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.

A monoclonal antibody designated PI153/3, which reacts with neuroblastoma and fetal brain, is shown to identify also a cell surface determinant shared by pre-B and mature B cells and their corresponding leukemias including chronic lymphocytic leukemia, non-Hodgkin's lymphoma, B acute lymphoblastic leukemia, and hairy cell leukemia, but not plasmacytoma. Almost all non-T, non-B acute "lymphoid" leukemias bind PI153/3. The latter includes 71 of 74 common ALL tested, most but not all "unclassified" or "null" ALL and cases of both acute undifferentiated leukemia and Ph1 positive chronic myeloid leukemia in blast crisis with common ALL phenotypes. The antigen is absent or present at very low density on normal and leukemic T lymphocyte, myeloid and erythroid cells. The determinant appears to co-redistribute with cell surface immunoglobulin in B lymphocytes and segregates independently of other cell surface antigens associated with B cells and/or cALL including HLA-DR (Ia-like antigens) and the cALL (gp 100) antigen.
