Aim: 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: 2 487 children (< 15 years) were diagnosed with solid tumours in Sweden 1983 - 2007. The distribution of diagnoses was similar to that reported in other studies. The annual incidence was 65.3/million children. The survival rates at 10 years follow up have improved significantly when comparing the two time periods 1983-95 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.
