Resumen
Tumores en el sistema nervioso central (SNC) ocurren: intracranealmente (el cerebro) intraespinalmente (médula espinal, menos del 10%)
Los tumores cerebrales son los tumores sólidos más frecuentes entre los niños. Los astrocitomas constituyen el grupo más grande de estos tumores seguido de meduloblastomas y ependimomas.
Las localizaciones tumorales son diferentes en niños que en adultos. En los niños, casi la mitad de los tumores se localizan en la fosa craneal posterior a pesar de que solo el 15% de la masa de tejido en el sistema nervioso central se encuentra allí.
La mayoría de estos son tumores cerebrales. Los tumores cerebrales se distribuyen uniformemente desde el período del recién nacido hasta la adolescencia, y no hay una disminución significativa en la incidencia durante los años de la infancia, como lo hacen muchos otros tumores pediátricos. Los tumores cerebrales son algo más frecuentes en niños que en niñas. Un nuevo estudio muestra una relación de 1.29 de hombres a mujeres.Al tratar tumores intracraneales en niños, uno debe saber que el cerebro pediátrico no está completamente desarrollado. La tolerancia para la cirugía en niños es buena. Los efectos secundarios de la quimioterapia, y especialmente la radioterapia convencional, son graves.
Tumors in the central nervous system (CNS): intracranially (the brain) intraspinally (spinal cord, less than 10%) Brain tumors are the most frequent solid tumors among children. Astrocytomas are the largest group of these tumors followed by medulloblastomas and ependymomas. Tumor locations are different in children than in adults. In children, almost half of the lesions are located in the posterior cranial fossa despite the fact that 15% of the tissue mass in the central nervous system is there. The majority of these are brain tumors. Brain tumors are evenly distributed from the period of the newborn to adolescence, and there is no significant decrease in incidence during the childhood years, as do many other pediatric tumors. Brain tumors are more frequent in boys than in girls. A new study shows a ratio of 1.29 men to women. When treating intracranial tumors in children, one should know that the pediatric brain is not fully developed. Tolerance for surgery in children is good. The side effects of chemotherapy, and especially conventional radiotherapy, are tombs.
