It is still a time of “cancer”, especially cranial tumors. Now we are going to take a look at one of the most common malignant tumors in the brain – glioma. Glioma is a kind of tumor in the central nervous system of the brain. After getting glioma, headache, epilepsy, limb paralysis and numbness, speech impairment, vision loss, nausea and vomiting, as well as intracranial hemorrhage will occur, which may lead to coma and death if not treated in time. Under normal circumstances, there are many different kinds of cells in the brain, among which neurons are the basic units of the central nervous system and the basic components of the normal functioning of the brain center. In addition to neurons, other cells can be collectively called glial cells, these glial cells are equivalent to the neurons’ nutrient “porters”, mainly to supply blood oxygen to the neurons to ensure their normal work If one day the central glial cells do not grow and reproduce properly, but have a terrible If one day the glial cells in the center do not grow and multiply properly, but undergo a terrible “malignancy”, then the problem is serious. Since the cells in the central brain have many siblings, people have also classified tumors according to cell types, such as astrocytoma, oligodendroglioma (or oligodendroglioma), ventricular meningioma, mixed glioma, choroid plexus papilloma, neuroepithelial histoma of uncertain origin, neuronal and neuronal glial hybrid tumor, pineal parenchymal tumor, embryonal tumor, neuroblastoma …… so many classifications, it is also drunk to count them. In order to better diagnose and treat these tumors, they have been classified according to their severity, and the impact of each classification on the life expectancy of patients is different. The classification is as follows: Grade 1 (Class I): relatively rare. However, the treatment is more effective and can be cured without recurrence if total excision is possible. This is considered the most gentle little sister. Grade 2 (Class II): It mainly includes astrocytoma (astrocytic glioma), oligodendroglioma, oligodendro-astrocytic glioma, ventricular meningioma, and mucinous type hairy cell astrocytoma. If you have this type of glioma, if the risk of removing the tumor is relatively low and you can have a complete resection, then the average life expectancy after surgery can be 8 to 9 years; if you cannot have a complete resection and the risk value of the tumor is relatively high, then the possibility of recurrence is higher and the average life expectancy after surgery will drop to about 3 years. Grade 3 (Class III): mainly includes mesenchymal astrocytoma (astrocytic glioma), mesenchymal oligodendroglioma, mesenchymal oligodendroglioma-astrocytic glioma, and mesenchymal ventricular meningioma. Basically, they are all “mesenchymal”, which is even more powerful because it means that the patient may only have 1.5 to 3 years to live, and the recurrence after surgery is more violent. Without surgery, the survival period is even shorter. Grade 4 (Class IV): Glioblastoma (also known as glioblastoma multiforme) and gliosarcoma, which is the most powerful type of glioma. Having this type of tumor often means only an average life expectancy of 14 months, with a rebound soon after surgery of about 14 months. If left untreated, survival is even shorter, usually a few months. As the cells become less differentiated, the more malignant the tumor becomes. Therefore, among these four glioma classifications, grade 3 and 4 are very powerful and difficult to deal with, and are called high-grade gliomas; grade 1 and 2 are generally less powerful and can be effectively controlled in time, and are called low-grade gliomas. In addition, life expectancy is not only determined by the severity of the tumor, but also by the location of the tumor in the brain, the extent of surgical resection, and whether the tumor received the correct radiotherapy after surgery. The more thoroughly the tumor is removed, the less likely it is to recur. If the tumor grows in the central motor area of the brain, which governs limb activities, or in the brainstem, which is an important life center, then it cannot be completely removed in order to protect normal neurological functions, and the tumor is prone to recurrence; if the correct radiotherapy is given after surgery, it can effectively delay recurrence, and the outcome of disease development is better. However, not all gliomas need to be “cut” first. Some tumors that are small in size and do not grow in functional areas can be considered for living with tumors. If the tumor is deep and adjacent to important blood vessels and nerves, but the diameter of the tumor is not large and the patient does not have any symptoms, surgery may not be an option for the time being; if the tumor is intracranial and multiple, then the chance of surgery is lost, and these patients can consider radiotherapy after biopsy to clarify the pathological type. Although at the moment of finding out the glioma, the patient cannot decide how powerful the tumor is and where the tumor grows, what we can grasp is early diagnosis and treatment, listen to the doctor’s advice carefully, remove the tumor early if it can be removed early, and do a good job of radiotherapy and chemotherapy after the operation; if it cannot be removed, we should actively take a comprehensive treatment approach, not to let it go, but also not to The most important thing is that you can’t just leave it alone. Tumor is sometimes like a weed, which cannot be burnt out by the wildfire, so we must try to kill the tumor cells that may bring recurrence in the cradle, in order to live a long and good life.
