Is there a difference between oligodendroma and oligodendroglioma?
No there is no difference between the two. However, there are
different types of oligodendrogliomas. This type of brain tumor
occurs in approximately 9 out of every 1,000,000 people. This is
about the rarest type of brain tumor. The brain is made up of many
supporting cells that are called glial cells. Any tumor of these
glial cells is called a glioma. Oligodendrogliomas are tumors that
arise from a type of glial cell called oligodendrocytes. These
cells are the specialized cells of the brain that produce the fatty
covering of nerve cells. As mentioned above, there are two types of
oligodendroglioma: the well-differentiated tumor, which grows
relatively slowly and in a defined shape; and the anaplastic
oligodendroglioma, which grows much more rapidly and does not have
a well-defined shape. Anaplastic oligodendrogliomas are much less
common than well-differentiated oligodendrogliomas.
So basically, if it is suspected that you or someone close to
you has an oligodendroglioma, hope that it is a well-differentiated
tumor. The prognosis and outcome are much brighter.
My husband was diagnosed with a well-differentiated oligo in
August of 2009. He underwent a craniatomy and awake open brain
mapping at MD Anderson. 100% of the tumor was resected. He has had
5 MRIs since then and they have all come back GOOD! However, a
warning, the recurrence rate for either type of oligo if pretty
high. Good luck. Hope this helps.
