Abstract: Cerebrovascular events (CVEs) are serious late adverse events among childhood cancer survivors. We estimated the incidence and risk factors of symptomatic CVEs and described the clinical characteristics among childhood cancer survivors after upper body radiotherapy. The Dutch Childhood Cancer Survivor Study LATER cohort study includes 5-year childhood cancer survivors diagnosed 50 Gy was associated with 6-fold increased risk, compared to upper body radiotherapy not involving the cranium (hazard ratio = 6.3, 95%CI: 3.3-12.1). In a subgroup with available data on lifestyle and comorbidities, hypertension (odds ratio[OR] = 6.2, 95%CI: 1.6-23.8) and obesity (BMI≥30 vs. <30 = 2.95, 95%CI: 1.1-8.0) significantly increased CVE risk. During CVE episode, 17 (16%) had a life-threatening situation, and two (2%) others died. In 28%, a second CVE developed during follow-up. At end of follow-up, 29% were deceased, and 40% of those alive were unable to carry out normal activities/active work. Childhood cancer survivors treated with higher doses of cranial radiotherapy are at highest risk for developing CVEs. CVEs occur at a young age and cause a high morbidity. Studies to investigate risk-reducing secondary preventive interventions are warranted.
