Active clinical trials for "Brain Neoplasms"

To evaluate differences in intraoperative body temperature between heated huimid breathing circuit and conventional breathing circuit

This research trial studies electronic medical record review in monitoring the effects of adherence on myelosuppression and morbidity in patients with newly diagnosed brain tumors receiving temozolomide and radiation therapy. Myelosuppression is a condition in which bone marrow activity is decreased, resulting in fewer red blood cells, white blood cells, and platelets and is a side effect of some cancer treatments. Morbidity is a term that refers to having a symptom of disease or medical problems caused by a treatment. Monitoring patients' electronic medical records to compare side effects, such as myelosuppression and morbidity, with treatment adherence may be a way to enhance patient care by organizing data for medical staff.

We hope to determine the importance of different genes (including B receptors) in anthracycline-induced cardiomyopathy. This has important benefits to patients exposed to anthracyclines, as this could help determine whether certain individuals have increased susceptibility to cardiac injury.

A randomized controlled trial of a video decision aid in 50 patients with advanced brain cancer.

The goal of this study is to compare patient ratings of how severe their own symptoms may be, with their caregivers' ratings of how severe they think the patients' symptoms may be. This will be compared using a questionnaire that is given to patients with brain tumors and their caregivers. Researchers will also study any effects that these patients' neurocognitive function may have on these patients' and their caregivers' ratings of how severe the brain cancer symptoms may be.

This study is to look more closely at the tumor removed during your surgery, and to follow your condition after your treatment. The purpose of this study is to determine what side effects are common or more rare from this treatment, how well the treatment has worked for you, and to track whether you develop other brain metastases.

This study will examine patients with non-small cell lung cancer metastasis, that is, the distant spreading of tumors to the brain, and compare them with patients without brain metastasis. The molecular and genetic events that permit tumor metastasis are not well understood. There is intense investigation going on into the process in which tumor cells escape the primary local tumor, spread to distant places in the body, and find and create conditions that promote growth in those tissues. Metastasis of tumors such as lung cancer to the brain is a common problem. Tumor cells will be analyzed with the use of microarrays. A microarray is a tool for analyzing gene expression, consisting of a small membrane or glass slide containing samples of many genes arranged in a regular pattern. The goal is to identify a potential molecular signature. It is hoped that there will be discovery of why some patients are more likely than others to develop a brain metastasis, which can have a major negative effect on the quality of life and survival. Patients 18 years of age with known or evidence by radiology of a non-small cell lung cancer metastatic to the brain, either squamous cells or adenocarcinoma tumors, or those who have had a removal of a brain tumor for diagnosis or treatment may be eligible for this study. Participants will undergo the following procedures and tests: Craniotomy, that is, surgical opening of the skull, and removal of the brain tumor. Blood specimens taken from a central vein or artery before the operation, throughout as needed, and for several days afterward, to measure blood chemistries, blood count, and so forth. Physical examination and imaging of the central nervous system before and after surgery. Urine or serum, or both, pregnancy test of women of childbearing potential. Patients will also undergo blood tests at 3-month intervals after surgery for up to 5 years. The purpose is to determine if there are tumor cells in the blood, which may explain how they reached the brain.

The etiology of brain tumors is poorly understood. Due, in part, to public concern about a postulated relationship between the use of cellular telephones or other increasingly prevalent environmental exposures and the incidence of brain cancer in adults, the National Cancer Institute is collaborating with three U.S. hospitals in a comprehensive case-control study of malignant and benign brain tumors. Factors under consideration include use of cellular phones and other wireless communication devices, workplace exposures to chemical agents and electromagnetic fields, dietary factors, family history of tumors, genetic determinants of susceptibility, home appliance use, reproductive history and hormonal exposures, viruses, medical and dental exposure to ionizing radiation, and other aspects of medical history. Approximately 800 newly diagnosed brain tumor cases and 800 controls have been enrolled at hospitals in Boston, Phoenix and Pittsburgh. Cases include all adults (age greater than or equal to 18 years) newly diagnosed with a histologically confirmed intracranial glioma, intracranial meningioma or acoustic neuroma. Controls are patients admitted to the same hospitals as the cases, and treated for any of a variety of non-malignant conditions. Participating cases and controls were interviewed in the hospital by a research nurse and asked to complete a self-administered questionnaire and donate a sample of blood. Key features of the study include its large size, the emphasis on rapid ascertainment of incident cases and interview of study subjects rather than surrogate respondents, the use of detailed, job-specific questions developed by industrial hygienists to ascertain occupational exposures, and the storage of blood samples for future evaluation of inherited susceptibility, biomarkers of exposure and gene-environment interactions. Implementation of the study protocol proceeded without serious problems. There have been no harmful effects on study participants. There have been no complaints from participants or breaches of confidentiality. Continuation of this research involves analysis and reporting of results. As there will be many papers, this process is expected to extend over the next several years.

The purpose of this study is to evaluate the sensitivity and specificity of "A-PROTEIN" levels in patients with brain tumors. A-PROTEIN levels will be analyzed both pre and post treatment. Levels in blood and/or cerebrospinal fluid (CSF) will be analyzed and correlated with the underlying diagnosis and outcome.
