What is the introduction to glioma disease

Many diseases come on without warning, and the pain they bring to patients is immeasurable. If headaches, vomiting, vision loss, diplopia, epileptic seizures, and mental symptoms occur, you should suspect that the patient has a glioma. Let us now learn about the introduction to glioma.

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.

From an epidemiological point of view: glioma is the most common among various intracranial tumors. Among gliomas, astrocytoma is the most common, followed by glioblastoma multiforme, and ependymoma ranks third. Gender is more common in males, especially in glioblastoma multiforme and medulloblastoma, males are significantly more than females. Age is mostly between 20 and 50 years old, with 30 to 40 years old as the highest peak. In addition, it is also more common in children around 10 years old, which is another small peak. Each type of glioma has its own age of occurrence. For example, astrocytoma is more common in middle-aged people, glioblastoma multiforme is more common in middle-aged people, ependymoma is more common in children and young people, and medulloblastoma mostly occurs in children.

Symptoms mainly manifest in two aspects. 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.

Diagnosis: The diagnosis is made based on age, gender, site of occurrence and clinical course, and the pathological type is estimated. In addition to the medical history and neurological examination, some auxiliary examinations are also needed to help with the diagnosis and qualitative analysis.

Treatment: Currently, the common treatments for gliomas at home and abroad are surgery, radiotherapy, chemotherapy, X-knife, gamma knife, etc.
