Radiosurgery for intracranial lesions is evolving. While effective for arteriovenous malformations (AVMs), more data is needed to link angiographic response to hemorrhage risk. Accurate treatment planning and reporting are crucial for future advancements.

Area of Science:

  • Neurosurgery
  • Radiation Oncology
  • Medical Physics

Background:

  • Radiosurgery for intracranial lesions has a 30-year history with evolving applications.
  • Favorable angiographic response rates are reported for arteriovenous malformations (AVMs), but the link to hemorrhage risk requires further investigation.
  • Current retrospective data for non-AVM lesions are insufficient for firm conclusions.

Purpose of the Study:

  • To evaluate the evolving role of radiosurgery in treating intracranial lesions.
  • To highlight the need for better correlation between objective response measures and clinical outcomes, such as hemorrhage risk.
  • To emphasize the importance of standardized reporting for future radiosurgery studies.

Main Methods:

  • Review of existing retrospective data on radiosurgery for intracranial lesions.

  • Discussion of technical challenges in accurately defining treatment volumes and delivering radiation doses.
  • Analysis of reporting standards for clinical trials and non-trial settings.

    • Main Results:

    • Accurate dose deposition is achievable, but defining the target volume remains a significant challenge, independent of the radiosurgical technique.
    • Existing retrospective data for non-AVM lesions do not permit definitive conclusions.
    • Standardized and detailed reporting of patient data, treatment parameters, and outcomes is essential for meaningful interpretation of results.

    Conclusions:

    • Radiosurgery's role in intracranial lesion treatment is still developing, particularly for AVMs where the link between angiographic response and hemorrhage risk needs clarification.
    • Technical challenges in target volume definition and the need for comprehensive, standardized reporting are critical for advancing the field.
    • Future research should focus on improving data collection and analysis to better understand radiosurgery's efficacy and safety across various intracranial pathologies.
