Gamma Knife Radiosurgery in a Single Fraction for Meningiomas Located in the Pineal Region
Overview
This study evaluates the outcomes of Gamma Knife Radiosurgery (GKRS) in 44 patients with pineal region meningiomas, highlighting long-term tumor control and safety. The findings suggest that GKRS is a viable treatment option for these challenging tumors, with promising results in local control and manageable adverse effects.
Background
Pineal region meningiomas are rare tumors that pose significant surgical challenges due to their location and relationship with critical neurovascular structures. Traditional microsurgical approaches can lead to severe complications, making GKRS an attractive alternative. This study aims to provide comprehensive data on the efficacy and safety of GKRS in this specific cohort, addressing a gap in the existing literature.
Data Highlights
No numerical data available in the provided source material.
Key Findings
44 patients with pineal region meningiomas were treated with single-fraction GKRS.
Local tumor control (LC) was defined as the absence of radiological progression at last follow-up MRI.
GKRS offers a minimally invasive treatment option compared to traditional microsurgery.
Long-term follow-up data indicate favorable outcomes in tumor control and safety.
Dosimetric constraints were established to minimize risks to critical structures, particularly the brainstem.
Clinical Implications
The findings support the use of GKRS as a primary or adjuvant treatment for pineal region meningiomas, particularly in patients where surgical resection poses high risks. Clinicians should consider GKRS for managing these tumors, given its favorable safety profile and effectiveness in achieving local control.
Conclusion
GKRS represents a significant advancement in the management of pineal region meningiomas, offering a safe and effective alternative to traditional surgical approaches. Further studies are warranted to validate these findings across larger cohorts.
