The present review focuses on the current management of patients with chronic myelomonocytic leukemia (CMML) and the most recent developments in the field.


Comparison of Tumor Staging Systems for Cutaneous Squamous Cell Carcinoma in Patients with Chronic Lymphocytic Leukemia.

Patients with chronic lymphocytic leukemia (CLL) are at increased risk for poor outcomes as a result of cutaneous squamous cell carcinoma (CSCC).

Characterization of chronic myelomonocytic leukemia with TP53 mutations.


KMT2A-rearranged infantile acute myeloid leukemia masquerading as juvenile myelomonocytic leukemia.

Mixed lineage leukemia [MLL; now known as lysine methyltransferase 2A (KMT2A)] rearrangement-positive acute myeloid leukemia (AML) and juvenile myelomonocytic leukemia (JMML) are distinct diseases, although age of susceptibility (infancy or early childhood) and abnormal monocytosis are common clinical features. Here, we report two cases of KMT2A-rearranged infantile AML masquerading as JMML at initial presentation. Both cases showed leukocytosis accompanied by atypical monocytosis. However, in both cases, l...

Generation of a human Juvenile myelomonocytic leukemia iPSC line, CHOPi001-A, with a mutation in CBL.

Juvenile myelomonocytic leukemia (JMML) is a rare myeloproliferative disorder of early childhood characterized by expansion of clonal myelomonocytic cells and hyperactive Ras/MAPK signaling. The disorder is caused by somatic and/or germline mutations in genes involved in the Ras/MAPK and JAK/STAT signaling pathways, including CBL. Here we describe the generation of an iPSC line with a homozygous CBL c.1111T->C (Y371H) mutation, designated CHOPJMML1854.

Genomic aberrations involving 12p/ETV6 are highly prevalent in blastic plasmacytoid dendritic cell neoplasms and might represent early clonal events.

Chromosomal aberrations at the ETV6 gene locus on 12p13.2 are common in bone marrow samples involved by blastic plasmacytoid dendritic cell neoplasm (BPDCN). However, their pathogenic role, incidence in cutaneous BPDCN lesions, and clinical significance have not been assessed systematically.

Targeting cell-bound MUC1 on myelomonocytic, monocytic leukemias and phenotypically defined leukemic stem cells with anti-SEA module antibodies.

Cell surface molecules aberrantly expressed or overexpressed by myeloid leukemic cells represent potential disease-specific therapeutic targets for antibodies. MUC1 is a polymorphic glycoprotein whose cleavage yields two unequal chains: a large extracellular α subunit containing a tandem repeat array bound in a strong non-covalent interaction to a smaller β subunit containing the transmembrane and cytoplasmic domains. Because the α chain can be released from the cell-bound domains of MUC1, agents directe...

Emerging utility of flow cytometry in the diagnosis of chronic myelomonocytic leukemia.

The diagnosis of many hematologic malignancies has shifted from being based almost exclusively on morphology and clinical data to include ancillary studies such as flow cytometry. This trend has yet to affect the diagnosis of chronic myelomonocytic leukemia (CMML) as flow cytometry, while being integral in the diagnosis of many hematologic malignancies, has no explicit role in the current WHO criteria for CMML. The absence of WHO-determined criteria for flow cytometry in the diagnosis of CMML is not due to ...

The yin-yang of the interaction between myelomonocytic cells and NK cells.

NK cells are innate lymphoid cells, which play a key role in the immune response to cancer and pathogens and participate in the shaping of adaptive immunity. NK cells engage in a complex bidirectional interaction with myelomonocytic cells. In particular, macrophages, dendritic cells and neutrophils promote differentiation and effector function of NK cells and, on the other hand, myelomonocytic cells express triggers of checkpoint blockade (e.g. PD-L1) and other immunosuppressive molecules, which negatively ...

Comprehensive mutation profiling and mRNA expression analysis in atypical chronic myeloid leukemia in comparison with chronic myelomonocytic leukemia.

Atypical chronic myeloid leukemia (aCML) and chronic myelomonocytic leukemia (CMML) represent two histologically and clinically overlapping myelodysplastic/myeloproliferative neoplasms. Also the mutational landscapes of both entities show congruencies. We analyzed and compared an aCML cohort (n = 26) and a CMML cohort (n = 59) by next-generation sequencing of 25 genes and by an nCounter approach for differential expression in 107 genes. Significant differences were found with regard to the mutation freq...

Clinical and molecular characterization of early T-cell precursor acute lymphoblastic leukemia: Two cases report and literature review.

Early T-cell precursor acute lymphoblastic leukemia (ETP-ALL) is a small subtype of T-cell acute lymphoblastic leukemia with a typical immune-phenotype: lack of T-lineage cell surface markers CD1a and CD8 expression, weak or absent CD5 expression, at least one of the myeloid or hematopoietic stem cell markers. It is characterized by high rate of induction failure and the effective unified treatment strategies are still indeterminate. We present 2 ETP-ALL cases.

A case report of extranodal NK/T-cell lymphoma in patient with chronic lymphocytic leukemia.

Chronic lymphocytic leukemia often results in secondary tumors, the most common being large B cell lymphoma known as Richter syndrome, followed by extranodal NK/T-cell lymphoma (nasal type) is extremely rare.

Chronic Myelomonocytic Leukemia Mimicking Invasive Fungal Rhinosinusitis.

Analysis of four types of leukemia using Gene Ontology term and Kyoto Encyclopedia of Genes and Genomes pathway enrichment scores.

Leukemia is the second common blood cancer after lymphoma, and its incidence rate has an increasing trend in recent years. Leukemia can be classified into four types: acute lymphoblastic leukemia (ALL), acute myeloid leukemia (AML), chronic lymphocytic leukemia (CLL), and chronic myelogenous leukemia (CML). More than forty drugs are applicable for different types of leukemia based on the discrepant pathogenesis. Therefore, the identification of specific drug-targeted biological processes and pathways is hel...

Dendritic cells promote the spread of human T-cell leukemia virus type-1 via bidirectional interactions with CD4 T-cells.

Human T-cell leukemia virus type-1 (HTLV-1) propagates within and between individuals via cell-to-cell transmission, and primary infection typically occurs across juxtaposed mucosal surfaces during breastfeeding and sexual intercourse. It is therefore likely that dendritic cells (DCs) are among the first potential targets for HTLV-1. However, it remains unclear how DCs contribute to virus transmission and dissemination in the early stages of infection. We show that an HTLV-1-infected cell line (MT-2) and na...

Utility of JAK2 V617F allelic burden in distinguishing chronic Myelomonocytic leukemia from primary myelofibrosis with Monocytosis.

The concurrent presence of JAK2 V617F, monocytosis and bone marrow fibrosis can be observed in both chronic myelomonocytic leukemia (CMML) and primary myelofibrosis (PMF). It can be challenging to distinguish CMML with JAK2 mutation and fibrosis from other myeloid neoplasms, particularly PMF. To identify key features that may help distinguish these two entities, we retrospectively studied 21 cases diagnosed as "CMML" with JAK2 V617F and bone marrow fibrosis that were identified from a cohort of 610 cases of...

Genetic compensation of RUNX family transcription factors in leukemia.

RUNX1 is a transcription factor belonging to the Core Binding Factor (CBF) family. It is considered to be a master regulator of hematopoiesis and has been regarded as a tumor suppressor because it is essential for definitive hematopoiesis in vertebrates. It is one of the most frequent target genes of chromosomal translocation in leukemia, and germ line mutation of RUNX1 causes familial platelet disorder with associated myeloid malignancies (FPDMM). Somatic cell mutations and chromosomal abnormalities, inclu...

Antigen-Presenting Cell Characteristics of Human γδ T Lymphocytes in Chronic Myeloid Leukemia.

Human γδ T lymphocytes play a role in the immune system defense against cancer. Their broad anti-cancer activity against different types of cancers makes them outstanding candidates for cancer immunotherapy. An issue of recent interest is whether their antigen presentation features are similar to mature dendritic cells. The antigen-presenting cell (APC)-like phenotype and function of γδ T lymphocytes have been confirmed in many clinical trials. In this study, to support the strong role played by Vγ9Vδ...

Histiocytic Sarcoma: Review, Discussion of Transformation From B-Cell Lymphoma, and Differential Diagnosis.

Histiocytic sarcoma is a rare neoplasm of mature histiocytes with an aggressive clinical course that can arise de novo or from a low-grade B-cell lymphoma. In particular, chronic lymphocytic leukemia/small lymphocytic lymphoma is a very common malignancy in the Western hemisphere, and most cases of chronic lymphocytic leukemia/small lymphocytic lymphoma have an indolent course and behavior. However, 2% to 8% of chronic lymphocytic leukemia/small lymphocytic lymphoma cases transform. Histiocytic sarcomatous ...

Progressive kidney failure in chronic myelomonocytic leukaemia: don't forget lysozyme damage.

Kidney failure is common in haematologic malignancies. However, the nephrotoxic effect of lysozyme is seldom recognized. We present a 78-year-old male with chronic myelomonocytic leukaemia who developed progressive kidney failure due to increased production of lysozyme.

Epidemiology and survival of blastic plasmacytoid dendritic cell neoplasm.

Galectins as potential emerging key targets in different types of leukemia.

Galectins are carbohydrate-binding proteins and these have very high affinity for β-galactoside containing glycoproteins and glycolipids. Amongst sixteen types of galectin, the role of galectin 1, 3, 9 and 12 is defined in the development and progression of different types of leukemia including acute myeloid leukemia, acute promyelocytic leukemia, B-cell precursor acute lymphoblastic leukemia, adult T cell leukemia and chronic lymphocytic leukemia. There are multiple mechanisms through which these galectin...

Immunotherapy in acute myeloid leukemia and myelodysplastic syndromes: The dawn of a new era?

Immunotherapy has revolutionized therapy in both solid and liquid malignancies. The ability to cure acute myeloid leukemia (AML) and myelodysplastic syndromes (MDS) with an allogeneic hematopoietic stem cell transplant (HSCT) is proof of concept for the application of immunotherapy in AML and MDS. However, outside of HSCT, only the anti-CD33 antibody drug conjugate gemtuzumab ozogamicin is currently approved as an antibody-targeted therapy for AML. Several avenues of immunotherapeutic drugs are currently in...

Allogeneic hematopoietic stem cell transplantation for the treatment of BCR-ABL1-negative atypical chronic myeloid leukemia and chronic neutrophil leukemia: A retrospective nationwide study in Japan.

Atypical chronic myeloid leukemia (aCML) and chronic neutrophilic leukemia (CNL) are rare BCR-ABL1 fusion gene-negative myeloid neoplasms with a predominance of neutrophils. Since no standard therapeutic strategy currently exists for these diseases, we retrospectively evaluated the outcomes of allogeneic hematopoietic stem cell transplantation (allo-HSCT) for aCML and CNL. Data from 14 aCML and 5 CNL patients as their diagnoses were collected using a nationwide survey. Allo-HSCT was performed between 2003 a...

Allogeneic Hematopoietic Cell Transplantation Is an Effective Treatment for Blastic Plasmacytoid Dendritic Cell Neoplasm in First Complete Remission: Systematic Review and Meta-analysis.

It is common practice to refer patients to transplantation centers for allogeneic hematopoietic cell transplantation (allo-HCT) for blastic plasmacytoid dendritic-cell neoplasm (BPDCN) despite lack of randomized controlled trials. We performed a systematic review to assess the totality of evidence pertaining to the efficacy of allo-HCT in BPDCN.
