Active clinical trials for "Brain Neoplasms"

MRI is used in clinical routine for diagnosing brain tumors, but has limitations in identifying tumor grade, true tumor extension and differentiate viable tumor tissue from treatment induced changes and recurrences. Amino acid PET has demonstrated a great potential for defining true tumor volume, differentiate viable tumor tissue from postoperative changes or radiation necrosis, selection of biopsy site, non-invasive grading of gliomas and for treatment planning and therapy response assessment. By combining PET with MRI, the diagnostic accuracy can improve significantly for these patients. More research is however needed to compare the most promising amino acid PET tracers in patients with glioma, but also to assess the diagnostic value of amino acid PET in patients with different brain metastases, where the knowledge concerning the uptake characteristics is limited. Three of the most promising amino acid tracers ([11C]-methyl-methionine (11C-MET), [18F] fluoro-ethyl-tyrosin (18F-FET) and anti-1-amino-3-[18F]fluorocyclobutane-1-carboxylic acid (18F-FACBC)) will be evaluated in 3 substudies in this project; WP1 Aminoacid PET/MRI in low and high grade glioma; WP2 Role of 11C-MET in high-grade glioma Gamma Knife® radiosurgery; and WP3 Amino acid PET in brain metastasis. The main aim of the study is to improve diagnostic accuracy, histopathological tissue sampling, delineation of tumor extent and therapy response assessment in gliomas and brain metastases with amino acid PET/MRI.

The purpose of this study is to test the accuracy of using an imaging technique called breath-holding functional magnetic resonance imaging (BH fMRI) in addition to the standard imaging test described above. This study will allow the researchers to find out whether using BH fMRI in combination with the standard approach is the same as, better, or worse than the standard approach used alone.

This trial is a paucicentric, clinico-biological cohort study with retrospective and prospective enrollment, aiming to identify biomarkers predictive of response to Proton Beam Therapy (PBT) in cancer patients (high grade sarcoma, brain tumors and meningioma). This study include collection of clinical data, of tumor samples (collected during standard of care) and a blood sample for alive patients.

This clinical study is a parallel, prospective observational single-centre trial in patients presenting with 5 to 30 brain metastases. Patients to receive either stereotactic radiosurgery (SRS) alone or SRS plus whole brain radiation (WBRT) will be enrolled.

The purpose of this study is to test if PET scans using 89Zr-DFO-cRGDY-PEG-Cy5-C' dot particles, can be used to take pictures of brain tumors. The investigators want to understand how the particles are distributed and removed from the body, which may help others be treated in the future. This will be the first time that 89Zr-DFO-cRGDY-PEG-Cy5-C' dot particles are being used in people. The amount of particles given in this study is very small compared to the amount that was used in mice animal studies.

The objective of the International Rare Brain Tumor Registry (IRBTR) is to better understand rare brain tumors through the collection of biospecimens and matched clinical data of children, adolescents, and young adult patients diagnosed with rare brain tumors.

This study determines whether non-invasive evaluation using repeated magnetic resonance imaging (MRI) scans and repeated blood biomarker measurements can be used to predict changes in a person's mental functions that result from radiation exposure to the brain. This study may let researchers monitor patient responses to treatment and the disease better and possibly make changes to patient treatment, if needed.

The goals of this study are to: To improve upon and develop new innovative magnetic resonance imaging techniques that refine image quality and enhance performance. Improvements in these areas will have positive implications for medical diagnosis and treatment. To correlate MRI images with underlying disease pathophysiology in order to ensure that imaging accurately reflects the disease process.

This study represents a survivorship protocol that focuses on cognition and health-related quality of life (HRQoL) in cancer patients that have received prior brain irradiation. The primary purpose of this study is to assess the feasibility of using a digital symptom tracking application focused on HRQoL and cognition in cancer survivors who received brain irradiation.

The aim of this study is to collect systematically and proactively data regarding the performance of Neuro-Patch, like complications and handling, under daily clinical practice when used as intended by the manufacturer
