Improving risk-stratification of patients with chronic lymphocytic leukemia using multivariate patient similarity networks.

Better risk-stratification of patients with chronic lymphocytic leukemia (CLL) and identification of subsets of ultra-high-risk (HR)-CLL patients are crucial in the contemporary era of an expanded therapeutic armamentarium for CLL.

Low ferroportin expression in AML is correlated with good risk cytogenetics, improved outcomes and increased sensitivity to chemotherapy.

Iron metabolism is altered in a variety of cancers; however, little is known about the role of iron metabolism in the biology and response to therapy of acute myeloid leukemia (AML). Here we show that SLC40A1, the gene encoding the iron exporter ferroportin (FPN), is variably expressed among primary AMLs and that low levels are associated with good prognosis and improved outcomes. In particular, core binding factor (CBF) AMLs, which are associated with good outcomes with chemotherapy, consistently have low ...

Programmed Cell Death Receptor (PD-1) Ligand (PD-L1) expression in Philadelphia chromosome-negative myeloproliferative neoplasms.

Programmed Cell Death Receptor (PD-1) and its Ligand (PD-L1) pathway inhibitor therapy has been explored in the field of oncology treatment mainly for solid tumors. In hematologic malignancies, there is limited information except for Hodgkin's lymphoma, and there is even less information regarding myeloproliferative neoplasm (MPN). Therefore, we explored this by first measuring PD-1 and PD-L1 levels (percentage of positive cells) in 63 patients with Philadelphia chromosome-negative MPN (Ph(-) MPN), includin...

Phase 1/2 trial of glasdegib in patients with primary or secondary myelofibrosis previously treated with ruxolitinib.

Glasdegib is a potent and selective oral inhibitor of the Hedgehog pathway. We report data from the single-arm, lead-in cohort of an open-label phase 1b/2 trial of glasdegib in patients with primary/secondary myelofibrosis (MF) previously treated with at least one Janus kinase inhibitor (JAKi). Patients received glasdegib 100 mg orally once daily until there was no further clinical benefit. Primary endpoints included adverse events (AEs). Secondary endpoints included patients with spleen volume reduction ...

Ex vivo resistance in childhood acute lymphoblastic leukemia: Correlations between BCRP, MRP1, MRP4 and MRP5 ABC transporter expression and intracellular methotrexate polyglutamate accumulation.

Chemoresistance is an important factor in the treatment failure of childhood acute lymphoblastic leukemia (ALL). One underlying mechanism of chemoresistance involves (over)expression of ATP-dependent drug efflux transporters such as multidrug resistance protein 1-5 (MRP1-5) and breast cancer resistance protein (BCRP), which can extrude the important antileukemia drug methotrexate (MTX). Survival of childhood ALL critically depends on the leukemic blasts' capacity for intracellular retention of MTX and MTX-p...

Replicative senescence of hematopoietic cells in patients with idiopathic cytopenia of undetermined significance.

We hypothesized that a subset of idiopathic cytopenia of undetermined significance (ICUS) is associated with an increased autonomous proliferation with exhaustion of hematopoiesis. The aim of this study was to investigate the cell turnover rate and replicative history of the bone marrow cells of ICUS patients. To this end, we examined telomere length (TL), proliferation, and apoptosis of the bone marrow cells of ICUS patients and healthy controls (HCs) using telomere quantitative fluorescence in situ hybrid...

Blinatumomab administered concurrently with oral tyrosine kinase inhibitor therapy is a well-tolerated consolidation strategy and eradicates measurable residual disease in adults with Philadelphia chromosome positive acute lymphoblastic leukemia.

Incorporation of ABL-targeted oral tyrosine kinase inhibitors (TKIs) into frontline therapeutic regimens has improved outcomes for adults with Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph + ALL). However, patients with persistent minimal residual disease (MRD) exhibit increased risk of relapse. Combining consolidative chemotherapy with TKIs may increase rates of infectious complications, organ toxicity, hospitalization, and non-relapse mortality. Blinatumomab has demonstrated single...

The value of FDP/FIB and D-dimer/FIB ratios in predicting high-risk APL-related thrombosis.

Hemorrhage is the typical manifestation of APL-related coagulopathy while thrombosis is infrequently reported. In a retrospective analysis with 33 patients with hyperleukocytic APL, we found 6 out of 33 hyperleukocytic APL patients presented with thrombosis rather than hemorrhage. A notable feature in these high-risk APL patients with thrombosis is that there were no significant abnormalities in fibrinogen (FIB), prothrombin time (PT) and activated partial thromboplastin time (APTT). Compared with the norma...

Prospective observational study in comorbid patients with chronic lymphocytic leukemia receiving first-line bendamustine with rituximab.

Chemoimmunotherapy with bendamustine and rituximab is an alternative treatment for elderly patients with CLL. The aim of this observational multicenter study was to prospectively assess efficacy and safety of bendamustine and rituximab in front-line therapy in patients with CLL and significant comorbidities in real hematological practice. Eighty-three consecutive patients with cumulative illness rating scale (CIRS) >6 who received at least one cycle of BR as first-line treatment were included in the study. ...

Chronic myeloid leukemia: Two mysteries.

The spectrum of musculoskeletal symptoms in patients with chronic myeloid leukemia after stopping tyrosine kinase inhibitors.

A retrospective study evaluating treatment patterns and survival outcomes in elderly patients with acute myeloid leukemia treated in the United States with either 7+3 or a hypomethylating agent.

Intensive treatment for newly diagnosed acute myelogenous leukemia (ND-AML) patients are reserved for "fit" patients. While guidelines recommend evaluation of age, performance status and comorbidities, there is no consensus on the definition of "fitness" or optimal therapy for elderly AML patients. This retrospective study evaluated characteristics and survival outcomes of 274 patients (age ≥60 years) with ND-AML treated with 7 + 3 (cytarabine + an anthracycline) vs. hypomethylating agents (HMAs)....

Should patient age be an obstacle for high-dose therapy and stem cell rescue?

A kinase profile-adapted drug combination elicits synergistic cooperative effects on leukemic cells carrying BCR-ABL1 in Ph+ CML.

In chronic myeloid leukemia (CML), resistance against second-generation tyrosine kinase inhibitors (TKI) remains a serious clinical challenge, especially in the context of multi-resistant BCR-ABL1 mutants, such as T315I. Treatment with ponatinib may suppress most of these mutants, including T315I, but is also associated with a high risk of clinically relevant side effects. We screened for alternative treatment options employing available tyrosine kinase inhibitors (TKI) in combination. Dasatinib and bosutin...

The relationship between clinical trial accrual volume and outcomes in acute myeloid leukemia: A SWOG/ECOG-ACRIN study (S0106 and E1900).

To study whether institutional clinical trial accrual volume affects clinical outcomes of younger (age less than 61 years) patients with acute myeloid leukemia.

STAT5b-RARa-positive acute myeloid leukemia: Diagnostic and therapeutic challenges of a rare AML subtype.

A registry-based analysis of survival outcomes in mast cell leukemia.

Mast cell leukemia (MCL) is rare and carries a poor prognosis. No standard-of-care has been established. No USA registry-based analyses have examined clinical correlates of overall survival (OS) in MCL patients, thus we aimed to do this using the Surveillance, Epidemiology, and End Results (SEER) database, and the National Cancer Database (NCDB).

Evidence for activated Lck protein tyrosine kinase as the driver of proliferation in acute myeloid leukemia cell, CTV-1.

Acute myeloid leukemia (AML) is a heterogeneous group of fast growing cancers of myeloid progenitor cells, for which effective treatments are still lacking. Identification of signaling inhibitors that block their proliferation could reveal the proliferative mechanism of a given leukemia cell, and provide small molecule drugs for targeted therapy for AML. In this study, kinase inhibitors that block the majority of cancer signaling pathways are evaluated for their inhibition of two AML cell lines of the M5 su...

Computational modeling of early T-cell precursor acute lymphoblastic leukemia (ETP-ALL) to identify personalized therapy using genomics.

Early T-cell precursor acute lymphoblastic leukemia (ETP-ALL) is an aggressive hematological malignancy for which optimal therapeutic approaches are poorly characterized. Using computational biology modeling (CBM) in conjunction with genomic data from cell lines and individual patients, we generated disease-specific protein network maps that were used to identify unique characteristics associated with the mutational profiles of ETP-ALL compared to non-ETP-ALL (T-ALL) cases and simulated cellular responses t...

Involvement of pRb-E2F pathway in green tea extract-induced growth inhibition of human myeloid leukemia cells.

Both inhibitory and stimulatory effect of EGCG on cancer cells have been reported, which often is linked to receptor tyrosine kinase signaling. In this study, we present evidence that green tea extract and its chemical component, Epigallocatechin-3-gallate (EGCG), inhibit growth of human myeloid leukemia cells through the regulation of pRb synthesis and formation of pRb-E2F complexes. Addition of green tea extract to the culture of TF-1a and MV4-11 myeloid leukemia cells significantly inhibited their prolif...

A novel entity of acute myeloid leukaemia with recurrent RARG-rearrangement resembling acute promyelocytic leukaemia.

Tropolone-induced effects on the unfolded protein response pathway and apoptosis in multiple myeloma cells are dependent on iron.

Tropolones are naturally occurring seven-membered non-benzenoid aromatic compounds that are of interest due to their cytotoxic properties. MO-OH-Nap is a novel α-substituted tropolone that induces caspase cleavage and upregulates markers associated with the unfolded protein response (UPR) in multiple myeloma (MM) cells. Given previous reports that tropolones may function as iron chelators, we investigated the effects of MO-OH-Nap, as well as the known iron chelator deferoxamine (DFO), in MM cells in the pr...

Molecular response to imatinib in KIT F522C-mutated systemic mastocytosis.

Additional prognostic impact of the percentage of erythroid cells in the bone marrow of patients with myelodysplastic syndromes.

In patients with myelodysplastic syndromes (MDS) the impact of the percentage of erythroid precursors in the bone marrow has been the subject of considerable debate, especially with regard to prognosis. We examined the prognostic impact of the percentage of erythroid cells in the bone marrow (bmery) in 2453 primary untreated MDS patients in a retrospective multi-center analysis. Bmery were quantified in bone marrow smears at the time of diagnosis and were correlated with overall survival (OS) and AML evolut...
