Intra-arterial Chemotherapy of Brain Cancers – pro
The brain-blood barrier is considered to be a major obstacle for delivering chemotherapy to brin tumors and obtaining durable disease control in patients with high-grade gliomas. Intra-arterial drug injection after selective catheterization of cerebral arteries has been performed in some small clinical trials in order to achieve higher drug concentration in the tumor while minimizing systemic exposure. This approach has potentail which has not yet been demonstrated.
A recent review of studies with intra-arterial administration of nitrosoureas and platinum derivatives, as well as the principal aspects and perspectives of the new strategy of blood–brain barrier disruption with osmotic agents or bradykinin analogs demonstrated no superiority of intra-arterial chemotherapy over its intravenous counterpart . It concluded that although the incidence of serious neurotoxicity is reduced with teh intra-arterial route, the risk of acute complication still contraindicates internal carotid or vertebral artery catheterization for chemotherapy administration outside the setting of well-controlled clinical trials.
