The growing prevalence of childhood cancer survivors in Australia.

Survivors of childhood cancer have an increased risk of long-term health issues arising mostly from the side effects of treatment. Using population-based data from the Australian Childhood Cancer Registry (ACCR) for children aged 0-14 at diagnosis between 1983 and 2018, there were a total of 17,468 prevalent cases of childhood cancer survivors on 31 December 2018. We also found an 80% increase in the number of 5-year prevalent cases, from 1979 in 1988 to 3566 in 2018. Both short- and long-term prevalence estimates are important for monitoring childhood cancer survivorship and planning for the specific needs of this expanding cohort.
