Abstract Data on 849 children diagnosed with malignant hepatic tumours (International Classification of Childhood Cancer, Group VII) before the age of 15 years during 1978-1997 in Europe were extracted from the ACCIS database. Age-standardised incidence during 1988-1997 was 1.5 per million overall, 1.2 per million for hepatoblastoma and 0.2 per million for hepatic carcinoma. Over 90% of cases of hepatoblastoma occurred before age 5 years, whereas hepatic carcinoma had a fairly flat age distribution. Both tumours had an incidence in boys of 1.5-1.6 times that in girls. There were no significant time trends in incidence during 1978-1997. Five-year survival from hepatoblastoma diagnosed during 1988-1997 was 63% overall, and ranged from 52% in Eastern Europe to 84% in the North. Survival from hepatic carcinoma was much lower (37%). Between 1978-1982 and 1993-1997, 5-year survival (95% confidence interval (95% CI)) increased from 28% (95% CI 18-39) to 66% (95% CI 55-74) for hepatoblastoma and from 17% (95% CI 6-33) to 50% (95% CI 26-70) for hepatic carcinoma. These increases reflect the impact of advances in treatment of childhood liver cancer at a population level.

Abstract
Abstract Data on 849 children diagnosed with malignant hepatic tumours (International Classification of Childhood Cancer, Group VII) before the age of 15 years during 1978-1997 in Europe were extracted from the ACCIS database. Age-standardised incidence during 1988-1997 was 1.5 per million overall, 1.2 per million for hepatoblastoma and 0.2 per million for hepatic carcinoma. Over 90% of cases of hepatoblastoma occurred before age 5 years, whereas hepatic carcinoma had a fairly flat age distribution. Both tumours had an incidence in boys of 1.5-1.6 times that in girls. There were no significant time trends in incidence during 1978-1997. Five-year survival from hepatoblastoma diagnosed during 1988-1997 was 63% overall, and ranged from 52% in Eastern Europe to 84% in the North. Survival from hepatic carcinoma was much lower (37%). Between 1978-1982 and 1993-1997, 5-year survival (95% confidence interval (95% CI)) increased from 28% (95% CI 18-39) to 66% (95% CI 55-74) for hepatoblastoma and from 17% (95% CI 6-33) to 50% (95% CI 26-70) for hepatic carcinoma. These increases reflect the impact of advances in treatment of childhood liver cancer at a population level.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
