Glioblastoma is an aggressive kind of brain cancer that can spread rapidly across the brain. It is the most malignant form of brain tumor. Typically, glioblastoma is treated with surgery, radiation therapy, and chemotherapy. In some cases, these treatments may also assist in putting the disease into remission.
Gliomas form when cells in the brain or spinal cord undergo DNA alterations. These alterations instruct the cells to continue surviving when they would otherwise perish. This can cause a tumor to grow rapidly and press against surrounding nerves or brain or spinal cord tissue.
Researchers are uncertain as to why gliomas form. However, hereditary problems and radiation exposure can also cause them. Scientists are aware that the glia is a non-neuronal brain and nervous system cell with multiple functions. They sustain nerve cells (neurons), aid in maintaining homeostasis and generate the myelin sheath, a protective sheath that envelops nerve fibers in the brain and spinal cord.
Glioblastomas originate from specialized brain cells called astrocytes. They are extremely hostile and tough to control. Astrocytes are glial cells in the brain and spinal cord that support neurons. They can detect levels of neurotransmitters in a synapse and respond by releasing chemicals that directly alter the communication between neurons.
In addition, they recycle the glutamate released during synaptic transmission and return it as glutamine, which is crucial for neuronal health. GP astrocytes are present in various brain regions, including the cerebellum, cortex, barrel cortex, and hippocampus. They are also essential for learning and memory.
Prior radiation to the head, a family history of the disease, and inherited cancer syndromes such as Li Fraumeni syndrome or neurofibromatosis type 1 are risk factors for glioblastoma. In most instances, the primary cause is unknown. Physicians utilize diagnostic imaging and biopsies.
Cancer is a disease that begins when cells mutate and grow uncontrollably. This occurs when genetic alterations cause cells to live beyond their expected lifespan. Over time, these alterations can lead to aberrant cell accumulation and glioblastoma formation in the brain. Glioblastomas are the most aggressive and rapidly progressing kind of brain cancer.
Gender and age are two characteristics that raise the risk of developing glioblastoma. Prior head radiation exposure can also raise the risk. Typically, surgery to remove as much of the tumor as feasible is followed by radiation and chemotherapy in treating glioblastoma. Chemotherapy is used to eliminate any leftover tumor cells, and it may inhibit the development of new cancers.
Those whose tumors exhibit the favorable gene marker MGMT methylation have a greater chance of survival. This research contributes to scientists' efforts to comprehend the role of methylation in brain tumors.
Although the exact cause of glioblastoma is unknown, it is believed that genetic alterations are responsible for its growth and spread. Certain rare genetic disorders, such as Li-Fraumeni syndrome, neurofibromatosis type 1, and Turcot syndrome, are associated with an increased chance of developing gliomas.
Genetic testing can assist physicians in determining whether a patient has glioblastoma or another type of brain cancer and the optimal treatment for that patient. Our world-renowned doctors at MD Anderson Cancer Center can run a molecular profile test to identify the genetic characteristics of a patient's tumor.
Based on their morphology (grade) and genetic makeup, glioblastomas are divided into two primary types. These are primary and secondary glioblastomas, respectively.
