There are more than 100 types of primary central nervous system(CNS)tumors according to the 2021 WHO classification, but the incidence of primary CNS tumors, including all of these types, is very low. As a result, there are only a limited number of tumors for which evidence-based treatment strategies have been established, in particular, there is little evidence regarding irradiation methods and prescribed doses of radiotherapy. In this article, we describe the following radiation therapies for primary CNS tumors:whole ventricle irradiation for intracranial germinomas, craniospinal irradiation for medulloblastomas, and extended local/local irradiation for glioblastomas. In addition, we will describe the points to be noted for target delineation for these radiotherapy methods and will be take care when performing high-precision radiotherapy, such as proton beam therapy and intensity modulated radiation therapy(IMRT), with my personal opinion.
