Abstract: | The role of antiepileptic drugs (AED) prophylaxis in primary brain tumor (PBT) seizure-na < ve patients remains unclear. Additionally, AED are associated with severe side effects, negative impact on cognition and drug interactions. Little is known about current practice regarding prophylactic AED use in PBT. We investigated its use in a tertiary care cancer center. We reviewed medical records of 260 patients registered in our center between 2008 and 2012, focusing on prophylactic AED use. A descriptive analysis was performed with SPSS IBM version 20.0. Median age was 44.5 years (11-83). Most patients had ECOG PS a parts per thousand currency sign1 (76.4 %). Among 141 seizure-na < ve patients, 70.2 % received an AED as primary prophylaxis (PP). Most commonly used drugs as PP were phenytoin (85.9 %), carbamazepine (6.1 %) and phenobarbital (5.1 %). In only 14 patients (14.1 %) AEDs were eventually discontinued, in a median time of 5.9 months (1.1-76.8 m). AED were used as PP in 60 % of low-grade gliomas, 73.3 % of anaplastic gliomas and 93.9 % of glioblastoma patients. Twenty-seven patients (27.3 %) on PP presented seizures, generally associated with tumor progression. Of the 42 seizure-na < ve patients not receiving AED prophylaxis, only two presented seizures, which occurred during or within the first week post-radiotherapy. In this cross-sectional study, prophylactic AED use in PBT was extremely high. Postoperatively, AED were discontinued in a minority of patients, mostly after a prolonged period. Current prophylactic AED use patterns in PBT are not in accordance with established guidelines. |
