Acute lymphoblastic leukemia (ALL) consists of precursor B ALL or T ALL phenotypes. In the pediatric population, ALL patients enjoy an 80% long-term survival with the current pediatric chemotherapy protocols as compared with 50% long-term survival in the adult population. In adults, complete remission rates are similar to those of pediatric patients; however, long-term survival is much lower with the majority of deaths attributable to relapsed disease. Postremission consolidation strategies in adults include chemotherapy, autologous, or allogeneic transplant...

Height at diagnosis has been analyzed in connection with acute lymphoblastic leukemia (ALL). Most prior studies have compared cases to national reference data derived from previous birth cohorts. Our objective was to determine the association of height-for-age Z score (HAZ) at time of diagnosis with the odds ratio (OR) of ALL in a case-control study (N=498) with a contemporaneous population of age-matched, sex-matched, and ethnicity-matched controls. We hypothesized that cases would have greater mean HAZ at time of diagnosis/interview, after adjustment for weight-for-age (WAZ) and weight-for-height (WHZ)...

L-Asparaginase (L-Asp) is an enzyme that catalyzes the hydrolysis of L-asparagine to L-aspartic acid, and its depletion induces leukemic cell death. L-Asp is an important component of treatment regimens for Acute Lymphoblastic Leukemia (ALL). Sensitivity to L-Asp is due to the absence of L-Asparagine synthetase (ASNS), the enzyme that catalyzes the biosynthesis of L-asparagine. ASNS gene is located on 7q21.3, and its increased expression in ALLs correlates with L-Asp resistance. Chromosome 7 monosomy (-7) is a recurrent aberration in myeloid disorders, particularly in adverse-risk Acute Myeloid Leukemias (AMLs) and therapy-related myeloid neoplasms (t-MN), that leads to a significant downregulation of the deleted genes, including ASNS...

Manipulation of human NK cell repertoires promises more effective strategies for NK cell-based cancer immunotherapy. A subset of highly differentiated NK cells, termed adaptive NK cells, expands naturally in vivo in response to human cytomegalovirus (HCMV) infection, carries unique repertoires of inhibitory killer cell immunoglobulin-like receptors (KIRs), and displays strong cytotoxicity against tumor cells. Here, we established a robust and scalable protocol for ex vivo generation and expansion of adaptive NK cells for cell therapy against pediatric acute lymphoblastic leukemia (ALL)...

Five-year survival rates of pediatric acute lymphoblastic leukemia (ALL) have reached 90% in the developed countries. However, toxicity because of methotrexate (MTX) occurs frequently. Variety in the occurrence of toxicity is partly determined by single nucleotide polymorphisms (SNPs) in coding regions. Recently, five SNPs in non-coding pre-microRNAs and microRNA processing (miRNA) genes were identified in association with MTX-induced oral mucositis. This study aimed to replicate the association of these miRNA variants in relation to MTX-induced oral mucositis in a prospective childhood ALL cohort...

Three-quarters of the patients with acute lymphoblastic leukemia (ALL), show numerical or structural chromosomal alterations, which are important factors in leukemogenesis. The use of Multiplex Ligation-dependent Probes Amplification (MLPA) has been mainly limited for searching copy number alterations of genes, suggesting that MLPA could detect numerical alterations in cancer. However, the use of MLPA in pediatrics to analyze subtelomeric sequences for aneuploidy detection has not been considered in previous studies...

BACKGROUND: T-cell acute lymphoblastic leukemia (T-ALL) accounts for about 15% of pediatric ALL. With wider use of intensive chemotherapy, the prognosis for childhood T-ALL has improved. Further gains in treatment outcome will likely require methods to identify patients who continue to fail on contemporary protocols. This study aimed to evaluate pediatric patients with T-ALL at 2 different Arabic cancer centers regarding their clinicopathologic, immunophenotypic, and cytogenetic features and outcome...

Purpose Early thymic precursor (ETP) acute lymphoblastic leukemia (ALL) is an immunophenotypically defined subgroup of T-cell ALL (T-ALL) associated with high rates of intrinsic treatment resistance. Studies in children have shown that the negative prognostic impact of chemotherapy resistance is abrogated by the implementation of early response-based intensification strategies. Comparable data in adults are lacking. Patients and Methods We performed comprehensive clinicobiologic, genetic, and survival analyses of a large cohort of 213 adult patients with T-ALL, including 47 patients with ETP-ALL, treated in the GRAALL (Group for Research on Adult Acute Lymphoblastic Leukemia) -2003 and -2005 studies...

Conventional cytotoxic chemotherapy used to treat acute lymphoblastic leukemia (ALL) has resulted into high cure rates for pediatric patients, however outcomes for adult patients remain suboptimal. The 5-year overall survival is only 30-40% in adults and elderly patients with ALL compared to 90% in children. We have seen major advances in our understanding and management of ALL related to identification of new cytogenetic and molecular abnormalities and development of novel targeted agents for the treatment of ALL...

PEG-aspariginase is a backbone chemotherapy agent in pediatric acute lymphoblastic leukemia and in some non-Hodgkin lymphoma therapies. Nurses lack standardized guidelines for monitoring patients receiving PEG-asparaginase and for educating patients/families about hypersensitivity reaction risks. An electronic search of 6 databases using publication years 2000-2015 and multiple professional organizations and clinical resources was conducted. Evidence sources were reviewed for topic applicability. Each of the final 23 sources was appraised by 2 team members...

BACKGROUND AND AIM: Large prospective studies on dexamethasone-induced changes in eating behavior, energy, and nutrient intake are lacking in pediatric acute lymphoblastic leukemia (ALL). We prospectively studied eating behavior, energy, nutrient intake, and the effect on leptin and adiponectin levels during dexamethasone administration in children with ALL. PATIENTS: Parents of patients with ALL (3-16 years) completed a dietary diary for their child during 4 days of dexamethasone (6 mg/m(2) ) administration...

REVIEW
Jae Wook Lee, Bin Cho
The event-free survival (EFS) for pediatric acute lymphoblastic leukemia (ALL) has shown remarkable improvement in the past several decades. In Korea also, a recent study showed 10-year EFS of 78.5%. Much of the improved outcome for pediatric ALL stems from the accurate identification of prognostic factors, the designation of risk group based on these factors, and treatment of appropriate duration and intensity according to risk group, done within the setting of cooperative clinical trials. The schema of first-line therapy for ALL remains mostly unchanged, although many groups have now reported on the elimination of cranial irradiation in all patients with low rates of central nervous system relapse...

Dexamethasone is considered as a direct chemotherapeutic agent in the treatment of pediatric acute lymphoblastic leukemia (ALL). Beside the advantages of the drug, some problems arising from the dose-related side effects are challenging issues during the treatment. Accordingly, the classification of patients to dexamethasone sensitive and resistance groups can help to select optimizing the therapeutic dose with the lowest adverse effects particularly in sensitive cases. For this purpose, we investigated inhibited proliferation and induced cytotoxicity in NALM-6 cells, as sensitive cells, after dexamethasone treatment...
