Active clinical trials for "Glioma"

The purpose of this trail is to evaluate the performance of Genetron TERT PCR Kit in Glioma patients using real-time PCR method.

The purpose of this study is to characterize tumour uptake of somatostatin analog 68Ga-DOTATOC in patients with either primary or recurrent malignant glioma. The investigators hypothesis is that some primary and recurrent malignant gliomas overexpress SST2 receptor which can be imaged with 68Ga-DOTATOC PET/CT. The investigators also hypothesize that tumor uptake of 68Ga-DOTATOC correlates with immunohistochemically determined SST2 receptor status of the tumor specimen.

This is an open-label positron emission tomography/near infrared (PET/NIRF) study to investigate the imaging navigation performance and evaluation efficacy of dual modality imaging probe 68Ga-BBN-IRDye800CW in patients with lower grade glioma. A single dose of 40μg/111-148 Mega-Becquerel (MBq) 68Ga-NOTA-BBN and 1.0- or 2.0- mg/ml IRDye800CW-BBN will be injected intravenously before the operation and intraoperative respectively. Visual and semiquantitative method will be used to assess the PET images and real-time margins localization for surgical navigation.

RATIONALE: Studying the genes expressed in samples of tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. It may also help doctors predict how patients will respond to treatment. PURPOSE: This research study is looking at tissue samples from patients with glioma or other brain tumors.

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

This purpose of this study is to describe the effect of Tumor Treating Fields (NovoTTF) on quality of life (QOL), including exercise, sleep quality, and mood, in patients with World Health Organization (WHO) Grade IV malignant glioma who have been prescribed and approved to receive Optune™. This is an observational, longitudinal study, meaning that information about QOL will be collected over time while the patient is using the NovoTTF device (for example, Optune™).

The primary objective of this trial is to evaluate the seizure frequency during a course of radiotherapy for high-grade (grade III or IV) gliomas. The patients keep a seizure diary during and up to 6 weeks following radiotherapy. Every day, the patients document the number (and type) of seizures and intake of anti-epileptic medication. At the end of radiotherapy, the patients are asked to complete a questionnaire regarding their satisfaction with the seizure diary. Progression of seizure activity compared to baseline is defined as increase of frequency of seizures by more than 50%, increase of severity of seizures, or as Initiation or increase anti-epileptic medication by at least 25%. To obtain an objective assessment of seizure activity in addition to patient reported outcomes, an electroencephalography (EEG) is performed during the first and the sixth week of radiotherapy, and during the sixth week following radiotherapy. The main goal of the study is to generate objective data regarding the occurrence, frequency and severity of seizures as well as regarding the use of anti-epileptic medication during the course of radiotherapy for high-grade gliomas. These data are used to evaluate the potential effect of radiotherapy on occurrence of seizures in these patients and generate hypotheses. Therefore, statistical analyses of primary and secondary endpoints focus on descriptive methods. If statistical tests are applied, they are to be interpreted from an exploratory perspective. Thirty-two patients with documented start of radiotherapy and any documented diary data at baseline and after start of radiotherapy should be subjected to statistical analysis. Assuming that 10% of patients do not fulfil these requirements, a total of 35 patients should be enrolled to this trial. Recruitment should be completed within 12 months. With this sample size a one-sample binomial test with a one-sided significance level of 2.5% has a power of 80% to yield statistical significance if the rate of patients with progression of seizure events during the course of radiotherapy compared to baseline is 30% (rate under the alternative hypothesis) assuming a 'natural' background progression-rate of 10% without radiotherapy (null hypothesis). If the natural course of the disease would lead to a progression-rate of 5% without radiotherapy only, the power increases to 98%.

MRI elastography detects the movement of tissues in the human body and monitors their response to mechanical stress in order to reveal their mechanical properties, like palpation. These depend on the structure of the tissues, their biological conditions and possible conditions. This non-invasive technique allows exploration of deep organs such as the brain that the doctor's hand can not reach. MRI elastography may prove to be an essential tool for study, diagnosis, staging and therapeutic monitoring of brain diseases. Neurodegenerative diseases (Alzheimer's, Parkinson's, Creutzfeldt-Jakobes) and cancers largely modify the mechanical properties of the affected tissues. For a first evaluation of the technique, we are interested in glial tumors representing half of the intracranial tumors in adults (incidence: 5 cases per 100 000 inhabitants), the second cancer in children and the third cause of death in l Young adult.

The cost of particle therapy (PT) are considerably higher than conventional radiotherapy (RT) with photons. Considering potential dosimetric advantages of PT, it is necessary to determine if PT are more cost-effective than photons per indication regarding quality of life, survival, and progression free survival. Given the lack of evidence for the benefit of particle therapy in relevant cases, investigators proposed an in silico trial to investigate to what extend proton therapy decrease the amount of irradiated normal tissue and, consequently, the risk of side effects in the surrounding normal tissue as well as the risk of secondary tumors. Given validated dose-response curves and/or NTCP models, a 10% lower mean dose of proton therapy on normal tissue compared to photon therapy should result in at least a 20% lower risk of side effects.

The investigators propose a single-center, non-randomized, single-arm study at the Barrow Neurological Institute/St. Joseph's Hospital for recurrent glioma. The 5-ALA for recurrent glioma study will correlate presence of fluorescence in tumor tissue with pathological findings. This will be done using three cohorts in dose escalation. The investigators' hypothesis is that (for both low- and high-grade gliomas,) a lower dose of 5-ALA will result in less false positive fluorescence.
