Observed 5-year survival in Ireland (79% overall) was slightly higher than European and US averages, and was significantly higher for acute non-lymphocytic leukaemia (67%) and (compared with the USA) significantly lower for Hodgkin lymphoma (83%). No significant increases in incidence rates were evident from the available 7 years’ data, either overall or for particular diagnostic groups. Rates of childhood cancer mortality have declined markedly since the 1950s.Conclusions: Data presented here are in line with other developed countries and suggest major improvements in treatment and consequent survival.
