Childhood cancer: the brain tumors
In the brain can cause a lot of different tumors.
The brain tumors can arrive in the very different parties of the brain. There are also a lot of different types of tumors in the brain. The a principal one arrives the brain tumors in the children include:
- Gliomas: Glioma is a collective term for the resultant tumors of the neuroglia. As the neuroglia supporting and the fabric sheath called the nervous system. Gliomas begins often with the brain neuroglia. Notably common is a form of glioma, the so-called astrocytomas.
- Medulloblastomas also is referred to as "cerebellar glass.
- Ependymomas: Going out Of the tumor of glial of Empendym. The Empendym is a single cell clothing cells of glial of the cerebral ventricules and of central canal of the vertebral rope.
- Craniopharyngioma, the tumor of pocket of Rathke also is called a tumor, that already is in the embryo by an aberration.
- Meningiomas is benign tumors to slow development suppose that meninges, the cells of surface of the mother of arachnoid (the canvass of spider of skin of the brain and the vertebral rope.
- Pituitary Adenomas: Pituitary Adenomas is tumors of the pituitary gland or pituitary gland. Certain of these tumors produce hormones that intervene in the buckles of check and reactions of the pituitary hormones. An example of an endocrine pituitary adenoma is the prolactinoma.
1 in 3000 children is affected.
The brain tumors represent 20 percent, the biggest group of cancer in childhood. The frequency of event of a tumor of brain in childhood is almost 1 disease by 3000 children, where all ages can be affected. The most frequently nevertheless the tumors of brain arrive before the age of ten.
The symptoms depend on the nature of the tumor, place in the brain and the size of the tumor of. The symptoms can vary strong. They depend first on the tumor type, and deuxia¨mement the location of the disease and the size of the tumor of. Very often nevertheless it this is also
Depend on the location of tumor, the other symptoms arrive:
- The cerebellum (eg, medulloblastoma, ependymomas) : the muscle relaxation, the unsteady gait, the tremblings and the uncertainty during the movement execution, the non contained movements of the globes eyepieces, the speech disorder.
- Brainstem (eg astrocytoma, glioma and of others) : hemiplegia, the eye and the paralysis of muscle of the face, the downhill of difficulty, the changes in the mood.
- The midbrain (eg astrocytoma, craniopharyngioma, pituitary adenoma) : jumbled the vision, the disturbances of regulation of temperature and the fluid balance, the disorders of growth and sleep.
- The brain (eg, astrocytoma, meningioma, ependymoma) : the partial paralysis, the mental disorders, the sensory disturbances, visual disturbances and of speech.
The vast investigations are necessary.
To diagnose a brain tumor, the complaints, the conclusions of physical examination and the examination of EEG (first EEG: electroencephalograph, a recording of waves of brain) and the RADIO, the ultransonic sounds and the conclusions of imagery of magnetic resonance of the head. The investigation of the can of nervous water) (CSF furnishes more complete insights. Nerve water by a so-called puncture lombaire, a puncture of ie of the canal the vertebral thorn to flower of obtained lombaire.
Therapy must be individual.
The therapy choice depends on the nature of the tumor just like his location and his size. Usually, chemotherapy, the therapy of radiance and are the eligible surgical abduction, every only or in the combination. The prognostic depends on the type of tumor, the location and the size, but also the age of the child: With the age growing children improves the prognostic. 8 years after the treatment, 40 percent of children lives with a medulloblastoma, 75 percent of patients with astrocytoma, almost 10 percent of these patients with a localized tumor in the brainstem and 70 to 80 percent of children with a craniopharyngioma.
