Background: Data from EUROCARE have consistently shown lower survival for adolescents and young adults (AYAs; aged 15-24 years) than for children (0-14 years) for most cancers that affect both groups, and modest survival improvements up to 2000-02. AYAs have longer survival than that of adults for most cancers. We used the latest definition of AYAs (aged 15-39 years) and provided estimates of 5-year relative survival for European AYAs with cancer diagnosed in 2000-07, compared with children and adults (40-69 years) with cancer, and assessed survival improvements over time. Methods: We analysed data from population-based cancer registries of 27 European countries participating in EUROCARE-5. We used the so-called complete method to estimate 5-year, population-weighted relative survival for 19 cancers affecting AYAs and children, and for 27 cancers affecting AYAs and adults. We assessed relative-survival differences between children versus AYAs, and between AYAs versus adults, using the Z test. We used the period approach to estimate 5-year relative survival over time for children and AYAs, and used a generalised linear model to model survival time trends (1999-2007) and to assess the significance of changes over time. Findings: We analysed 56 505 cancer diagnoses in children, 312 483 in AYAs, and 3 567 383 in adults. For all cancers combined, survival improved over time for AYAs (from 79% [95% CI 78·1-80·5] in 1999-2002 to 82% [81·1-83·3] in 2005-07; p
