title: [Two cases of central nervous system leukemia which responded excellently to intra-arterial injection of ACNU].
abstract: Local chemotherapy by intra-arterial administration of ACNU was performed in 2 cases with CNS leukemia, which responded well to this therapy. The first patient was a 42-year-old male who was diagnosed as having chronic myelogenous leukemia with local infiltration of leukemic cells to the optic nerves. By intra-arterial infusion of ACNU (60mg), symptoms and results of ophthalomological examinations were improved remarkably. The second case was a 16-year-old male diagnosed as having acute lymphoblastic leukemia, and complicating with meningeal involvement during the course of chemotherapy. Complete remission was achieved by intra-thecal administration ACNU. Intra-arterial infusion of ACNU would be an effective local chemotherapy of CNS leukemia and its effectiveness could be achieved by less dose of ACNU compared to that of intravenous infusion. Therefore, side effects, e.g., delayed myelosuppression caused by ACNU could be decreased by this method.
