Filter by:The purpose of this study is to determine the safety and utility of 5-aminolevulinic acid (ALA) for identifying your tumor during surgery. 5-ALA is not FDA approved at this time. When the investigators remove the tumor from your brain, it is important that they remove all of the tumor and not remove parts of normal brain. Sometimes this can be difficult because the tumor can look like normal brain. In some brain tumors, 5-ALA can make the tumors glow red under blue light. This may make it easier for your doctor to take out all of the tumor from your brain. The purpose of this study is to: - Make sure that 5-ALA helps the doctor remove more of the tumor. - Make sure 5-ALA does not cause any side effects. If you do not want to participate in this study, your doctor(s) will still do their best to remove all of the tumor in your brain. Whether or not you join this study will not change your treatment for your brain tumor.
RATIONALE: Pioglitazone hydrochloride may be effective treatment for cognitive dysfunction caused by radiation therapy. PURPOSE: This phase I trial is studying the side effects and best dose of pioglitazone hydrochloride in preventing radiation-induced cognitive dysfunction in treating patients with brain tumors.
Study Objective: Brain tumors are poorly understood. The purpose of this research is to examine whether factors in lifestyle play a role in brain tumor development. The study will also investigate the contribution of inherited susceptibility to the risk of brain cancer. By gaining a better understanding of these influences, the investigators hope to learn how to prevent brain tumors in future generations, and to develop more effective strategies for treatment. Study Protocol: This is a case-control investigation. Persons affected with a brain tumor are compared to unaffected persons on previous medical history, diet and other factors. Those enrolled in the study will participate in an interview on general background, diet, medical history and lifestyle, and will provide a sample of DNA, clippings of your toenails, and a tap water sample from your home. All procedures are performed in the clinic or through the mail. 'Cases': Cases eligible for the study are persons with a recent diagnosis of a primary brain tumor (glioma or meningioma), at least 18 years of age. 'Controls': Controls in the study are non-family members of patients, similar in age and of the same gender. Suitable controls include in-laws, friends, neighbors and co-workers.
