Background And Objectives:
Neuroblastoma, the most common extracranial solid tumor in children, is rare in adults. This study compares patient characteristics, disease patterns, and treatments among adults, adolescents, and children with neuroblastoma.
Methods:
We queried the National Cancer Database (2004-2019) for neuroblastoma cases. Patient and tumor characteristics, treatments, and 5-year overall survival (5-OS) were compared between adults (≥ 18 years), adolescents (10-17 years), and children (0-9 years). Kaplan-Meier curves and Cox regression assessed survival differences.
Results:
Among 6350 neuroblastoma patients, 256 (4.0%) were adults, 222 (3.5%) were adolescents, and 5872 (92.5%) were children. Tumors were largest in adolescents (9.7 cm), followed by adults (8.0 cm) and children (6.7 cm) (p < 0.001). Adults were less likely to have tumors in the adrenal glands (34.0% vs. children: 54.7%, adolescents: 43.2%, p < 0.001) and had lower rates of metastasis (10.9% vs. 19.3% and 19.4%, p < 0.001). Compared to children, adults received less chemotherapy, immunotherapy, and bone marrow transplants (p < 0.001). 5-OS was worse in adults (65.8%), followed by adolescents (70.4%) and children (78.2%) (p < 0.001). After adjustment, adults (aHR: 2.27; 95% CI, 1.71-3.01) and adolescents (aHR: 2.02; 95% CI, 1.54-2.64) had higher hazards of death compared to children.
Conclusions:
Adults and adolescents with neuroblastoma have distinct clinical features and lower survival than children, underscoring the need for tailored treatment approaches for older patients.
Level Of Evidence:
III.
