Abstract
Purpose EUROCARE collected data from population-based cancer registries in 20 European countries. We used this data to compare childhood cancer survival time trends in Europe. Patients and Methods Survival in 44,129 children diagnosed under the age of 15 years during 1983 to 1994 was analyzed. Sex- and age-adjusted 5-year survival trends for 10 common cancers and for all cancers combined were estimated for five regions (West Germany, the United Kingdom, Eastern Europe, Nordic countries, and West and South Europe) and Europe as a whole. Europe-wide trends for 14 rare cancers were estimated. Results For all cancers combined, 5-year survival increased from 65% for diagnoses in 1983 to 1985 to 75% in 1992 to 1994. Survival improved for all individual cancers except melanoma, osteosarcoma, and thyroid carcinoma; although for retinoblastoma, chondrosarcoma, and fibrosarcoma, improvements were not significant. The most marked improvements (50% to 66%) occurred in Eastern Europe. For common cancers, the greatest improvements were for leukemia and lymphomas, with risk of dying reducing significantly by 5% to 6% per year. Survival for CNS tumors improved significantly from 57% to 65%, with risk reducing by 3% per year. Risk reduced by 4% per year for neuroblastoma and 3% per year for Wilms’ tumor and rhabdomyosarcoma. The survival gap between regions reduced over the period, particularly for acute nonlymphocytic leukemia, CNS tumors, and rhabdomyosarcoma. For rare Burkitt’s lymphoma, hepatoblastoma, gonadal germ cell tumors, and nasopharyngeal carcinoma, risk reductions were at least 10% per year. Conclusion These gratifying improvements in survival can often be plausibly related to advances in treatment. The prevalence of European adults with a history of childhood cancer will inevitably increase.
