For patients with brain gliomas, it is recommended that they visit a local hospital as soon as possible in the early stages of the disease. A physician with extensive surgical experience should help assess the current situation through cranial CT, cranial MRI, and enhanced cranial MRI scans, to determine the location, scope, and range of edema of the glioma, as well as its proximity to surrounding blood vessels and nerves, and to establish a personalized surgical treatment plan. Through surgery, the glioma in the brain should be removed as completely as possible. After surgical treatment, most patients can achieve satisfactory outcomes. However, since gliomas are malignant tumors, it is necessary to follow up surgery with early radiation and chemotherapy treatments.

How is glioma graded?

According to the characteristics of pathology, gliomas are divided into grades one to four. Grade one is a low-grade malignancy, more benign tumor, accounting for about 5%, with a relatively high probability of successful surgical outcomes. Grade two accounts for about 35%, and after comprehensive treatment including surgery, the survival rate can reach five to ten years, or even longer. Grade three usually develops from grade two, with relatively poor prognosis, and the average survival period is about two years. Grade four, the most malignant glioma, also known as glioblastoma, accounts for about 30%-40%, with an average survival period of less than one year, and very poor outcomes.

Glioma causes

In clinical practice, the etiology of gliomas is not very clear. It is not as straightforward as how smoking can easily lead to lung cancer or how cirrhosis can easily lead to liver cancer; many factors are speculative. For example, the most common theory in clinical practice involves genetics. Any form of genetic mutation or chromosomal mutation can induce the development of a glioma. For instance, excessive radiation exposure and drug abuse, and even maternal-fetal transmission or a genetic predisposition, could cause chromosomal abnormalities in patients, potentially leading to the formation of gliomas. However, the most fundamental cause has not yet been clearly identified.

Is glioma a terminal illness?

Glioblastoma is not an incurable disease. Patients with glioblastoma have a type of malignant tumor that tends to grow rapidly. These tumors often adhere to surrounding brain tissue in the early stages, making complete surgical removal difficult. If any glioma cells remain after surgery, the tumor tissue will gradually grow over time. Thus, patients with glioblastoma are prone to recurrence, but it is not an incurable disease. If early detection and surgical removal can be achieved, and supplemented by radiotherapy and chemotherapy, it can maximize the therapeutic effects of the surgery, thereby effectively improving the prognosis and delaying the progression of the disease. This approach can relatively extend the patient's lifespan, and some patients may even achieve long-term survival.

Is glioma malignant?

Glioblastoma is a type of malignant tumor, which generally grows at a fast pace. In the early stages of the disease, the glioma often adheres to the surrounding tissues, posing significant challenges for future complete surgical removal. At the same time, extensive cerebral edema occurs around the glioma. If prolonged, this can lead to a serious increase in intracranial pressure, manifesting as repeated headaches, dizziness, nausea, and vomiting in the patient. Over time, this condition may also lead to optic nerve atrophy, resulting in decreased vision and visual field defects. Diagnosis generally benefits from cranial CT or MRI scans, but definitive diagnosis still requires surgical removal of the tumor. A small amount of tumor tissue is typically retained for pathological biopsy.
