Oligoastrocytoma

Tumors that affect the glial cells in the central nervous system are known as "gliomas." An oligoastrocytoma is a type of mixed glioma that affects the oligodendrocytes and astrocytes, two different types of glial cells. Like other tumors, oligoastrocytomas are graded on a scale from 1 to 4, with grades 1 and 2 describing low-grade tumors and grades 3 and 4 describing anaplastic oligoastrocytomas, which are more aggressive, malignant tumors.

Oligoastrocytomas most often develop in the cerebrum. As a tumor grows and puts pressure on the brain, it can cause headaches, seizures, personality changes and other symptoms. A physician may order imaging tests and a biopsy to diagnose an oligoastrocytoma and determine the best course of treatment.

Our Approach

Moffitt Cancer Center takes an individualized approach to diagnosing and treating oligoastrocytomas. We recognize that no two cancer cases are the same, which is why our cancer experts develop treatment plans that are tailored to the unique needs of each patient. Treatment may include surgery, chemotherapy, radiation therapy or biological therapies to remove or destroy cancer cells. The treatment option that is right for you will depend on the size, location and stage of your tumor as well as your individual health, age and personal preferences. Because of the many complex factors involved in determining the best treatment for oligoastrocytoma, the multispecialty experts within Moffitt’s Neuro-Oncology Program collaborate to ensure our patients receive the best possible treatment and supportive care.

In addition to diagnosing and treating patients with all types of brain cancer, Moffitt Cancer Center is dedicated to advancing our knowledge of cancer and discovering the most effective methods for treating brain cancer. As such, Moffitt is an active member of the National Cancer Institute’s Adult Brain Tumor Consortium and runs a robust clinical trials program. Patients who choose to participate in a clinical trial may receive advanced treatment options that have not yet been made widely available.
