Area of Science:

  • Neurosurgery
  • Radiation Oncology
  • Medical Physics

Background:

  • Modern brain radiosurgery has evolved over 50 years since its inception by Leksell.
  • It is now a common treatment for arteriovenous malformations, benign brain masses, and metastases.
  • The procedure provides an effective therapeutic option for life-threatening intracranial lesions with a favorable risk profile.

Purpose of the Study:

  • To review the historical development and current applications of brain radiosurgery.
  • To highlight the challenges and future potential of radiosurgery in neuro-oncology and neurovascular treatments.

Main Methods:

  • Historical review of radiosurgery development and applications.
  • Analysis of treatment efficacy and risks for various intracranial pathologies.
  • Discussion of technological advancements influencing treatment precision.

Main Results:

  • Brain radiosurgery is widely used, particularly since the 1990s, as both primary and adjuvant therapy.
  • The technique offers effective treatment for arteriovenous malformations, benign tumors, and metastatic lesions.
  • Challenges remain in defining treatment targets for primary brain cancers due to boundary definition difficulties.

Conclusions:

  • Brain radiosurgery is an established and effective treatment modality for specific brain conditions.
  • Ongoing advancements in imaging and computing are expected to enhance the precision and expand the applications of radiosurgery.
  • Future developments hold promise for overcoming current limitations, especially in treating primary brain malignancies.
