Oligodendroglial Tumours: Brain Tumour of Glial Cells

Priya Pandey

Glioma is a kind of tumour which leads to formation of Cancer in the body.  Glioma occurs in Glial cells surrounding nerve cells and in brain and other parts of Central Nervous System. There are 3 types of glial cells which lead to production of Tumour: Astrocytomas (astrocytoma, anaplastic astrocytoma and glioblastoma), Ependymomas (anaplastic ependymoma, myxopapillary ependymoma and subependymoma) and Oligodendrogliomas (oligodendroglioma, anaplastic oligodendroglioma and anaplastic oligoastrocytoma). In this commentary Oligodendroglial Tumour, will be explained in detail. Oligodendrogliomas are one of the forms of glioma and they usually arises either from oligodendrocytes present in the brain or they arouse from a glial precursor cell. Glial cells are responsible for making fatty white substance (myelin) which covers the nerve cells. Myelin assists signals (impulses) in travelling quickly all along the nerves. It is infrequent kind of brain tumour and occurs mostly in adults. Oligodendrogliomas are primary brain tumors present in frontal lobe of the cerebrum (brain).On the basis of how quickly these tumours spread, Oligodendroglioma is divided into two groups: Low Grade (These are Benign Tumours and spreads slowly) and High Grade (These are malignant tumour and spreads rapidly).
