- Background: A comprehensive overview of neurologic complications among survivors of central nervous system (CNS) tumors in childhood is lacking. We aimed to investigate the risk for these disorders in a large, population-based study with outcome measures from nationwide hospital registries. Methods: We identified 4858 five-year survivors with diagnoses of CNS tumor in childhood in Denmark, Iceland, Finland, and Sweden in 1943-2007, and 166658 matched population comparison subjects. Inpatient discharge diagnoses of neurologic disorders were used to calculate relative risks (RRs) and absolute excess risks (AERs). Results: A neurologic disorder was verified in 1309 survivors, while 92.4 were expected, yielding an overall RR of 14.2 (95% confidence interval [CI]: 13.3-15.1) and an AER of 20 hospitalizations per 1000 persons per year. The risks remained increased more than 20 years after diagnosis (RR: 6.3, 95% CI: 5.6-7.2; AER: 11, 9-12). The most frequent diagnoses were epilepsy (affecting 14.1% of all survivors) followed by hydrocephalus (9.5%) and paralytic syndromes (4.2%), with RRs of 28.7 (95% CI: 26.0-31.6), 243 (95% CI: 190-311), and 40.3 (95% CI: 33.1-49.2), respectively. Of these outcomes, 30%-40% were diagnosed prior to or synchronously with the CNS tumor. The survivors had highly increased RRs for infectious diseases of the CNS, disorders of cranial nerves, and degenerative diseases of the nervous system. Conclusions: Survivors of childhood CNS tumors are at markedly increased risk for neurologic disorders throughout their lives. Health care professionals must be aware of survivors who might benefit from preventive interventions and intensive follow-up.

- Background: Survivors of childhood cancer may face difficulties at school. We investigated whether childhood cancer affects attainment of upper secondary education, in a register-based cohort study from Denmark, Finland, and Sweden, where we limit bias from selection and participation.Methods: From the national cancer registers, we identified all long-term survivors of childhood cancer diagnosed aged 0–14 years in 1971–2005 (n = 7629), compared them to matched population comparisons (n = 35,411) and siblings (n = 6114), using odds ratios (OR) and 95% confidence intervals (CI).Results: Overall, 6127 survivors (80%) had attained upper secondary education by age 25, compared to 84% among comparison groups. Elevated OR for not attaining this level were mainly confined to survivors of central nervous system (CNS) tumours (ORSurv_PopComp2.05, 95%CI: 1.83–2.29). Other risk groups were survivors who had spent more time in hospital around cancer diagnosis and those who had hospital contacts in early adulthood, particularly psychiatric. Survivors of all cancer types were less likely to have attained upper secondary education without delay.Conclusions: Although survivors of childhood cancer experienced delays in their education, many had caught up by age 25. Except for survivors of CNS tumours, survivors attained upper secondary education to almost the same extent as their peers.
