Cancer Med 2024; 13:e6890. [PMID: 38164059 PMCID: PMC10807610 DOI: 10.1002/cam4.6890] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2023] [Revised: 12/03/2023] [Accepted: 12/17/2023] [Indexed: 01/03/2024] Open
Abstract
BACKGROUND AND OBJECTIVE Myelodysplastic syndromes (MDS) are myeloid neoplasms characterized by ineffective hematopoiesis due to stem cell abnormalities. Monosomy 7q aberrations are a common cytogenetic abnormality in MDS. Specifically, an unbalanced translocation der(1;7)(q10;p10) [der(1;7)] has been identified in MDS patients, which is a monosomy 7q aberration variant like -7/del(7q). However, knowledge of der(1;7)'s features remains limited. Existing studies have compared the clinical and genetic characteristics of der(1;7) to those of -7/del(7q) but yielded inconsistent findings. Accordingly, we conducted meta-analyses comparing der(1;7) to -7/del(7q). METHODS Publications were searched from the following databases up to January 10, 2023: Pubmed, Web of Science, Embase, Cochrane, and ClinicalTrials.gov. Eligible studies were assessed for risks of bias. Relevant data were extracted from included studies and analyzed using random-effects models. Publication bias was evaluated and sensitivity analyses were performed. RESULTS The comparative meta-analyses included 405 MDS patients with der(1;7) from nine studies. The analysis revealed that der(1;7) was associated with a greater male preponderance (86.1% vs. 68.3%, Odds Ratios (ORs) 2.007, p < 0.01) than -7/del(7q), lower platelets counts compared to del(7q), higher hemoglobin levels than -7, lower absolute neutrophil counts, and higher percentage of patients with non-excess blasts (66.9% vs. 41.3%, ORs 2.374, p = 0.01) in comparison with -7/del(7q). The der(1;7) existed more as a sole karyotype aberration (55.6% vs. 37.0%, ORs 2.902, p = 0.02), co-occurred more often with +8 (22.7% vs. 4.2%, ORs 5.714, p = 0.04) whereas less -5/del(5q) (1.5% vs. 41.3%, ORs 0.040, p < 0.01) and complex karyotype (7.3% vs. 54.8%, OR 0.085, p < 0.01). The der(1;7) was associated with higher frequencies of RUNX1 (40.8% vs. 12.3%, ORs 4.764, p < 0.01), ETNK1 (28.1% vs. 2.5%, ORs 42.106, p < 0.01) and EZH2 (24.8% vs. 6.9%, ORs 3.767, p = 0.02) mutations, but less TP53 mutation (2.4% vs. 45.3%, ORs 0.043, p < 0.01). Moreover, der(1;7) patients had longer time to progression (Hazard Ratios (HRs) 0.331, p = 0.02), better overall survival (OS) than -7 patients (HRs 0.557, p < 0.01), but similar OS with del(7q) patients (HRs 0.837, p = 0.37). CONCLUSION The findings revealed distinct clinical, cytogenetic, and molecular characteristics distinguishing der(1;7) from -7/del(7q), indicating der(1;7) defines a unique subtype within MDS with monosomy 7q. These findings support classifying der(1;7) as a separate MDS entity in future.

The multidisciplinary approach to eosinophilia. Front Oncol 2023; 13:1193730.

Abstract
Eosinophilic granulocytes are normally present in low numbers in the bloodstream. Patients with an increased number of eosinophilic granulocytes in the differential count (eosinophilia) are common and can pose a clinical challenge because conditions with eosinophilia occur in all medical specialties. The diagnostic approach must be guided by a thorough medical history, supported by specific tests to guide individualized treatment. Neoplastic (primary) eosinophilia is identified by one of several unique acquired genetic causes. In contrast, reactive (secondary) eosinophilia is associated with a cytokine stimulus in a specific disease, while idiopathic eosinophilia is a diagnosis by exclusion. Rational treatment is disease-directed in secondary cases and has paved the way for targeted treatment against the driver in primary eosinophilia, whereas idiopathic cases are treated as needed by principles in eosinophilia originating from clonal drivers. The vast majority of patients are diagnosed with secondary eosinophilia and are managed by the relevant specialty-e.g., rheumatology, allergy, dermatology, gastroenterology, pulmonary medicine, hematology, or infectious disease. The overlap in symptoms and the risk of irreversible organ involvement in eosinophilia, irrespective of the cause, warrants that patients without a diagnostic clarification or who do not respond to adequate treatment should be referred to a multidisciplinary function anchored in a hematology department for evaluation. This review presents the pathophysiology, manifestations, differential diagnosis, diagnostic workup, and management of (adult) patients with eosinophilia. The purpose is to place eosinophilia in a clinical context, and therefore justify and inspire the establishment of a multidisciplinary team of experts from diagnostic and clinical specialties at the regional level to support the second opinion. The target patient population requires highly specialized laboratory analysis and therapy and occasionally has severe eosinophil-induced organ dysfunction. An added value of a centralized, clinical function is to serve as a platform for education and research to further improve the management of patients with eosinophilia. Primary and idiopathic eosinophilia are key topics in the review, which also address current research and discusses outstanding issues in the field.

Abstract
OBJECTIVES To report the findings of the 2019 Society for Hematopathology/European Association for Haematopathology Workshop within the categories of reactive eosinophilia, hypereosinophilic syndrome (HES), germline disorders with eosinophilia (GDE), and myeloid and lymphoid neoplasms associated with eosinophilia (excluding entities covered by other studies in this series). METHODS The workshop panel reviewed 109 cases, assigned consensus diagnosis, and created diagnosis-specific sessions. RESULTS The most frequent diagnosis was reactive eosinophilia (35), followed by acute leukemia (24). Myeloproliferative neoplasms (MPNs) received 17 submissions, including chronic eosinophilic leukemia, not otherwise specified (CEL, NOS). Myelodysplastic syndrome (MDS), MDS/MPN, and therapy-related myeloid neoplasms received 11, while GDE and HES received 12 and 11 submissions, respectively. CONCLUSIONS Hypereosinophilia and HES are defined by specific clinical and laboratory criteria. Eosinophilia is commonly reactive. An acute leukemic onset with eosinophilia may suggest core-binding factor acute myeloid leukemia, blast phase of chronic myeloid leukemia, BCR-ABL1-positive leukemia, or t(5;14) B-lymphoblastic leukemia. Eosinophilia is rare in MDS but common in MDS/MPN. CEL, NOS is a clinically aggressive MPN with eosinophilia as the dominant feature. Bone marrow morphology and cytogenetic and/or molecular clonality may distinguish CEL from HES. Molecular testing helps to better subclassify myeloid neoplasms with eosinophilia and to identify patients for targeted treatments.
