Summary

Radiosurgery offers excellent control rates (90-95%) for benign brain tumors called meningiomas. This effective treatment minimizes side effects and is suitable for various patient scenarios, including recurrent or partially resected tumors.

Area of Science:

  • Neurosurgery
  • Radiation Oncology
  • Oncology

Background:

  • Meningiomas are the second most common primary brain tumors, arising from the dura mater.
  • They are typically slow-growing and benign.
  • Effective treatment strategies are crucial due to their prevalence.

Purpose of the Study:

  • To evaluate the efficacy and safety of radiosurgery for treating meningiomas.
  • To highlight radiosurgery as a viable option for specific meningioma patient populations.

Main Methods:

  • Utilizing highly conformal radiation plans for precise tumor targeting.
  • Administering single-fraction radiation to achieve a high biologically effective dose.
  • Assessing treatment outcomes based on tumor control rates and patient morbidity.

Main Results:

  • Meningioma tumor control rates achieved between 90% and 95%.
  • Low risk of treatment-related morbidity observed.
  • Radiosurgery demonstrated effectiveness in managing asymptomatic, small- to moderate-sized meningiomas.

Conclusions:

  • Radiosurgery is an excellent treatment option for select meningiomas.
  • It is particularly beneficial for patients with incompletely resected or recurrent tumors.
  • The technique offers effective tumor control with minimal harm to surrounding brain tissue.
