Early-age Acute Leukemia: Revisiting Two Decades of the Brazilian Collaborative Study Group
The understanding of leukemogenesis in early-age acute leukemia (EAL) has improved remarkably. Initiating somatic mutations detected in dried neonatal blood spots (DNBS) and in cord blood samples of affected children with leukemia have been proven to be acquired prenatally. However, to date, few epidemiological studies have been carried out exploring EAL that include infants and children 13 –24 months of age at the diagnosis. Maternal exposure to transplacental DNA-damaging substances during pregnancy has been suggested to be a risk factor for EAL. (Source: Archives of Medical Research)

Molecular Characterization of Pediatric Acute Myeloid Leukemia: Results of  a Multicentric Study in Brazil
The biological characterization of childhood acute myeloid leukemia (c-AML) is an important outcome predictor. In Brazil, very little is known about the frequency of AML subgroups, although c-AML accounts for about 18% of leukemias. We carried out this study to investigate the contribution of type I and II gene mutations in the probability of overall survival (pOS) of c-AML in Brazil. (Source: Archives of Medical Research)

Tobacco Smoke and Ras Mutations Among Latino and Non-Latino Children with Acute Lymphoblastic Leukemia
This study examined whether Ras mutation could define a unique etiologic group of childhood ALL associated with tobacco smoke, a well-established mutagen and carcinogen. (Source: Archives of Medical Research)

Environmental Exposure and Risk of Childhood Leukemia: An Overview
Childhood leukemia is the most common cancer diagnosed in children worldwide. However, only a few causes have been established so far, mainly some genetic syndromes and high doses of ionizing radiation. Major efforts have been undertaken to study the relationship between environmental factors and the risk of childhood leukemia, inspired by geographical variation in incidence rates. Some evidence has emerged for parental occupational exposures to pesticides, whereas there is less evidence for an association with postnatal pesticide exposure.

Analysis of Thiopurine S-Methyltransferase Deficient Alleles in Acute Lymphoblastic Leukemia Patients in Mexican Patients
It has been demonstrated that heterozygote and homozygote thiopurine S-methyltransferase (TPMT) mutant allele carriers are at high risk to develop severe  and potentially fatal hematopoietic toxicity after treatment with standard doses of 6-mercaptopurine (6-MP) and methotrexate (MX). Those drugs are the backbone of acute lymphoblastic leukemia (ALL) and several autoimmune disease treatments. We undertook this study to determine the frequency of the TPMT deficient alleles in children with ALL and non-ALL subjects from Mexico City and Yucatan, Mexico. (Source: Archives of Medical Research)

Copy Number Alterations Associated with Acute Lymphoblastic Leukemia in Mexican Children. A report from The Mexican Inter-Institutional Group for the identification of the causes of childhood leukemia
B-cell precursor acute lymphocytic leukemia (B-ALL) represents a worldwide public health issue. Particularly, Mexico is one of the countries with the highest incidence of ALL in children. Between the multiple factors involved in ALL etiology, genetic alterations are clearly one of the most relevant features. In this work, a group of 24 B-ALL patients, all negative for the four most frequent gene fusions (ETV6-RUNX1, BCR-ABL1, TCF3-PBX1 and MLL-AF4), were included in a high-resolution microarray analysis in order to evaluate genomic copy-number alterations (CNAs).

ARID5B, CEBPE and PIP4K2A Germline Genetic Polymorphisms and Risk of Childhood Acute Lymphoblastic Leukemia in Mexican Patients: A  MIGICCL Study
Childhood acute lymphoblastic leukemia (ALL) is the leading cause of childhood cancer-related deaths worldwide. Multiples studies have shown that ALL seems to be originated by an interaction between environmental and genetic susceptibility factors. The ARID5B polymorphisms are among the most reproducible ALL associated-risk alleles in different populations. The aim of the present study was to examine the contribution of ARID5B, CEBPE, and PIP4K2 risk alleles for the development of ALL in children from Mexico City and Yucatan, Mexico.

Analysis of Normal Hematopoietic Stem and Progenitor Cell Contents in Childhood Acute Leukemia Bone Marrow
Childhood acute leukemias (AL) are characterized by the excessive production of malignant precursor cells at the expense of effective blood cell development. The dominance of leukemic cells over normal progenitors may result in either direct suppression of functional hematopoiesis or remodeling of microenvironmental niches, contributing to BM failure and AL-associated mortality. We undertook this study to investigate the contents and functional activity of hematopoietic stem/progenitor cells (HSPC) and their relationship to immune cell production and risk status in AL pediatric patients.

Gene Expression Profiling of Acute Lymphoblastic Leukemia in Children with  Very Early Relapse
Acute lymphoblastic leukemia (ALL) is the most common childhood cancer worldwide. Mexican patients have high mortality rates, low frequency of good prognosis biomarkers (i.e., ETV6-RUNX1) and a high proportion is classified at the time of diagnosis with a high risk to relapse according to clinical features. In addition, very early relapses are more frequently observed than in other populations. The aim of the study was to identify new potential biomarkers associated with very early relapse in Mexican ALL children through transcriptome analysis. (Source: Archives of Medical Research)

Parental Exposure to Workplace Carcinogens and the Risk of Development of  Acute Leukemia in Infants. Case-Control Study
Occupational exposure of parents to carcinogens is of great interest in the etiology of leukemias. Evidence of the impact of such exposure on infants or small children is scarce. Here we estimated whether occupational exposure of parents to carcinogens could be a risk factor for leukemias in their children. (Source: Archives of Medical Research)

Results of Treating Childhood Acute Lymphoblastic Leukemia in a Low-middle Income Country: 10  Year Experience in Northeast Mexico
In high-income countries, treatment protocols for acute lymphoblastic leukemia (ALL) in children lead to a 5-year overall survival (OS) approaching 90%. There is scarce information on protocols and results of therapy from low-middle income countries (LMIC). We documented the results of treating children with ALL with two protocols in consecutive 5-year periods at a reference center in northeast Mexico. (Source: Archives of Medical Research)

Acute Leukemias in Children
Acute leukemia is the most common type of childhood cancer. Despite having a common term to denominate these diseases, it encloses several subtypes that, depending on their morphological, biological and molecular features, clinical presentation, response to chemotherapy and survival are determined.
