Analysis of what is glioma disease

Because the social environment is becoming increasingly harsh, the incidence of various tumor diseases is rising sharply every year. Glioma is a common brain nerve tumor disease. Everyone knows that this disease is very harmful to patients, but some people can't say what kind of disease it is. Let me explain to you what glioma disease is.

Gliomas are tumors that occur in the neuroectoderm, so they are also called neuroectodermal tumors or neuroepithelial tumors. Tumors originate from neural interstitial cells, namely glia, ependyma, choroid plexus epithelium, and neural parenchymal cells, namely neurons. Most tumors originate from different types of glia, but based on their histological origins and similar biological characteristics, various tumors that occur in the neuroectoderm are generally called gliomas.

There are two main manifestations of glioma symptoms. One is increased intracranial pressure and other general symptoms, such as headache, vomiting, vision loss, diplopia, epileptic seizures and mental symptoms. The other is local symptoms caused by the compression, infiltration and destruction of brain tissue by the tumor, resulting in neurological dysfunction.

When you have a glioma, as the tumor gradually grows, it forms an intracranial space-occupying lesion, and is often accompanied by surrounding brain edema. When it exceeds the compensation limit, the intracranial pressure increases. When the tumor blocks the circulation of cerebrospinal fluid or compresses the veins, causing venous return obstruction, the intracranial pressure increases further. If bleeding, necrosis, and cyst formation occur in the tumor, the process can be accelerated. When the increase in intracranial pressure reaches a critical point, the intracranial volume continues to increase slightly, and the intracranial pressure will increase rapidly. If intracranial pressure monitoring is performed, when the pressure reaches 6.67-13.3 kPa of mercury, a plateau wave will appear. The plateau wave appears repeatedly and lasts for a long time, which is a clinical sign. When the intracranial pressure is equal to the arterial pressure, the cerebral blood vessels are paralyzed, the cerebral blood flow stops, the blood pressure drops, and the patient will die soon.

The diagnosis of glioma is based on an analysis of its biological characteristics, age, gender, prevalent site and clinical course. Based on the medical history and physical signs, auxiliary examinations such as electrophysiology, ultrasound, radionuclide, radiology and magnetic resonance imaging are used. The positioning accuracy is almost 100%, and the qualitative diagnosis accuracy is over 90%.

At present, the treatment of glioma at home and abroad is generally surgery, radiotherapy, chemotherapy, X-knife, gamma knife, etc. Glioma is a brain tumor disease with high recurrence. There is no effective means to prevent recurrence. The recurrence time of this disease depends on the degree of differentiation and treatment. Generally, traditional treatment mostly relapses within 1-5 years. Regular follow-up visits and active treatment after recurrence.
