Abstract
To treat children with acute lymphoblastic leukemia, the pediatric oncologist must have a basic understanding and appreciation of the clinical pharmacology of vincristine, methotrexate, 6-mercaptopurine, cytarabine (cytosine arabinoside), and corticosteroids. The treating physician should be cognizant of the inter- and intrapatient variabilities in the pharmacokinetics and clinical effects of each of the drugs. The pharmacokinetics of other cancer chemotherapy agents used in the treatment of childhood leukemia should also be known (doxorubicin, asparaginase, teniposide, and cyclophosphamide), but these agents are less commonly used or administered for a short period of the total treatment. Recent laboratory studies and clinical observations have suggested ways in which the agents could be administered more optimally. For the antimetabolites, these include limited bioavailability and the absence of a diurnal variation in oral methotrexate and 6-mercaptopurine, new antifolates with better pharmacological characteristics for oral administration, intravenous therapy with 6-mercaptopurine, and subcutaneous therapy with methotrexate. For corticosteroid therapy, dexamethasone appears to have an advantage over prednisone and prednisolone in treating leukemic cells in the central nervous system. Intrathecal chemotherapy for the prevention of meningeal leukemia is more effective if the dosage is based on the volume of the central nervous system instead of the body surface area. Exposure of systemic tissue to cytotoxic drug concentrations after intrathecal chemotherapy is substantial with methotrexate and negligible with cytarabine.
