Childhood Astrocytoma Treatment
Treatment Options for Childhood Astrocytomas
Key Points for this Section
Childhood Low-Grade Astrocytomas
When the tumor is first diagnosed, treatment for childhood low-grade astrocytoma depends on the location of the tumor and is usually surgery. An MRI is done after surgery to see if there is tumor remaining.
If the tumor was completely removed by surgery, more treatment may not be needed and the child is closely watched to see if symptoms appear or change. This is also called watchful waiting.
If there is tumor remaining after surgery, treatment may include the following:
In some cases, children who have a visual pathway glioma will be treated by watchful waiting. In other cases, treatment may include surgery or radiation therapy. A goal of treatment is to save as much vision as possible. The effect of tumor growth on
the child's vision will be closely followed during treatment.
Children with neurofibromatosis type 1 (NF1) may not need treatment unless the tumor grows or symptoms, such as vision problems, appear.
Children with tuberous sclerosis may develop benign (not cancer) tumors in the brain called subependymal giant cell astrocytomas (SEGAs). These tumors may be treated with drugs to shrink them instead of surgery.
Recurrent Childhood Low-Grade Astrocytomas
Before more cancer treatment is given, imaging tests, biopsy, or surgery are done to be sure cancer is present and find out how much cancer there is.
Treatment of recurrent childhood low-grade astrocytoma may include the following:
- More surgery to remove the tumor.
- Radiation therapy to the tumor only, if radiation therapy was not used when the tumor was first diagnosed.
Conformal radiation therapy may be given.
- Surgery, chemotherapy, and/or radiation therapy, if the patient had only surgery when the tumor was first diagnosed.
- Chemotherapy if the tumor recurred after treatment with radiation therapy.
- Chemotherapy if the tumor recurred where it cannot be removed by surgery and the patient had radiation therapy when the tumor was first diagnosed.
- A clinical trial of a new treatment.
Childhood High-Grade Astrocytomas
Treatment of childhood high-grade astrocytoma may include the following:
Recurrent Childhood High-Grade Astrocytomas
Treatment of recurrent childhood high-grade astrocytoma may include the following:
