Issues raised by the incidence and survival of childhood cancers
An Article by Audrey Bonaventure and colleagues in the Lancet Haematology provides international comparisons of 5-year net survival statistics of children diagnosed with leukaemia, and another Article by Eva Steliarova-Foucher and colleagues in the Lancet Oncology is an exhaustive report on worldwide incidence rates of childhood cancers observed in 2001–10. Both are based on best-quality data from population-based cancer registries. The first Article by Bonaventure and colleagues1 documents the steady improvements in survival in children with leukaemia from 1995–2009.
