Glioblastoma Multiforme
Introduction
Within this paper an overview of Glioblastoma Multiforme, also known simply as Glioblastoma or GBM, the most common yet unfortunately most deadly form of brain cancer, will be provided. The purpose of this is to inform readers on the signs, symptoms and prognosis of this deadly disease in an effort to help provide a greater understanding, and to perhaps raise awareness, of a relatively unknown, yet extremely serious form of cancer.
Background
Glioblastoma multiforme manifests as a malignant tumor in the brain of the affected individual and is often formed of several cell types, making treatment difficult. It is the most common grade IV brain cancer and usually forms on either the temporal or frontal lobe, …show more content…

The prognosis who have contracted GBM is not optimistic, due to it being a fast growing, highly malignant tumor in the brain. The survival rate is considerably low, with only around 10% of patients surviving for five or more years even with proper treatment. Median survival of Glioblastoma is only 14.6 months with treatment while a two year survival rate is around 30%. Interestingly, children with high grade brain tumors such as glioblastoma have seen a five year survival rate at around 25% (“Glioblastoma (GBM)”, American Brain Tumor Association). A major pattern seen in those diagnosed with glioblastoma is that 80% of the patients had an extra copy of chromosome 7 The cancer also affects mostly adult white males. ("Demographic Variation in Incidence of Adult Glioma by Subtype, United States, 1992-2007," BMC …show more content…

It’s important to keep in mind that, because this tumor is located in an area that is very difficult to safely operate on and develops so quickly and aggressively, surgery is mostly looked at as merely the first stage in treatment, and not as an attempt at a cure. The surgery merely acts as a way to provide temporary relief for the patient by removing some of the cancerous tissue to relieve pressure. The method of operation is a craniotomy. In this operation, some bone is taken out of the skull so surgeons can attempt to remove the tumor. After the surgery is completed the bone is not immediately replaced, or in some cases the bone is not replaced at all. The main reason for this is so possible post operative swelling doesn’t cause further pressure. The next step is usually radiation therapy, which is used to treat many types of cancers because the radiation damages the cancer cell 's’ DNA to the point where it effectively kills the cell. Radiation may be conducted alone or in combination with other treatment methods such as chemotherapy. Radiation therapy may also be the first option if surgery is not possible. There are two main methods used in radiation therapy: Intensity Modulated Radiation Therapy (IMRT) and Stereotactic radiation therapy. The IMRT method is usually used with tumors that cannot easily be reached with surgery and are located near highly important locations in the brain. The radiation delivery system

Also the fact, “The prognosis (chance of recovery) depends on many factors including, age, tumor size, tumor type, and where the tumor is in the CNS” (“Brain Cancer- Patient Version”) Katherine had stayed at the hospital for a long 4 weeks until they decided to take out the brain tumor. The doctor told them many facts such as, “Primary brain tumors are classified by the type of cell or tissue, the tumor effects, and the location and grade of the tumor” (“Brain cancer information”)

These symptoms are caused by the build up of GM2-ganglioside in the nerve cells within the brain. It has a heterozygote frequency of 1:27 among Ashkenazi Jews, which is significantly higher than the average heterozygote frequency. (9). It can be divided into three forms; infantile, juvenile and adult, depending upon when the symptoms present, however most present as infantile form. This is indicative of sphingolipidoses which often present in early childhood and have a progressive neurodegenerative pathway.

Whitman’s body was taken to the morgue, his skull was put under the bone saw, and the medical examiner lifted the brain from its vault. He discovered that Whitman’s brain harbored a tumor the diameter of a nickel. This tumor, called a glioblastoma, had blossomed from beneath a structure called the thalamus, impinged on the hypothalamus, and compressed a third region called the amygdala. The amygdala is involved in emotional regulation, especially of fear and aggression. By the late 1800s, researchers had discovered that damage to the amygdala caused emotional and social disturbances.

In mesothelioma, radiation therapy can be used after surgery to try and eradicate any small tumors that couldn’t be viewed and resected during surgery. This is called adjuvant radiation therapy. Radiation therapy and IMRT can also be used on a palliative basis to ease the symptoms of pleural mesothelioma. These include shortness of breath, pain, bleeding and trouble swallowing.

It is described as a thick, white rough patch somewhere in the oral cavity. Depending on what stage the cancer has developed to, there are ways of treating it. Some examples would be surgery, radiation therapy, and chemotherapy. Removing the tumor, skin grafts, dental implants, removing teeth, part of the jaw, and lymph nodes are all techniques used of removing the cancerous area surgically. In the early stages, radiation therapy could be used to treat small tumors.

Stereotactic radiosurgery is a very focused type of radiation treatment used to carefully target brain tumors and other conditions. Barrow team offers several types of focused radiation (e.g., Gamma Knife® and CyberKnife® and IMRT) in order to choose the right type of treatment for the patient. No center in the southwest offers the breadth of radiation treatment options. This type of treatment is typically used to augment other treatments such as surgery and medication. How experienced is the team with stereotactic radiosurgery?

The breakage of cancerous cells from malignant brain tumors can cause it to spread to other parts of the brain and the central nervous system.

I chose the short history "The Bath" by Raymond Carver, for two reasons: for being the first suggestion and because already heard about this author. This tale involves an accident that leads to coma a boy on the day of his birthday. The child, Scotty, is run over on his way to school.

Radiation therapy is often used with chemotherapy and is performed before an operation. Radiation therapy is helpful for people with bone cancer that cannot be removed with surgery. It can also be used after surgery to kill off any remaining cancer cells(Bone Cancer - Symptoms and causes). In conclusion, bone cancer is a serious disease that has many different types, variants, and treatment options.

Brain Tumors Can Be Defeated With Multi-Disciplinary Approach The brain is a sophisticated, elegant and an elaborate mass of tissue and nerve cells. It seamlessly controls our senses, our personality, helps regulate vital body functions and controls how we move in our surroundings. When abnormal cells grow in the brain to develop a tumor, it can disrupt how we function and will require the ‘right’ treatment considerations that balance how the tumor is treated with how well our brain operates. Right treatment for brain tumor, however, needs a multi-disciplinary approach including intensive rehabilitation and post operative care, which is rarely available under a single roof.
