What Is Glioma?

Take Action

Types of Gliomas

Symptoms of the glioma will depend on which of the glial cell and the corresponding type of tumor. Many brain tumor symptoms include headaches, seizures, nausea or vomiting, lethargy and possibly behavioral changes.

Astrocytoma: Astrocyte cells are part of the underpinnings that regulate neural functioning. Astrocytomas can range from benign, grade 1 tumors to the very aggressively malignant grade 4 or glioblastoma multiforme tumor.

Ependymoma: Ependymal cells coat the center of the spinal cord and the ventricles of the brain. Symptoms correspond to the area of the brain that the tumor is affecting (the fluid-filled ventricles) and may include: larger head size in babies, headache, nausea and vomiting.

Mixed Glioma (also called Oligoastrocytoma): This type of tumor is a combination of oligodendrocyte and astrocyte malignant cells. Symptoms include headache, nausea and vision difficulties. Surgery, usually followed by radiation and sometimes chemotherapy, is recommended. Astrocytes generally grow faster than oligodendrocytes, so that part of the tumor may determine the course of the treatment.

Oligodendroglioma: Oligodendrocytes help form the myelin sheath around nerves in the brain and spinal cord. Generally, oligodendroglioma is a slow-growing tumor.

Optic Glioma: Most often found in children, especially those with neurofibromatosis. Often presents with vision problems due to its location along the optic pathway. If it is very slow-growing, close observation may be enough. Otherwise standard surgery, radiation and chemotherapy are used.

Gliomatosis Cerebri: It is diffuse (scattered) and widespread, symptoms can include headaches, seizures, memory issues and personality changes. Radiation and chemotherapy are the recommended course of action because the tumors are too widespread for surgery.

How Are Gliomas Diagnosed?

Gliomas are most often diagnosed using magnetic resonance imaging (MRI) of the brain. A biopsy can identify the size of the tumor, the grade of the tumor and the type of cells it’s made of.

State-of-the-Art Treatments for Gliomas at NSPC

Depending on the the type of cell forming the tumor, the irregularly shaped cells can be tentacle-like in their growth into healthy tissue, making surgical resection (removal) difficult.

NSPC Brain & Spine Surgery (NSPC) (NSPC) has a seasoned multi-disciplinary team including radiation oncologists, neurosurgeons, neuro-oncologists and anesthesiologists to give you the best brain tumor treatment options. NSPC participates in clinical trials, so you have access to the most up-to-date available treatments and experimental innovations.

Using functional MRI scans, neurosurgeons can identify the association between the tumor and the nearby brain tissue using intraoperative brain mapping, allowing the physician to note the functional areas that the tumor is touching. The computerized images—along with other MRIs and medical scans—assist your neurosurgeon in navigating the brain during surgery.

Surgery followed by radiation and sometimes chemotherapy is the usually recommended course of treatment.

Stereotactic radiosurgery is used to treat gliomas. Pinpointed radiation beams focus on the tumor, often only needing 1 to 5 sessions. The procedure is bloodless, and patients usually go home the same afternoon.
