Summary
Stereotactic radiosurgery is effective for managing brain metastases and selected high-grade gliomas. This technique offers a low-morbidity alternative to surgery and brachytherapy for intracranial malignancies.
Area of Science:
- Neurosurgery
- Radiation Oncology
- Oncology
Background:
- Stereotactic radiosurgery (SRS) traditionally treats arteriovenous malformations and benign tumors.
- Recent applications include the multimodality management of intracranial malignancies.
Purpose of the Study:
- To evaluate the efficacy and safety of SRS in managing malignant intracranial neoplasms.
- To compare SRS with surgery and brachytherapy for brain metastases and gliomas.
Main Methods:
- Review of SRS application in intracranial malignancies.
- Comparison of SRS outcomes with surgical resection and brachytherapy.
Main Results:
- SRS is highly effective for small metastatic brain tumors, including those progressing after radiotherapy.
- SRS is a low-morbidity alternative to surgical resection for solitary brain metastases.
- For selected high-grade gliomas, SRS shows comparable tumor control, survival, and toxicity to brachytherapy, with added benefits of lower morbidity and cost.
Conclusions:
- Stereotactic radiosurgery is a valuable tool in the management of intracranial malignancies.
- SRS offers significant advantages over traditional treatments for specific brain tumor types.
- Further research is needed to optimize SRS protocols and define its definitive role in neuro-oncology.
