Treatment of Brain TumorBY: Ritu Choudhary | Category: Other | Submitted: 2010-10-10 18:22:31
Glioma is type of tumor that originates in the brain or spine. The main problem in the treatment of a glioma is that the tumor cells of glioma as a unit does not stay together, but spread along the connective fiber paths of the brains. Hence they start affecting the normal brain cells even in the early stages of tumor. Gliomas do not percolate to other organs. The treatment of a glioma is not an objective cure but delaying further results in further degeneration of tumor leading to more new growths. Healing of a glioma is currently very difficult but treatment is possible. Among neurosurgeons it is often heard that, despite progress in many areas, the treatment of brain tumor has not progressed very much since the beginning of the development of the profession. This is partly true. Although advances in the field of image (CT, MRI, fMRI and PET scanning and other types of scans), anesthesia, surgical techniques and intensive care treatment truly has become, one is still not in full control of brain ie to heal a disease. That's because despite all efforts a brain tumor almost always comes back. Every neurosurgeon in practice who have every treated a patient successfully for brain tumor has a fear of possible prognosis. If you know that out of 100 patients the tumor will revive in almost 98 after elapse of some years is fearsome. This says something about the malignancy of the tumor, but one can never be sure the individual patient who is being treated will fall under 98 or is lucky enough to fall under 2. The demonstration of the aforementioned research has shown that brain tumor will be diagnosed in most cases after referral to the neurosurgeon. They will discuss the possibilities and limitations of surgical treatment. In most cases there are still no definite diagnosis known, first step will be to remove the tumor tissue by the pathologist for examination. Only then the final diagnosis is known. To obtain tissue, surgery is necessary. As stated above, the objective of an operation for a brain tumor two-fold: 1) First to come to the definitive diagnosis, and 2) to remove the tumor. This often happens during a single operation. Sometimes it is so small that a first operation is performed, where only a small piece of the tumor is removed in order to obtain a tissue diagnosis. This is called taking a biopsy. Based on that diagnosis (may be) a second surgery is performed which is usually a larger operation, with the objective to remove the tumor. A flap is created in the skull (craniotomy) in order to provide access to the part of the brains where the tumor is located. Biopsy A biopsy is nothing more than removing a piece of (tumor) tissue for pathology. This piece of tissue is examined by the pathologist, with the aim to achieve a clear "tissue diagnosis". In other words, the pathologist should answer the question: "what is the type of tumor. Doing biopsy alone without trying to remove the tumor will generally be done if the tumor in an unfavorable position in the brains (where the brain stem is located). Sometimes it's not even sure if it goes to a tumor, but there could also be an inflammation or other abnormality. In order to obtain information, it may be preferable to first take a biopsy, and only after a diagnosis it shall be decided whether a large (r) surgery is needed. A biopsy can be done in different ways. In practice there will always be a drill hole in the skull through which a biopsy needle goes inside the brains can be pushed to the point where there is tumor is located.
