Glioma is the most common intracranial malignant tumor in clinical practice. Whether it can be completely cured depends on the malignancy degree, location, size, whether there is distant metastasis and whether the patient has underlying diseases. If the malignancy of glioma is low, located in non-functional area, small in size, without distant metastasis, and with strong repair ability, complete cure of glioma can be achieved by complete removal of glioma through surgery. Secondly, if the glioma is highly malignant and can only be partially excised in functional areas, and is accompanied by intracranial disseminated metastases, the patient’s own repair ability is poor. In this case, even if the patient undergoes surgery to remove the tumor and adjuvant radiotherapy or even targeted therapy, the glioma may still recur within a short time and cannot be completely cured, and the prognosis is very poor.
