Is the mortality rate of glioma high?

When we talk about tumors, we all think that it is an incurable disease, especially malignant tumors. If you have it, you will face death. Glioma is a malignant tumor in the brain. The pain it causes to patients is unimaginable. Some people may even die. So, is the mortality rate of glioma high?

In the past 30 years, the incidence of primary malignant brain tumors has increased year by year, with an annual growth rate of about 1.2%, especially in the middle-aged and elderly population. According to literature reports, the annual incidence of brain glioma in China is 3-6 people per 100,000 people, and the annual death toll reaches 30,000.

Glioma usually has no typical symptoms at the beginning. As the tumor grows, it will show the following 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. The local symptoms vary depending on the location of the tumor.

Glioma is an infiltrative growth with no clear boundary between it and normal brain tissue. It is difficult to completely remove it, is not very sensitive to radiotherapy or chemotherapy, and is very prone to recurrence. Benign and malignant tumors growing in important parts of the brain are difficult to remove surgically or cannot be removed at all. Chemical drugs and general anti-tumor Chinese medicines are not ideal in efficacy due to the influence of factors such as the blood-brain barrier. Therefore, brain glioma is still one of the tumors with the worst prognosis among all tumors in the body.

Currently, the treatment method for glioma includes immunotherapy, which can greatly alleviate the patient's symptoms and improve the patient's survival rate and survival time.
