Resection versus radiosurgery for patients with brain metastases

Area of Science:

• Neuro-oncology
• Cancer Metastasis Research
• Radiation Oncology

Background:

• Brain metastases are a common complication in adult cancer patients, affecting 20-40% and showing an increasing incidence.
• Despite treatment advances, the prognosis for patients with brain metastases remains poor, with a median survival of approximately 4 months.

Purpose of the Study:

• To review the current standard of care for brain metastases.
• To evaluate the efficacy of focal treatments for single versus multiple brain metastases.
• To explore future directions in the treatment of brain metastases.

Main Methods:

• Review of randomized trials and current clinical practices for brain metastases.
• Analysis of survival data for patients treated with whole brain radiation therapy, resection, and radiosurgery.
• Discussion of emerging therapeutic strategies.

Main Results:

• Whole brain radiation therapy is the standard of care for most patients.
• Focal treatments like resection and radiosurgery significantly improve survival in patients with a single brain metastasis.
• The survival benefit of focal treatments for patients with multiple brain metastases is currently unclear.

Conclusions:

• While focal treatments offer survival benefits for single brain metastases, their utility in multifocal disease requires further investigation.
• Future research should focus on advanced imaging, patient selection, systemic therapies, and targeted/antiangiogenic agents for improved brain metastases treatment.
• Optimizing treatment strategies for brain metastases is crucial for improving patient outcomes.
