The tumor gets its name from the cells it forms on: oligodendrocytes, which usually play a role in protecting nerve cells. #1. An oligodendroglioma is a primary brain tumor, meaning it originates in the brain rather than having spread from another location in the body. Oligodendroglioma Oligodendroglioma Oligodendroglioma is a brain tumor arising from oligodendrocytes, the name for cells that normally wrap around and provide support to nerve fibers in the brain. With tumors ≥ 5 cm, oligoastrocytoma was more similar to astrocytoma.. The cause of oligodendroglioma is still unknown, though certain risk factors exist: Age. Exposure to radiation. Oligodendroglioma NOS. Weakness in the arms, face or legs. Oligodendrogliomas, the second most common histological subtype of gliomas, are infiltrative glial neoplasms that typically occur within the cerebrum of middle-aged to older adults and, like astrocytomas, diffusely invade normal brain structures. When glial cells form a glioma tumour, damage can be seen in the DNA and they no longer undergo apoptosis, which means programmed or purposeful cell death. Gliomas may be considered astrocytoma, oligodendroglioma, or ependymoma. Ten years after Cairncross and Macdonald 4 first reported remarkable examples of tumor shrinkage after chemotherapy in patients with recurrent anaplastic oligodendroglioma, it is clear that oligodendrogliomas are among the most chemosensitive of all human solid malignancies. Oligodendroglioma is a rare tumor that forms in either the brain or spinal cord. While procarbazine, lomustine (CCNU), and vincristine sulfate, a chemotherapy regimen designated PCV, are most often . Therapeutic irradiation can lead to the development of astrocytomas. A DNET is a rare benign neoplasm, usually in a cortical and temporal location. The side effects of an oligodendroglioma in the frontal lobe may include paralysis and seizures. For a treatment plan to be successful, several techniques should be employed to guarantee a reduced chance or reoccurrence of the tumor. There are no known causes of oligodendroglioma. We sequenced 12 pairs of primary and recurrent 1p/19q-codeleted tumors (Additional file 1: Table S1).Of these tumors, 2 progressed from WHO grade II to grade III histologically, 9 remained as the same grade (8 as grade III, 1 as grade II), and 1 grade III tumors were diagnosed as grade II at recurrence (Additional file 2: Figure S1). Grade 1 is considered benign, but unfortunately Oligos are never grade 1. The main types of supportive cells in the brain include astrocytes, oligodendrocytes, and ependymal cells. Cabbage hence should be eaten with Radiation treatment for Oligodendroglioma (Brain Tumor). Grade 2 means it is slower growing, Grade 3 (aka anaplastic oligodendroglioma) is faster growing. Oligodendrogliomas may be diagnosed at any age but occur most commonly in young and middle-aged adults, with a median age at diagnosis of 40-50 years.
