El c\u00e1ncer de pr\u00f3stata es el m\u00e1s frecuente en los hombres en Catalu\u00f1a. Se dan unos 5.000 casos nuevos cada a\u00f1o, por encima del de colon y recto (cerca de 4.000 casos) y el de pulm\u00f3n (3.500). Es un c\u00e1ncer muy asociado a la edad. El envejecimiento de la poblaci\u00f3n hace que su incidencia aumente cada a\u00f1o. Seg\u00fan las proyecciones del Plan Director de Oncolog\u00eda, en el a\u00f1o 2020 se producir\u00e1n unos 6.000 casos nuevos anuales.
A pesar de la elevada incidencia, es un tumor de lenta evoluci\u00f3n en la mayor\u00eda de casos, con una supervivencia del 84% a los cinco a\u00f1os, tambi\u00e9n seg\u00fan los datos del Plan Director de Oncolog\u00eda.
Muchos pacientes presentan un c\u00e1ncer de pr\u00f3stata de bajo riesgo, es decir, las c\u00e9lulas cancer\u00edgenas est\u00e1n confinadas en este \u00f3rgano y no se ha diseminado, los niveles de ant\u00edgeno prost\u00e1tico espec\u00edfico (PSA) son inferiores a 10 y la puntuaci\u00f3n de Gleason es inferior o igual a 6 (esta escala mide el grado de malignidad de las c\u00e9lulas).
En estos casos, hay cuatro posibles alternativas:
-Vigilancia activa (realizar revisiones peri\u00f3dicas sin intervenir) -Cirug\u00eda (Extirpaci\u00f3n de la pr\u00f3stata o de una parte) -Radioterapia Externa -Braquiterapia
El tratamiento con braquiterapia consiste en la colocaci\u00f3n de una fuente radioactiva- en este caso en forma de semillas de yodo-125-dentro o en la proximidad del tumor; la radiaci\u00f3n que emiten destruye las c\u00e9lulas malignas. Esta intervenci\u00f3n quir\u00fargica se hace una sola vez durante el tratamiento.
Varios estudios han demostrado que la braquiterapia es la t\u00e9cnica que conlleva menos efectos secundarios (generalmente disfunci\u00f3n urinaria y\/o sexual).
El estudio que se ha presentado muestra los resultados de supervivencia de 700 pacientes de c\u00e1ncer de pr\u00f3stata de bajo riesgo sometidos a braquiterapia. El trabajo concluye que la curaci\u00f3n (es decir, el control bioqu\u00edmico) a los cinco a\u00f1os es del 95% y, a los diez a\u00f1os, la supervivencia por causa espec\u00edfica (es decir, excluyendo las muertes por otras causas) es del 97%. Asimismo, se ha observado que los efectos secundarios son m\u00ednimos.<\/p>\n","protected":false},"excerpt":{"rendered":"
