Oligodendroglioma Brain Tumor

the this is a form of tumor of brain that I was just diagnosed with and surgery had to have the removed

Oligodendroglioma

Definition

Oligodendrogliomas is a rare form of tumors of brain. The brain is composed from a lot of cells supporting that are called the cells of glial. Any tumor of these cells of glial is called a glioma. Oligodendrogliomas is tumors that result from themselves a type of cell of glial called oligodendrocytes. These cells are the specialized cells of the brain that produces the fatty cover of cells of nerve (myelin).

Description

Oligodendrogliomas can grow in the different parties of the brain, but they the most ordinarily are found in lob them frontal or temporal of the brain. Lob them frontal are responsible of cognitive one thought about the processes (knowing, think, the erudition, and judging). Lob them temporal are responsible of the coordination, the speech, hear, the memory, and the time conscience.

There are two types of oligodendroglioma: the well differentiated tumor, that growing comparatively slowly and in a defined form; and, the anaplastic oligodendroglioma, that growing a lot more quickly and has not a well defined form. Anaplastic oligodendrogliomas is a lot oligodendrogliomas less common than well differentiated.

More common than or the form of pure oligodendroglioma is the mixed glioma, or oligoastrocytoma. These mixed gliomas is a mixture of oligodendroglioma and astrocytoma. An astrocytoma is a tumor that results from itself the astrocytes, the specialized cells in the brain that regulates the chemical environment of the brain and of assistance to form the barrier of blood brain.

Oligodendrogliomas and mixed gliomas represents roughly 4 to 5% of all tumors of primary brain and 10% of all gliomas. A primary tumor of brain is a tumor that begins in the brain, as opposed to a secondary one (or metastatic) the brain tumor, that originates in another organ and another broadcastings (evokes metastasises) to the brain.

Demographic

Oligodendromas arrives in roughly nine in a million every people. Oligodendrogliomas can arrive in the people of any age, but most of to arrive in the adults of a some acts.

Oligodendrogliomas arrives with the frequency equals in the members of all races and of ethnic groups. Seems not of not to be there relation of oligodendrogliomas to the geographic region. For the unknown reasons, the men are affected by oligodendrogliomas in the highest numbers than the women.

Cause and symptoms

The cause, or the causes, of oligodendrogliomas are not known; nevertheless, most of the people with these tumor types have type of genetic mutation on the chromosome 1, the chromosome 19, or on the two chromosomes 1 and 19. In year beginning 2001, the investigations were continuous in an attempt to determine if these genetic factors, or these other factors, cause oligodendrogliomas. Oligodendrogliomas is not contagious.

The symptoms of oligodenrogliomas are the result of increased pressure in the liquid in the skull (the hypertension of intracranial). These symptoms include:

airsick
vomiting
irritability
headache
vision disturbances
head enlargement
seized
Oligodendrogliomas also can be accompanied of a weakness or a paralysis on the body side in facing the brain side where the tumor is localized. When the tumor is localized in one lobs frontal, the patient can test gradual changes in the mood and the personality. When it is localized in one lobs temporal, the patient can test the difficulty with the speech, hear, the coordination, and the memory.

Diagnosis

The diagnosis of oligodendrogliomas begins in the meddecin's office with a basic neurological examination. This examination implies:

the reflex ones of eye of essay, examine the movement, and the student reactions
the essay hearing with a fork of tuning or done tic tap shows it
the reflex one tries with a rubber hammer
the balance and the coordination try
the shot and the cotton ball try for the key direction
the direction of direction of the tests with the various odors
the face muscle tries (for example, smile, gather, etc.)
the movement of language and the reflex one of gag try
the head movement tries
the mental statute tries (for example, asking which this of year is, that the President is, etc.)
Abstracts thinking about the tests (for example, asking the direction of a common word, as " every cloud has a surface in money. ")
the memory tries (for example, asking to have a list of repeated objects, asking the one patient to the details of what ate for the dinner last night, etc.)
If the doctor suspects a brain tumor can be the present more diagnostic tests will be ordered. These tests are executed by a neurological specialist. The imagery tests that could be ordered include the calculated tomographie (CT) and the tests of (MRI).Other of imagery of magnetic resonance can include a vertebral faucet, examine the liquid cedredbrospinal, and an electroencephalogram (EEG), that measures the electric activity of the brain.

Treatment Equipe

The treatment of tumor of primary brain, including oligodendrogliomas, is different to treat tumors in the somewhere else body. Neurosurgery demands a lot more precision than most of the other surgeries. Also, a lot of medicinal drugs cannot cross the barrier of blood brain. Therefore, the therapies that are used to treat oligodendrogliomas, and the secondary effects of these therapies, are completely complex.

The treatment occasions the more to day are available of teams of medical professionals, multi-disciplinaires and experienced composed from doctors, the nurses, and the technologues that specialize themselves in cancer (the oncology), the neurology, the medical imagery, the therapy of drug or radiance, and the anesthedsiologie.

The present clinic, the treatments, and the prognostic

Oligodendrogliomas and the other tumors of primary brains are diagnosed, or brought up, in the degrees of severity of I to IV. I to classify the tumors have cells that are not cunning and are almost normal in the appearance. Classify tumors II have cells that seem to be lightly abnormal. Classify tumors III have cells that are cunning and clearly abnormal. Degree IV, the type more harsh of tumors of brain, contain quick spreadingand the abnormal cells. Well defined Oligodendrogliomas generally is I climbs or climbs of the tumors II. Anaplastic oligodenrogliomas generally brought up III or the tumors of IV of step.

The standard treatment for all degrees of oligodendrogliomas is the surgery to remove the tumor completely. This surgery generally is helped by a system of direction of picture that allows the surgeon to determine the road more effective to the tumor location. Roughly the half of relief of gain of patients of oligodendroglioma of the pressure of increased intracranial after having completes the abduction of their tumors. The other half demands one bypasses vertebral fluid to allow the drainage of the additional liquid.

In some examples of oligodendroglioma, the tumor is inopedrable or completely cannot be removed. The patients with oligodendrogliomas inopedrable generally are treated with radiance therapies. Oligodendrogliomas is among the only tumors of brain that can be treated with success with a chemotherapy type called COLLECT CALL (Procarbazine, CCNU or lomustine, and Vincristine). Chemotherapy is used of ordinary one only in case of anaplastic oligodendrogliomas recurrent.

Refusal: I the American medical Assocation not a M.D. The one to consult for medical specific precise the news to your condition.

The short response: there is the two types (benign and cunning) of oligodendroglioma; complete the abduction by surgery cannot be possible because of the form of him but radiotherapy or chemotherapy would help minimize what left.

Detailed response:
The histopathologic classifies oligodendrogliomas is controversial. Currently it the most ordinarily used classifying the outline is based on the year 2000 Healths Organization World-wide (THAT) the indications. Oligodendrogliomas generally is dichotomized in the degree II (the low degree) and classifies III (the high degree) the tumors. The designation of degree oligodendroglioma III (the high degree) subsumes generally the diagnostic preceding one of anaplastic or cunning oligodendroglioma.

This is a tumor of rare brain and the site and the capacity to remove completely and the sensitiveness to radiance determines the remedy.
