(Mary Ann Liebert, Inc./Genetic Engineering News) The neurotoxic effects of chemotherapeutic drugs on the developing brains of young patients with acute lymphoblastic leukemia (ALL) may impair their cognitive functioning by disrupting the formation of neural networks that connect brain regions and transfer information. A study showing reduced connectome organization in the brains of ALL survivors is published in Brain Connectivity.

INTRODUCTION: Acute lymphoblastic leukemia (ALL) is a clonal disease of the hematopoietic system characterized by unique genetic characteristics. The significance of these genetic features has evolved over the past three decades. In the 1980s and 1990s the primary interest was in excluding the Philadelphia chromosome; a finding more common in older adults which uniformly predicted for a rapidly fatal outcome. Areas covered: Over the past 15 years, much has evolved. Tyrosine kinase inhibitors completely changed the prognosis of Ph-positive ALL. In addition, the geneti…

There is an unmet need for treatment options for acute lymphoblastic leukemia (ALL) patients who have relapsed on multiple prior therapies. Thomas Alexander, MD, PhD, of the University of North Caroli…

Publication date: Available online 9 August 2018Source: Journal of the Chinese Medical AssociationAuthor(s): Chien-Ting Chen, Jyh-Pyng Gau, Jing-Hwang Liu, Tzeon-Jye Chiou, Liang-Tsai Hsiao, Yao-Chung LiuAbstractBackgroundAcute lymphoblastic leukemia (ALL) remains one of the most difficult-to-cure hematological malignancies. Allogeneic hematopoietic stem cell transplantation (HSCT) provides curative potential but a substantial proportion of patients eventually will relapse. It is unknown if there are any modifiable factors exists that could improve survival or predict relapse immediately after HSCT is unknown. The aim of t…

Subacute combined degeneration of the spinal cord (SACD) is a rare neurologic disorder manifesting progressive symptoms of paresthesia and spastic paralysis. Herein we present an autopsy case of SACD caused by folic acid and copper deficiency. A 16-year-old male presented with gradually worsening unsteady gait, and bladder and rectal dysfunction. He had a medical history of T-cell acute lymphoblastic leukemia (T-ALL), diagnosed 1.5  years previously. The patient had undergone chemotherapy, including methotrexate, as well as allogeneic bone mallow transplantation.

AbstractThe intravenous CD22-directed antibody drug conjugate inotuzumab ozogamicin (Besponsa®) is approved in several countries including in the USA, EU and Japan, as monotherapy for the treatment of adults with relapsed/refractory B-cell acute lymphoblastic leukaemia (ALL). In adults with relapsed/refractory B-cell ALL who had received one or two prior treatment regimens, inotuzumab ozogamicin was associated with significantly higher rates of complete remission (including complete remission with incomplete haematological recovery) [CR/CRi] than standard therapy in the pivotal INO-VATE ALL trial. Inotuzumab ozogamicin…

UCLA Health has joined an important national clinical trial that uses genetic testing to match people who have acute myeloid leukemia, or AML, with new therapies. UCLA ’s hospital system is the first in California to offer people the opportunity to participate.The Beat AML Master Trial will evaluate a precision-based medicine approach to treating the disease; it will allow people with the disease to have immediate access to new treatments that are currently in development without having to try more traditional approaches first. The approach could streamline a patient ’s course of treatment and, ultimately, save…

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…
