AbstractAzacitidine and decitabine, two hypomethylating agents, are known to be effective in the treatment of high-risk myelodysplastic syndromes (MDS) and acute myeloid leukemia (AML) patients who cannot endure intensive cytotoxic chemotherapy or are not eligible for transplantation. However, the treatment response rate is low. The molecular mechanisms underlying the resistance to demethylation therapy are unclear. Though a wide range of predictors of treatment response have been investigated, no consensus has been reached. It is imperative to identify certain parameters that can help distinguish between patients who will…

In conclusion, inhibition of ODC1 by DFMO was crucial in facilitating BCT‑100 treatment in lung adenocarcinoma that was partially mediated by depleting arginine and polyamines with consequent apoptosis.

Abstract
Acute myeloid leukemia (AML) is widely considered a distinct clinical entity with a well-defined molecular and genetics-based prognosis. Particularly in a younger patient, the therapeutic approach depends largely on diagnostic risk stratification, which has an impact on the outcome after therapy. We added Treg evaluation to the usual molecular and cytogenetics profile in the AML younger patients’ diagnostic bone marrow aspirate (dBMA) in order to search for any correlation between Tregs and overall response (OR) as well as survival …

Jones, Kirsten GrønbækAbstractOver the past few years it has become clear that vitamin C, as a provider of reduced iron, is an essential factor for the function of epigenetic regulators that initiate the demethylation of DNA and histones. Vitamin C deficiency is rare in the general population, but is frequently observed in patients with cancer. Genes encoding epigenetic regulators are often mutated in cancer, underscoring their central r…

We used an extracellular flux analyze to examine metabolic changes during leukemia development in a mouse model of MLL-r AML expressing high levels of Evi1 (Evi1+).

We describe the first multicenter prospective study to assess the efficacy, safety, and immune reconstitution of a novel sequential transplant approach in 24 patients with primary induction failure/relapsed acute myeloid leukemia (AML). The sequential regimen consisted of cladribine 5  mg/m2/day and cytarabine 2  g/m2/day for 5  days and mitoxantrone 7 mg/m2/day for 3  days, followed by myeloablative allogeneic hematopoietic stem cell transplantation (allo-HSCT) using intravenous busulfan (3.2 mg/kg/day) for 4 days and cyclophosphamide (60 mg/kg/day) for 2 days. Patients in CR w…

AbstractIntensive chemotherapy (IC) used to be a common treatment approach for patients with higher-risk myelodysplastic syndromes (MDS) or acute myeloid leukemia after MDS (sAML). We conducted a retrospective analysis of 299 patients, including a matched pair analysis comparing 96 patients receiving IC with 96 patients not undergoing IC, in order to evaluate the impact of IC on overall survival (OS) and to identify factors that influence remission rates and OS. Complete remission (CR) after first induction chemotherapy was reached in 50% of patients. Parameters influencing the probability of achieving CR were blast count in the bone marrow (
