Active clinical trials for "Brain Neoplasms"

Background: Primary or secondary brain tumors (metastases) remain associated with a very poor prognosis linked to significant therapeutic resistance. Thus, glioblastoma, which is the most common and aggressive primary brain tumor in adults, is associated with inevitable relapses within 7 to 10 months and median survival of approximately 12 to 14 months. At the same time, brain metastases are increasingly increasing following better systemic control of other metastatic sites and improvement in detection methods. However, they remain resistant to the latest therapeutic innovations such as immunotherapies or targeted therapies. In this context, innovative strategies are necessary to identify new therapeutic targets and implement new treatments to overcome resistance phenomena in the clinic. Objective: Our goal will be to generate tumoroids and stem-like cell lines (PDX) from patient tumor samples. Methods: We will establish tumor tumoroids and stem cell lines from patient samples. These preclinical models will allow us to test a large number of drugs, quickly and efficiently thanks to models as close as possible to patient tumors and limiting the use of animal models (3R). Overall, this project should enable major advances in the treatment of glioblastoma and brain metastases and enable the rapid testing of new molecules in clinical trials thanks to the homology of our models with our patients' diseases.

In this proposal, the investigators introduce a novel, translational study to prospectively examine primary brain tumor patients undergoing fractionated radiation therapy to the brain. Quantitative neuroimaging, radiation dose information, and directed neurocognitive testing will be acquired through this study to improve understanding of cognitive changes associated with radiation dosage to non-targeted tissue, and will provide the basis for evidence-based cognitive- sparing brain radiotherapy.

This study evaluates patient perceptions around quality of care through telemedicine in neuro-oncology. Studying questionnaires related to perceptions quality of care through telemedicine in patients with brain cancer may help doctors to improve the delivery of care through this modality.

Background: Neurobehavioral functions and quality of life (QoL) are the important outcome measurements after radiotherapy in patients with brain tumors and even head/neck cancers. However, few studies have focused on neurobehavioral functions and QoL after anti-cancer treatment particularly brain radiotherapy for pediatric/adolescent patients with brain tumors. This study thus aims to prospectively evaluate those functions in pediatric or adolescent patients with brain or head/neck tumors in order to provide useful information about their clinical outcomes. Methods: A total of 72 pediatric/adolescent patients, who are diagnosed with brain tumors or head/neck cancers, were prospectively recruited. Neurobehavioral functions will be evaluated using a neuropsychological battery, which includes general cognitive functions, intelligence, memory, executive functions, information processing and emotional/behavioral expressions. The QoL will be evaluated by the health-related QoL questionnaire. All participants will be examined at six phases, which include pre-treatment, 1-month post-treatment, 4-month post-treatment, 1-year post-treatment, 2-year post-treatment and 3-year post-treatment. Expected results: Patients'neurobehavioral functions and QoL will show significant improvement after treatment, and the improvement will not be diminished across each post-treatment phase.

This pilot clinical trial studies fluorine F 18 fluorodopa (18F-DOPA)-positron emission tomography (PET) in planning surgery in patients with gliomas. New imaging procedures, such as 18F-DOPA-PET scan, may help find gliomas and may help in planning surgery.

Removing a tumor from a patients brain is hard to do because, very often, brain tumors do not have boundaries that are easy for the patients surgeon to find. In many cases, the surgeon can't tell exactly where the tumor begins or ends. The surgeon usually can remove most of the patient's tumor by looking at the MRI images that were taken of the patient's brain before surgery. However, the surgeon does not have any good way to tell if the entire tumor has been removed or not. Removing the entire tumor is very important because leaving tumor behind may allow it to grow back which could decrease the chances of survival.

Brain metastasis (BrM) develops in approximately 40% of cancer patients. Stereotactic radiosurgery (SRS) is a form of radiotherapy that delivers high-dose per fraction to individual lesions that is commonly used to treat BrM. Radionecrosis (RN) is an adverse event that occurs in approximately 10 - 25% of patients 6 - 24 months after treatment with SRS. Tumour progression may also occur due to local failure of treatment. Radionecrosis and tumour progression share very similar clinical features including vomiting, nausea, and focal neurologic findings. Radionecrosis and tumour progression also share overlapping imaging characteristics. Due to their similarities, physicians need to perform a surgical resection to diagnose the complication. By using a hybrid FLT-PET/MRI scan, the investigators propose that this combination scan will provide robust data with which to differentiate between radionecrosis and tumour progression without the need for surgery. The investigators plan to conduct a single center feasibility study to investigate the potential in differentiating between SRS and tumour progression in patients who have previously undergone SRS for BrM who are suspected to have either RN or tumour progression using hybrid FLT-PET/MRI imaging.

This study is to collect data about how 18FPARPi can be used together with PET/positron emission tomography and MRI/magnetic resonance imaging scans to take pictures of brain cancer

The primary objectives of this study are: Determine the percentage of patients whose surgical plan would change with FET-PET/MRI compared to MRI alone. Determine the percentage of patients who have residual tumor after surgery detected with FET-PET/MRI. A secondary objective of this study is: 1) Perform preliminary correlations between the pre- and post-surgical metabolic tumor volumes measured with FET-PET/MRI to progression free survival.

The aim of this prospective observational study is to identify the specific reasons that prolong a hospital stay after elective tumor craniotomy. Optimal postoperative in-hospital stay is considered to be two days from surgery to discharge from the neurosurgical ward. However, a variable length of stay at a neurological department for follow-up of late recognized deficits of neurological consequences of the surgical procedure are common.
