Radiation therapy (RT) represents an important treatment option for patients with benign and malignant brain tumors. Recent advances in computer and imaging technology as well as radiation delivery have greatly improved the radiation oncologist's ability to deliver high doses of radiation to the tumor bed while sparing the surrounding normal tissues. This should decrease complications and perhaps increase control of local disease. Despite these advances, however, the use of radiation therapy in the management of meningiomas remains controversial, partly because these tumors grow slowly and in an unpredictable pattern. Moreover, no randomized clinical trials have been performed to test the optimal timing and effectiveness of radiotherapy in the management of patients with meningiomas. In this section, the currently available radiation-therapy techniques and their results are presented.
