Susceptibilidad genética y riesgo de cáncer gástrico en una población del Cauca.

Abstract: El cáncer gástrico es la principal causa de mortalidad por cáncer en Colombia. El riesgo de desarrollar cáncer gástrico se ha asociado con factores ambientales y con la infección por Helicobacter pylori. Las enzimas glutatión-S-transferasas están involucradas en la desintoxicación de varios carcinógenos ambientales. Las deleciones homocigóticas de glutatión-S-transferasa M1 (GSTM1-0) y glutatión-S-transferasa T1 (GSTT1-0) se han asociado con algunos tipos de cáncer. Los niveles del factor de necrosis tumoral (… Show more

“…In Colombia, where incidence of gastric cancer is high, few studies have sought to correlate some environmental and genetic susceptibility factors with the risk of acquiring this neoplasia [ 38 ]. The patients’ group in this study had a mean age of 61.8 ± 12.9 years, where 70.6% of the cases corresponded to the male gender, data consistent with that reported at the national level based on Cancer Population Records and statistics from the National Statistics Department (DANE, for the term in Spanish), revealing a male: female ratio of 1.8:1 [ 3 ].…”

“…These DNA changes are transmissible from one generation to another, detectable in at least 1% of individuals in a population and could explain the differences between individuals in the susceptibility to some multigenic, complex diseases like Covid19. 11,12 Two main approaches can be used in genetic epidemiology to establish a link between genetic variations and the risk of developing a disease: Genetic linkage analysis and association studies (candidate gene and genome-wide association studies). 13 Angiotensin-converting enzyme (chromosome Xp22.2) is the enzyme responsible for converting angiotensin-2 to angiotensin (1-7) form, 14 it is expressed in most organs such as, thyroid and lungs, heart, esophagus, kidney, adipose tissue, liver, retina, the vascular system, the small intestine, nasal and bronchial tissue, and alveolar type II epithelial cells.…”

“…El presente estudio encontró significativamente elevados los niveles de las siete citocinas en comparación al grupo control, aunque no en asociación estadísticamente significativa a infección por H. pylori, identificada por la positividad a anticuerpos IgG circulantes, sabiendo que las limitaciones de estas pruebas, como el no diferenciar una infección actual de una infección pasada y la falta de pruebas fabricadas con antígenos locales, que identifiquen anticuerpos contra antígenos de cepas autóctonas, aunque la sensibilidad de la detección de IgG anti H. pylori se ha reportado tener sensibilidad y especificidad del 90% (Malfertheiner et al, 2016). Así mismo se deben considerar otros de factores que inciden en el desarrollo del CG, siendo según la literatura los más relevantes, la virulencia de las cepas de H. pylori y la producción de toxinas CagA, la carga genética de hospedero que incluye polimorfismos de citocinas (Chiurillo, 2014;El-Omar et al, 2000;Petrovich, 2016;Torres, 2004) así como factores epigenéticos (Vahid & Davoodi, 2021).…”
