Sixteen pediatric patients with brainstem glioma were treated with a combination of interferon-β,1-(4-amino-2-methyl-5-pyrimidinyl)-methyl-3-(2-chloroethyl)-3-nitrosourea hydrochloride(ACNU),and radiation therapy(LAR therapy).All patients received 1-1.5 million IU/day of interferon-β intravenously for 1 week of each 6-week cycle.In addition,ACNU(2-3mg/kg)was given on the 2nd day of each cycle.Conventional focal irradiation(1.5-2 Gy/day for 5 days to a total dosage of 40-60 Gy)was administered beginning on day 3.Patients underwent at least two 6-week cycles.Adverse effects included nausea,vomiting,and myelosuppression,but were mild and transient.Response to treatment was evaluated by the reduction in tumor size measured on postcontrast computed tomographic scans and magnetic resonance images.Responses occurred in 10 of 11 patients with the intrinsic type of brainstem glioma,including three complete and seven partial responses.Two of five patients with exophytic type gliomas partially responded.The median survival was 15.7 months,a remarkable improvement over the natural course of this disease.These results indicate that LAR therapy is a useful primary treatment for pediatric patients with brainstem gliomas.
