✓ The rationale for, methodology of, and experience with intra-arterial BCNU infusion therapy of malignant glioma are described. This approach achieves tumor levels of drug four times greater than equal doses infused intravenously, and has been used to treat 79 patients over the course of 4 years. The drug was given in 192 infraophthalmic and 66 supraophthalmic carotid artery infusions. Patients who were treated via infraophthalmic carotid artery infusion following tumor recurrence (after both operation and irradiation) survived 54 additional weeks (92 weeks after initial diagnosis). Patients who were treated with BCNU immediately after initial irradiation therapy survived 64 weeks (infraophthalmic carotid artery infusion) and 49.5 weeks (supraophthalmic carotid artery infusion). The major ocular complications (pain and diminished visual acuity) associated with infraophthalmic carotid artery infusion are avoided by selective balloon-guided supraophthalmic carotid artery administration. However, both approaches were associated with white-matter changes, seen as diminished absorption on computerized tomography scans, in 20% of patients treated following irradiation therapy. This toxicity appears to preclude intra-arterial BCNU treatment in the immediate postirradiation period. Better results are being achieved with our current therapy, which involves four infusions of BCNU (400 mg every 4 weeks) into the infraophthalmic or supraophthalmic carotid artery in advance of irradiation. Cisplatin infusions (60 to 90 mg/sq m every 5 weeks) are offered for recurrent glioblastoma.
