An astrocytoma is a brain tumor that originates from star-shaped cells called astrocytes. Astrocytes are a kind of glial cell, cells that support and nourish neurons in the brain. Like other kinds of gliomas (tumors that arise from glial cells), astrocytomas are divided into four grades, depending on their cells' appearance under a microscope; the higher a tumor's grade number, the more severe it is. Grades 1 and 2 are considered low-grade astrocytomas, and grades 3 and 4 are considered high-grade astrocytomas.
Most astrocytomas are both highly treatable and highly curable. The most common kind of astrocytoma, called a pilocytic astrocytoma, has a cure rate over 90 percent.
Children and adolescents with astrocytomas are treated at Dana-Farber/Boston Children's through the Brain Tumor Center's Glioma Program, one of the largest and most experienced pediatric glioma programs in the world. Our glioma specialists — a team of neuro-oncologists, surgeons, pathologists and radiation oncologists — focus solely on the care of children diagnosed with gliomas
