title: Evaluation of cyclocytidine in children with advanced acute leukemia and solid tumors.
abstract: Cyclocytidine, a slow-release form of cytosine arabinoside, was evaluated in 69 children with advanced acute leukemia and solid tumors. One child with acute lymphocytic leukemia attained a complete remission. This child had received intrathecal cytosine arabinoside prior to the cyclocytidine. Eighteen of the 31 patients with acute lymphocytic leukemia/acute undifferentiated leukemia who did not respond received two or more courses of the drug. There were no responses in 15 children with acute myelogenous leukemia, in 11 children with neuroblastoma, or in 11 children with various solid tumors of childhood. A dose of 600 ng/m2/day for 10 consecutive days is tolerated in children.
