Anticonvulsant Prophylaxis and Steroid Use in Adults With Metastatic Brain Tumors
Based on guidelines from the Congress of Neurological Surgeons, also endorsed by ASCO and SNO.
Anticonvulsants
Prophylactic antiepileptic drugs are not recommended for routine use in patients with brain metastases who did not undergo surgical resection and who are otherwise seizure free.
Steroid Therapy vs No Steroid Therapy
For asymptomatic brain metastases patients without mass effect, insufficient evidence exists to make a treatment recommendation for this clinical scenario.
For brain metastases patients with mild symptoms related to mass effect, corticosteroids are recommended to provide temporary symptomatic relief of symptoms related to increased intracranial pressure and edema secondary to brain metastases. It is recommended for patients who are symptomatic from metastatic disease to the brain that a starting dose of dexamethasone 4 to 8 mg/day be considered.
For brain metastases patients with moderate to severe symptoms related to mass effect, corticosteroids are recommended to provide temporary symptomatic relief of symptoms related to increased intracranial pressure and edema secondary to brain metastases. If patients exhibit severe symptoms that are consistent with increased intracranial pressure, it is recommended that higher doses, such as 16 mg/day or more, be considered.
