摘要: Background The rate of clearance antileukemic agents differs by a factor 3 to 10 among children with acute lymphoblastic leukemia. We hypothesized that the outcome treatment would be improved if doses were individualized prevent low systemic exposure drugs in patients fast drug clearance. Methods stratified and randomly assigned 182 newly diagnosed leukemia postremission regimens included high-dose methotrexate teniposide plus cytarabine. these based on body-surface area (in conventional-therapy group) or rates three medications each patient individualized-treatment group). In group, increased rapid decreased very slow Results Patients who received had significantly fewer courses exposures below target range than did patien...
