Pediatric hepatic cancer incidence and survival: 30-year trends in Ontario, Canada; the United States; and Australia.

The incidence of hepatic cancer in children appears to have increased over the last 30 years in Australia and North America. Survival differences between Australia; Ontario, Canada; and the United States observed in the 1980s and 1990s were no longer apparent and only marginal geographical differences in the hazard of mortality were observed.
