Changes to This Summary (01/28/2016)

The PDQ cancer information summaries are reviewed regularly and updated as new information becomes available. This section describes the latest changes made to this summary as of the date above.
Added text to state that outcomes for children with acute megakaryocytic leukemia (AMKL) vary between reported cooperative group trials, including the impact of t(1;22) on outcome. Also revised text to state that some studies have suggested that within the context of intensive chemotherapy and adequate supportive care, infants with t(1;22) can have a relatively favorable outcome that is superior to that of children with AMKL whose leukemia lacks t(1;22), with only 3 of 16 children with t(1;22) relapsing in two series; however, other studies have found the opposite in regard to outcome (cited Schweitzer et al. as reference 114).
Revised text about the CBFA2T3-GLIS2 fusion, including the incidence and outcome in acute myeloid leukemia (AML) patients.
Added Schweitzer et al. as reference 40.
Added Locatelli et al. as reference 30.
This section was extensively revised.
Added text to state that in an Italian study of 47 pediatric chronic-phase CML patients treated with 340 mg/m2 per day of imatinib, complete cytogenetic response was achieved in 91.5% of patients at a median time of 6 months, and the rate of major molecular response at 12 months was 66.6%. Thus, it appears that starting with the higher dose of 340 mg/m2 has superior efficacy and is typically tolerable, with dose adjustment as needed for toxicity (cited Giona et al. as reference 29).
Revised text to state that the question of whether a pediatric patient with CML should receive an allogeneic transplant when multiple tyrosine kinase inhibitors are available remains unanswered; however, recent reports suggest that progression-free survival does not improve when utilizing hematopoietic stem cell transplantation, compared with the sustained use of imatinib.
This summary is written and maintained by the PDQ Pediatric Treatment Editorial Board, which is editorially independent of NCI. The summary reflects an independent review of the literature and does not represent a policy statement of NCI or NIH.
