Patients with gliomas often exhibit a range of symptoms including significant headaches, dizziness, nausea, and vomiting. As the tumor grows, it typically leads to an evident increase in intracranial pressure. Besides the original symptoms, some patients may also experience marked declines in vision, visual field deficits, and papilledema. The growth of the tumor inevitably compresses surrounding tissues, nerves, and blood vessels, leading to a variety of symptoms of neurological damage, such as noticeable hemiplegia, aphasia, and even abnormal sensations in one side of the body, characterized by numbness, pain, and a pins-and-needles sensation.

Can gliomas be inherited?

Gliomas have a certain hereditary proportion, but this is not an absolute concept. In clinical practice, there is no clear explanation for the pathogenic factors of gliomas, and theories are generally speculative. For instance, one factor is genetic nature, and there is also some familial clustering which supports the idea of a genetic predisposition. However, it is usually easier to identify purely genetic diseases, but gliomas often involve the inheritance of multiple genes, making it difficult to pinpoint the fundamental factors directly. Additionally, other factors include exposure to radiation and engaging in harmful work, such as producing methanol or solvents, etc. These can also cause genetic mutations leading to gliomas, so the issue is not necessarily solely genetic.

Glioma is a type of disease

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.

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.

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.
