Un equipo de investigadores japoneses ha desarrollado una tecnolog\u00eda de radioterapia con neutrones que destruye solo las c\u00e9lulas malignas en los casos de tumor cerebral sin da\u00f1ar el tejido sano, inform\u00f3 el diario Nikkei.<\/p>\n

\"\"<\/a>El equipo, formado por cient\u00edficos del Colegio M\u00e9dico de Osaka, la Universidad de Kyoto, la farmac\u00e9utica Stella Pharma y el conglomerado Suimoto Heavy Industries, ha basado esta t\u00e9cnica experimental en la llamada captura neutr\u00f3nica de boro (BCNT).
\nLa t\u00e9cnica consiste en utilizar un acelerador de part\u00edculas, que ocupa unos 3 metros de ancho y cuyo precio oscila entre 2.000 y 3.000 millones de yenes (entre 20 y 30 millones de euros), en lugar de un reactor para crear los neutrones destinados a la terapia. Los investigadores han presentado una solicitud para realizar ensayos cl\u00ednicos utilizando la tecnolog\u00eda en pacientes que hayan sufrido una reca\u00edda en casos de glioblastoma, el tumor cerebral m\u00e1s agresivo, con \u00edndices de supervivencia muy bajos.\"\"<\/a>
\nA los pacientes se les inyectar\u00e1 un compuesto qu\u00edmico con boro, elemento que se concentra preferentemente en las c\u00e9lulas tumorales. La irradiaci\u00f3n de neutrones provoca que el boro emita una fuerte radiaci\u00f3n, al entrar en reacci\u00f3n, que destruye \u00fanicamente las c\u00e9lulas cancer\u00edgenas.
\nEn una hora del nuevo tratamiento, los pacientes reciben una dosis de radiaci\u00f3n del doble o el triple de lo que normalmente reciben en una terapia de seis semanas. M\u00e1s de 120 universitarios han realizado estudios con el reactor nuclear experimental de la Universidad de Kioto, con resultados en los que, en algunos casos, el tumor cerebral se ha reducido hasta en un 70 por ciento.<\/p>\n

\"\"<\/a>Seg\u00fan el Ministerio nip\u00f3n de Sanidad, en 2010 unas 353.000 personas murieron de c\u00e1ncer en Jap\u00f3n, lo que supone uno de cada tres fallecimientos en el archipi\u00e9lago.<\/p>\n
