What is Oligodendroglioma?
Oligodendroglioma is a form of brain tumor that is suspected to originate from the oligodendrocytes in the brain or from the glial precursor cells.
This brain tumor is most common in adults above the age of 35 years but is seen in children in rare cases as well.
Although scientists have not been able to identify the exact cause for development of this tumor in the brain, certain viruses have been linked to its occurrence.
What are the signs and symptoms of Oligodendroglioma?
One of the most common symptoms of Oligodendroglioma is the beginning of seizure activity. This occurs mostly in the frontal lobe. It is signified by constant headaches combined with increasing inter-cranial pressure.
According to the location of the tumor in the brain, the patient might also experience loss in vision, cognitive disability and motor weakness.
How is Oligodendroglioma diagnosed?
The main diagnostic test for Oligodendroglioma includes imaging tests, such as magnetic resonance imaging (MRI), computerized tomography (CT) scan, etc, that allow the doctor to view the size, location and other details of the brain tumor.
However, the final diagnostic test will usually entail a biopsy on a sample of the tumor to determine its cause, origin, cellular character, etc.
How is Oligodendroglioma staged?
The Oligodendroglioma brain tumor is globally staged as:
- Grade II – Low grade
- Grade III – High grade
How is Oligodendroglioma treated?
The treatment method for an Oligodendroglioma in the brain is basically the surgical removal of maximum portion possible from the tumor. This helps to collect sample for a detailed biopsy as well as its removal.
These are the types of treatment commonly used to remove the Oligodendroglioma:
Grade II Oligodendroglioma – in case such an Oligodendroglioma has been removed using surgical methods, the doctor will usually recommend follow-up test including regular MRI scans. In case the surgery was not able to fully remove the brain tumor due to inaccessible location, radiation therapy is used to destroy the remaining cancer cells.
Grade III Oligodendroglioma – This type of brain tumor is typically treated with a combined treatment method using radiation therapy and chemotherapy. In case, the brain tumor is recurrent in character, then the doctor might also use surgery and chemotherapy to arrest and remove the brain tumor entirely.
Oligodendroglioma are most commonly seen occurring in adults and immediate and prompt diagnosis with correct treatment can make a large difference in the rate of success as well as rehabilitation to normal life after the treatment at a faster pace.
