Background: The objective of this study was to characterize chronic disease, health-related quality of life (HRQOL), emotional distress, and social attainment among long-term survivors of neuroblastoma.Methods: Chronic health conditions among 136 ≥10-year neuroblastoma survivors (median age, 31.9 years; range, 20.2-54.6 years) and 272 community controls (median age, 34.7 years; range, 18.3-59.6 years) were graded with a modified version of the Common Terminology Criteria for Adverse Events (version 4.03). HRQOL and emotional distress were assessed with the Medical Outcomes Study 36-Item Short Form Health Survey and the Brief Symptom Inventory-18. Log-binomial regression and logistic regression were used to compare the prevalence of chronic conditions and the frequency of reduced HRQOL, distress, and social attainment between survivors and controls. The cumulative burden approach was used to estimate multimorbidity.Results: By the age of 35 years, survivors had experienced, on average, 8.5 grade 1 to 5 conditions (95% confidence interval [CI], 7.6-9.3), which was higher than the average for controls (3.3; 95% CI, 2.9-3.7). Compared with controls, survivors had a higher prevalence of any pulmonary (P = .003), auditory (P < .001), gastrointestinal (P < .001), neurological (P = .003), or renal condition (P < .001); were more likely to report poor physical HRQOL (P = .01) and symptoms of anxiety (P = .01) and somatization (P = .01); and were less likely to live independently (P = .01) or marry (P = .01). In analyses limited to survivors, those with 1 or more grade 3 to 5 conditions were more likely to report reduced general health (odds ratio [OR], 6.6; 95% CI, 1.6-26.9), greater bodily pain (OR, 4.2; 95% CI, 1.0-17.0), and unemployment (OR, 3.2; 95% CI, 1.2-8.5).Conclusions: Because of the high burden of chronic diseases and the associations of these morbidities with reduced HRQOL and social attainment, screening and interventions that provide opportunities to optimize health are important among neuroblastoma survivors.
