Chronic myelomonocytic leukemia (CMML) is an uncommon neoplastic hematological disorder, typically affecting the elderly, and characterized by a marked clinical heterogeneity and a remarkable propensity for transformation into acute myeloid leukemia. Hypomethylating agents represent the most innovative management approach in this difficult setting. At our institution, between 2010 and 2012, we have treated with azacitidine 10 CMML patients with a median age of 75 (62-86) years. The overall response rate of 70% was achieved without remarkable toxicities; in particular, most therapy-induced side effects were managed on outpatient basis. With a median follow-up of 12,5 (2-27) months, 6 patients are alive, and 4 of them continue to receive the treatment; the median survival from the start of therapy was not reached. In conclusion, also in the light of our encouraging experience, azacitidine can offer new chances of treatment also in the difficult setting of elderly CMML.

partial tandem duplication (PTD) involves intragenic duplications and has been associated with poorer prognosis. In this study, we evaluated PTD in 1277 patients with hematological malignancies using optical genome mapping (OGM). PTD was detected in 35 patients with acute myeloid leukemia (AML) (7%), 5 patients with myelodysplastic syndrome (MDS) (2.

An 8 yr old, male, mixed-breed dog was presented with a 2 mo history of progressive weakness, worsened in the last 2 days before examination. Neurological examination revealed ambulatory tetraparesis, ataxia, and proprioceptive deficits in all four limbs. Menace response was reduced in the right eye and discomfort was detected on neck manipulation.

is one of the three most frequently mutated genes in age-related clonal hematopoiesis (CH), alongside and (. CH can progress to myeloid malignancies including chronic monomyelocytic leukemia (CMML) and is also strongly associated with inflammatory cardiovascular disease and all-cause mortality in humans. DNMT3A and TET2 regulate DNA methylation and demethylation pathways, respectively, and loss-of-function mutations in these genes reduce DNA methylation in heterochromatin, allowing derepression of silenced elements in heterochromatin.

Chronic myelomonocytic leukemia (CMML) is a myelodysplastic/myeloproliferative neoplasm characterized by peripheral blood monocytosis and bone marrow dysplasia. In approximately one-fourth of cases, CMML can demonstrate progression to acute myeloid leukemia (AML), referred to as AML ex CMML. We present a 58-year-old woman with a past medical history of idiopathic thrombocytopenic purpura (ITP) who demonstrated 24% bone marrow blasts on a repeat biopsy obtained two years after being diagnosed with CMML.
