title: Chemotherapeutic effects of intra-arterial administration of ACNU in primary intracerebral non-Hodgkin's lymphoma.
abstract: The authors report five patients with primary intracerebral non-Hodgkin's lymphoma who were treated with several cycles of intra-arterial injection of 1-(4-amino-2-methyl-5-pyrimidinyl)-methyl-3-(2-chloroethyl)-3-nitrosourea hydrochloride (ACNU) at doses of 80 to 100 mg/m2/injection at several monthly intervals. There was no simultaneous use of steroids, and no patients had concomitant immunosuppression; no patient was human immunodeficiency virus positive. This therapy was initially used in four patients with advanced recurrent lymphoma. These patients experienced tumor progression despite our institutional standard therapy comprising cranial irradiation followed by repeated courses of systemic multi-agent chemotherapy (cyclophosphamide, vincristine, adriamycin, and prednisolone) more than 3 months previously. Based upon brain computed tomography scans and clinical neurologic examinations, three of the four cases showed partial responses ranging from 10 to 12 months in duration, whereas the other patient remained stable without worsening for 8 months. A fifth case was particularly noteworthy; this patient had no prior therapy and intra-arterial chemotherapy alone induced an 18-month, disease-free remission. No significant therapy-related complications nor neurotoxicity were seen. These results suggest that intra-arterial administration of ACNU may be a potential candidate for intracerebral lymphoma therapy.
