Filter by:Determine by a transcriptomic approach new prognostic and predictive markers in atypical meningiomas (WHO grade II). Retrospective observational study, on a cohort of 85 atypical meningiomas. Transcriptomic study first, on cryopreserved tumor samples. Then identify, thanks to the transcriptomic study, prognostic and predictive factors (study of the link between the quantity of certain RNA transcripts and progression-free survival). Finally, set up immunohistochemical applications, which can be used routinely by the pathologist.
The registry of this study was subjected to patients who were radiologically diagnosed with a non-malignant brain tumor at Seoul National University Hospital since 2001, and who have had magnetic resonance (MR) re-examination after first MR exam or will be re-examined because it was determined that immediate treatment would not be needed at the first visit to the hospital. In all MRs taken by patients, the date of imaging and the volume of the tumor are measured, and we aim to establish a natural growth history for non-malignant brain tumors.
Intra-operative blood loss of huge meningioma resection patients on average was over 1000ml. Intra-operative massive hemorrhage was associated with longer hospital of stay, higher expense, and higher mortality. Previous studies indicated intra-operative tranexamic acid infusion would decrease blood loss for cardiac, trauma and obstetric procedures. However, limited researches focusing on the effect of tranexamic acid in neurosurgery population, with heterogenous pathologies. The purpose of this study was to investigate the effect of tranexamic acid on intra-operative blood loss in patients undergoing huge meningioma resection.
The primary objective of this study is to evaluate the diagnostic performance of the CONVIVO confocal endomicroscope in discriminating between normal and abnormal tissue in vivo during brain tumor surgery. The interpretation of intraoperative images obtained in situ will be tested against conventional histologic evaluation of targeted biopsies from imaged tissue. The study team hypothesize that there will be a high degree of correlation between images obtained with the CONVIVO system and conventional histologic interpretation.
This is a two-staged, Phase 2/3, randomized, multi-center study to investigate the efficacy and safety of REC-2282 in patients with progressive NF2 mutated meningiomas.
Fractionated radiosurgery will be delivered to atypical meningioma lesions in salvage setting for patients who present post-surgical residual lesion or develop recurrence.
This multi-site, Phase 2 clinical trial is an open-label study to identify the safety, pharmacokinetics, and efficacy of a repeated dose regimen of NEO100 (perillyl alcohol) for the treatment of patients with residual high-grade meningioma following resection surgery, radiographically-confirmed progression of high-grade meningioma or recurrent high-grade meningioma. There will be up to 30 patients enrolled in this study to have 29 evaluable patients. NEO100 will be self-administered four times daily on a 28-day treatment cycle for up to twelve cycles, until disease progression or death, whichever occurs first. Following the completion of cycle twelve, patients receiving benefit will be given the option to continue receiving compassionate use treatment with NEO100.
Meningiomas are known to be the most frequent intracranial neoplasms and account for approx. 25-33% of all intracranial tumours.Targeted radionuclide therapy with radiolabelled somatostatin analogues, also called Peptide Receptor Radionuclide Therapy (PRRT), has proven to be an effective treatment in metastatic intestinal neuroendocrine tumours and is currently used in advanced, recurrent or progressive meningiomas with promising results. In this study, the therapeutic index of a standard and newly developed radiolabelled somatostatin antagonist will be evaluated and compared in PRRT. In a second step, safety and efficacy of the latter will be assessed.
This research will have a significant impact on the overall management of those cancer patients and their family members who are at risk for hereditary cancer due to germline inactivation of BAP1. Our study will ultimately facilitate the development of novel screening, prevention and treatment strategies for these individuals with the syndrome. Because the vast majority of UM develop in pre-existing nevi, characterization of individuals at high risk for development of UM will allow closer screening and earlier intervention which would improve the treatment outcome not only for retaining vision but also for overall survival. Similarly in patients with germline BAP1 mutation CM develops in premalignant atypical melanocytic lesions and careful follow up of these patients will improve the outcome of their disease. In addition this study could have impact on the management of patients with personal and/or family history of several other cancers reported in patients with germline BAP1 mutation such as mesothelioma, renal cell carcinoma, cholangiocarcinoma, hepatocellular carcinoma, meningioma and basal cell carcinoma.
Atypical meningiomas represent 15% of meningiomas. They present a high rate of recurrence, and therapeutic strategies are limited. There is a need for novel treatment strategies, such as immuotherapy. This is a retrospective study including 84 patients with primary diagnosis of atypical meningiomas. The presence of T cells (CD4, CD8, Treg and memory T cells) and mature dendritic cells will be quantified on whole tissue sections stained by immunohistochemistry (CD4, CD8, FOXP3, CD45RO and CD208). This could allow us to identify novel biomarkers for survival, and facilitate the selection of patients who may benefit from immunotherapeutic modalities.
