Objectives: Neuroblastoma is a common childhood malignancy with limited number of publications from the middle east. This study describes the clinical characteristics and the survival outcome of Omani children with neuroblastoma who are treated at the National Oncology Center from 2010 to 2017. Methods: Data was retrospectively collected for Omani Children aged less than thirteen-years with neuroblastoma from January 2010 to December 2017. The survival data were statistically correlated with known prognostic factors including age, stage of disease, MYCN profile and presence of metastasis. Results: Fifty-six Omani children were included. The male to female ratio was 1:1. The mean age at presentation was one year and ten months. The two most common presenting complaints were body masses (48.2%) and constitutional symptoms (33.9%). About 54.5% were high-risk, 35.7% were intermediate risk and 9.8% were low-risk. High-risk neuroblastoma was mainly in children older than one year (76.6%), with low-risk being mainly observed in less than one year of age (80%). The overall survival of all groups combined was 74% (p value < 0.05); and the event free survival was 67% (p value < 0.05). The five years overall survival for the high-risk, intermediate-risk and low-risk was 60%, 88% and 100% respectively. Moreover, the event free survival was 51%, 79% and 100% respectively. Conclusion: Omani children with neuroblastoma mainly presented with masses or constitutional symptoms. The majority of Omani children with neuroblastoma had an advanced disease at presentation which was associated with inferior survival. The survival outcomes were reasonably similar to published international data.
