D. Ruano et al., Molecular and clinical prognostic factors in BFM-treated childhood acute lymphoblastic leukemia patients: a single institution series, HAEMATOLOG, 85(8), 2000, pp. 877-878
We analyzed the impact on outcome of minimal residual disease (MRD) and cli
nical factors in 97 children with acute lymphoblastic leukemia. Unfavorable
factors were early-B and -T immunophenotype, hyperleukocytosis, non-respon
se to steroids, detection of MRD at the end of induction therapy. A level o
f MRD greater than or equal to 1/10(3) leads to a lower probability of dise
ase-free survival.
