A brain tumor is an abnormal growth of cells in the brain inside the skull, which can be cancerous or noncancerous (benign) . It is defined as any intracranial tumor created by abnormal and uncontrolled cell division, normally either in the brain itself (neurons, glial cells (astrocytes, oligodendrocytes, ependymal cells), lymphatic tissue, blood vessels) in cranial nerves (myelin-producing Schwann cells) in the brain envelopes (meninges), skull, pituitary and pineal gland, or spread of cancers primarily located in other organs (metastasis) tumors. Primary brain (true) are generally located in the posterior fossa in children and in the anterior two-thirds of the cerebral hemispheres in adults, although they can affect any part of cerveau.Aux United States in the years 2005, it was estimated that there were 43,800 new cases of brain tumors (Central Brain Tumor Registry of the United States, primary brain tumors in the United States, Statistical Report, 2005-2006), [1] representing 1.4 percent of all cancers, 2.4 percent of all cancer deaths [2], and 20-25 percent of pediatric cancers. [2] [3] Ultimately, it is estimated that there are 13,000 deaths annually in the United States alone as a result of brain tumors. [1] Many meningiomas, with the exception of some tumors located at the base of the skull, can be surgically removed successfully. In more difficult cases, stereotactic radiosurgery, such as Gamma Knife radiosurgery, remains an option viable.Adénomes pituitary Most can be removed surgically, often using a minimally invasive approach through the nasal cavity and skull base (trans- nasal transsphenoidal approach). Large pituitary adenomas require a craniotomy (opening the skull) for their removal. Radiotherapy, including stereotactic approaches, is reserved for cases inopérables.Bien that there is no generally accepted therapeutic management for primary brain tumors, an attempt at surgical removal of the tumor or at least cytoreduction (that is , removal of the tumor, whenever possible, to reduce the number of tumor cells available for proliferation) is considered in most cases. [7] However, due to the nature of these infiltrating lesions, tumor recurrence, even after a withdrawal, apparently complete surgical, is not uncommon. Several studies of current research aimed at improving the surgical removal of brain tumors by labeling tumor cells with a chemical (5-aminolevulinic acid) which leads to fluorescence [8]. Postoperative radiotherapy and chemotherapy are part of standard therapy for malignant tumors. Radiation therapy may also be administered in case of “low grade” gliomas, when a significant tumor burden reduction could be achieved chirurgicalement.Les survival in primary brain tumors depend on tumor type, age, functional status the patient, the extent of surgical resection of the tumor, to name a few. [9] UCLA Neuro-Oncology publishes survival data in real time for patients with this diagnosis. They are the only institution in the United States that shows how a brain tumor patients are performing on current therapies. They also show a list of chemotherapy agents used to treat tumors up grade.Les glioma patients with benign gliomas may survive for many years [10], [11] while survival in most cases of glioblastoma multiforme is limited to a few months after diagnosis if treatment is ignoré.L option only main treatment for metastatic tumors is surgical removal, followed by radiotherapy and / or chemotherapy. Multiple metastatic tumors are generally treated with radiotherapy and chemotherapy. Stereotactic radiosurgery, such as Gamma Knife radiosurgery, remains a viable option. However, the prognosis in such cases is determined by the primary tumor, and it is generally pauvre.Une bypass operation is used not as a cure but to relieve symptoms. [1] The hydrocephalus caused by blockage of drainage of cerebrospinal fluid can be removed from this operation. [Edit] The search for a treatment with stomatitis virus vésiculeuseEn 2000, researchers at the University of Ottawa, directed by John Bell PhD., found that the vesicular stomatitis virus, or VSV can infect and kill cancer cells without affecting healthy cells, when administered in combination with interferon. [12] The initial discovery of the oncolytic properties of the virus have been limited to only a few types of cancer. Several independent studies have identified several types more susceptible to the virus, including glioblastoma multiforme cancer cells, which represent the majority of tumors cerveau.En 2008, researchers artificially created strains of VSV that were less cytotoxic to normal cells. This advance allows the administration of the virus without co-administration with interferon. Therefore the administration of the virus can be administered intravenously or by the olfactory nerve. In research, a human brain tumor was implanted in the brains of mice. The V
