Brain tumor
A brain tumor is a Gewebswucherung in the area of the brain or the meninges. You can be more or less malicious, not set however i.a. any metastases. Mostly they arise of the nerve supporting fabric or in the area of the meninges or the Hypophyse or it is Tochtergeschwulste from other organs.
Good-natured/malicious brain tumors
Good-natured tumors replace the surrounding fabric, don't grow, however, and don't develop any metastases. They can, however, lead to an increased brain pressure by transfer of the Liquorsystems within the skull. Since they can replace also essential structures, the concept is good-naturedly misleading here and primarily refers to a possible cure since the tumors don't infiltrate into the surrounding fabric. Except for some very special exceptions metastasieren brain tumors never. Malicious Hinrtumoren grow infiltrating, this means they aren't sharply separated from the surrounding fabric. After an operation single cells in the edge area which then grow again so that it comes to a Rezidiv remain. This can depending on the Malignitätsgrad go faster or more slowly. An example of a good-natured brain tumor is the Meningeom. An example of a malignant tumor is the Glioblastom.
Symptoms
The symptoms can be multifarious and be able to to divide up roughly into three classes: focal neurological failures into dependence of the Lokalisation, focal amounts as a term of a symptomatic epilepsy or results of the brain pressure by the mass superseding effect.
Diagnosis
She is put by a magnet resonance tomography today, as a rule. A contrast medium photo is a note for viciousness. Another possibility is the positron issue tomography with Methionin, an amino acid with radioactive carbon which displays an increased micro vessel density and also therefore provides a clue for viciousness. This this method effortfully is and a cyclotron of its own requires, it isn't very spread and only reserved for large centers.
Therapy
She goes by the Lokalisation of the tumor, the size, the origin fabric and the general state of the patient. An operation typically partly is at first place at höhergradigen brain tumors into combination with chemotherapy a following, followed by a ray treatment. Tumor can become zugewartet at first, too. The radicalness of the operation is limited by the post-operative deficit to be expected, this means one operates as much as necessary and as little as possible. On the one hand, the ray treatment can of be carried out fractionated externally. Two or more radiate sources get, so oriented this the beams cross in the target fabric and the other fabric as little as possible damage. Fractionated indicates that one divides the treatment up in up to 40 sessions so that the other fabric can recover again and again. The Iod-Seed implantation is another ray treatment technique, an Iod 125 radiate source becomes stereo tactical brain operation with one in the tumor brought in and shines so to speak "from inside". There are different schemes for the chemotherapy, nowadays most frequently used these PCV and Temodal are, the latter can be combined with a ray treatment. PCV stands for Procarbazin, Cecenu and, Vincristin, a cycle lasts for 6 weeks and the medicine gets partial taken as tablets and sometimes as infusions over almost the complete time period. The therapy is effective, the secondary effects are frequent and distinctive. Temodal, active agent Temozolomid, is in the standard scheme on the first 5 days of a 28 day cycle in which intensified scheme always alternately a week every day and a week break, taken in the form of capsules. The therapy is also effective, the secondary effects occur more seldom and less distinctively, though. Dependent on the body surface, this one are . Dubois is charged from size and weight the dose of a chemotherapy with the formula of DuBois U.
