Filter by:The purpose of this study is to collect information from medical records to see what effects proton beam radiation has on cancer and analyze possible side effects.
This phase I/II trial studies the side effects and best dose of temsirolimus when given together with perifosine and to see how well it works in treating patients with recurrent or progressive malignant glioma. Temsirolimus may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as perifosine, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving temsirolimus with perifosine may be an effective treatment for malignant glioma.
Neuroanesthesia for supratentorial surgery involves a thorough understanding of the physiopathology of intracranial pressure, cerebral homeostasis and regulation of cerebral perfusion pressure as well as the effects of anesthesia and surgery on these elements. The main objective of anesthesia during neurosurgery is to preserve the integrity of the brain by maintaining cerebral homeostasis, and assuring cerebral protection using normovolemia, normotension, normoglycemia, moderate hyperoxia and hypocapnia and hyperosmolality with the administration of mannitol. During surgery, the use of surgical retractors must be limited to avoid possible ischemia of the brain tissue. Surgical retractors can be replaced by chemical retractors. The concept of chemical retraction involves a reduction of cerebral blood flow, maintaining cerebral perfusion pressure, moderate hyperventilation, drainage of cerebrospinal fluid and osmotherapy. Mannitol, an osmotic agent, has been widely used to reduce the volume of the brain, the intracranial pressure and to facilitate the surgical approach in reducing the risk of cortical lesions during the opening of the skull. Mannitol 20% is usually given intravenously in bolus doses of 0.5-1g/kg over 30 minutes. However, over the last few years, the concept of a dose-response relationship has emerged. Some recent studies tend to demonstrate that higher doses of mannitol could reduce intracranial pressure significantly without any important side effects. The main objective of the present study is to compare two doses of mannitol (0.7 and 1.4 g/kg) on brain relaxation during supratentorial craniotomies.
RATIONALE: Armodafinil may help relieve fatigue and improve quality of life in patients with cancer receiving radiation therapy to the brain. PURPOSE: This clinical trial is studying how well armodafinil works in treating fatigue caused by radiation therapy in patients with primary brain tumors.
RATIONALE: Specialized radiation therapy, such as proton beam radiation therapy, that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue. PURPOSE: This phase I/II trial is studying the best way to give proton beam radiation therapy and to see how well it works in treating patients with low grade gliomas.
RATIONALE: Diagnostic procedures, such as magnetic resonance imaging, may help doctors predict a patient's response to treatment and help plan the best treatment. PURPOSE: This clinical trial is studying magnetic resonance imaging in response to radiation therapy in patients with high grade glioma.
The purpose of this study is to estimate the rate of local control at the treated site of the metastasis as a function of 1mm versus 3mm expansion about the gross tumor volume (GTV). Each lesion, not each patient will be ranndomized to either the 1mm or 3mm margin with 40 lesions randomized to each arm.
RATIONALE - Fractionated radiotherapy uses high-energy photons to kill, or damage tumor cells. High daily dose temozolomide combined with fractionated radiotherapy may make tumor cells more sensible to treatment. PURPOSE - This randomized phase II trial, assess in patients with brain metastases from solid tumors, whether the whole brain radiotherapy (WBRT) plus temozolomide is able to improve the results obtained with WBRT.
Standard treatment for patients with diffuse pontine tumors is radiation therapy, but less than 10% of patients are cured. Adding standard chemotherapy has not improved the cure rate. Standard treatment for high-grade astrocytomas is surgery and radiation. The surgeon removes as much of the tumor as she or he can. Radiation after that tries to kill any cancer cells that are left. Some patients also get chemotherapy. These are anti-cancer drugs. They can be given during or after radiation. Current standard treatments do not cure many patients. In this study the doctors are adding a new medication called cetuximab to the treatment and will also use a chemotherapy medication (irinotecan) that has been promising for patients treated for recurrent disease.
