Chimeric Antigen Receptor T Cells for B-Cell Acute Lymphoblastic Leukemia
Chimeric antigen receptor (CAR) T-cell therapy is transforming the landscape for treatment of B-lineage acute lymphoblastic leukemia (B-ALL). Chimeric antigen receptor T-cell therapy makes use of T cells that have been modified to target a cancer-specific cell surface antigen. There is currently 1 Food and Drug Administration–approved CD19-directed CAR T-cell therapy for relapsed/refractory B-ALL with numerous other CAR T-cell products under clinical investigation. This review covers the development of CAR T cells for B-ALL, citing the remarkable efficacy of inducing remissions in a very high-risk population of patients. However, following the first round of CAR T-cell trials targeting CD19 in B-ALL, it has been found that approximately 50% of patients who initially respond will ultimately recur. Current efforts in the field are focusing on the identification of targets beyond CD19 as well as advancing strategies to promote more durable remissions as work is ongoing to move this therapy upfront.
ConclusionThe findings indicate that 20(S)-GRh2 exhibits beneficial effects against T-ALL through the PI3K/Akt/mTOR pathway and could be a natural product of novel target for T-ALL therapy.

JazaeriAbstractThe involvement of the cervix as a site of relapse for hematologic malignancies is rare. We herein present a case of relapsed B-cell Acute Lymphoblastic Leukemia/Lymphoma (ALL) mimicking advanced cervical cancer. The patient is a 61-year-old female with history B-cell ALL and had multiple relapses confined to the bone marrow and had received several different chemotherapy regimens. She presented with lower abdominal pain after the...
Conclusions: Maternal folic acid supplementation was found to have a protective effect against childhood acute lymphoblastic leukaemia. Thus, healthcare professionals are recommended to provide regular health education and health promotion to the community on the benefits of folic acid supplementation during pregnancy.

Abstract CAR T cell therapy of cancers promises to revolutionize oncology by harnessing the powers of synthetic biology and immunotherapy in a single agent. CARs are synthetic receptors composed of an extracellular antigen binding domain and one or more intracellular signaling domains which act in concert to activate the T cell upon antigen recognition. CARs targeting B cell associated CD19 demonstrated robust in vivo cytolytic activity, expansion, and persistence upon antigen exposure paving the way for clinical application of this technology and ultimately FDA approval for pediatric and young adult acute lymphob...
ConclusionAsparaginase is a common cause of antineoplastic-induced liver injury with jaundice, typically with short latency, marked steatosis, and prolonged jaundice, which can lead to delays in antileukemic therapy. The cause of injury is likely direct inhibition of hepatic protein synthesis caused by asparagine depletion.
