\"\"<\/a>\u201cFundamentalmente el\u00a0ayuno\u00a0no es una cuesti\u00f3n de est\u00f3mago, sino de coraz\u00f3n.\u201d<\/em> San Agust\u00edn<\/h2>\n

Un nuevo estudio publicado en \u2018PLOS One\u2019, realizado por investigadores de la Universidad del Sur de California (USC), ha sido el primero en mostrar que el ayuno controlado mejora la eficacia de la radioterapia en el tratamiento del c\u00e1ncer, extendiendo la esperanza de vida en ratones con tumores cerebrales agresivos.<\/p>\n

El trabajo previo del autor principal Valter Longo, profesor de Gerontolog\u00eda y Ciencias Biol\u00f3gicas en la USC y director del Instituto de Longevidad de Escuela de Gerontolog\u00eda en USC Davis, hab\u00eda demostrado que, a corto plazo, el ayuno protege a las c\u00e9lulas sanas, mientras que las c\u00e9lulas cancerosas se vuelven vulnerables a los t\u00f3xicos efectos de la quimioterapia.<\/p>\n

Ahora, el nuevo estudio ha sido el primero en mostrar que los per\u00edodos de ayuno parecen tener el mismo efecto en aumentar la radioterapia en el tratamiento del glioma, el tumor cerebral m\u00e1s com\u00fanmente diagnosticado.\"\"<\/a><\/p>\n

\u201cEn nuestra investigaci\u00f3n inicial con quimioterapia analizamos la manera de proteger a los pacientes contra la toxicidad. En esta nueva investigaci\u00f3n sobre la radiaci\u00f3n buscamos averiguar cu\u00e1les son las condiciones que hacen al c\u00e1ncer m\u00e1s susceptible al tratamiento, y c\u00f3mo podemos reproducirlas\u201d, explica Longo.<\/p>\n

Los investigadores estudiaron la combinaci\u00f3n del ayuno con la radioterapia y el f\u00e1rmaco de quimioterapia temozolomida, en la actualidad el tratamiento est\u00e1ndar para el tratamiento de tumores cerebrales en adultos, despu\u00e9s de un intento de extirpaci\u00f3n quir\u00fargica.<\/h2>\n

\"\"<\/a>Los expertos observaron que, controlando el ayuno a corto plazo en los ratones, en ciclos de no m\u00e1s de 48 horas, mejoraba la eficacia de la radiaci\u00f3n y la quimioterapia en el tratamiento de los gliomas. A pesar del crecimiento extremadamente agresivo del tipo de tumor cerebral estudiado, sobrevivieron hasta el final del estudio m\u00e1s ratones que ayunaron y recibieron terapia de radiaci\u00f3n, que los que solo recibieron radiaci\u00f3n sola o solo ayunaron.<\/p>\n

\u201cLos resultados demuestran el papel beneficioso del ayuno en el tratamiento de los gliomas con quimioterapia\"\"<\/a> y radioterapia est\u00e1ndar\u201d, se\u00f1alan los investigadores, quienes a\u00f1aden que los resultados indican los beneficios del ayuno controlado a corto plazo en las personas que reciben tratamiento para los tumores cerebrales.<\/p>\n

Longo advierte que los pacientes deben consultar con su onc\u00f3logo antes de emprender cualquier ayuno.<\/p>\n
