However, the oncology specialists at the Florida Hospital Cancer Institute’s Brain and Spinal Care Program are experts at diagnosed and treating mixed gliomas and other brain tumors.

Mixed gliomas refer to brain tumors that are made up of two or more types of glioma cells, the cells that support the brain’s nerve cells. These tumors are often a combination of an astrocytoma and an oligodendroglioma—though some mixed gliomas may an ependymoma as well—and they are usually found in the cerebrum, the main part of the brain, though they may metastasize to other parts of the brain. The different tumor types in mixed gliomas may have different grades (i.e., one type may be more aggressive than the other); mixed gliomas are graded according to the most aggressive type of cancer cells.

Two types of mixed gliomas are oligoastrocytoma, a slow-growing, grade II tumor, and anaplastic oligoastrocytoma (grade III), a more aggressive version.  

Mixed gliomas account for about 1 percent of primary brain tumors, and are most commonly found in men and women between the ages of 20 and 59, though they are more common in men.
