title: Incidence and survival analyses in children with solid tumours diagnosed in Sweden between 1983 and 2007.
abstract: OBJECTIVE
  Solid tumours constitute 40% of childhood malignancies. The Swedish Childhood Cancer Registry is population based and includes all children with cancer reported from the six paediatric oncology centres in Sweden. The aim was to investigate incidence and survival.
  
  
  METHODS
  We used the new WHO ICCC-3 for reclassification of the patients. Incidence and survival analyses were performed in the study population.
  
  
  RESULTS
  Two thousand four hundred and eighty-seven children (<15 years) were diagnosed with solid tumours in Sweden between 1983 and 2007. The distribution of diagnoses was similar to that reported in other studies. The annual incidence was 65.3 per million children. The survival rates at 10 years of follow-up have improved significantly when comparing the two time periods, 1983-1995 and 1995-2007 (76 vs. 82%; p < 0.01).
  
  
  CONCLUSIONS
  The mean annual incidence of solid tumours in children was 65.3/million and has been stable during the study period. Survival rates for solid tumours at 5, 10 and 20 years follow-up were 80, 79 and 76%, respectively.
