Relationship between minimal residual disease and outcome in adult acute lymphoblastic leukemia.


In children with acute lymphoblastic leukemia (ALL), the level of minimal residual disease (MRD) at the end of induction strongly predicts outcome, presumably because it measures both drug sensitivity and the number of leukemic cells requiring elimination. Children with high levels (> 10(-3) leukemic cells per marrow cell) nearly always relapse, whereas… (More)
