September 1, 2017 — The U.S. Food and Drug Administration today approved Mylotarg (gemtuzumab ozogamicin) for the treatment of adults with newly diagnosed acute myeloid leukemia whose tumors express the CD33 antigen (CD33-positive AML). The FDA…

BurnettAbstractOlder patients with acute myeloid leukemia represent at least one half of those with the disease for whom randomized clinical trials of new treatments are in development. These patients represent an appropriate population in which to evaluate new treatments against the current standards of care, which could be azacitidine, decitabine, or low-dose cytarabine. However, despite the identification of treatments that can deliver a worthwhile increase in remission, none has yet delivered a survival super…

Roche today announced submission of a supplemental New Drug Application (sNDA) to the United States (U.S.) Food and Drug Administration (FDA) for Venclexta  (venetoclax), in combination with a hypomethylating agent or in combination with low dose cytarabine (LDAC), for treatment of people with previously untreated acute myeloid leukaemia (AML) who are ineligible for intensive chemotherapy.

Mutations in receptor tyrosine kinase/RAS signaling pathway genes are frequent in core-binding factor (CBF) acute myeloid leukemias (AMLs), but their prognostic relevance is debated. A subset of CBF AML patients harbors several signaling gene mutations. Genotyping of colonies and of relapse samples indicates that these arise in independent clones, thus defining a process of clonal interference (or parallel evolution). Clonal interference is pervasive in cancers, but the mechanisms underlying this process remain unclear, and its prognostic impact remains unknown. We analyzed a cohort of 445 adult and pediatric patients with…

Abstract
At present, acute promyelocytic leukemia (APL) is the most curable form of acute myeloid leukemia and can be treated using all-trans retinoic acid and arsenic trioxide. However, the current treatment of APL is associated with some issues such as drug toxicity, resistance and relapse. Therefore, other strategies are necessary for APL treatment. In the present study, we investigated the effects of salinomycin (SAL) on APL cell lines NB4 and HL-60 and determined its possible mechanisms. We observed that SAL inhibite…

Conclusion: Together with changes in the expression/function of receptors targeted by TKIs, the expression of plasma membrane transporters involved in sorafenib uptake/efflux may affect the response of leukemia cells to this drug.

Application of next-generation sequencing (NGS) panels is usually limited to diagnosis, prognosis, and development of personalized treatment strategies/targeted therapies for patients with myeloid malignancies e.g., Myelodysplastic syndrome (MDS), myeloproliferative neoplasms (MPN), and acute myelogenous leukemia (AML). Here we present a case of 3 year old male that presented with pancytopenia and splenomegaly. His initial bone marrow revealed mild to moderate fibrosis (normocellular; no increase in blasts).

Acute myeloid leukemia (AML) is grouped in multiple subtypes based on recurrent genomic abnormalities with diagnostic and prognostic significance. To enhance our diagnostic approach, we developed a clinical whole-genome mate pair-sequencing (MPseq) assay to detect structural rearrangements and copy number changes. DNA is processed using Illumina Nextera MP library kit, sequenced and aligned to the reference genome using BIMA. Abnormalities are visualized using Mayo-developed Ingenium software using AML-panel restricting analysis to classic-AML rearrangements: ABL1, BCR, CBFB, CREBBP, DEK, KAT6A, MECOM, MLF1, MLL(KMT2A), MY…
