Gliomas

Gliomas are primary tumors that have their Urspung in the brain parenchyma. Symptoms and diagnosis are similar to other brain tumors. Treatment includes surgical excision, radiation therapy, and, in some tumors, chemotherapy. The excision is rarely curative.

Among the gliomas include astrocytomas, oligodendrogliomas, ependymomas, medulloblastomas and. Many gliomas infiltrate the brain tissue diffuse and irregular.

Among the gliomas include astrocytomas, oligodendrogliomas, ependymomas, medulloblastomas and. Many gliomas infiltrate the brain tissue diffuse and irregular. Astrocytomas are the most common glioma. They are classified according to increasing malignancy grade 1 or 2: low-grade astrocytomas grade 3: anaplastic astrocytoma grade 4:. Glioblastomas, including the malignant glioblastoma multiforme low-grade or anaplastic astrocytomas tend to occur in younger patients and can move in glioblastomas (secondary glioblastomas). Glioblastomas chromosomally contain heterogeneous cells. You can de novo development (primary glioblastomas), mostly middle-aged or elderly. Primary and secondary glioblastomas have different genetic characteristics that may change while developing tumors. Some astrocytomas contain oligodendroglioma cells; Patients with these tumors (so-called. Oligoastrocytoma) have a better prognosis than patients with pure astrocytomas. Oligodendrogliomas are among the most benign gliomas. They relate to the cerebral cortex mainly, especially the frontal lobe. Some oligodendrogliomas are characterized by a deletion of the p-arm of chromosome 1 (1p deletion), a deletion of the q arm of chromosome 19 (19q deletion) or both. These deletions speak for longer survival and a better response to radiation and chemotherapy. Anaplastic oligodendrogliomas are a virulent form of oligodendrogliomas and must be treated accordingly. Medulloblastomas and ependymomas are usually formed near the IV. Ventricle. Medulloblastomas develop mainly in children and young adults. Ependymomas, which are rare, occur v. a. when on children. Both types of tumors predispose to an obstructive hydrocephalus. The symptoms varies depending on the location (s. Frequent locations of manifestations of brain tumors). The diagnosis is the same as with other brain tumors. Medulloblastoma Image courtesy of William R.
