NCT05512195

Brief Summary

Radiotherapy (RT) is one of the most important local treatments besides surgery, but currently, no consensus has been made regarding the optimal radiation volume for high grade gliomas. The most main growth characteristics of glioblastoma is infiltrative growth through the white matter tracts, regions along the white matter tracts especially at the direction of the main fiber bundles would have a higher risk of microscopic tumor cell dissemination. However, in current practice, recommends for the CTV definition is adding a 2 cm symmetrical margin to GTV or peritumoral edema in all directions, which hardly account for the growth characteristics of gliomas that are known from histopathological findings.
