Anaplastic astrocytoma



Other Names:
Grade III astrocytoma
Categories:

Anaplastic astrocytoma is a rare, cancerous (malignant) type of brain tumor that arises from star-shaped brain cells called astrocytes. These cells surround and protect nerve cells in the brain and spinal cord. An anaplastic astrocytoma usually develops slowly over time, but may develop rapidly. Signs and symptoms vary depending on the location and size of the tumor and may include headaches, drowsiness, vomiting, and changes in personality or mental status. Some affected people have seizures, vision problems, weakness of the limbs, and/or coordination problems. Anaplastic astroctyomas usually occur sporadically but can be associated with a few rare, genetic disorders. Treatment may include surgery, radiation, and/or chemotherapy.[1]

Anaplastic astrocytomas are usually not inherited. These tumors typically occur sporadically, in people with no family history of astrocytomas. In most cases, the exact cause is unknown.[1][2] Familial cases of isolated astrocytomas have been reported but are very rare.[2]

Astrocytomas can have a genetic link when they are associated with a few rare, inherited disorders. These include neurofibromatosis type I, Li-Fraumeni syndrome, Turcot syndrome, and tuberous sclerosis.[1][2] Astrosytomas occur more frequently in people with one of these disorders.[1]

Like many other cancers, it is believed that isolated astrocytomas may occur due to a combination of genetic and environmental factors. This means that a person may carry a gene (or a combination of genes) that predisposes them to developing an astrocytoma, but it may not develop unless it is "triggered" by an environmental factor.[1]

When anaplastic astrocytomas are not associated with an inherited condition, the cause typically remains unknown. In these cases, genetic testing is not available. However, genetic testing is available for the few genetic disorders that are associated with an increased risk for developing an astrocytoma. These include neurofibromatosis type ILi-Fraumeni syndromeTurcot syndrome, and tuberous sclerosis.[1][2]

The Genetic Testing Registry (GTR) provides information about the labs that offer genetic testing for these conditions. On the GTR Web site, search for a disorder to find out about the genetic tests that are available. The intended audience for the GTR is health care providers and researchers. Therefore, patients and consumers with specific questions about a genetic test should contact a health care provider or a genetics professional.

If you need medical advice, you can look for doctors or other healthcare professionals who have experience with this disease. You may find these specialists through advocacy organizations, clinical trials, or articles published in medical journals. You may also want to contact a university or tertiary medical center in your area, because these centers tend to see more complex cases and have the latest technology and treatments.

If you can’t find a specialist in your local area, try contacting national or international specialists. They may be able to refer you to someone they know through conferences or research efforts. Some specialists may be willing to consult with you or your local doctors over the phone or by email if you can't travel to them for care.

You can find more tips in our guide, How to Find a Disease Specialist. We also encourage you to explore the rest of this page to find resources that can help you find specialists.

Healthcare Resources


Research helps us better understand diseases and can lead to advances in diagnosis and treatment. This section provides resources to help you learn about medical research and ways to get involved.

Clinical Research Resources

  • ClinicalTrials.gov lists trials that are related to Anaplastic astrocytoma. Click on the link to go to ClinicalTrials.gov to read descriptions of these studies.

    Please note: Studies listed on the ClinicalTrials.gov website are listed for informational purposes only; being listed does not reflect an endorsement by GARD or the NIH. We strongly recommend that you talk with a trusted healthcare provider before choosing to participate in any clinical study.

Support and advocacy groups can help you connect with other patients and families, and they can provide valuable services. Many develop patient-centered information and are the driving force behind research for better treatments and possible cures. They can direct you to research, resources, and services. Many organizations also have experts who serve as medical advisors or provide lists of doctors/clinics. Visit the group’s website or contact them to learn about the services they offer. Inclusion on this list is not an endorsement by GARD.

Organizations Supporting this Disease


Living with a genetic or rare disease can impact the daily lives of patients and families. These resources can help families navigate various aspects of living with a rare disease.

Financial Resources


These resources provide more information about this condition or associated symptoms. The in-depth resources contain medical and scientific language that may be hard to understand. You may want to review these resources with a medical professional.

Where to Start

  • The National Cancer Institute provides the most current information on cancer for patients, health professionals, and the general public.
  • The National Organization for Rare Disorders (NORD) has a report for patients and families about this condition. NORD is a patient advocacy organization for individuals with rare diseases and the organizations that serve them.

In-Depth Information

  • Medscape Reference provides information on this topic. You may need to register to view the medical textbook, but registration is free.
  • The Monarch Initiative brings together data about this condition from humans and other species to help physicians and biomedical researchers. Monarch’s tools are designed to make it easier to compare the signs and symptoms (phenotypes) of different diseases and discover common features. This initiative is a collaboration between several academic institutions across the world and is funded by the National Institutes of Health. Visit the website to explore the biology of this condition.

  • My brother died last week from grade III anaplastic astrocytoma with some grade 4 characteristics on the biopsy. My uncle died approximately 20 years ago with anaplastic astrocytoma. Of course, I now have many concerns about a possible genetic link in the family. Both my brother and uncle were 41 at the time of death. We have many male family members. I am looking for direction and resources for a possible genetic link. Does this type of cancer mainly effect males? What should family members report to the primary care physicians? Should the family members become involved in genetic testing/counseling? See answer
