Meningioma medical therapy

Radiation therapy
Radiation therapy including Gamma Knife or proton beam treatment, may be pursued in cases of inoperable or unresectable tumors, or if tumor shows malignant transformation. Focused radiation may also be helpful for small tumors at the base of the skull.

Conventional chemotherapy
Conventional chemotherapy is likely not effective. Antiprogestin agents have been used, but with variable results. Recent evidence that hydroxyurea has the capacity to shrink unresectable or recurrent meningiomas is being further evaluated.
