Mixed Gliomas Surgery Radiation Chemotherapy

Mixed gliomas are brain tumors that contain more than one type of cell. The prognosis is affected by the cell type with the highest grade present in the tumor.

Oligoastrocytoma (grade II): Oligoastrocytomas are slow-growing tumors composed of cells that look like astrocytes and oligodendrocytes.
Anaplastic oligoastrocytoma (grade III): These are higher-grade oligoastrocytomas. The average age of patients developing anaplastic oligoastrocytomas is 45 years.

Treatment of mixed gliomas may include the following:

Surgery plus radiation therapy with or without chemotherapy.
A clinical trial of external radiation therapy plus hyperthermia therapy or new methods of delivering radiation therapy.
A clinical trial of new anticancer drugs or biologic therapy following radiation therapy.
