Very high-energy electrons could prove optimal for FLASH radiotherapy
- Electron therapy has long been important in cancer treatments, with energies up to 20 MeV ideal for certain applications.
- Very high-energy electrons (VHEEs) with energies up to 400 MeV could revolutionize radiation treatments.
- THERYQ aims to make VHEE-based treatments a reality by adapting CERN technology for clinical use.
- VHEEs offer deep penetration, narrow beam edges, and robustness against tissue density variations.
- Electromagnetic scanning allows precise manipulation of VHEE beams with smaller footprint and cost.
- VHEE beams enable FLASH radiotherapy, delivering ultrahigh dose rates while reducing normal tissue toxicity.
- Clinical trials with FLASH radiotherapy show promise, with initial focus on skin lesions progressing to deeper tumors.
- VHEEs could be particularly beneficial for radioresistant cancers, sparing normal tissue while increasing target doses.
- Technological challenges remain, but the goal is to make VHEE accelerators compact and practical for clinical use.
- The potential of VHEEs for FLASH radiotherapy brings hope for improved cancer treatments in the future.
