Mutations and deletions of so-called tumor supressor genes are incriminated in some forms of brain tumors. Patients with various inherited diseases, such as Von Hippel-Lindau syndrome, multiple endocrine neoplasia, neurofibromatosis type ... http://glioma-cancer.com/2008/04/18/metastatic-cancers-are-far-more-common-than-primary-tumors-of-the-brain-and-spinal-cord/ An Overview Adult brain tumors are diseases in which cancer cells begin to grow in the tissues of the brain. Tumors that start in the brain are called primary brain cancer. Tumors that start in another part of the body but spread to the brain are called secondary brain cancer. Secondary ... http://glioma-cancer.com/2008/04/18/brain-cancer-in-adults/ BACKGROUND : Brainstem tumors represent 10% of central nervous system tumors, accounting for 30% of pediatric posterior fossa tumors. AIMS : The aim of this study was to clinicopathologically correlate 45 cases of brain stem gliomas and determine the occurrence and prognostic significance of p53 expression. MATERIALS AND METHOD :  45 ... http://glioma-cancer.com/2008/04/18/a-clinicopathological-study-of-45-cases-with-p53-immunohistochemistry/ Brainstem gliomas are tumors that occur in the region of the brain referred to as the brain stem, which is the area between the aqueduct of Sylvius and the fourth ventricle. Although various systems are used to classify these tumors, the authors have divided brainstem gliomas into 3 distinct anatomic ... http://glioma-cancer.com/2008/04/18/background/ Gliogene, a new international, multi-institutional, five-year study, will try to determine genetic risk factors that might help predict primary brain tumors known as gliomas. Gliomas are a rare but serious type of brain cancer that seem to run in some families. Purpose of study Approximately 5% to 10% of glioma cases run in families, ... http://glioma-cancer.com/2008/04/18/worldwide-study-looks-at-inherited-brain-tumors-rare-malignant-primary-tumors-examined/ The symptoms of brain tumors depend on tumor size, type, and location. Symptoms may be caused when a tumor presses on a nerve or damages a certain area of the brain. They also may be caused when the brain swells or fluid builds up within the skull. These are the ... http://glioma-cancer.com/2008/04/18/symptoms/ A Glioblastoma is a type of a primary brain tumor. Primary brain tumors are those that arise from the brain itself rather than traveling or metastasizing from another location in the body. Approximately 17,000 new cases of primary brain tumors are treated each year in the United States. Primary brain tumors ... http://glioma-cancer.com/2008/04/18/glioblastoma/ The existence of rogue stem cells that refuse to die explains why an aggressive brain tumor known as glioblastoma typically isn’t extinguished by radiation therapy.  A study in the December 7, 2006 issue of Nature* shows that the therapy fails to kill a small but potent fraction of cancerous cells – ... http://glioma-cancer.com/2008/04/18/glioma-cancer-3/ The terms spirituality and religion are often used in place of each other, but for many people they have different meanings. Religion may be defined as a specific set of beliefs and practices, usually associated with an organized group. Spirituality may be defined as an individual's sense of peace, purpose, ... http://glioma-cancer.com/2008/04/18/for-many-people-spirituality-and-religion-have-different-meanings/ Nine human malignant gliomas (2 astrocytomas grade III and 7 glioblastomas) were analyzed using comparative genomic hybridization (CGH). In addition to the amplification of the EGFR gene at 7p12 in 4 of 9 cases, six new amplification sites were mapped to 1q32, 4q12, 7q21.1, 7q21.2-3, 12p, and 22q12. Nonrandom chromosomal ... http://glioma-cancer.com/2008/04/18/comparative-genomic-hybridization-of-human-malignant-gliomas-reveals-multiple-amplification-sites-and-nonrandom-chromosomal-gains-and-losses/
