Glioma is a very common malignant tumor in the brain, with malignancy levels divided into grades I, II, III, and IV. Grade I has the lowest malignancy, close to benign, and patients have a good prognosis after complete surgical removal. Grade IV gliomas have the highest malignancy and are also known as glioblastomas. These tumors do not have clear boundaries, making complete surgical removal impossible, and they are highly prone to recur after surgery, leading to poor prognosis. Even with the most advanced treatments, such as surgery combined with radiotherapy, chemotherapy, and gene therapy, the average survival time is only 12-14 months, and without treatment, the average survival time is only four months.

Is a glioma benign or malignant?

Glioblastoma is the most common form of malignant tumor inside the skull, and the vast majority of glioblastomas are highly malignant. Once changes in this condition are detected, generally, the patient doesn't have much time left. If it is a relatively better glioblastoma, which means it is highly differentiated, the survival time is about 1-2 years. For some poorer glioblastomas, or those with low differentiation, their survival period is often only about six months, and they continuously spread along with nerve fibers to the surrounding areas. They might even metastasize to distant places through cerebrospinal fluid, blood, lymph, and other means. Therefore, even if surgery is used to remove a single lesion, other parts of the body may still demonstrate metastatic lesions. Hence, the treatment approach for this is comprehensive.

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 Symptoms

For patients with glioma, they often exhibit certain degrees of headache and dizziness, with headaches typically located bilaterally in the frontal or temporal regions. The nature of the pain is relatively sharp, manifesting as intermittent attacks that progressively worsen over time. Long-standing gliomas easily induce a notable increase in intracranial pressure, presenting with severe headaches, nausea, vomiting, and even a decrease in vision or visual field defects. When the glioma is located in the parietal lobe and affects important motor function areas, it can lead to unilateral or bilateral limb weakness, numbness, pain, and possibly even trigger hemiplegia.

Gliomas grow where?

Glioma is a stubborn malignant tumor of the central nervous system that originates from neuroglial cells. Therefore, gliomas can occur anywhere there are neuroglial cells. Clinically, based on the common sites of the tumors, gliomas can be divided into supratentorial gliomas, which are mostly found in the cerebral hemispheres, frontal lobes, temporal lobes, and parietal lobes, and are less common in the occipital lobes. There are also infratentorial gliomas primarily in the cerebellum. Additionally, a few gliomas are found in the brainstem and spinal cord.

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.
