Active clinical trials for "Brain Neoplasms"

This clinical trial studies yoga therapy in treating patients with malignant brain tumors. Yoga therapy may improve the quality of life of patients with brain tumors

Specific Aim 1: To assess the feasibility and acceptability of a home-based, computerized attention training program with survivors of central nervous system (CNS) impacting pediatric cancer (e.g. acute lymphocyte leukemia [ALL], brain tumors). Specific Aim 2: To estimate the effect size of this attention training program with survivors of childhood cancer to determine whether a larger-scale clinical trial is warranted.

The study should evaluate the biological distribution of 99mTc-1-thio-D-glucose in patients with primary brain tumors and recurrence of brain tumors. The primary objective are: To assess the distribution of 99mTc-1-thio-D-glucose in normal tissues and tumors at different time intervals. To evaluate dosimetry of 99mTc-1-thio-D-glucose. To study the safety and tolerability of the drug 99mTc-1-thio-D-glucose after a single injection in a diagnostic dosage. The secondary objective are: 1. To compare the obtained SPECT imaging results of brain tumors with the data of magnetic resonance imaging (MRI) and/or positron emission tomography (PET) and immunohistochemical (IHC) studies of postoperative material.

Since decades, neurosurgeons and neurooncologists assumed that the mass effect of brain tumors with peritumoral edema or intratumoral hemorrhage might lead to increased ICP. Therefore, decisions on surgical procedures and medical treatments were made based on clinical and radiological findings suggesting increased ICP. But in fact, no measurement has ever confirmed increased ICP in brain tumor patients. From an ethical point of view, it is not justifiable to implant an intraparenchymal ICP probe within an invasive surgical procedure in a brain tumor patient unless the patient is comatose or present with rapid impairment of the level of consciousness. Therefore, with the new medical device for non-invasive ICP measurement presented in this study protocol, we will be able to measure absolute ICP values in patients with brain tumors.

This is a prospective case-control study. This study is expected to last for approximately 12 months, comprised of 4-8 weeks of enrollment period, 28 days of treatment and 6 months of follow up. The enrollment will be completed prior to the beginning of initial treatment. The study will be closed when 10 subjects have completed the study. The recruitment will be carried out with a sample at convenience.

This pilot clinical trial studies fluorine F 18 fluorothymidine (FLT) positron emission tomography (PET)/computed tomography (CT) in measuring cell proliferation in patients with brain tumors. Comparing results of diagnostic procedures done before, during, and after treatment may help doctors measure tumor growth and plan the best treatment.

This is a randomized, double blind placebo controlled study to evaluate safety and efficacy of lucanthone administered as an adjunct to patients receiving whole brain radiation therapy (WBRT) as primary treatment for brain metastases secondary to non-small cell lung cancer.

Prognosis in patients with glioblastomas (the most aggressive high-grade glioma) remains unfavourable. Tools for improving brain tumor surgery, in particular for gliomas, are increasing. There seems to be an agreement that achieving extensive resections, when done safely without jeopardizing neurological function, improves survival. Ultrasound is currently used as a tool for providing 2D or 3D images for the purpose of tumor localization and resection control. For the use in resection control the resection cavity is filled with saline to provide acoustic coupling between the ultrasound transducer and tissue. However, attenuation of acoustic waves is very low in saline compared to the brain and this difference in attenuation is the cause of artifacts that may severely degrade the ultrasound images. Such artifacts are seen as high-intensity signal at the resection cavity wall and beyond, potentially masking small tumor remnants and generally making the interpretation of images more difficult. This research group has developed an acoustic fluid intended for use in the resection cavity instead of saline. Tests in laboratory measurements have shown that the fluid reduces artifacts and has the potential to enhance ultrasound image quality in brain tumor surgery. The investigators expect that the acoustic fluid will make it easier to detect small tumor remnants near the end of an operation, thus increasing success of glioma surgery. The purpose of this study is to test the fluid during surgery for histopathologically proven glioblastoma to assess safety and efficacy.

This phase I trial studies the best dose of vemurafenib when combined with whole brain radiation therapy (WBRT) or stereotactic radiosurgery (SRS) in patients with v-raf murine sarcoma viral oncogene homolog B (BRAF) mutation-positive melanoma and brain metastases. Radiation therapy is an effective treatment for patients with brain metastases. Patients with multiple metastases are typically treated with WBRT. For patients with a few metastases, SRS alone can be used. Vemurafenib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Combining radiation treatment with vemurafenib for melanoma patients with brain metastases may result in improved local control and prolonged survival.

The purpose of this study is to evaluate the potential of [18F]-ML-10 to serve as a non-invasive imaging tool for the early detection of apoptosis in brain metastases in response to radiation therapy. Such early detection may improve clinical management of patients with brain metastases, as it may help early identification of non-responders, and subsequently potentially lead to optimization of radiation dose, early decision on focal irradiation of selected, non-responsive lesions, or early referral of the patient to surgery. The experimental design of the present study aims to evaluate the potential of non-invasive PET examination with [18F]-ML-10, to provide the clinician early in the course of treatment, via non-invasive molecular imaging of radiation-induced apoptosis, information on tumor responsiveness, that is currently available only several weeks to months after completion of the radiotherapy.
