| Abstract | BACKGROUND: Meningiomas are the most common primary brain tumors. Resection and/or radiation therapy are the treatments of choice. Medical therapies have been investigated for inoperable, recurrent and aggressive meningiomas (grade III), but the optimal medical treatment is yet to be defined. Among biologic agents somatostatin has been found to inhibit meningioma growth due to the presence of somatostatin receptors on the surface of the tumors. AIM: We retrospectively reviewed our experience with sandostatin to assess the efficacy and toxicity in the treatment of recurrent meningiomas failing standard treatments. PATIENTS AND METHOD: A total of 17 patients (7 women and 10 men, median age 65 years) with recurrent grade I or II or III meningiomas have been studied. All patients had already been treated with multiple surgeries or radiation treatments, and all had an overexpression of somatostatin receptors by octreotide scintigraphy. Before treatment KPS ranged from 60 to 90. The patients received long-acting somatostatin on a monthly administration schedule. Radiographic response on MRI has been assessed by MacDonald Criteria. RESULTS: Patients received 3 to 18 cycles (median 9) of somatostatin. Response was as follows: PR in 1 patient, MR in 1 patient, SD in 2 patients and PD in 13 patients. Progression-free survival at 6 months was 56%, while PFS ranged from 3 to 25 months with a median of 6 months. Toxicity was uncommon (2 patients) and manageable. CONCLUSION: Long acting somatostatin displays only minor activity as salvage treatment for recurrent meningiomas after surgery and radiation therapy. |

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.
