  Glioma - Diagnosis and Treatment Options at Mayo Clinic
Gliomas can be either benign (slow growing) or malignant (fast growing).
Treatment for a glioma -- and survival odds -- depends on tumor type, size and location, and the patient's age and overall health.
Gliomas can be complex, and there are a variety of techniques and procedures to treat them.

Gliomas are a class of tumor that develops from glial (neuroepithelial or support) cells.
Gliomas comprise nearly one-half of primary brain tumors and one-fifth of all primary spinal cord tumors.
Among patients with anaplastic astrocytoma and glioblastoma, there appears to be a definite increase in survival in those patients who have had at least a 97% or greater resection of their tumor, and in those patients whose tumor is located in the frontal lobe of the brain, as opposed to the temporal or parietal lobes.

Gliomas do not metastasize by the bloodstream, but they can spread via the cerebrospinal fluid and cause “drop metastases” to the spinal cord.
High grade gliomas are highly vascular tumors and have a tendency to infiltrate.

Treatment for recurrent childhood brain stem glioma depends on the type of tumor, whether the tumor comes back in the place in which it originated or in another part of the brain, and the type of treatment previously given.

The overall goal of the Neuro-Oncology Laboratory is to develop novel therapeutic strategies for the treatment of gliomas through an understanding, exploitation, and eventual clinical translation of the principles underlying the molecular and genetic pathogenesis of these tumors.
Although it is well recognized that human gliomas are a heterogeneous group of tumors, there are to date no pathologic classification schemas that reproducibly allow the identification of biologically similar tumors or predict for tumor-specific therapies.
The lack of such a classification schema significantly limits the ability of scientists to unravel the molecular pathogenesis of different glioma subtypes and precludes clinicians from offering therapeutic options that are specific for a patient's particular tumor.
