Advancements in adaptive MR-guided radiotherapy for high-grade gliomas

Abstract

Glioblastoma multiforme (GBM) is the most common primary malignancy of the central nervous system, with a poor prognosis despite multimodal treatment approaches. With the development and integration of Magnetic Resonance-guided Linear Accelerator (MR-Linac) technology into the treatment paradigm for high-grade gliomas, there is promising potential for improved treatment precision and reduced side effects for patients diagnosed with this aggressive cancer. The MR-Linac combines high-resolution, real-time magnetic resonance imaging with precise linear accelerator-based treatment delivery, enabling adaptive radiotherapy that adjusts to anatomical changes during the treatment course. This technology offers the potential to refine target delineation, optimize treatment volumes, and reduce radiation exposure to healthy tissue. The editorial discusses the transformative potential of the MR-Linac in improving treatment personalization and outcomes for patients with high-grade gliomas, positioning it as a significant advancement in radiation oncology.
