- Abstract
Introduction: Over the years, the Hispanic population living in the United States has consistently shown high incidence rates of childhood acute leukemias (AL). Similarly, high AL incidence was previously observed in Mexico City (MC). Here, we estimated the AL incidence rates among children under 15 years of age in MC during the period 2010-2017., Methods: The Mexican Interinstitutional Group for the Identification of the Causes of Childhood Leukemia conducted a study gathering clinical and epidemiological information regarding children newly diagnosed with AL at public health institutions of MC. Crude age incidence rates (cAIR) were obtained. Age-standardized incidence rates worldwide (ASIRw) and by municipalities (ASIRm) were calculated by the direct and indirect methods, respectively. These were reported per million population <15 years of age; stratified by age group, sex, AL subtypes, immunophenotype and gene rearrangements., Results: A total of 903 AL cases were registered. The ASIRw was 63.3 (cases per million) for AL, 53.1 for acute lymphoblastic leukemia (ALL), and 9.4 for acute myeloblastic leukemia. The highest cAIR for AL was observed in the age group between 1 and 4 years (male: 102.34 and female: 82.73). By immunophenotype, the ASIRw was 47.3 for B-cell and 3.7 for T-cell. The incidence did not show any significant trends during the study period. The ASIRm for ALL were 68.6, 66.6 and 62.8 at Iztacalco, Venustiano Carranza and Benito Juárez, respectively, whereas, other municipalities exhibited null values mainly for AML., Conclusion: The ASIRw for childhood AL in MC is among the highest reported worldwide. We observed spatial heterogeneity of rates by municipalities. The elevated AL incidence observed in Mexican children may be explained by a combination of genetic background and exposure to environmental risk factors., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Flores-Lujano, Duarte-Rodríguez, Jiménez-Hernández, Martín-Trejo, Allende-López, Peñaloza-González, Pérez-Saldivar, Medina-Sanson, Torres-Nava, Solís-Labastida, Flores-Villegas, Espinosa-Elizondo, Amador-Sánchez, Velázquez-Aviña, Merino-Pasaye, Núñez-Villegas, González-Ávila, del Campo-Martínez, Alvarado-Ibarra, Bekker-Méndez, Cárdenas-Cardos, Jiménez-Morales, Rivera-Luna, Rosas-Vargas, López-Santiago, Rangel-López, Hidalgo-Miranda, Vega, Mata-Rocha, Sepúlveda-Robles, Arellano-Galindo, Núñez-Enríquez and Mejía-Aranguré.)
