Además, señalaron que este hallazgo ayuda a explicar por qué los casos de cáncer esofágico han aumentado entre los varones blancos en los últimos años, pues una importante proporción de portadores de la bacteria han sido tratados para erradicarla, perdiendo de ese modo la protección potencial que pueda ofrecer.
En su estudio examinaron datos correspondientes a 130.000 pacientes. Un total de 52 habían desarrollado adenocarcinoma de esófago. Investigaron en muestras de sangre cuántos pacientes presentaban infección por H. pylori y compararon los resultados con los de 551 controles sin cáncer. De ese modo, concluyen que los individuos infectados presentan un 70% menos riesgo de desarrollar cáncer de esófago que los no infectados.
