Clinical medicine statistics show that glioblastoma accounts for the largest proportion of brain tumors, accounting for about 45% of the total. Gliomas can be subdivided into several forms, with astrocytomas and polar adult glioblastomas as common branches. Today, let’s talk about this most common brain tumor. The arrow shows the location of the glioma. Astrocytoma is the most common type of glioma. The pathological staging is grade I (astrocytoma), grade II (astroblastoma), and grade III-IV (glioblastoma multiforme). Grade I-II astrocytomas are of low malignancy, while grade III-IV glioblastoma multiforme has a rapid onset and is the most malignant tumor. Medulloblastoma is a highly malignant tumor that occurs in children between the ages of 2 and 10 years, and at least in young children a few months old. They are most often found in the presence of hydrocephalus. The arrow points to medulloblastoma. Oligodendroglioma is a low-grade malignant tumor, benign in nature, and many people call it a benign tumor. The growth rate is slow and calcified plaques are often seen within the tumor. The arrow shows an oligodendroglioma. Ventricular meningioma is also a type of glioma and is basically the same as astrocytoma. Glioma originates from glial cells in the brain and is the most common intracranial tumor. In the past 30 years, the incidence of primary malignant brain tumors has been increasing year by year, with an annual growth rate of about 1.2%, especially in the middle-aged and elderly population. According to literature, the annual incidence of glioma in China is 3 to 6 per 100,000 people, and the annual number of deaths reaches 30,000. In the early stages of glioma growth, there are usually no obvious symptoms. As the tumor grows, it slowly compresses the nerves in the brain, leading to dizziness and headache, vision loss, nausea and vomiting, etc. Also, due to increased intracranial pressure, it can lead to long-term headache and brain swelling, which affects normal life. Glioma is infiltrative growth, no obvious boundary with normal brain tissue, difficult to be completely removed, not very sensitive to radiotherapy and chemotherapy, very easy to recur, and benign and malignant tumors growing in important parts of the brain, difficult to be removed by surgery or not operable at all. In contrast, drug therapy can be difficult to achieve drug efficacy because of the obstructive effect of the blood-brain barrier. As a result, gliomas often have a poor prognosis. Surgery remains the mainstay of treatment for gliomas, joined by the development of the X-knife, and gamma-knife in recent years. However, as mentioned earlier, it is difficult to truly remove completely when resected because the growth boundary is unknown, and surgery does not guarantee eradication. In recent years, there have been many foreign studies testing the phagocytosis and inhibition of cancer cells by macrophages and others, although the translation of specific experimental results into treatments still needs to be verified in clinical trials. At this stage, it can only be said that modern medicine still does not have the means to cure glioma. Therefore, it is important to try to detect and treat glioma as early as possible and to actively cooperate. Regular medical checkups after middle age are an effective way to prevent and treat all tumors.
