Busulfan is a cytotoxic agent used in preconditioning for hematopoietic stem cell transplantation (HSCT). Therapeutic drug monitoring of busulfan is necessary owing to its narrow therapeutic range. Patients undergoing preconditioning are susceptible to infection and might require co-administration of antibiotics. We present a case study of a three-year-old girl with precursor T-cell acute lymphoblastic leukemia who received intravenous busulfan before HSCT. Metronidazole was co-administered before the third dose of busulfan because of Clostridium difficile infection...

Acute lymphoblastic leukemia (ALL) in the adolescent and young adult (AYA) population is a difficult clinical problem. The AYA population, generally regarded as patients aged 15 to 39 years, currently draws a good deal of attention, particularly in the area of therapy selection. The current trend is to treat this group of patients with leukemia regimens based on pediatric protocols, and results comparing pediatric approaches versus adult approaches to treatment are maturing. Results are pending from a large US trial in which pediatric-based treatment is given to AYA patients with ALL...

A 56-year-old man being treated for dilated cardiomyopathy presented with epigastralgia. He was diagnosed with ventricular tachycardia and Philadelphia chromosome-positive acute lymphoblastic leukemia. After treating incessant ventricular tachycardia, we commenced induction therapy for leukemia with dasatinib and prednisolone to minimize toxicity towards cardiomyocytes and the cardiac conduction system. Although dasatinib was temporarily withheld because of a recurrence of ventricular tachycardia, we rechallenged dasatinib while using bisoprolol and amiodarone and achieved a complete hematological response three weeks later...

Using CRISPR/Cas9 technology, researchers have devised a method to deliver a CAR gene to a specific locus, TRAC, in T cells. This targeted approach yielded therapeutic cells that were more potent even at low doses; in a mouse model of acute lymphoblastic leukemia, they outperformed CAR T cells created with a randomly integrating retroviral vector.

Monitoring of minimal residual disease (MRD) is currently considered the most powerful predictor of outcome in acute lymphoblastic leukemia (ALL). Achievement of a negative MRD state assessed by multicolor flowcytometry (MFC) is an important predictor of disease-free survival (DFS) and overall survival (OS) in ALL patients. We sought to determine whether panels of antibodies combination are more suitable for detection of MRD in Childhood ALL. Eighty-four (84) patients with ALL (B-lineage subtype) were enrolled in this study...

T-cell acute lymphoblastic leukemia (T-ALL) is an aggressive hematopoietic neoplasm resulting from the malignant transformation of T-cell progenitors, and comprises approximately 15 and 25% of pediatric and adult ALL cases respectively. It is well-established that activating NOTCH1 mutations are the major genetic lesions driving T-ALL in most patients, but efforts to develop targeted therapies against this pathway have produced limited success in decreasing leukemic burden and come with significant clinical side effects...

A 10-year-old girl was referred to our hospital with left preauricular adenopathy and gingival swelling. She was diagnosed with B-cell precursor acute lymphoblastic leukemia (BCP-ALL) based on being positive for expressions of CD10, CD19, TdT and HLA-DR. She showed no CD20 expression at the time of diagnosis. Based on the initial diagnosis of BCP-ALL, induction chemotherapy for BCP-ALL was initiated. However, the blasts did not disappear from her peripheral blood. Bone marrow examination on day 33 identified 81...

OBJECTIVES: Associations between parental occupational pesticide exposure and childhood acute lymphoblastic leukemia (ALL) vary across studies, likely due to different exposure assessment methodologies. METHODS: We assessed parental occupational pesticide exposure from the year before pregnancy to the child's third year of life for 669 children diagnosed with ALL and 1021 controls. We conducted expert rating using task-based job modules (JM) to estimate exposure to pesticides among farmer workers, gardeners, agricultural packers, and pesticide applicators...

Chromosome instability (CIN) is deleterious to normal cells because of the burden of aneuploidy. However, most human solid tumors have an abnormal karyotype implying that gain and loss of chromosomes by cancer cells confers a selective advantage. CIN can be induced in the mouse by inactivating the spindle assembly checkpoint. This is lethal in the germline but we show here that adult T cells and hepatocytes can survive conditional inactivation of the Mad2l1 SAC gene and resulting CIN. This causes rapid onset of acute lymphoblastic leukemia (T-ALL) and progressive development of hepatocellular carcinoma (HCC), both lethal diseases...

REVIEW
Rochelle R Maxwell, Peter D Cole
PURPOSE OF REVIEW: The aim of this review is to summarize the most recent and most robust pharmacogenetic predictors of treatment-related toxicity (TRT) in childhood acute lymphoblastic leukemia (ALL). RECENT FINDINGS: Multiple studies have examined the toxicities of the primary chemotherapeutic agents used to treat childhood ALL in relation to host genetic factors. However, few results have been replicated independently, largely due to cohort differences in ancestry, chemotherapy treatment protocols, and definitions of toxicities...

Activating mutations of NOTCH1 (a well-known oncogene in T-cell acute lymphoblastic leukemia) are present in ∼4-13% of chronic lymphocytic leukemia (CLL) cases, where they are associated with disease progression and chemorefractoriness. However, the specific role of NOTCH1 in leukemogenesis remains to be established. Here, we report that the active intracellular portion of NOTCH1 (ICN1) is detectable in ∼50% of peripheral blood CLL cases lacking gene mutations. We identify a "NOTCH1 gene-expression signature" in CLL cells, and show that this signature is significantly enriched in primary CLL cases expressing ICN1, independent of NOTCH1 mutation...

The aim of the present study was to evaluate in patients with acute lymphoblastic leukemia (ALL), the oxidative status and antioxidant defense and its involvement in the relapse of ALL. The plasmatic levels of malondialdehyde, advanced oxidation of protein products and reduced glutathione (GSH), and the plasmatic activities of catalase, superoxide dismutase (SOD), and glutathione peroxidase were determined in 34 patients who were newly diagnosed with ALL and compared with 92 healthy individuals. The plasmatic concentrations of malondialdehyde and advanced oxidation of protein products were higher in ALL patients than in controls and increased during chemotherapy...

Acute graft vs. host disease remains a major threat to successful outcome after allogeneic hematopoietic cell transplantation. While improvements in treatment and supportive care have occurred, it is unknown whether these advances have resulted in improved outcome specifically among those diagnosed with acute graft vs. host disease. We examined outcome following diagnosis of grade II-IV acute graft vs. host disease according to time period, and examine effects according to original graft vs. host disease prophylaxis regimen and maximum overall grade of acute GVHD...
