Filter by:The purpose of this study is to collect and store brain tissue samples and blood from children with brain cancer that will be tested in the laboratory. Collecting and storing samples of tumor tissue and blood from patients to test in the laboratory may help the study of cancer in the future.
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.
The purpose of this research study is to evaluate the effectiveness and safety of SOM230C in treating recurrent meningiomas. SOM230C is a newly discovered drug that may stop meningioma cells from growing abnormally. This drug has been used in treatment of other tumors, and information from those other research studies suggests that SOM230C may help to stop the growth of meningiomas.
Meningiomas account for 20% of primary adult brain tumors, occurring at an annual incidence of 6 per 100,000 (Louis, Scheithauer et al. 2000). Complete surgical resection is the treatment of choice but may not possible when the tumor invades critical structures (e.g., skull base, sagittal sinus) (Mirimanoff, Dosoretz et al. 1985; al-Rodhan and Laws 1990; Al-Rodhan and Laws 1991; Newman 1994; De Monte 1995; Levine, Buchanan et al. 1999; Barnett, Suh et al. 2000; Ragel and Jensen 2003). Up to 20% of meningiomas exhibit a more aggressive phenotype that does not respond to standard therapies (Kyritsis 1996). Adjuvant therapies are critical for patients with this subset of meningiomas. Radiation therapy and stereotactic radiosurgery are good adjuvant therapies but are limited by radiation neurotoxicity, tumor size constraints, and injury to adjacent vascular structures or cranial nerves (Goldsmith, Wara et al. 1994; Barnett, Suh et al. 2000; Goldsmith and Larson 2000). Standard chemotherapeutic treatments have been disappointing (Kyritsis 1996). Even drugs like temozolomide that have shown efficacy against malignant brain tumors have failed to inhibit the growth of refractory meningiomas in a phase II study (Chamberlain, Tsao-Wei et al. 2004).
The purpose of this study is to find out what effects, good and/or bad, sunitinib has on patients and their tumors. At this time, no drugs are routinely used to treat meningioma, hemangioblastoma or hemangiopericytoma. Only surgery and radiation therapy are known to be useful. Sunitinib is a drug approved for advanced kidney cancer. Sunitinib is also being studied for other tumors. It may be useful in the treatment of brain tumors because it can prevent formation of new blood vessels that allow tumor cells to survive and grow.
Bevacizumab may reduce CNS side effects caused by radiation therapy. This randomized phase II trial is studying how well bevacizumab works in reducing CNS side effects in patients who have undergone radiation therapy to the brain for primary brain tumor, meningioma, or head and neck cancer.
This phase I trial is studying the side effects and best dose of ispinesib in treating young patients with relapsed or refractory solid tumors or lymphoma. Drugs used in chemotherapy, such as ispinesib, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing
RATIONALE: Imatinib mesylate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as hydroxyurea, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving imatinib mesylate together with hydroxyurea may kill more tumor cells. PURPOSE: This phase II trial is studying how well giving imatinib mesylate together with hydroxyurea works in treating patients with recurrent or progressive meningioma.
RATIONALE: Vatalanib may stop the growth of tumor cells by blocking blood flow to the tumor and by blocking some of the enzymes needed for cell growth. PURPOSE: This phase II trial is studying how well vatalanib works in treating patients with recurrent or progressive meningioma.
This phase I trial is studying the side effects and best dose of AZD2171 in treating young patients with recurrent, progressive, or refractory primary CNS tumors. AZD2171 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor.
