Brain tumors

Brain tumors are a set of different diseases, which represent 20% of all childhood cancers: gliomas, medulloblastomas, rhabdoid tumors… These are the most frequent solid tumors in children. They are also those for which therapeutic progress has been the least important in recent decades. The survival rate of children with brainstem tumors has hardly changed over the last decades: it is less than 1% over 5 years.
