For patients with glioma, the primary treatment method is still to surgically remove the tumor, followed by postoperative radiotherapy, chemotherapy, and other related treatments. The main treatment principle is to detect, diagnose, and treat early. During surgery, the tumor should be removed as completely as possible, and it is advisable to receive postoperative radiotherapy and chemotherapy early to effectively consolidate the surgical treatment effects. This helps to kill tumor cells to the greatest extent, slow down the probability and timing of tumor recurrence, and extend the patient's lifespan as much as possible. Therefore, for patients with glioma, it is recommended to choose to seek surgical treatment at well-known, top-tier hospitals locally.

Early symptoms of glioma

For patients with glioma, in the early stages of the disease, symptoms often manifest as mild headaches, dizziness, nausea, and vomiting. The symptoms are usually mild and tolerable for patients, and most patients do not pay enough attention, which can easily lead to missed and misdiagnosis. However, as the tumor volume increases, the patient's symptoms of headache, dizziness, and other discomforts gradually worsen, and may even show episodic outbreaks and a persistent worsening state. In addition to headaches and dizziness, some patients also exhibit significant motor dysfunction, exhibiting symptoms such as hemiplegia and aphasia. Patients with severe conditions may even experience widespread intracranial pressure increase, and life-threatening conditions due to the induction of brain herniation.

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.

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.

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.

Clinical manifestations of glioma

For patients with glioma, as it is a malignant tumor with a rapid growth rate, they may exhibit severe symptoms at the early stage of the disease, including severe headaches, dizziness, nausea, vomiting, loss of appetite, poor mental state, poor sleep quality at night, frequent insomnia and nightmares, and easy waking up. As the tumor increases in size, it often causes an increase in intracranial pressure. In severe cases, this may lead to optic disc edema, decreased vision, and visual field defects. Additionally, some patients may experience impairment in motor functions, manifesting as hemiplegia, and in some cases, aphasia. It is advised to undergo surgery in the early stages, followed by radiotherapy and chemotherapy.
