Epilepsy in brain metastasis: an emerging entity.

Area of Science:

• Neuro-oncology
• Clinical Neurology
• Pharmacology

Background:

• Brain metastases represent a significant challenge in solid tumor management.
• Seizures are a common neurological complication, impacting patient quality of life.

Purpose of the Study:

• To review recent advancements in managing seizures associated with brain metastases.
• To provide guidance on antiepileptic drug (AED) selection and use.

Main Methods:

• Literature review of preclinical and clinical studies on brain metastases and seizures.
• Analysis of current treatment strategies and drug efficacy data.

Main Results:

• Melanoma and lung cancer patients face the highest seizure risk.
• Levetiracetam and valproic acid are considered appropriate AEDs; enzyme-inducing AEDs should be avoided due to drug interactions.
• Surgical resection offers complete seizure control; prophylactic AEDs are not recommended for seizure-naive patients.
• Seizures can be an adverse effect of treatments like stereotactic radiosurgery or chemotherapy.

Conclusions:

• Further research is needed to clarify AED efficacy and optimize seizure management in brain metastases.
• Clinical trials should investigate optimal treatment and prophylaxis strategies for seizures in this patient population.
