Neuroblastoma is the most common cancer in babies and the third-most common cancer in children after leukemia and brain cancer. [5] About one in every 7,000 children is affected at some time. [2] About 90% of cases occur in children less than 5 years old, and it is rare in adults. [2] [3] Of cancer deaths in children, about 15% are due to ...
The incidence rate for meningiomas is 9.51 per 100,000 people. [10] Unlike gliomas, more than 98% of meningiomas are benign. [16] The 5-year survival rate for nonmalignant meningiomas is approximately 91%. [10] The distribution and behavior of nervous system neoplasms differ significantly between adults and children.

Survival rates for most childhood cancers have improved, with a notable improvement in acute lymphoblastic leukemia (the most common childhood cancer). Due to improved treatment, the 5-year survival rate for acute lymphoblastic leukemia has increased from less than 10% in the 1960s to about 90% during the time period 2003-2009.
The median age for the diagnosis of neuroblastoma is 22 months, being rare in adolescence and adulthood but showing poor prognosis when it does present in those age groups. The degree of differentiation of neuroblastoma is correlated to the prognosis, with a wide variety of outcomes (from tumor regression to recurrence and mortality).
The age-adjusted incidence rate is 6.4 per 100,000 per year, and the death rate is 4.3 per 100,000 per year. The lifetime risk of developing brain cancer for someone born today is 0.60%. Only around a third of those diagnosed with brain cancer survive for five years after diagnosis.
Survival rates for treated esthesioneuroblastoma are best for surgery with radiotherapy (65%), then for radiotherapy and chemotherapy (51%), just surgery (48%), surgery, radiotherapy and chemotherapy (47%) and finally just radiotherapy (37%). [14] From the literature, radiotherapy and surgery seem to boast the best outcome for patients.
The overall incidence rate of brain tumors in children is 6.2 per 100,000. [9] The distribution and behavior of nervous system neoplasms differ significantly between adults and children. Gliomas are more frequent and aggressive in adults, while certain benign tumors like pilocytic astrocytomas are more common in children.
