The advent of all-trans retinoic acid (ATRA) and arsenic trioxide (ATO) has revolutionized the treatment of acute promyelocytic leukemia (APL), resulting in excellent rates of remission and long-term survival. However, real-world outcomes often fall short of those observed in clinical trials due to various factors related to patient demographics and clinical practices. This review examines APL treatment outcomes in real-world settings and highlights the phenomenon of APL clusters.

In the randomized phase III IDHENTIFY trial, the IDH2 inhibitor enasidenib (ENA) showed improvement in event-free but not overall survival compared with conventional care regimens (CCR) among patients with relapsed/refractory (R/R), -mutant AML. We constructed a partitioned survival model to evaluate the cost-effectiveness of enasidenib for the treatment of older patients with R/R, and -mutant AML. In the base-case scenario, ENA exhibited an incremental effectiveness of 0.

Clinical trials are crucial for improving patient outcomes. Although a significant number of trials are discontinued prematurely, our understanding of factors influencing early termination is limited. We conducted a comprehensive search of ClinicalTrials.

Article Synopsis
  • * Treatment for lower-risk MDS focuses on improving quality of life and may include therapies like erythropoiesis-stimulating agents and new medications like imetelstat, while higher-risk MDS often utilizes hypomethylating agents as standard care, with ongoing research into combination therapies.
  • * Despite advancements in treatment options, especially for higher-risk MDS, challenges remain due to limited effective therapies after initial treatment failures, highlighting the need for new drug developments that could change current treatment approaches.

Article Synopsis
  • Myelodysplastic syndromes (MDS) are a diverse group of blood cancers divided into high-risk (HR-MDS) and low-risk (LR-MDS), with different management strategies for each.
  • Historically, LR-MDS has been treated with supportive care and erythropoiesis-stimulating agents, while HR-MDS often requires more aggressive treatments like hypomethylating agents and stem cell transplants.
  • The text discusses current research into targeted therapies for MDS, noting the progress made but also the ongoing challenges in developing effective treatments and the importance of better understanding the disease's biology.

Article Synopsis
  • Quizartinib, an FLT3 inhibitor, boosts overall survival for newly diagnosed AML patients aged 18-75 with an ITD mutation when combined with intensive chemotherapy ("7 + 3").
  • A cost-effectiveness analysis revealed that adding quizartinib to standard treatment incurs additional costs of $289,932, yielding only 0.84 more quality-adjusted life years (QALYs).
  • The incremental cost-effectiveness ratio stands at $344,039/QALY, suggesting quizartinib would only be considered cost-effective with substantial price reductions or specific treatment adjustments.

Purpose Of Review: Myelodysplastic syndromes/neoplasms (MDS) represent a diverse group of pathologically distinct diseases with varying prognoses and risks of leukemia progression. This review aims to discuss current treatment options for elderly patients with MDS, focusing on patients ineligible for intensive chemotherapy or allogenic hematopoietic stem cell transplantation (HSCT). The challenges associated with treatment in this population and emerging therapeutic prospects are also explored.

PHF6 mutations (PHF6) are identified in various myeloid neoplasms (MN). However, little is known about the precise function and consequences of PHF6 in MN. Here we show three main findings in our comprehensive genomic and proteomic study.

Myelodysplastic syndromes/neoplasms (MDS) are a heterogeneous group of hematopoietic cancers characterized by recurrent molecular alterations driving the disease pathogenesis with a variable propensity for progression to acute myeloid leukemia (AML). Clinical decision making for MDS relies on appropriate risk stratification at diagnosis, with higher-risk patients requiring more intensive therapy. The conventional clinical prognostic systems including the International Prognostic Scoring System (IPSS) and its revised version (IPSS-R) have dominated the risk stratification of MDS from 1997 until 2022.

Background: Splenectomy is commonly used to treat refractory immune-mediated cytopenia, but there are no established factors that are associated with response to the procedure.

Objectives: A cohort study was conducted to evaluate the hematologic and surgical outcomes of splenectomy in adult patients with immune cytopenias and identify preoperative factors associated with response.

Methods: Data from the Cleveland Clinic Foundation for 1824 patients aged over 18 who underwent splenectomy from 2002 to 2020 were analyzed.

Article Synopsis
  • * Researchers conducted a detailed analysis of over 600 MN samples to better understand the biology of -7/del7q and identify genes involved in leukemia development.
  • * They identified 27 potential synthetic lethal target genes that could be used for new treatments, along with 26 genes that are up or down-regulated, providing insights and possible therapeutic strategies for -7/del7q myeloid neoplasms.

Background: Monomorphic ventricular tachycardia (VT) electrical storm (ES) in patients with coronary artery disease is dependent on scarred myocardium. The role of routine ischemic or coronary evaluations before ablation in patients presenting with monomorphic VT storm, without acute coronary syndrome (ACS), remains unknown.

Objectives: This study sought to assess the impact of ischemic or coronary evaluations on procedural outcomes and post-ablation mortality in monomorphic VT storm patients.

Background: TP53 mutations (TP53) occur in diverse genomic configurations. Particularly, biallelic inactivation is associated with poor overall survival in cancer. Lesions affecting only one allele might not be directly leukemogenic, questioning the presence of cryptic biallelic subclones in cases with dismal prognosis.

Isolated chronic idiopathic neutropenia (CIN) is a rare disease with multiple contributing etiologies that must be ruled out before establishing a diagnosis. We studied clinical and molecular data of 238 consecutive adult patients with CIN. Autoimmune neutropenia was present in 28% of our cohort.
