About glioma disease introduction

Nowadays, people are under great pressure at work and in life, which brings with it various diseases, especially brain diseases. Gliomas are one of them. So, what kind of disease is glioma? Let's take a look at the disease introduction of glioma.

Neuroglioma, also known as glioma for short, is a tumor that occurs in the neuroectoderm. There are two types of tumors that occur in the neuroectoderm, one formed by mesenchymal cells, called gliomas; the other formed by parenchymal cells, called neuronal tumors. Since these two types of tumors cannot be completely distinguished from the perspective of etiology and morphology, and gliomas originating from mesenchymal cells are much more common than neuronal tumors originating from parenchymal cells, neuronal tumors are included in gliomas and collectively referred to as gliomas. Glioma is the most common intracranial tumor, accounting for about 45% of all intracranial tumors. It ranks second among childhood malignant tumors, with an annual incidence of glioma of 3-6 people per 100,000 people.

Glioma usually has no typical symptoms at the beginning. As the tumor continues to grow, it will show the following symptoms:

One is increased intracranial pressure and other general symptoms, such as headache, vomiting, vision loss, epileptic seizures and mental symptoms.

The other is local symptoms caused by compression, infiltration, and destruction of brain tissue by the tumor. The local symptoms vary depending on the location of the tumor growth.

The diagnosis of glioma mainly relies on imaging examinations such as CT, MRI, and MRS, and pathological examination is required for confirmation. WHO divides glioma into grades I, II, III, and IV according to the pathological properties of the tumor, with grade I being the least malignant and grade IV being the most malignant.

Once diagnosed, treatment should be started as soon as possible, mainly surgical treatment. For those with deep tumors, large tumors, or poor general condition that cannot be operated on, radiotherapy can be chosen. After surgical resection, radiotherapy and chemotherapy are also required according to the nature of the pathology. The recurrence rate of glioma is high and the prognosis is poor.
