1.What is glioma? A: Glioma is a malignant tumor of neuroepithelial tissue, commonly known as “brain cancer”. 2.Is the incidence of glioma high? A: Glioma is the most common primary intracranial tumor. Overseas clinical statistics show that the incidence of primary intracranial tumor is 21/100,000, and glioma accounts for about 60%. Domestic literature reports that glioma accounts for 35.26% to 60.96% of intracranial tumors. 3.How is the treatment effect of glioma? A: At present, the most common treatment method is surgery plus radiotherapy. Because of the infiltrative growth of glioma, surgery is often difficult to cut it completely. The overall efficacy is not good, especially for highly graded gliomas, which have highly variable growth characteristics, fast recurrence after surgery, poor prognosis, and are a serious threat to human health. Malignant glioma is the second leading cause of death among patients with tumors under 34 years of age and the seventh leading cause of death among patients aged 35 to 54 years, according to the World Health Organization’s 1998 publication ranked by mortality.
