Glioblastoma Introduction

Brain tumors can be a cause of seizures also, but these are very rare. Most epileptic patients have been tested for brain tumors, just

Glioblastoma is the most common and aggressive form of malignant brain cancer in adults. On average, 8 of every 100,000 people in the U.S. are diagnosed with glioblastoma every year – representing approximately 2% of all cancers diagnosed [1]. Glioblastoma tumors form when astrocytes, star-shaped cells which support and protect the brain, re-enter the cell cycle and start to rapidly divide. Because the brain is supported by a large network of blood vessels, tumors grow quickly and are difficult to remove surgically. Present treatments for glioblastoma are limited to surgery, radiation therapy, and chemotherapy; however, despite these interventions tumors are likely to regrow. Consequently, typical survival time following glioblastoma diagnosis is less than 2 years.

Glioma is a tumor that is a type of brain cancer. Glioma tumors are made up by cells called glial cells. Glial cells normally provide nutrition, oxygen, and structural support to the brain. Three types of glial cells can produce tumors. Gliomas are named after the type of glial cell that is involved in the tumor. A tumor is formed when the glial cells grow into an abnormal mass of tissue. Gliomas are one of the most common types of brain tumors that occur in adults.

Glioblastoma (pronounced like gleO blastoma) is an incurable brain cancer,Survival rate is usually measured in months.This became a word that was instantly defined, researched, dissected, feared, and tried to comprehend and understand by family,friends and acquaintances of Larry McKee (McKee)who was personally affected from this single word, it was quickly added to their vocabulary, because of the of the events that transpired on October 22, 2011 that forever changed lives “Glioblastomas are tumors that arise from the astrocytes- the star-shaped cells that make up the “glue-like,” or supportive tissue of the brain. These tumors are usually highly malignant (cancerous) because the cells reproduce quickly and they are supported by a large network of blood vessels.”(A.B.T A..) He was diagnosed with stage four.

Glioblastoma(GB) is the most common primary malignant solid brain tumor in adults1. Known for its aggressive characteristics and poor prognosis, the median survival rates of GB patients remain less than 18 months2,3. Tumor relapse owing to chemotherapeutic resistance is almost universal and GB is no exception, thus reflecting in high mortality and morbidity rates4. The WHO 2016 classification of brain tumors identifies GB tumors based on histology, molecular and genetic characterization into defined transcription profiles such as classical, neural, pro-neural and mesenchymal types5. Additionally, the commonly occurring genetic aberrations of primary GB are amplifications/mutations of EGFR, PDGFRA, PTEN, and of secondary GB are IDH1, MDM2

The primary ones include these types. Gliomas, the most common brain tumor involving the brain tissue. There are different grades and even types of gliomas. But if the tumor grade is higher, it will probably grow faster. Medullblastomas are brain tumors that in young children. Without treatment it will spread rapidly into the spinal fluid and other parts of the brain. But almost or half of the brain tumors found are benign. These types of brain tumors are usually Meningiomas and Neuromas. Meningiomas begin in the tissue membranes. Neuromas are in the nerves mostly in people over

Neuroblastoma (NB) is the most common extra-cranial solid tumor in children under 5 years age and arises from the embryonic neural crest .1It accounts for 8–10% of child- hood cancers and accounts for 15% of the deaths from cancer in the pediatric age group.2NB display extreme heterogeneity ranging from spontaneous regression to malignant progression3.NB Is stratified into three risk categories: low, intermediate, and high risk. Low-risk disease is most common in infants and good outcomes are common with observation only or surgery, whereas high-risk disease is difficult to treat successfully even with the most

Tumors can be classified into three types: 1) benign 2) pre malignant 3) malignant tumor. Benign tumors are those which are incapable of abrupt expanding and affecting the other healthy brain tissues. Premalignant tumor is a pre cancerous stage, if not treated properly it may lead to cancers. It is often considered as a disease. Malignant tumor grows rapidly with time an ultimately leads to death of patient. Malignant is a medical term describing a sever growth of a disease. The most common primary brain Tumors are gliomas, wherein 70% are in the group of malignant gliomas, glioblastoma multiform (GBM).The GBM is one of the highest malignant human

Glioblastoma Multiforme (GBM) is a primary central nervous system (CNS) cancer that causes tumors of the glial cells in the brain. The third most frequently reported histology overall, and the most common malignant histology1. It’s also the most common and the most malignant primary central nervous system tumors2. GBM accounts for 15.1% of all primary brain tumors and 46.1% of primary malignant brain tumors1. The Central Brain Tumor Registry of The United States (CBTRUS) estimated that 24,790 new cases of primary malignant brain tumors to be diagnosed in the United States in 20161.

Medulloblastoma, also called cerebellar primitive neuroectodermal tumor (PNET), is a fast growing embryonal tumors[A] located in the cerebellum caused by a glial cell (1)(4). The seven types of medulloblastoma are, classic,desmoplastic, nodular,, large-cell,(anaplastic), neuroblastic, glial differentiation, medullomyoblastoma, and melanotic. According to American Brain Tumor Association, medulloblastoma is relatively rare, and only accounts for two percent of all primary brain tumors(1).However, medulloblastoma is common in children making up to twenty percent of childhood brain tumors(2), while it is less common in adults(1). It is also more common in men than in women(3). (Thesis)

Common malignant brain cancers increase significantly according to statistical data collected by the National Cancer Institute. In 1984, the annual incidence rates of primary brain tumor and primary brain lymphoma also increased notably, the rate of lymphoma almost tripling,

Glioblastoma Multiforme is an extremely aggressive brain tumor that can drastically alter how the body moves, a person’s memory, vision, emotion, thought, etc (GBM Guide). Having something in your brain that has the potential to drastically

Another major breakthrough that occurred in the early 1970’s was the discovery of the first promising chemotherapy for glioma. A glioma is a malignant tumor that begins in the glial cells which surround the nervous system. Gliomas can be found in the brain and spinal cord. Researchers studied a chemotherapy drug called carmustine (BCNU) and

The brain is made up of millions upon millions of cells. These cells are formed from before birth, up until about 7 years old. Once these brain cells stop dividing, they are never meant to divide again. You can see that the division of brain cells is under strict regulation and control. When this control is lost in a single cell, then it starts dividing in an uncontrolled manner. All of the data obtained through research on cancer shows that this disease is caused by a rapidly dividing cell, with no regulators to stop it from dividing. As the cell makes more and more copies of itself, it grows to form a tumor. This is known as cancer.

According to world health organization (WHO), malignant tumors figure among the leading causes of morbidity and mortality worldwide 1. For instance, One of the most challenging type of tumors that have extracted a lot of attention in the field of cancer study is glioma which represents 30% of all brain tumors and 80% of
