Popis: Summary Children and adolescents presenting with a markedly elevated white blood cell (ME WBC) count (WBC ≥200 × 109/l) comprise a unique subset of high-risk patients with acute lymphoblastic leukaemia (ALL). We evaluated the outcomes of the 251 patients (12% of the study population) with ME WBC treated on the Children's Cancer Group-1961 protocol. Patients were evaluated for early response to treatment by bone marrow morphology; those with a rapid early response were randomized to treatment regimens testing longer and stronger post-induction therapy. We found that ME WBC patients have a poorer outcome compared to those patients presenting with a WBC
