Glioma Astrocytomas

Definition

Childhood astrocytomas are brain tumors that begin in star-shaped brain cells called astrocytes. These tumors are a type of glioma and can occur in various parts of the brain and spinal cord. They are the most common brain tumors in children.

Characteristics

Astrocytomas vary in behavior. Low-grade astrocytomas grow slowly and are less likely to spread, while high-grade (such as anaplastic astrocytoma) are more aggressive. Symptoms depend on the tumor’s location and may include headaches, nausea, vision or balance problems, and behavioral changes.

Diagnosis and Prognosis

Diagnosis involves neurological exams, brain imaging (MRI), and often biopsy. Prognosis depends on tumor grade, size, location, and how much of the tumor can be surgically removed. Low-grade astrocytomas generally have excellent outcomes, while high-grade types are more challenging.

Treatment

Treatment may include surgery, especially for low-grade tumors. Radiation therapy and chemotherapy are used when surgery is not possible or for more aggressive tumors. Long-term monitoring is important to detect recurrence or treatment-related effects.
