Doctors are working to learn more about astrocytoma. This includes ways to prevent it and how to provide the best care to children diagnosed with this disease. The following areas of research may include new options for patients through clinical trials. Always talk with your child’s doctor about the diagnostic and treatment options best for your child. 

  • Improved methods of imaging and surgery. Imaging techniques are being developed and improved that help surgeons better pinpoint the tumor’s location. These techniques can help reduce or prevent damage to the healthy parts of the CNS during treatment.

    • Functional MRI (fMRI) identifies the parts of the brain that control speech, hearing, vision, touch, and movement. The specific locations of these functions are slightly different in every person. Functional MRI allows surgeons to plan surgery around these areas.

    • Image-guided stereotaxis allows surgeons to visualize and operate on the brain using 3-dimensional outlines of the brain and the tumor. Along with specialized software, these images help guide the surgeon to the tumor. Tumors that were once considered inoperable often can be removed with this technique.

  • Improved ways to give radiation therapy. Conformal radiation therapy is a way to deliver high doses of radiation directly to a tumor and not healthy tissue. This technique produces detailed 3-dimensional maps of the brain and tumor. These maps help doctors know exactly where to direct the radiation treatment.

  • Molecular testing of the tumor. Your doctor may recommend running laboratory tests on a tumor sample to identify specific genes, proteins, and other factors unique to the tumor. Results of these tests will help decide whether your treatment options include a type of treatment called targeted therapy (see below). Recently, researchers have found genetic changes that are common in low-grade astrocytomas. Researchers are particularly interested in changes on a gene called BRAF.

    Researchers have also discovered specific patterns of genetic changes in high-grade astrocytomas. But treatments targeting these changes are not yet being studied in clinical trials.

  • Targeted therapy. Targeted therapy is a treatment that targets the tumor’s specific genes, proteins, or the tissue environment that contributes to growth and survival. This type of treatment blocks the growth and spread of tumor cells while limiting damage to healthy cells. Specifically, researchers are studying new drugs that target changes on the BRAF gene as a treatment for children with recurrent astrocytoma.

  • Immunotherapy. Immunotherapy, also called biologic therapy, is designed to boost the body’s natural defenses to fight the tumor. It uses materials made either by the body or in a laboratory to improve, target, or restore immune system function. Researchers are studying how well these drugs work and how safe they are for children with high-grade and low-grade astrocytoma.

  • Palliative care. Clinical trials are underway to find better ways of reducing symptoms and side effects of current astrocytoma treatments to improve patients’ comfort and quality of life.
