
Yu WJ, Kong J, Zheng FM, Mo XD, Zhang XH, Xu LP, Zhang YY, Sun YQ, Jin J, Huang XJ and Wang Y
Relapse was the major cause of treatment failure in patients with myeloid malignancies after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Patients who still suffer from the disease while cannot be detected by morphological analysis can be identified by the minimal residual disease (MRD) monitoring. The most used first-line regimens for MRD are immunotherapies. However, for patients who were ineligible for or failed in first-line immunotherapies, options were limited.

Salinas J, Flores Y, Rojas P, Gutierrez C, Vidal M, Jara V, Campbell J, García MJ, Sandoval V, Vergara M, Ocqueteau M, Palacios F and Sarmiento M
Allogeneic hematopoietic stem cell transplantation (HSCT) is a curative treatment for several hematological diseases. Prospective and retrospective studies have associated myeloablative conditioning regimens with increased non-relapse mortality and less intense regimens with disease relapse, leading to similar overall survival rates. Analyze the experience with the different RIC schemes in patients transplanted for AML/MDS in our program. We retrospectively analyzed our program's reduced-intensity conditioning regimens (RIC) between 2012 and 2022 in patients with acute myeloid leukemia (AML) and myelodysplastic syndromes (MDS). During this period, 450 allogeneic stem cell transplantations were performed, of which 52 patients were treated with RIC for AML, mostly in men. The 3-year overall survival/progression-free survival rates were 52/53%, 51/57%, and 57/55% in the fludarabine-reduced intensity with total-body irradiation, Melphalan, and Busulfan, respectively ( = 0.89). The composite incidences of aGVHD III-IV, cGVHD, and admission to the critical patient unit were 21%, 25%, and 30%, respectively, without statistically significant differences according to the type of conditioning, but with a trend of greater ICU admission in patients who used melphalan-based conditioning. Our study found no differences in overall survival, progression-free survival, and complications between the most commonly used reduced-intensity conditioning regimens.

Association between autoimmune diseases and myelodysplastic syndrome:a Mendelian randomization study
Miao Z, Zhu W, Zhou Y and Chen H
: The relationship between different types of autoimmune diseases and myelodysplastic syndrome (MDS) is inconclusive. Therefore, we employed Mendelian randomization (MR) to examine whether genetically predicted susceptibility to ten autoimmune diseases is associated with the risk of MDS. Single nucleotide polymorphisms (SNPs) significantly associated with 10 autoimmune diseases were extracted from the summary statistics of European genome-wide association studies (GWAS). A two-sample MR analysis was performed using summary-level statistics sourced from GWAS datasets. Inverse-variance weighting (IVW), MR-Egger, and weighted median (WM) were further supported by several sensitivity analyses. Four autoimmune diseases showed genetical predisposition to MDS: rheumatoid arthritis (OR = 1.186,95% CI = 1.028-1.367, = 0.019), multiple sclerosis (OR = 1.247, 95% CI = 1.013-1.534, = 0.037), myasthenia gravis (OR = 1.326,95% CI = 1.010-1.742, = 0.042), and Hashimoto thyroiditis(OR = 1.519,95% CI = 1.008-2.290, = 0.046). Nevertheless, no similar causal relationship was found between the remaining seven autoimmune diseases and MDS. The accuracy and robustness of these findings were confirmed by sensitivity tests. We are the first to use MR analysis to explore the relationship between autoimmune diseases and MDS. The mechanism needs to be further explored.

First case of acute promyelocytic leukemia with TFG-RARA achieved complete remission treated with venetoclax and all-trans retinoic acid
Zhu L, Shi T, Liu Y, Zhao S, Wang H, Chen Z, Wang Y, Jin J, Tong H, You L and Zhu HH
Variant acute promyelocytic leukemia (vAPL) represents a certain type of APL case whose specific fusion proteins, which are relevant but atypical variants, may fail to be identified by polymerase chain reaction (PCR) and fluorescence in situ hybridization (FISH) and requires identification through next-generation sequencing (NGS) or RNA sequencing (RNA-seq). These patients often show insensitivity to arsenic trioxide (ATO) or all trans-retinoic acid (ATRA) and therefore exhibit unclear prognosis. Venetoclax (VEN), an oral small-molecule B-cell lymphoma 2 (BCL-2) inhibitor, demonstrates effectiveness and safety as a cytoreduction therapy for pediatric APL and has shown some promising effect on relapsed or refractory APL. However, only a few cases have been reported on the treatment of vAPL with a single drug or multiple drugs combined with VEN. Therefore, this study reported the first vAPL case with the TFG-RARA fusion gene, who achieved complete remission (CR) with oral administration of VEN and ATRA, and remained CR till submission. Our study indicated that VEN may have a good therapeutic effect and contribute to a better prognosis of vAPL and warranted further application among APL patients.

Combining azole antifungals with venetoclax plus azacitidine in patients with newly diagnosed acute myeloid leukemia
Zhong X, Wang J, Dai Y, Huang X, Liu J, Xiang B and Ma H
The combination of venetoclax (VEN) with hypomethylating agents (HMAs) improves survival in patients with acute myeloid leukemia (AML) and may cause neutropenia requiring combined antifungal therapy or prophylaxis. The inhibition of cytochrome P450 activity by azole antifungal agents leads to elevated blood concentrations of VEN. This study aimed to evaluate the efficacy and safety of venetoclax plus azacitidine (AZA) with azoles in newly diagnosed AML patients. The primary endpoints included complete remission (CR), complete remission with incomplete blood cell recovery (CRi), composite CR (CRc, CR + CRi), blood cell recovery time and incidence of infections. The CRc was 50.0% in the azole group and 56% in the nonazole group ( > 0.05). In the azole group, the median recovery times for patients with ANC >500 cells/mm and ANC >1,000 cells/mm were 19 and 25 days, respectively. For the nonazole group, the corresponding times were 16 and 19 days ( < 0.05). In the azole group, the median durations for patients with a PLT >50,000/mm and >100,000/mm were 18 and 20 days, respectively. For the nonazole group, the corresponding times were 16 and 19 days ( > 0.05). The incidences of fungal and bacterial infections were not significantly different (30.8% vs 26.1% and 50.0% vs 56.0%) ( > 0.05). The cost-effectiveness ratio of the azole group is lower. There was no significant difference between VEN + AZA with or without azole in terms of efficacy, infection, or partial hematological toxicity. However, the combination of azoles may prolong the neutrophil recovery time. Azole combination could reduce the amount of venetoclax and improve health economics.

A novel N7-Methylguanine-related gene signature for predicting prognosis in acute myeloid leukemia: bioinformatic analysis and experimental verification
Zhao R, Yang L, Liu C, Jiang R, Huang Q, Wang Q and Wu X
The involvement of N7-Methylguanine (m7G) RNA methylation regulators in the progression of different types of solid cancers in humans has been established. However, the specific impact of m7G-related genes on Acute myeloid leukemia (AML) remains uncertain. Our research aims to build a novel signature of M7Gs that could enhance our understanding of the molecular heterogeneity in leukemia. The RNA-seq and clinical data of patients with AML were acquired from the UCSC XENA website. Prognostic-related genes were selected using LASSO to construct a risk-scoring model. External datasets were utilized to validate the effectiveness of the model, and the mRNA expressions of candidate genes were measured using RT-qPCR. A prognostic model was developed using a risk-scoring approach based on three candidate genes (IFIT5, EIF4E2, and LARP1) and their respective risk coefficients. Multivariate Cox regression analysis revealed a significant association between the risk score and overall survival (<0.001). In both the experimental and validation cohorts, individuals classified as high risk exhibited a poorer prognosis. The 5-year area under the curve (AUC) was calculated as 0.715 for the TCGA-LAML cohort and 0.646 for GSE37642. Additionally, analysis using ssGSEA demonstrated that the high-risk group exhibited higher levels of immune cell infiltration compared to low-risk group. RT-qPCR results indicated that the expression levels of LARP1, EIF4E2 and IFIT5 were consistent with the results of the bioinformatic analysis. In summary, the m7G-related genes are potential prognostic biomarkers for patients with AML.
