Background Children with pediatric low‐grade gliomas (PLGG) are known to have excellent 10‐year survival rates; however the outcomes of adult survivors of PLGG are unknown. We identified patients diagnosed with PLGG diagnosed between 1973 and 2008 through the Surveillance Epidemiology and End Results (SEER) database to examine outcomes of adult survivors of PLGG. Procedure Four thousand and forty patients with either WHO grade I or II PLGG were identified and outcome data retrieved. Two analyses were performed to assess survival and risk of death from tumor. Competing risks analysis was conducted and cumulative incidence curves of death due to disease were generated. Cox proportional hazards regression was performed, with adjustment for non‐disease death. Kaplan–Meier curves for overall cancer specific survival (OS) were also generated. Results The 20‐year OS was 87% ± 0.8% and the 20‐year cumulative incidence of death due to glioma was 12% ± 0.8%. The incidence of death after transition to adulthood (age greater than 22 years) was slightly lower, with 20‐year cumulative incidence of disease death of 7% ± 1.8%. Year of diagnosis, age of diagnosis, histology, WHO grade, primary site, radiation, and degree of initial resection were prognostic in univariate analysis, while the administration of radiation was the greatest risk of death in multivariate analysis of OS (hazard ratio = 3.9). Conclusions PLGGs are associated with an excellent long‐term survival, with a low likelihood of PLGG related death in adult survivors. Treatment strategies for pediatric tumors should therefore aim for disease control during childhood and adolescence with an emphasis on minimizing long‐term treatment induced toxicities.
