Nature Communications<\/em><\/a>, muestran que al menos un 20% de la dosis efectiva de los f\u00e1rmacos, es suficiente para bloquear completamente la v\u00eda de se\u00f1alizaci\u00f3n y la proliferaci\u00f3n de las c\u00e9lulas, cuando se utiliza la combinaci\u00f3n de cuatro inhibidores. En los estudios in vitro con l\u00edneas celulares, as\u00ed como en los modelos animales generados mediante la implantaci\u00f3n de biopsias de pacientes en pulmones de ratones, se vieron respuestas duraderas a la terapia MLD sin toxicidad asociada. Aunque, cada f\u00e1rmaco por separado en dosis bajas no ten\u00eda ning\u00fan efecto, la combinaci\u00f3n de los cuatro implicaba un efecto sin\u00e9rgico que consegu\u00eda detener el crecimiento tumoral.<\/p>\nLos resultados de este estudio muestran que la combinaci\u00f3n de varios f\u00e1rmacos que act\u00faen sobre diferentes componentes de una v\u00eda de comunicaci\u00f3n necesaria para las c\u00e9lulas tumorales, y adem\u00e1s, hacerlo en dosis bajas, conlleva una eficacia a m\u00e1s largo plazo de los tratamientos antitumorales, y evita la aparici\u00f3n de resistencias por partes de las c\u00e9lulas tumorales. Aunque por el momento s\u00f3lo se ha probado en un tipo de tumores de pulm\u00f3n, los investigadores creen que esta nueva aproximaci\u00f3n podr\u00eda ser extensible a otros tipos de tumores. Se plantea iniciar ensayos cl\u00ednicos<\/strong> para comprobar la eficacia de esta estrategia en pacientes con tumores NSCLC portadores de la mutaci\u00f3n EGFR.<\/p>\nEste estudio ha contado tambi\u00e9n con la colaboraci\u00f3n de la Dra.
