==Treatment==
Surgical removal is recommended for most types of brain tumors  in most locations, and their removal should be as complete as possible within the constraints of preservation of neurologic function. An exception to this role for surgery is deep-seated tumors such as pontine gliomas, which are diagnosed on clinical evidence and treated without initial surgery approximately 50% of the time. In most cases, however, diagnosis by biopsy is preferred. Stereotaxic biopsy can be used for lesions that are difficult to reach and resect.
Radiation therapy has a major role in the treatment of patients, as evidenced in the EORTC-22845 and MRC-BR04 trials, for example, with most tumor types and can increase the cure rate or prolong disease-free survival.  Radiation therapy may also be useful in the treatment of recurrences in patients initially treated with surgery alone.
Chemotherapy may prolong survival in patients with some tumor types and has been reported to lengthen disease-free survival in patients with gliomas, medulloblastoma, and some germ cell tumors.  Local chemotherapy with a nitrosourea applied to a polymer placed directly in the brain during surgery has been shown to be a safe modality and is under clinical evaluation.
Surgery and radiation therapy are the primary modalities used to treat tumors of the spinal axis; therapeutic options vary according to the histology of the tumor. The experience with chemotherapy for primary spinal cord tumors is rare; no reports of controlled clinical trials are available for these types of tumors. Chemotherapy is indicated for most patients with leptomeningeal involvement (from a primary or metastatic tumor) and a positive cerebrospinal fluid cytology. Most patients require treatment with corticosteroids, particularly if they are receiving radiation therapy.
For patients with brain tumors, two primary goals of surgery include:
(1) establishing a histologic diagnosis and
(2) reducing intracranial pressure by removing as much tumor as is safely possible to preserve neurological function.
Total elimination of primary intraparenchymal tumors by surgery alone is extremely rare. Radiation therapy and chemotherapy options vary according to histology and anatomic site of the brain tumor. Therapy involving surgically implanted carmustine-impregnated polymer combined with postoperative external-beam radiation therapy (EBRT) has a role in the treatment of high-grade gliomas. Dexamethasone, mannitol, and furosemide are used to treat the peritumoral edema associated with brain tumors. Use of anticonvulsants is mandatory for patients with seizures.
Novel biologic therapies under clinical evaluation for patients with brain tumors include dendritic cell vaccination, tyrosine kinase receptor inhibitors, farnesyl transferase inhibitors, viral-based gene therapy,  oncolytic viruses, epidermal growth factor receptor inhibitors and vascular endothelial growth factor inhibitors, and other antiangiogenesis agents.
Patients who have brain tumors that are either infrequently curable or unresectable should be considered candidates for clinical trials that evaluate radiosensitizers, hyperthermia, or interstitial brachytherapy used in conjunction with EBRT  to improve local control of the tumor or for studies that evaluate new drugs and biological response modifiers.
