Filter by:Cerebral blood flow (CBF) is of paramount importance to human brain function, as the brain relies on a continuous blood supply to meet its energy needs. Blockage of a cerebral blood vessel during neurosurgery, even if transient and short-lived, may result in irreversible brain tissue damage (i.e. stroke) and loss of cortical function, if not identified quickly enough. Laser speckle contrast imaging (LSCI) has been demonstrated to provide the ability to visualize flow in vessels in real time and continuously without the need for contrast agents. In LSCI, the tissue of interest is illuminated with low power laser light at red or near infrared wavelengths and the light reflected from the tissue surface is imaged onto a camera. The resulting images are laser speckle patterns and a computer processes the images to produce speckle contrast images, which are images of the motion within the field of view (ie, blood flow). The purpose of this clinical investigation is to assess the usefulness and accuracy of LSCI compared to ICGA and/or FA during neurovascular surgery. LSCI videos will be recorded automatically intraoperatively in each patient before, during, and after ICGA and/or FA in the same surgical field of view to guarantee comparability of the methods.
Evaluate the diagnostic value of TERT promoter mutation in differ glioma subtypes and expend the application of the diagnostic algorithm to surgical practice
We explores the accuracy and sensitivity of rapid intraoperative detection of IDH, TERT, BRAF indicators through a prospective clinical multi-center study. This part includes a total of 300 fresh tissue samples, paired blood samples, relevant clinical information and follow-up information from 300 patients with different grades of adult glioma. By comparing with the postoperative sequencing results, the specificity and sensitivity of intraoperative IDH and TERT rapid detection results are clear.
The investigators showed in 2015 (Guichet et al) that the Notch1 pathway has an anti-proliferative role on glial brain tumors. In this project, the investigators investigated which genes downstream of Notch1 pathway activation produce the anti-proliferative effect. The investigators hypothesized that the SNAI2 and TAL1 genes act downstream of Notch1
WHO classification of low grade gliomas now relies on tumoral molecular patterns, especially on IDH mutation and 1p/19q co deletion status. Textural analysis on medical imaging is studied in several fields, and could provide help in patients with brain tumor due to possible complications of brain biopsy. The purpose of this study is to determine if specific textural signature on MR imaging could be found for low grade gliomas. The investigators included patients with LGG diagnosed at CHU of Nice abd whose first MRI was available on the PACS of the CHU. Textural data are extraxted by tumoral contouring and specific logiciel (LifeX) and histopathologic data are assessed for each patient. Then the investigators analyze it to dtermine if textural indices can predict molecar status.
Low-grade gliomas (LGGs) are the most common intracranial tumors in children, accounting for about 40% of intracranial tumors in children. The biological characteristics and clinical prognosis of LGGs vary greatly, and they can present different biological characteristics such as restricted growth, invasive growth, and malignant transformation during their development. The prognosis of LGGs is related to the degree of tumor resection, histological type, and whether it has spread. For LGGs, surgical resection is the main treatment method. However, many tumors located in the visual pathway, brainstem, hypothalamus and other midline parts, it is impossible to completely remove. Radiotherapy can effectively control tumor progression to a certain extent, but radiotherapy can cause obvious and serious delayed damage, such as cognitive impairment, endocrine disorders, cerebrovascular events, and second tumors. Chemotherapy can effectively treat LGGs in children, and can postpone or avoid radiotherapy. It is the preferred treatment for children with LGGs after surgery. Carboplatin combined with vincristine, the CV regimen, is currently the main chemotherapy regimen for the treatment of children with LGGs. Anti-angiogenesis is a new type of treatment. Bevacizumab, a humanized monoclonal antibody that targets vascular endothelial growth factor (VEGF). Among children with relapsed, refractory or progressing LGGs, the effective rate of Bev combined with irinotecan was 44%, and the 6-month and 2-year progression-free survival rates were 85% and 48%, respectively. However, almost all of them were treated with Bev progressed again. Tumor growth is more aggressive after Bev treatment fails. Recombinant human endostatin (rh-ES) is an endogenous broad-spectrum angiogenesis inhibitor that has been shown to significantly improve therapeutic efficacy when combining with conventional chemotherapy agents in non-small-cell lung cancer, breast cancer and melanoma.Previous retrospective studies of the research team found that rh-ES combined with CV can treat LGGs in children effectively, shorten the onset time, help quickly alleviate the symptoms of brainstem damage, and improve the quality of life. This study intends to use prospective clinical studies to further confirm the efficacy and safety of the anti-angiogenic drug rh-ES combined with traditional CV regimens in the treatment of children with LGGs.
This trial assesses the quality of life in patients with high grade glioma and their caregivers using a questionnaire called the Beacon Patient Related Outcomes Quality of Life (PROQOL). Knowledge gained from this trial may help researchers find out if early integration of palliative care will lead to improvement in quality of life for both patients and caregivers.
The purpose of this research study is to learn more about seizures in people with primary brain tumors. It will evaluate whether an antiseizure medication decreases hyperexcitability activity around tumors and prevents seizures. The procedure and study drug involved in this study are: - Electrocorticography - Perampanel (Fycompa)
The evaluation of gliomas in imaging represents a real challenge today, at the initial diagnosis, for therapeutic planning or follow-up treatment of these lesions. There is an urgent need for non-invasive imaging tools to evaluate a glioma throughout its management. At present, the diagnosis of certainty is only obtained through an anatomo-pathological analysis with sampling during an invasive procedure (surgery or biopsy). Magnetic resonance imaging, through perfusion, diffusion imaging or spectroscopy is developing in gliomas. However, it remains time-consuming and is not always available. At the same time, positron emission tomography (PET) with amino acids is an interesting alternative for these brain tumours. Amino acid PET has the advantage of being more specific than the abnormalities detected in MRI and the amino acid radiotracers cross the blood-brain barrier, even if not broken, unlike Gadolinium in MRI. Among these radiotracers, 18F-FDOPA can, among other things, assist in the non-invasive staging of gliomas at initial diagnosis.
This is a prospective, single-arm, two stages, open-label, pilot study to investigate the efficacy and safety of FUS add-on bevacizumab (BEV) in rGBM patients. The BEV is the best physician's choice of standard of care for rGBM after prior radiotherapy and temozolomide chemotherapy in the LinKou Chang Gung Memorial Hospital. Eligible patients will be enrolled through the process of informed consent.
