| Abstract | PURPOSE: To assess local control and treatment-related toxicity of single-modality radiation therapy (RT) in the treatment of imaging-defined meningiomas. METHODS AND MATERIALS: The records of Emory University School of Medicine, Atlanta, GA, were reviewed between 1985 and 2003. We identified 41 patients with 42 meningiomas treated with RT alone for lesions diagnosed on imaging alone. No patients received a histologic diagnosis. Patients in whom there was uniform agreement that the tumor represented a meningioma were accepted for therapy. Of the patients, 22 were treated with stereotactic radiosurgery (SRS), 11 with fractionated stereotactic radiotherapy (FSR), and 9 with three-dimensional conformal therapy (3DCRT). The median doses of SRS, FSR, and 3DCRT were 14 Gy, 50.4 Gy, and 52.2 Gy, respectively. RESULTS: Median follow-up was 60 months. Of 42 meningiomas, 39 were locally controlled. The 8-year actuarial local control rate by Kaplan-Meier methods was 94%. One failure occurred 6 months after 3DCRT, a second at 34 months after FSR, and a third at 125 months after SRS. A temporary symptomatic radiation-related neurologic sequela developed in 1 patient treated with SRS. No fatal treatment complications occurred. The 8-year rate for actuarial freedom from complication survival by Kaplan-Meier methods was 97%. CONCLUSIONS: RT alone is an attractive alternative to surgery for imaging-defined meningiomas without significant mass effect. It offers local control comparable to surgical resection with minimal morbidity. RT should be considered as a viable alternative to surgery for tumors in various locations. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
