Abstract Background Although paediatric astrocytoma has an excellent 5-year survival rate, survivors remain at risk for morbidity and late mortality. This study aimed to estimate the risk of late mortality, chronic conditions, poor health status and social impairment in ageing paediatric astrocytoma survivors. Methods We longitudinally evaluated 1182 5-year astrocytoma survivors diagnosed between 1970 and 1986 and 4023 siblings enrolled in a retrospective cohort study. Kaplan–Meier estimates of late mortality and cumulative incidence of serious chronic conditions were estimated. Cox regression models provided hazard ratios (HRs) with 95% confidence intervals (CIs) for development of chronic conditions, and generalised linear models provided relative risks (RRs) of the poor health status and social outcomes. Results At 30 years from diagnosis, cumulative late mortality was 22.1% (CI 20.0–24.3%), primarily due to disease progression or recurrence. Compared with siblings, survivors were at increased risk of serious chronic conditions (HR 4.6, CI 3.8–5.5). Survivors reported higher rates of poor general health (RR 3.3, CI 2.8–3.8), poor mental health (RR 1.9, CI 1.7–2.1), functional impairment (RR 9.0, CI 7.7–10.5) and activity limitation (RR 3.6, CI 3.1–4.2) and lower rates of college graduation (RR 0.75, CI 0.69–0.82), marriage (RR 0.62, CI 0.58–0.66), employment (RR 0.75, CI 0.72–0.79) and household income ≥$40,000 (RR 0.68, CI 0.64–0.73). Even survivors without radiation exposure had elevated risk of chronic conditions, poor health status and social impairment compared with siblings. Conclusions Survivors of paediatric astrocytoma are at high risk for long-term complications of their disease and its treatment. They require lifelong monitoring for late effects. Highlights • At 30 years after diagnosis of astrocytoma, cumulative late mortality was 22.1%. • By 30 years after diagnosis, 56.7% of survivors had a serious chronic condition. • Survivors reported more functional impairment and activity limitations than siblings. • Survivors were less likely than siblings to be college educated, working or married. • Survivors treated without radiation had increased medical and psychosocial conditions.
