Pleural effusion may occur as a rare complication associated with myeloid hematological malignancies. However, it occasionally occurs in patients with myelodysplastic/myeloproliferative neoplasms(MDS/MPN), especially in chronic myelomonocytic leukemia(CMML)with marked leukocytosis. Pleural effusion can also develop in hematological disorders with bone marrow fibrosis. Here, we report a case of CMML with bone marrow fibrosis, in which massive pleural effusion developed rapidly during cytoreductive therapy with hydroxycarbamide(HU)...

DNMT3A mutations are seen in ∼5% of patients with chronic myelomonocytic leukemia (CMML) and thus far, have had an indeterminate prognostic impact on survival. We carried out this study to assess the prognostic impact of DNMT3A mutations on a larger informative cohort of CMML patients (n=261). DNMT3A mutations were seen in 6% (n=16); 56% (n=9) male, with a median age of 64 years. Eighty-one % of DNMT3A mutations were missense, with the Arg882 mutational hot spot accounting for 63% of all changes. Five (31%) patients had an abnormal karyotype whereas concurrent gene mutations (SF3B1/SRSF2/U2AF1-56%, TET2-50%, and ASXL1-25%) were seen in all patients...

Exome sequencing studies in Chronic Myelomonocytic Leukemia (CMML) illustrate a mutational landscape characterized by few somatic mutations involving a subset of recurrent gene mutations in ASXL1, SRSF2, and TET2, each approaching 40% in incidence. This has led to the clinical implementation of next generation sequencing panels that effectively identify clonal monocytosis and complement clinical prognostic scoring systems in most patients. However, most murine models based on single gene mutations fail to recapitulate the CMML phenotype and many gene mutations are loss-of-function making the identification of traditional therapeutic vulnerabilities challenging...

MDS/MPN (myelodysplastic syndrome/myeloproliferative neoplasm) overlap syndromes are myeloid malignancies for which allogeneic hematopoietic stem cell transplant (allo-HSCT) is potentially curative. We describe transplant outcomes of 43 patients - 35 with chronic myelomonocytic leukemia, CMML (of which 17 had blast transformation, BT) and eight with MDS/MPN-unclassifiable (MDS/MPN,U). At median follow-up of 21 months, overall survival (OS), cumulative incidence of relapse (CIR) and non-relapse mortality (NRM) were 55%, 29%, and 25% respectively in CMML without BT and 47%, 40%, and 34% respectively in CMML with BT...

According to the recently published 2016 World Health Organization (WHO) classification of myeloid malignancies, myelodysplastic/myeloproliferative neoplasms (MDS/MPN) include atypical chronic myeloid leukemia (aCML), MDS/MPN-unclassifiable (MDS/MPN-U), chronic myelomonocytic leukemia (CMML), juvenile myelomonocytic leukemia (JMML), and MDS/MPN ring sideroblasts with thrombocytosis (MDS/MPN-RS-T). MDS/MPN-RS-T was previously a provisional category known as refractory anemia with ring sideroblasts with thrombocytosis (RARS-T) which has now attained a distinct designation in the 2016 WHO classification...

An 80-year-old man was admitted to our hospital because of severe thrombocytopenia. He was diagnosed with idiopathic thrombocytopenia, and prednisolone together with eltrombopag was started, leading to significant improvement of platelet counts. Four years later, there was a prominent increase of peripheral blood monocytes, which was accompanied by recurrence of thrombocytopenia. Bone marrow aspirates and serum electrophoresis revealed coexistence of chronic myelomonocytic leukemia (CMML) and multiple myeloma (MM)...

Fc gamma receptor I (FcγRI, CD64) is a well-known target antigen for passive immunotherapy against acute myeloid leukemia and chronic myelomonocytic leukemia. We recently reported the preclinical immunotherapeutic potential of microtubule associated protein tau (MAP) against a variety of cancer types including breast carcinoma and Hodgkin's lymphoma. Here we demonstrate that the CD64-directed human cytolytic fusion protein H22(scFv)-MAP kills ex vivo 15-50% of CD64+ leukemic blasts derived from seven myeloid leukemia patients...

PURPOSE: The poly(ADP-ribose) polymerase (PARP) inhibitor veliparib delays DNA repair and potentiates cytotoxicity of multiple classes of chemotherapy drugs, including topoisomerase I inhibitors and platinating agents. This study evaluated veliparib incorporation into leukemia induction therapy using a previously described topotecan/carboplatin backbone. EXPERIMENTAL DESIGN: Employing a 3+3 trial design, we administered escalating doses of veliparib combined with topotecan + carboplatin in relapsed or refractory acute leukemias, aggressive myeloproliferative neoplasms (MPNs) and chronic myelomonocytic leukemia (CMML)...

BACKGROUND (OR PURPOSE): Inflammation has an essential role in the pathogenesis of myelodysplastic syndromes (MDS). Its expression is controlled by phosphodiesterase 4 (PDE4). Thus, PDE4 inhibitors might be useful therapeutic targets for MDS. PATIENTS (OR MATERIALS) AND METHODS: We evaluated the expression of each isoform of PDE4 (A, B, C, and D) using transcriptomic profiling and examined the potential impact on the outcome of patients with MDS in terms of survival and response to hypomethylating agents...

INTRODUCTION: Eltrombopag used for thrombocytopenia in myelodysplastic syndrome (MDS) patients is being explored in clinical trials including those with chronic myelomonocytic leukemia (CMML). PATIENTS AND METHODS: We report our experience treating patients with CMML enrolled in a sequential 2-stage dose escalation study with eltrombopag in patients with MDS after hypomethylating agent failure. Patients with CMML were compared with patients with MDS in respect to response and adverse events...

Clonal cytogenetic abnormalities are found in 20-30% of patients with chronic myelomonocytic leukemia (CMML), while gene mutations are present in >90% of cases. Patients with low risk cytogenetic features account for 80% of CMML cases and often fall into the low risk categories of CMML prognostic scoring systems, but the outcome differs considerably among them. We performed targeted deep sequencing of 83 myeloid-related genes in 56 CMML patients with low risk cytogenetic features or uninformative conventional cytogenetics (CC) at diagnosis, with the aim to identify the genetic characteristics of patients with a more aggressive disease...

In order to clarify the relationship between myelodysplastic morphologic features of marrow cells and prognoses and 1.0 define other prognostic factors, 124 patients with the FAB criteria of myelodysplastic syndrome (MIX) were analysed. These included 57 patients with refractory anemia (RA), 5 RA with ring sideroblasts (RARS), 25 RA with excess of blasts (RAEB), 14 chronic myelomonocytic: leukemia (CMML) and 23 with RAEB in transformation (RAEB in T). Univariate analysis of all MDS patients or those of RA demonstrated that the following factors, which were not reported or fully investigated previously, were significantly associated with prognosis...

Azacitidine (AZA) is a hypomethylating drug used to treat disorders associated with myelodysplasia and related neoplasms. Approximately 50 % of patients do not respond to AZA and have very poor outcomes. There is thus great interest in identifying predictive biomarkers for AZA responsiveness. We searched for specific genes whose expression level was associated with response status. Using microarrays, we analyzed gene expression patterns in bone marrow CD34(+) cells in serial samples from 32 patients with myelodysplastic syndromes, chronic myelomonocytic leukemia, and acute myeloid leukemia with myelodysplasia-related changes before and during the AZA therapy...

OBJECTIVES: We sought to immunophenotype blasts, monocytes, and granulocytes in chronic myelomonocytic leukemias (CMMLs) and compare CMML subtypes, to identify if significant antigen expression differences existed. METHODS: Bone marrow blasts, monocytes, and granulocytes from CMML subgroups (n = 30; World Health Organization types 1/2, proliferative/dysplastic, therapy related/de novo, and low/intermediate/high cytogenetic risk) were immunophenotypically compared by flow cytometry with 10 nonneoplastic control marrows...

ENMD-2076 is a novel, orally-active molecule that inhibits Aurora A kinase, as well as c-Kit, FLT3 and VEGFR2. A phase I study was conducted to determine the maximum tolerated dose (MTD), recommended phase 2 dose (RP2D) and toxicities of ENMD-2076 in patients with acute myeloid leukemia (AML) and chronic myelomonocytic leukemia (CMML). Patients received escalating doses of ENMD-2076 administered orally daily [225 mg (n = 7), 375 mg (n = 6), 325 mg (n = 9), or 275 mg (n = 5)]. Twenty-seven patients were treated (26 AML; 1 CMML-2)...

Chronic myelomonocytic leukemia (CMML) is a myelodysplastic/myeloproliferative neoplasm with variable clinical course. To predict the clinical outcome, we previously developed a CMML-specific prognostic scoring system (CPSS) based on clinical parameters and cytogenetics. In this work, we tested the hypothesis that accounting for gene mutations would further improve risk stratification of CMML patients. We therefore sequenced 38 genes to explore the role of somatic mutations in disease phenotype and clinical outcome...
