Gliomas are called brain tumors.Oligodendroglioma -it is a neoplasm that is formed from the fat cells of the sheath of nerve cells. The main symptoms of the disease include attacks of headaches, seizures, changes in behavioral reactions, numbness of the limbs and coordination disorder.

Diagnosis requires magnetic resonance imaging and biopsy. Treatment is based on the surgical method and radiation therapy.

Reasons for education

As with most brain tumors, the cause of the mutation is unknown. Oligodendroglioma of the brainThe following generally accepted risk factors:

  1. Age. According to statistics, the probability of tumor formation increases with age.
  2. Sexual accessory. Oncological diseases of brain tissue predominantly affect men.
  3. Genetic predisposition. It has been experimentally proved that in most cases cell mutations occur in people with concomitant genetic pathologies.
  4. Previous sessions of radiotherapy.

Classification of oligodendroglioma neoplasms

This disease is divided into two classes:

  1. Low-grade tumor, which is characterized by slow and limited growth.
  2. Anaplastic oligodendroglioma, which is considered a malignant neoplasm with rapid and aggressive proliferation of tumor tissue.

Clinical picture

Patients with a slow-growing type of cerebral pathology have no symptoms for a long time. The occurrence of seizures, as a rule, serves as the initial sign of the disease. In the future, patients may complain of headache and emotional disturbances.

In the overwhelming number of cases, pathological changes are localized in such parts of the brain:

  1. Frontal lobe. Such patients have behavior disorder, general weakness and numbness of one half of the body.
  2. The temporal lobe. Patients note discoordination, impaired memory and speech.

Some symptoms are caused by increased intracranial pressure, which is clinically manifested by pain, nausea and a gradual decrease in visual acuity.

Basic methods of modern diagnostics

Oligodendroglioma, whose prognosis depends on the accuracy and timeliness of the diagnosis, includes the following stages of the examination:

  • Initial inspection:

The specialist determines the state of nervous reflexes, the posterior surface of the eyeball and consciousness.

  • Laboratory blood test:

The purpose of this study is to study the functional abilities of the liver and kidneys.

  • CT scan:

X-ray scanning of the damaged area creates a three-dimensional picture of the brain tissue. To improve the image quality, a patient may be offered to take a special contrast agent. This examination lasts about 30 minutes and is absolutely painless.

  • Magnetic resonance imaging:

This technique is based on the effect of magnetism. Before the procedure, the patient is injected intravenously with a coloring substance that allows the creation of a detailed image of the affected area of ​​the brain.

  • Biopsy:

For histological analysis, a small area of ​​the tumor must be surgically removed. The expediency of such a procedure is determined individually for each clinical case.

How to treat an oligodendroglioma?

The choice of anticancer therapy depends on the nature of tumor growth, its location and the size of the oncologic focus. The treatment plan is mainly created by a group of doctors, which includes neurosurgery, oncology and neuropathologists.


Radical intervention is the most acceptable method of treatment. The operation consists in the maximum possible removal of mutated tissues without damaging the healthy brain structures. Unfortunately, not all neoplasms are susceptible to surgical excision because of their inaccessibility.

Radiation therapy

High-energy rays have a harmful effect on cancer cells. This technique is used as an independent treatment of inoperable forms of brain oncology, and as a post-operation treatment of the brain.


Systemic use of cytotoxic drugs that destroy atypical cells is shown as an adjunct to the main treatment for relapse of glioma.


Parenteral reception of steroid hormones stimulates a decrease in the size of the pathological focus and, as a result, the patients feel better overall health.

What should I do after the deletion?

After the treatment, most cancer patients need help from a physiotherapist who makes up an individual rehabilitation plan. Restoration of the patient consists of psychological and motor adaptation.

Postoperative monitoring of patients is carried out at annual preventive examinations, the purpose of which is the timely diagnosis of relapses.

The prognosis of the disease is relatively favorable, depending on the rate of growth and location of the tumor. The most positive results of therapy are observed in the second class of gliomas lesion.

How many patients live with this diagnosis?

The average survival rate of patients under the condition of comprehensive and comprehensive treatment is about 5 years. Oligodendroglioma, which has undergone rapid removal, allows you to count on high life expectancy. So the ten-year survival rate of such people is estimated at 30-40%. For many patients, the early establishment of an oncological diagnosis is key to complete recovery. For this, doctors recommend periodically to calculate the level of cancer markers in the blood.
