Systematic review of azacitidine regimens in myelodysplastic syndrome and acute myeloid leukemia

ConclusionsIndirect comparison of alternative azacitidine dosing regimens in MDS and AML shows a benefit for the 7-day regimen in attaining ORR. Additional RCTs are required to definitively address this comparison.

However, these agents must be administered intravenously or subcutaneously because they are degraded easily by cytidine deaminase (CDA). OR2100 (OR21), an...

Purpose of review By establishing mechanisms that deliver oxygen to sustain cells and tissues, fight life-threatening pathogens and harness the immune system to eradicate cancer cells, hematopoietic stem and progenitor cells (HSPCs) are vital in health and disease. The cell biological framework for HSPC generation has been rigorously developed, yet recent single-cell transcriptomic analyses have unveiled permutations of the hematopoietic hierarchy that differ considerably from the traditional roadmap. Deploying mutants that disrupt specific steps in hematopoiesis constitutes a powerful strategy for deconvoluting the comp...

CONCLUSION: This study showed the frequency and pattern of chromosomal abnormalities of MDS patients in upper northern Thailand were different from other populations. MDS with isolated chromosome 5 abnormalities had clinical characteristics corresponding with patients in good prognosis risk group. However, MDS patients with chromosome 7 and complex abnormalities showed higher percentage blast of BM which high risk to progression to acute myeloid leukemia (AML). Combined CC and FISH techniques detect chromosomal abnormalities with greater frequency than when either technique is used alone.. PMID: 32212788 [PubMed - in process]

ConclusionsWe conclude that oral AZA when combined with CDZ achieves successful tumor regression in both CDX and PDX models. Furthermore, the combination of AZA  + CDZ with VEN in a PDX model emulated responses seen with VEN + AZA in the clinic, implying a potential all-oral VEN-based therapy opportunity in myeloid diseases.

TheASXL1 mutation frequency is high in AML ‐MRC patients being its presence associated with specific characteristics, including morphological signs of dysplasia. This association raises the possible role ofASXL1 as a surrogate marker in AML ‐MRC, which could facilitate the diagnosis of patients within this group when the karyotype is normal, and especially when the assessment of multilineage dysplasia morphologically is difficult. This mutation could be used as a worst outcome marker in de novo AML‐MRC with intermediate‐risk kar yotype. AbstractAcute myeloid leukemia with myelodysplasia ‐related changes (AML...

The distinction between myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML) often relies on an arbitrary marrow blast cutoff of 30% in pediatrics and 20% in adults. There is little data about the treatment of children with extramedullary myeloid malignancy that has features of both, MDS and AML. Herein, we report for the first time 2 patients MDS/AML (1 with Shwachman-Diamond syndrome and 1 with idiopathic MDS and monosomy 7) who presented with extramedullary complications, received treatment with azacitidine, achieved complete remission and subsequently underwent hematopoietic stem cell transplantation.

Conclusion: The findings support ICT in iron-overloaded patients with low- to intermediate-1-risk MDS, with longer EFS compared with placebo and a clinically manageable safety profile. Therefore, ICT may be considered in these patients. Primary Funding Source: Novartis Pharma AG. PMID: 32203980 [PubMed - as supplied by publisher]

Cells become senescent in response to a variety of circumstances. The vast majority are cases of replicative senescence, somatic cells reaching the Hayflick limit. Cell damage and toxic environments also produce senescence, and senescent cells are also created as a part of the wound healing process. A senescent cell ceases replication and begins to secrete inflammatory and pro-growth signals, altering the nearby extracellular matrix and behavior of surrounding cells - even encouraging them to become senescent as well. Near all senescent cells last a short time only, as they self-destruct or are removed by the immune...
