Prognosis for children with acute lymphoblastic leukemia (ALL) has considerably improved, yet relapse still occurs in a significant proportion of patients. Conceivably, the most immature leukemia cells may be more resistant to therapy and initiate relapse. We studied 42 patients with childhood ALL treated according to the ALL-BFM 2000 protocol. At diagnosis, we determined the characteristic immunophenotype of the leukemic cells by flow cytometry and also investigated the expression of CD34 and CD38...
