How long can a person with glioma live?

In our daily lives, we are afraid of tumors, because no matter whether they are benign or malignant, they are extremely harmful to our bodies. Glioma is one of them. There are many clinical classifications according to the location of tumor growth. Among them, brain glioma has the highest mortality rate. The following is a detailed introduction to how long a glioma patient can live.

The life expectancy of glioma patients is affected by many factors, including their physical fitness, postoperative recovery, and the treatment methods adopted by the hospital. 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. Therefore, patients need to actively cooperate with doctors. Once the disease is discovered, it cannot be delayed and treatment must be carried out in a timely manner.

Radiotherapy: Radiotherapy is almost the routine treatment for all types of gliomas, but the evaluation of the efficacy varies. Except for medulloblastoma, which is highly sensitive to radiotherapy, and ependymoma, which is moderately sensitive, other types are not sensitive to radiotherapy. Some observations believe that the prognosis of radiotherapy and non-radiotherapy is the same. In addition, the impact of radiation-induced radiation necrosis on brain function should not be underestimated.

X-knife and γ-knife: Both belong to the category of radiotherapy. Due to the location of the tumor, the size of the tumor (generally limited to less than 3 cm) and the sensitivity of the tumor to radiation, the scope of treatment is limited. At present, it is believed that gliomas, especially malignant astrocytic grade III-IV or glioblastomas, are not suitable for R-knife treatment. However, with the continuous exploration of glioma treatment by gamma knife doctors, good results have been achieved in the clinical treatment of large gliomas with a tumor diameter of more than 3 cm.

Chemotherapy: In principle, it is used for malignant tumors, but chemotherapy drugs are limited by the blood-brain barrier and drug toxicity and side effects, and the efficacy is still uncertain. Commonly used BCNU, CCNU, VM-26, etc. have an effective rate of less than 30%.
