Chronic myelogenous leukemia (CML) is a rare disease in children for which pediatric evidence-based guidelines are lacking. We designed an anonymous survey for practicing pediatric oncologists and bone marrow transplantation (BMT) physicians to assess their willingness to recommend BMT for a patient with CML based on various clinical scenarios. A total of 274 physicians responded to the survey (13.4% response rate). Nearly all pediatric oncologists and BMT physicians recommended against BMT at time of diagnosis of CML in the chronic phase, with only 8.0% and 1.9% recommending BMT if a matched sibling donor (MSD) and a matched unrelated donor (MUD), respectively, was available. Similarly, after a first poor response to tyrosine kinase inhibitor (TKI) therapy or hematologic relapse, physicians continued to recommend against BMT (39.5% and 23.3% recommended BMT in patients with a matched sibling donor and matched unrelated donor, respectively). However, 81.7% and 69.8% of respondents would recommend BMT after 2 hematologic relapses on TKI therapy, if an MSD and an MUD, respectively, were available. In addition, there was great interest in developing a clinical trial evaluating the safety and efficacy of stopping TKIs in children with CML who achieve and maintain a deep molecular response, with 86.7% of respondents stating they would offer such a trial to their pediatric patients. This survey highlights the need for evidence-based, pediatric-specific guidelines for the management of children and adolescents with CML.
