Osteonecrosis in paediatric acute lymphoblastic leukaemia: Incidence, risk factors, radiological patterns and evolution in a single-centre cohort.

ABSTRACT: Osteonecrosis (ON) is a well-known sequela of paediatric acute lymphoblastic leukaemia (ALL) treatment. Incidence differs substantially among studies and the clinical significance of radiological findings is not fully established. We analysed 256 consecutive patients with ALL treated in our Institution between October 2010 and December 2016. Within the cohort, 41 developed ON, with a mean 5-year cumulative incidence of 18.5 (standard error, SE, 5.7)% overall. The mean (SE) 5-year cumulative incidence of ON was 12.7 (2.1)% after censoring upon stem cell transplantation (SCT) and/or relapse. Patients aged ≥10 years and patients allocated to the high-risk stratum had a 10-fold and fivefold higher risk of ON respectively. The risk of ON was more than double in relapsed patients, whereas no sig
