Filter by:The purpose of this study is to determine whether newly diagnosed high-grade glioma(s) that cannot be removed surgically change as a result of the study treatment; and to identify and evaluate the potential side effects (good and bad) of the study treatment in patients with newly diagnosed high-grade glioma(s) that cannot be removed surgically.
Through the modified formulation of sodium fluorescein and methylene blue, the surface of the suspected cut edge of the patient's glioma was stained intraoperatively, and the surgical microscope image acquisition and processing system was used to determine whether the cut edge of the surgically resected tissue was positive or not. And combined with the existing multimodal surgical techniques (imaging, electrophysiology, neuronavigation and other equipment), the glioma is precisely resected.
This trial is an open-label, multicenter, phase III clinical study，conducted in patients with newly diagnosed or recurrent malignant high-grade (WHO grades 3~4) glioma, to evaluate the efficacy and safety of a single oral dose of 5-aminolevulinic acid (5-ALA) oral solution powder for fluorescence-guided tumor resection and photodynamic diagnosis.
The purpose of this study is to measure the benefit of adding abemaciclib to the chemotherapy, temozolomide, for newly diagnosed high-grade glioma following radiotherapy. Your participation could last approximately 11 months and possibly longer depending upon how you and your tumor respond.
This phase I trial tests the safety, side effects, and best dose of triapine in combination with temozolomide in treating patients with glioblastoma that has come back after a period of improvement (recurrent). Triapine inhibits an enzyme responsible for producing molecules required for the production of deoxyribonucleic acid (DNA), which may inhibit tumor cell growth. Temozolomide is in a class of medications called alkylating agents. It works by damaging the cell's DNA and may kill tumor cells and slow down or stop tumor growth. Giving triapine in combination with temozolomide may be safe, tolerable, and/or effective in treating patients with recurrent glioblastoma.
The goal of this clinical trial is to validate the safety and to assess the quality of the signals provided by newly developed micro ElectroCorticoGraphy electrodes, provided by the company Panaxium, based on conductive polymers (PEDOT:PSS) in patients suffering of gliomas during resection surgery performed in awake condition. The main questions it aims to answer are: - Safety of PEDOT:PSS microECoGs by assessing the rate of serious adverse events associated with their use during glioma surgery. - Quality of PEDOT:PSS microECoGs recordings, as compared with recordings with traditional macroelectrodes, assessed by signal-to-noise ratio, impedance, ability to detect ripples (100-250 Hz) and fast ripples (250-600 Hz), ability to record epileptic activity (spikes and equivalent) either spontaneously or following direct electrical stimulation (afterdischarges). - Practicality of microelectrodes use as perceived by neurosurgeons. - Exploratory objectives: ability to record multi-unit activity, correlation between microECoG activity and tumor infiltration - local oncometabolite concentrations, determination of epileptic seizure rate during electrode use. Participants will be recorded during awake glioma surgery by the newly developed micro ElectroCorticoGraphy electrodes and by routine macroelectrodes, as standard of care during both mapping of cortical activities and electrical stimulations used to assess the functional mapping mandatory for tailored tumor resection.
The purpose of this research study is to see if a specific type of radiation therapy, called "proton pulsed reduced dose rate" or "PRDR radiotherapy" has any benefits at dose levels and number of fractions thought to be acceptable in earlier research studies. The researchers want to find out what effects (good and bad) PRDR has on people with cancer in the brain called a "recurrent high-grade glioma" meaning that it grows fast, can spread quickly, and it has come back or gotten worse after being treated previously.
Primary brain malignant tumor has become the first lethal tumor in children and young adults, and the treatment is limited, and the prognosis of patients is poor. According to the classification of the World Health Organization, glioblastoma is divided into grade II, III and IV gliomas; The higher the degree of malignancy, the worse the clinical outcome. Among them, the most malignant, most lethal, and most common types of tumors include supratentorial glioblastoma, diffuse endopontine glioma (DIPG), medulloblastoma, and ependymoma. Its high malignancy is mainly manifested in three aspects: extremely rapid growth and obvious invasion; The operation is not easy to remove all; The tumor has a tendency of recurrence and disseminated implantation. It can occur with children and adults of all ages. At present, surgery combined with chemoradiotherapy is the main treatment, but the therapeutic effect is not good. Studies have shown that glioblastoma, as the most common primary brain malignant tumor in adults, after standard surgery, radiotherapy and chemotherapy, the median survival time is less than 15 months, and the overall five-year survival rate is only 5.4%. Even after receiving new and expensive Tumor-treating fields, the median survival time is less than 21 months. The median survival time of DIPG patients is generally less than 1 year, and the 5-year survival rate is less than 5%. The average 5-year survival rate of medulloblastoma and anaplastic ependymoma is 40%~60%. Innovative treatments are urgently needed. Immunotherapy based on Vγ9Vδ2 T cells has become a promising research direction in recent years. Its unique phosphine antigen recognition does not depend on major histocompatibility complex (MHC), easy to allograft and other advantages. Making it one of the most promising cell therapies. Brain glioma has abnormal cholesterol metabolism and phosphine antigen accumulation, which is easily sensed by Vγ9Vδ2 T cells. Therefore, the clinical exploration of Vγ9Vδ2 T cells for glioma is of great significance to both the scientific and clinical communities.
Glioblastoma is recognized as the most common and aggressive form of primary malignant brain tumor, with treatment options that are limited and prognosis that is extremely poor, showing median progression-free survival of 12 months and median overall survival of less than 18 months. Surgical resection plays a critical role in the treatment, with the extent of resection significantly impacting patient outcomes. Historical approaches to surgical resection have evolved, moving from radical strategies to more conservative ones that aim to preserve normal brain function while removing the tumor as completely as possible. Recent studies have suggested that increasing the extent of surgical resection, particularly along the T2 FLAIR border rather than the traditional T1-enhanced border, can significantly improve patient prognosis. There is, however, a lack of consensus on the optimal surgical approach, and the heterogeneity of tumors presents challenges in standardizing surgical strategies. Extended resection has been shown to prolong survival, and novel intraoperative molecular diagnostics have emerged to improve accuracy in tumor classification and prognosis. Building on these advancements, a multicenter, prospective, randomized controlled trial is proposed to evaluate the efficacy of sub-lobectomy in treating IDH wild-type/TERTp-mutant glioblastoma, aiming to improve evidence levels and establish standardized surgical practices for this devastating disease.
The goal of this clinical investigation of a medical device is to test the safety of graphene based electrodes when used during surgery for resection of brain tumors. The main questions that it aims to answer are: - To understand the safety of these new electrodes when used during brain tumor surgery (primary objective); - To assess the quality of the brain signals recorded with the new electrodes, their ability to stimulate the brain, how stable their function is over the duration of an operation, and their suitability for use in the operating theatre (secondary objectives). Participants will undergo tumor surgery as usual with the study electrodes being tested alongside a standard monitoring system. If they are awake for part of their surgery they may be asked to complete specific tasks such as naming objects from a list modified for the study. They will be monitored subsequently for any complications including undergoing an additional MRI scan 6 weeks after their surgery.
