Brain And Central Nervous System Tumor clinical trials at UC Health
6 in progress, 1 open to new patients

RATIONALE: Sometimes a tumor may not need treatment until it progresses. In this case, observation may be sufficient. Specialized radiation therapy that delivers a high dose of radiation directly to the tumor, such as 3-dimensional conformal radiation therapy and intensity-modulated radiation therapy, may kill more tumor cells and cause less damage to normal tissue. It is not yet known whether observation is more effective than radiation therapy in treating patients with meningioma.

PURPOSE: This phase II trial is studying observation to see how well it works compared with radiation therapy in treating patients with grade I, grade II, or grade III meningioma.

RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving radiation therapy together with temozolomide may kill more tumor cells. It is not yet known whether giving temozolomide during and/or after radiation therapy is more effective than radiation therapy alone in treating anaplastic glioma.

PURPOSE: This randomized phase III trial is studying giving temozolomide during and/or after radiation therapy to see how well it works compared to radiation therapy alone in treating patients with anaplastic glioma.
