Researchers have developed a hybrid treatment that harnesses a monoclonal antibody to deliver antisense DNA to acute lymphoblastic leukemia (ALL) cells and that may lead to less toxic treatments for the disease.

DiscussionWe conclude that CB-CIKs, combined with bispecific T-cell–engaging antibodies, offer a novel, effective treatment strategy for leukemia.

Rearrangements involving the neurotrophic receptor kinase genes (NTRK1, NTRK2, and NTRK3; hereafter referred to as TRK) produce oncogenic fusions in a wide variety of cancers in adults and children. Although TRK fusions occur in fewer than 1% of all solid tumors, inhibition of TRK results in profound therapeutic responses, resulting in Breakthrough Therapy FDA approval of the TRK inhibitor larotrectinib for adult and pediatric patients with solid tumors, regardless of histology. In contrast to solid tumors, the frequency of TRK fusions and the clinical effects of targeting TRK in hematologic malignancies are unknown. Here,…

Early T cell precursor acute lymphoblastic leukemia (ETP-ALL) is a new pathological entity with poor outcomes in T cell ALL (T-ALL) that is characterized by a high incidence of loss-of-function mutations in polycomb repressive complex 2 (PRC2) genes. We generated a mouse model of ETP-ALL by deleting Ezh2, one of the PRC2 genes, in p53-null hematopoietic cells. The loss of Ezh2 in p53-null hematopoietic cells impeded the differentiation of ETPs and eventually induced ETP-ALL–like disease in mice, indicating that PRC2 functions as a bona fide tumor suppressor in ETPs. A large portion of PRC2 target genes acquired DNA h…

(University of Texas M. D. Anderson Cancer Center) Almost one year after the US Food and Drug Administration (FDA) approval of chimeric antigen receptor (CAR) T-cell therapy for children with acute lymphoblastic leukemia (ALL), researchers at The University of Texas MD Anderson Cancer Center and the Pediatric Acute Lung Injury and Sepsis Investigators Network (PALISI) today published treatment guidelines for managing the treatment in the online issue of Nature Reviews Clinical Oncology.

B-cell acute lymphoblastic leukemia (ALL) manifests itself as an accumulation of poorly differentiated malignant lymphoid cells within the bone marrow (BM), resulting in the disruption of normal hematopoiesis [1]. BM is also the most common site of disease relapse, contributed by minimal residual disease (MRD), a major factor associated with poor prognosis and mortality [2]. Unlike T-cell lymphoblastic leukemia, MRD in ALL has been less completely studied and its etiology still remains to be more clearly delineated [3].

Publication date: August 2018Source: Seminars in Cancer Biology, Volume 51Author(s): Jessica Nordlund, Ann-Christine SyvänenAbstractAcute lymphoblastic leukemia (ALL) is the most common malignancy in children. ALL arises from the malignant transformation of progenitor B- and T-cells in the bone marrow into leukemic cells, but the mechanisms underlying this transformation are not well understood. Recent technical advances and decreasing costs of methods for high-throughput DNA sequencing and SNP genotyping have stimulated systematic studies of the epigenetic changes in leukemic cells from pediatric ALL patients. The re…

AbstractPurpose of ReviewTreatment options for patients with acute lymphoblastic leukemia (ALL) beyond standard chemotherapy have grown significantly in recent years. In this review, we highlight new targeted therapies in ALL, with an emphasis on immunotherapy.Recent FindingsMajor advances include antibody-based therapies, such as naked monoclonal antibodies, antibody-drug conjugates and bispecific T cell engaging (BiTE) antibodies, as well as adoptive cellular therapies such as chimeric antigen receptor (CAR) T cells. Apart from the above immunotherapeutic approaches, other targeted therapies are being employed in Philade…

On March 29, 2018, blinatumomab (Blincyto, Amgen) received an accelerated expanded approval for the treatment of adult and pediatric patients with B-cell precursor acute lymphoblastic leukemia (ALL) who are in first or second complete remission (CR) and have minimal residual disease (MRD). Blinatumomab was first approved for use in adult patients (in December 2014) and later in pediatric patients (in September 2016) with relapsed or refractory Philadelphia chromosome (Ph)-negative B-cell precursor ALL; the approval was expanded in July 2017 to include patients with Ph-positive disease….

Conclusion: Silymarin decreased early Doxorubicin induced left ventricular systolic function disturbances and can be recommended as adjuvant drug in patients with ALL under doxorubicin therapy.
RECOMMENDATION: Multicenter studies on large number of patients with longer duration of follow up to prove the protective effects of silymarin in early and late Doxorubicin induced cardiotoxicity.
