Approximately 300 to 400 pediatric brain stem tumors are diagnosed each year in the United States. Diffuse intrinsic pontine glioma (or DIPG) accounts for approximately 75% to 80% of pediatric brain stem tumors. Most children with DIPG are diagnosed between the ages of 5 and 10 years. The median survival for children with DIPGs is less than 1 year, although about 10% of children will survive longer than 2 years. Approximately 4% of children with DIPGs are diagnosed when younger than 3 years. The prognosis of these children is more favorable than that of older children, with 28% of younger children alive at 2 years compared with 8% of children aged 3 to 10 years at diagnosis and 14% of children older than 10 years at diagnosis. With more research about this deadly disease, doctors will be able to recognize DIPG earlier and research better ways to fight it.
