The rationale for the use of radiation therapy is essentially the same for first-line therapy or at the time of recurrence. For more information, see the Radiation therapy section. If the child has never received radiation therapy, local radiation therapy may be a treatment option, although chemotherapy in lieu of radiation should be considered, depending on the child's age and the extent and location of the tumor.[7][Level of evidence C1]; [8][Level of evidence C2]

Source links and citations

For children with low-grade gliomas for whom radiation therapy is indicated, conformal radiation therapy (including proton-beam therapy) approaches appear effective and offer the potential for reducing the acute and long-term toxicities associated with this modality.[9-12]
