Types, tokens, especially the symptoms and treatment of astrocytomas
Fibrillary astrocytoma – a problem that can affect anyone. It develops in the brain structures of small-sized cells, which have star-like shape of astrocytes. Many patients are concerned about the prognosis and further course. Many patients live with this problem? What can distinguish the causes and recommendations on this issue?
General information about the astrocytoma
The Cells which form the tumor are of the type support. They are called "glial". Astrocytoma is a subtype of a fairly wide spectrum of tumor formation, which is called "glioma".
the Development of tumors does not depend on age. However, it is quite difficult to diagnose. For example, its density is almost identical to the brain substance, for the same reason, many studies fail to shed light on the current state of the patient.
Therefore most commonly used computer diagnostics or MRI for the detection and localization problems, and to conduct further diagnosis biopsy. A tumor cannot be completely determined, therefore, to eliminate only by surgical intervention.
The Problem may lie in the fact that the formation of cysts is associated with a mild increase.
A Benign tumor can become malignant and to determine it will be difficult.
- Pilocytic astrocytoma – a tumor of the 1st degree, which is considered benign. Observed slow growth that has marked limits. Polodna astrocytoma most often diagnosed in children. The place of localization – cerebellum, spinal cord. With this problem, doctors have learned to deal and can fix it without much harm to the body.
- Fibrillar-protoplasmic astrocytoma is a tumor formation of the 2-nd degree, which can also be attributed to benign entities. Growth, but slow, complete removal is difficult because there is no clear and distinct boundaries. A similar problem occurs in 20-30 year old patients.
- Anaplastic astrocytoma brain tumor, which refers to the 3rd type of malignancy. There is a rapid growth, which rarely lends itself to the necessary intervention. Most often, the problem manifests itself in men of middle age group.
Pilocytic astrocytoma occurs much more frequently than others. As for fibrillary astrocytomas, she is the "leader". Presents a tumor refers to the favourable options, only diagnosed since 2nd grade.
during the study, you can identify the histological structure of which is based on the basis of astrocytes fibrillar type, hence the disease got its name.
during the microscopic examination one can see that the affected cells have no differences from healthy, not observed no signs of cell atypia and abnormal mitoses. They are involved in a conglomerate, which is relatively homogeneous structure without visible necrotic changes with impossible to follow the germination structures of the vessels.
Exception that it would be appropriate to highlight – tumor nodules, capable of reaching large size. As a result of this process, and mismatch weight to the adequacy of the process of blood supply the tumor begins to necrotic.
later in the astrocytoma begins the formation of secondary cysts, which are filled with fluid. The main clinical manifestation of this neoplasm is considered to be the degree of localization. In most cases, begins active growth in the white medullary substance, which is then manifested in the form of seizures.
for this reason, the primary fibrillar astrocytoma may be associated with epilepsy in individuals who previously had no such problems. In the process of growth starts added secondary symptoms: paralysis, severe headache, disturbances of brain structures, discoordination movement disorders, etc.
Factors determining prognosis
This question is difficult to answer unequivocally. It is hard to determine the future state of the patient from whom the tumor was detected. Markers and factors may vary. Among the major include:
- tumor size
- clinical picture of the patient;
- timeliness in the implementation of treatment.
The tumor Itself is determined by using tomography. To establish the correct diagnosis is possible after the immediate removal and subsequent clinical studies. Other methods can provide onlysuperficial view of the problem.
The Basic treatment is surgical intervention, as markers of astrocytomas have clear boundaries. Quite good results can give radiation therapy and chemotherapy. In order to completely cure the disease, it is necessary to remove all affected areas and minimize neurological changes.
Correct diagnosis is the key to a quick recovery.
