NCCN Guidelines Updates: Discontinuing TKI Therapy in the Treatment of Chronic Myeloid Leukemia.

The NCCN Guidelines for Chronic Myeloid Leukemia (CML) criteria for discontinuation of tyrosine kinase inhibitor (TKI) therapy have not seen significant updates in the past year, but the current guidelines reinforce the safety of treatment discontinuation in appropriate and consenting patients with CML in the chronic phase who have achieved and maintained a deep molecular response. According to Dr...

Chromosomal microarray analysis is superior in identifying cryptic aberrations in patients with acute lymphoblastic leukemia at diagnosis/relapse as a single assay.

Conventional cytogenetics (CC) is important in diagnosis, therapy, monitoring of post-transplant bone marrow, and prognosis assessment of acute lymphoblastic leukemia (ALL). However, due to the nature of ALL, CC often encounters difficulties of complex karyotype, poor chromosome morphology, low mitotic index, or normal cells dividing only. In contrast, chromosomal microarray analysis (CMA) showed ...

Incorporating Precision BH3 Warheads Into the Offensive Against Acute Myeloid Leukemia.

Pivotal role of mitophagy in response of acute myelogenous leukemia to a ceramide-tamoxifen-containing drug regimen.

Acute myelogenous leukemia (AML) is a hematological malignancy marked by the accumulation of large numbers of immature myeloblasts in bone marrow. The overall prognosis in AML is poor; hence, there is a pressing need to improve treatment. Although the sphingolipid (SL) ceramide demonstrates known cancer suppressor properties, it's mechanism of action is multifaceted. Our studies in leukemia and ot...

Proteomic Profiling of Signaling Networks Modulated by G-CSF/Plerixafor/Busulfan-Fludarabine Conditioning in Acute Myeloid Leukemia Patients in Remission or with Active Disease prior to Allogeneic Stem Cell Transplantation.

To characterize intracellular signaling in peripheral blood (PB) cells of acute myeloid leukemia (AML) patients undergoing pretransplant conditioning with CXCR4 inhibitor plerixafor, granulocyte colony-stimulating factor (G-CSF), and busulfan plus fludarabine (Bu+Flu) chemotherapy, we profiled 153 proteins in 33 functional groups using reverse phase protein array. CXCR4 inhibition mobilized AML pr...

Can Chronic-Phase Chronic Myeloid Leukemia Patients Achieve Optimal and Durable Responses after Two Failed TKI Treatments? Real-World Evidence Data.

Atypical Chronic Myeloid Leukemia in a Patient with Aplastic Anemia.

Leukemia inhibitory factor promotes the regeneration of rat uterine horns with full thickness injury.

Severe uterine injuries may lead to infertility or pregnancy complications. There is a lack of effective methods to restore the structure and function of seriously injured uteri. Leukemia inhibitory factor (LIF), which plays a crucial role in blastocyst implantation, promotes the process of regeneration after injury in several different tissues. In this study, we explored the effect of LIF on the ...

Symptom Clusters and Influencing Factors in Children With Acute Leukemia During Chemotherapy.

Acute leukemia is the most common malignancy in childhood. Identification of symptom clusters and their influencing factors in children with acute leukemia may improve the management of symptoms.

Risk and outcomes of second malignant neoplasms in chronic myeloid leukemia survivors.

The risk of second malignant neoplasms (SMN) in chronic myeloid leukemia (CML) survivors remains unclear. We utilized the Surveillance, Epidemiology and End Results 18 (SEER 18) registries to evaluate the risk and subsequent outcomes of SMN in CML survivors. There were 3407 patients included. Of these, 170 (4.99%) developed a SMN with SIR of 1.40 (95% C.I. 1.19-1.62). An increased risk was noted f...

Long-Term Outcomes of Modified St Jude Children's Research Hospital Total Therapy XIIIB and XV Protocols for Thai Children With Acute Lymphoblastic Leukemia.

We studied long-term outcomes and prognostic features of Thai children with acute lymphoblastic leukemia treated with modified St Jude Children's Research Hospital (SJCRH) protocols.

Predictors of mortality among patients with acute leukemias admitted to an intensive care unit specialized in patients with hematological disease at a Brazilian hospital.

Hematologists deal every day with high mortality rates of acute leukemia patients. Many times these patients need Intensive Care Unit (ICU) support and some general ICU teams believe that these patients have a much greater chance of dying than patients with other pathologies. In Brazil, data related to mortality rates and ICUs for acute leukemia patients are scarce.

Socioeconomic status and incidence of pediatric leukemia in Canada: 1992-2010.

Leukemia is the most common cancer among Canadian children, representing about a third of pediatric cancers in Canada and is responsible for about one-third of pediatric cancer deaths. Understanding the effect of socioeconomic status (SES) on pediatric leukemia incidence provides valuable information for cancer control and interventions in Canada.

Lipid nanoparticle-mediated siRNA delivery for safe targeting of human CML in vivo.

Efficient and safe delivery of siRNA in vivo is the biggest roadblock to clinical translation of RNA interference (RNAi)-based therapeutics. To date, lipid nanoparticles (LNPs) have shown efficient delivery of siRNA to the liver; however, delivery to other organs, especially hematopoietic tissues still remains a challenge. We developed DLin-MC3-DMA lipid-based LNP-siRNA formulations for systemic d...

Expression of gene and its prognostic value in patients with acute myeloid leukemia.

To investigate the expression of Wilms'tumor 1 () gene in patients with acute myeloid leukemia (AML), and to explore its application in predicting prognosis of AML in patients with wild or mutated nucleophosmin 1() and Fms-like tyrosine kinase 3-internal tandem duplication ().

Decitabine treatment for an unusual case of atypical chronic myeloid leukemia (aCML) with a concomitant chronic lymphocytic leukemia (CLL).

Atypical chronic myeloid leukemia (aCML) is a rare hematological malignancy with dismal prognosis, usually being reported as isolated disease or in association with other myeloid neoplasms. Treatment strategies used for MDS and MPN, as hypomethylating agents (HMA) or kinase inhibitors, may be considered although experience is limited. We biologically studied an old patient affected by aCML unusual...

Predisposing germline mutations in high hyperdiploid acute lymphoblastic leukemia in children.

High hyperdiploidy (HD) is the most common cytogenetic subtype of childhood acute lymphoblastic leukemia (ALL), and a higher incidence of HD has been reported in ALL patients with congenital cancer syndromes. We assessed the frequency of predisposing germline mutations in 57 HD-ALL patients from the California Childhood Leukemia Study (CCLS) via targeted sequencing of cancer-relevant genes. Three ...

Current outlook on drug resistance in chronic myeloid leukemia (CML) and potential therapeutic options.

Chronic myeloid leukemia (CML) is a myeloproliferative neoplasm the hallmark of which, the breakpoint cluster region-Abelson (BCR-ABL) oncogene, has been the target of tyrosine kinase inhibitors (TKIs), which have significantly improved the survival of patients with CML. However, because of an increase in TKI resistance, it is becoming imperative to identify resistance mechanisms so that drug ther...

Moxetumomab Pasudotox: Clinical Experience in Relapsed/Refractory Hairy Cell Leukemia.

Moxetumomab pasudotox is a promising new therapy for the treatment of patients with relapsed/refractory hairy cell leukemia (R/R HCL), but practical guidance relating to its administration is limited.

A case of extramedullary hematopoiesis presenting as hemorrhagic panniculitis and evolving in acute myeloid leukemia.

Extramedullary hematopoiesis (EMH) in adults is a rare event, usually associated with myeloid disorders, and can be the first sign of chronic myelomonocytic leukaemia. We report a case of EMH presenting as a hemorrhagic panniculitis in a patient who did not apparently present any myeloid disorders. The patient received previous chemotherapy for mantle cell lymphoma localized to the large bowel and...

Allogeneic hematopoietic stem cell transplantation from unrelated donors is associated with higher infection rates in children with acute lymphoblastic leukemia - A prospective international multicenter trial on behalf of the BFM-SG and the EBMT-PDWP.

Severe infections (SI) significantly impact on non-relapse mortality after hematopoietic stem cell transplantation (HSCT). We assessed 432 children and adolescents with acute lymphoblastic leukemia (ALL) after total body irradiation based myeloablative HSCT within the multicenter ALL-BFM-SCT 2003 trial for SI grade 3 or higher according to common terminology criteria for adverse events. A total 17...

Analysis of apoptotic, platelet-derived, endothelial-derived, and tissue factor-positive microparticles of children with acute lymphoblastic leukemia during induction therapy.

Thromboembolism is one of the most common complications during induction therapy of pediatric acute lymphoblastic leukemia (ALL). Procoagulant microparticles in the circulation may cause thromboembolic events. The aim of our study was to determine the levels of apoptotic, platelet-derived, endothelial-derived, and tissue factor-positive microparticles of children with ALL at diagnosis and during i...

Role of Interferon (IFN)α in "Cocktails" for the Generation of (Leukemia-derived) Dendritic Cells (DCleu) From Blasts in Blood From Patients (pts) With Acute Myeloid Leukemia (AML) and the Induction of Antileukemic Reactions.

Strategies to stabilize remissions by specific elimination of residual acute myeloid leukemia (AML) blasts are needed. Leukemia-derived dendritic cell (DCleu/DC) generated from myeloid blasts improve antileukemic T-cell reactivity and install T-cell memory. Interferon (IFN)α-DC methods produce DCleu from chronic myeloid leukemia-patients (pts') blood. Various INFα-containing versus other DC meth...
