Surgery plus radiation therapy is used in selected cases, such as for patients with known or suspected residual disease or with recurrence after previous surgery.[2,3,4]
Radiation therapy for patients with unresectable tumors.
Grade II and III Meningioma and Hemangiopericytoma
The prognoses for patients with WHO grade II meningiomas (i.e., atypical, clear cell, and chordoid), WHO grade III meningiomas (i.e., anaplastic/malignant, rhabdoid, and papillary), and hemangiopericytomas are worse than for patients with low-grade meningiomas because complete resections are less common and the proliferative capacity is greater.[6,7] (Refer to the Meningeal Tumors section in the Classification section of this summary for more information.)
Standard treatment options:
Surgery plus radiation therapy.
Treatment options under clinical evaluation:
Patients with brain tumors that are either infrequently curable or unresectable should be considered candidates for clinical trials that evaluate interstitial brachytherapy, radiosensitizers, hyperthermia, or intraoperative radiation therapy in conjunction with external-beam radiation therapy to improve local control of the tumor. Such patients are also candidates for studies that evaluate new drugs and biological response modifiers following radiation therapy.
Current Clinical Trials
Check for U.S. clinical trials from NCI's list of cancer clinical trials that are now accepting patients with adult meningeal tumor. The list of clinical trials can be further narrowed by location, drug, intervention, and other criteria.
General information about clinical trials is also available from the NCI Web site.
