Background: A heterogeneous geographic distribution of childhood acute lymphoblastic leukemia (ALL) cases has been described, possibly, related to the presence of different environmental factors. The aim of the present study was to explore the geographical distribution of childhood ALL cases in Greater Mexico City (GMC).
Methods: A population-based case-control study was conducted.
NK cells with decreased expression of multiple activating receptors is a dominant phenotype in pediatric patients with acute lymphoblastic leukemia.

NK cells have unique attributes to react towards cells undergoing malignant transformation or viral infection. This reactivity is regulated by activating or inhibitory germline encoded receptors. An impaired NK cell function may result from an aberrant expression of such receptors, a condition often seen in patients with hematological cancers.

- Acute lymphoblastic leukemia (ALL) is linked to both genetic and environmental factors, with single nucleotide polymorphisms (SNPs) in specific genes potentially increasing risk in pediatric populations in Mexico.
- A multicenter study was conducted comparing children diagnosed with ALL to healthy controls, examining the impact of SNPs rs2910164, rs12803915, rs11614913, and rs3746444 through DNA analysis.
- The results indicated a significant association of the rs3746444 SNP with a higher risk of developing ALL, particularly in males, highlighting the need for further research on the genetic mechanisms behind ALL.
Genotype-Environment Interaction Analysis of NQO1, CYP2E1, and NAT2 Polymorphisms and the Risk of Childhood Acute Lymphoblastic Leukemia: A Report From the Mexican Interinstitutional Group for the Identification of the Causes of Childhood Leukemia.

Acute lymphoblastic leukemia (ALL) is the main type of cancer in children. In Mexico and other Hispanic populations, the incidence of this neoplasm is one of the highest reported worldwide. Functional polymorphisms of various enzymes involved in the metabolism of xenobiotics have been associated with an increased risk of developing ALL, and the risk is different by ethnicity.

August 2020
Article Synopsis
- - The study aimed to explore the relationship between parental age at conception and the risk of childhood acute leukaemia (AL) among Mexican children, given the high incidence of the disease in that population.
- - A multicenter case-control approach was used, comparing children diagnosed with AL to matched controls, and applying statistical analysis to investigate the impacts of maternal and paternal ages on this risk.
- - The findings revealed minimal associations between parental ages and childhood AL, though a higher risk for acute myeloid leukaemia (AML) was noted when mothers were 20-24 years old, and some association for acute lymphoblastic leukaemia (ALL) with younger mothers and fathers.
A greater birthweight increases the risk of acute leukemias in Mexican children-experience from the Mexican Interinstitutional Group for the Identification of the Causes of Childhood Leukemia (MIGICCL).

In Mexico, due to the high rates of diabetes, overweight, and obesity, there has also been noted an increased newborn weight, which may be contributing to the elevated incidence rate of childhood acute leukemia (AL). We conducted a case-control study in public hospitals of Mexico City aimed to know whether a greater weight at birth is associated with a higher risk of developing leukemia. We included incident cases with acute lymphoblastic leukemia (ALL) and acute myeloid leukemia (AML) diagnosed between 2010 and 2015.
