Active clinical trials for "Oligodendroglioma"

Background: - The blood-brain barrier helps to protect the central nervous system (brain and spinal cord) from harmful toxins, but also prevents potentially useful chemotherapy from reaching brain tumors. The barrier is formed by tight connections between blood vessel cells and molecules found on the surface of brain blood vessels such as Permeability-glycoprotein (Pgp). Pgp may influence whether patients with brain tumors known as gliomas respond to chemotherapy and what side effects they may experience. The compound (11C)N-desmethyl-loperamide ((11C)dLop) reacts to Pgp molecules, and therefore may be used with positron emission tomography (PET) imaging to study the blood brain barrier. Objectives: - To study the ability of PET imaging with (11C)dLop to evaluate the blood brain barrier in brain tumor patients. Eligibility: - Individuals at least 18 years of age who have a brain tumor with characteristics that may be imaged with techniques such as magnetic resonance imaging (MRI) andPET. Design: Participants will be screened with a full physical examination and medical history, blood and urine tests, and tumor imaging studies (fluorodeoxyglucose PET and MRI scans with contrast agent). The (11C)dLop scan will take 1 hour to perform. Participants will be asked to return for blood and urine tests approximately 24 hours after the PET scan. Participants will have followup visits at least every 4 months by repeating a complete history and physical exam and brain MRI. Participants may have repeat scans with (11C)dLop at various points in the course of cancer treatment, but will not have these scans more than twice in a 12-month period. Participants will be followed for as long as possible during treatment to see if imaging with (11C)dLop correlates with response to the treatments.

The purpose of this study is to evaluate the safety and biologically active dose of TM-601 in adult patients with recurrent malignant glioma.

The purpose of this study is to evaluate the safety and effectiveness of 131I-TM601 in the treatment of adult patients with progressive or recurrent malignant gliomas.

Low grade gliomas (LGGs) are the most common primary central nervous system malignancies. Brain surgeries with the most possible extent of resection are endeavored to achieve longer survivals in LGG patients. For patients with tumor located in eloquent areas so that gross total resection is not applicable, National Comprehensive Cancer Network (NCCN) 2013 guidelines assigned both radiotherapy or chemotherapy as adjuvant treatments of low grade glioma following surgeries. Retrospective studies have suggested that temozolomide (an oral chemotherapeutics) chemotherapy have good effects on the control of tumor progression or recurrence in LGG patients after surgeries, especially in those with isocitrate dehydrogenase (IDH) gene mutations. Therefore, our prospective cohort study is to provide a higher level(IIb) of evidence for the correlation between IDH mutation and the responsiveness to up-front adjuvant metronomic temozolomide chemotherapy in young patients with LGG located in eloquent brain areas. And hopefully justify future RCTs with comparison between effects of adjuvant radiotherapy and chemotherapy in these patients.

The purpose of the study is to determine the safety and efficacy of intracranially implanted Carmustine in the treatment of patients with recurrent malignant glioma.

The purpose of the study is to confirm the safety of the selected dose and potential toxicity of oncolytic poliovirus (PV) immunotherapy with PVSRIPO for pediatric patients with recurrent WHO grade III or IV malignant glioma, but evidence for efficacy will also be sought. The primary objective is to confirm the safety of the selected dose of PVSRIPO when delivered intracerebrally by convection-enhanced delivery (CED) in children with recurrent WHO Grade III malignant glioma (anaplastic astrocytoma, anaplastic oligoastrocytoma, anaplastic oligodendroglioma, anaplastic pleomorphic xanthoastrocytoma) or WHO Grade IV malignant glioma (glioblastoma, gliosarcoma). A secondary objective is to estimate overall survival (OS) in this population.

The purpose of the study is to determine the clinical safety and operability of the innovative tissue imprint device ProTool.

This trial studies the natural history of brain function, quality of life, and seizure control in patients with brain tumor who have undergone surgery. Learning about brain function, quality of life, and seizure control in patients with brain tumor who have undergone surgery may help doctors learn more about the disease and find better methods of treatment and on-going care.

According to the O.M.S. Classification, grade 2 glioma is a pre-cancerous lesion, slowly progressive, infiltrating the central nervous system, mainly affecting young adults. This surgery should nevertheless be conducted in awake condition to achieve two conflicting goals: get maximum brain tissue infiltrated by the tumor while preserving the integrity of functional structures. So awake after opening the skull, the patient undergoes a series of preoperative tests, administered by a speech therapist present in the operating room. This procedure allows the neurosurgeon to establish an individual functional brain mapping in real time, through the observation by the SLP of the patient's answers to direct electrical stimulation applied to the cortical and sub-cortical. This support is based on the extraordinary plasticity demonstrated by the brain in the presence of a slowly progressive lesion. To ensure the patient the highest achievable load should increase our understanding of brain function, including the neural bases of language, glioma grade 2 is predominantly localized functional area of language.

Patients diagnosed with oligodendroglioma with a specific molecular profile represent rare tumour groups (about 10% of adult gliomas) with relatively favourable prognosis (median survival between 8 and 12 years). These patients are often treated with surgery, chemotherapy and/or radiotherapy. However, as patients live for a long period of time, they may also experience long-term toxic side-effects of treatment. The long-term consequences of treatment- and disease-related factors on quality of life and cognitive functioning of these patients are largely unknown. This study aims to investigate quality of life and cognitive functioning in long-term survivors of oligodendroglioma (with IDH mutation and 1p/19q codeletion). This knowledge can support health care professionals prepare patients for any long-term consequences of treatment.
