Abstract
Up to date the brain tumors incidence keeps growing worldwide. Epilepsy and epileptic seizures are one of the most common clinical features of brain tumors. The aim of the study was to invent the algorithms antiepileptic treatment of patients with primary and metastatic brain tumors based on literature data. We searched eLIBRARY, PubMed databases by keywords. We concluded, that preventive antiepileptic drugs administration in patients with primary or metastatic brain lesions does not lower the risk of acute symptomatic postoperative seizures or epilepsy incidence, and therefore should not be recommended. Experts’ opinion states that in patients with brain tumors even one unprovoked seizure makes it feasible to initiate antiepileptic drugs therapy as soon as possible. In case of two or more unprovoked episodes (with over 24 hours difference) the diagnosis of “epilepsy” is legitimate and antiepileptic therapy should be started. The treating physician’s choice of antiepileptic therapy is based on type of seizures, age and sex of the patient, the comorbidity and potential antiepileptic drugs pharmacokinetic interactions with other drugs (including chemotherapy), in particular, one should avoid the use of liver microsomal-inducing antiepileptic drugs. The presented algorithms provide the decision-making guidelines in case of intraoperative focal seizures, acute symptomatic seizures and status epilepticus occurrence in early postoperative period.
