[Treatment of malignant gliomas by selective intraarterial infusion chemotherapy with high-dose ACNU and autologous bone marrow transplantation--preliminary report].
Six patients with malignant gliomas were treated by selective intracarotid infusion of ACNU at 15 mg/kg (about 600 mg per m2) or 10 mg/kg with or without radiotherapy and rescue of autologous bone marrow transplantation after surgery. These high doses of ACNU were well tolerated if bone marrow rescue was performed and granulocyte colony stimulating factor was used. With the development of microcatheters for use in selective intraarterial infusion, it has become possible to cannulate the major artery and infuse drugs at high dose into the artery feeding the tumor. The complication of ocular toxicity can be avoided by using the Tracker-18 or Balt (Magic) angiographic catheter. On the other hand, drug dosage and infusion rate must be chosen carefully, because of the increased likelihood of local arteritis and local necrosis caused by high dosage of ACNU. In the present study, local arteritis or cerebral infarction in the area of the middle cerebral artery was considered to have been prevented by extending the infusion time to 80 minutes. When combined with radiotherapy, 10 mg/kg of ACNU and 80 min. of infusion time were found to be optimal in relation to brain tolerance.
